TABLE OF CONTENTS

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

The prospectus and this prospectus supplement, including the documents incorporated by reference into the prospectus and this prospectus supplement, contain both historical and forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”), and Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the “U.S. Exchange Act”), and forward-looking information within the meaning of Canadian securities laws (collectively, “forward-looking statements”). This information has been included to provide readers with information about the Corporation and its subsidiaries and affiliates, including management’s assessment of the Corporation’s and its subsidiaries’ future plans and operations. This information may not be appropriate for other purposes. Forward-looking statements are typically identified by words such as “anticipate”, “believe”, “estimate”, “expect”, “forecast”, “intend”, “likely”, “plan”, “project”, “target”, and similar words suggesting future outcomes or statements regarding an outlook. Forward-looking information or statements included or incorporated by reference in the prospectus and this prospectus supplement include, but are not limited to, statements with respect to the following: the Corporation’s corporate vision and strategy, including strategic priorities and enablers; the COVID-19 pandemic and the duration and impact thereof; energy intensity and emissions reduction targets and related environmental, social and governance matters; diversity and inclusion goals; expected supply of, demand for, and prices of crude oil, natural gas, natural gas liquids (“NGL”), liquified natural gas and renewable energy; energy transition; anticipated utilization of the Corporation’s existing assets; expected earnings before interest, income taxes and depreciation and amortization (“EBITDA”); expected earnings/(loss); expected future cash flows and distributable cash flow; dividend growth and payout policy; financial strength and flexibility; expectations on sources of liquidity and sufficiency of financial resources; expected strategic priorities and performance of the Liquids Pipelines, Gas Transmission and Midstream, Gas Distribution and Storage, Renewable Power Generation and Energy Services businesses; expected costs related to announced projects and projects under construction; expected in-service dates for announced projects and projects under construction and for maintenance; expected capital expenditures, investment capacity and capital allocation priorities; expected equity funding requirements for the Corporation’s commercially secured growth program; expected future growth and expansion opportunities; expectations about the Corporation’s joint venture partners’ ability to complete and finance projects under construction; expected closing of acquisitions and dispositions and the timing thereof; expected benefits of transactions, including the realization of efficiencies, synergies and cost savings; expected future actions of regulators and courts; toll and rate cases discussions and filings, including Mainline System contracting; anticipated competition; United States Line 3 Replacement Program, including anticipated in-service dates and capital costs; Line 5 dual pipelines and related litigation and other matters; and this offering, including the closing date thereof, the expected use of proceeds and the Corporation’s intention to not list the Notes on any stock exchange or other market.

Although the Corporation believes these forward-looking statements are reasonable based on the information available on the date such statements are made and processes used to prepare the information, such statements are not guarantees of future performance and readers are cautioned against placing undue reliance on forward-looking statements. By their nature, these statements involve a variety of assumptions, known and unknown risks and uncertainties and other factors, which may cause actual results, levels of activity and achievements to differ materially from those expressed or implied by such statements. Material assumptions include assumptions about the following: the COVID-19 pandemic and the duration and impact thereof; the expected supply of and demand for crude oil, natural gas, NGL and renewable energy; prices of crude oil, natural gas, NGL and renewable energy; anticipated utilization of assets; exchange rates; inflation; interest rates; availability and price of labor and construction materials; operational reliability; customer and regulatory approvals; maintenance of support and regulatory approvals for the Corporation’s projects; anticipated in-service dates; weather; the timing and closing of acquisitions and dispositions and of this offering; the realization of anticipated benefits and synergies of transactions; governmental legislation; litigation; estimated future dividends and impact of the Corporation’s dividend policy on its future cash flows; the Corporation’s credit ratings; capital project funding; hedging program; expected EBITDA; expected earnings/(loss); expected future cash flows; and expected distributable cash flow. Assumptions regarding the expected supply of and demand for crude oil, natural gas, NGL and renewable energy, and the prices of these commodities, are material to and underlie all forward-looking statements, as they may impact current and future levels of demand for the Corporation’s services. Similarly, exchange rates, inflation, interest rates and the COVID-19 pandemic impact the economies and business environments in which the Corporation operates

S-iii

TABLE OF CONTENTS

and may impact levels of demand for the Corporation’s services and cost of inputs, and are therefore inherent in all forward-looking statements. Due to the interdependencies and correlation of these macroeconomic factors, the impact of any one assumption on a forward-looking statement cannot be determined with certainty, particularly with respect to expected EBITDA, expected earnings/(loss), expected future cash flows, expected distributable cash flow or estimated future dividends. The most relevant assumptions associated with forward-looking statements regarding announced projects and projects under construction, including estimated completion dates and expected capital expenditures, include the following: the availability and price of labor and construction materials; the effects of inflation and foreign exchange rates on labor and material costs; the effects of interest rates on borrowing costs; the impact of weather and customer, government, court and regulatory approvals on construction and in-service schedules and cost recovery regimes; and the COVID-19 pandemic and the duration and impact thereof.

The Corporation’s forward-looking statements are subject to risks and uncertainties pertaining to the successful execution of the Corporation’s strategic priorities, operating performance, legislative and regulatory parameters; litigation, including with respect to the US L3R Program, Dakota Access Pipeline and Line 5 dual pipelines; acquisitions, dispositions and other transactions and the realization of anticipated benefits therefrom; the Corporation’s dividend policy; project approval and support; renewals of rights-of-way; weather; economic and competitive conditions; public opinion; changes in tax laws and tax rates; exchange rates; interest rates; commodity prices; political decisions; the supply of, demand for and prices of commodities; and the COVID-19 pandemic, including but not limited to those risks and uncertainties discussed in the prospectus, this prospectus supplement and in documents incorporated by reference into the prospectus and this prospectus supplement. The impact of any one risk, uncertainty or factor on a particular forward-looking statement is not determinable with certainty as these are interdependent and the Corporation’s future course of action depends on management’s assessment of all information available at the relevant time. Except to the extent required by applicable law, the Corporation assumes no obligation to publicly update or revise any forward-looking statement made in the prospectus and this prospectus supplement or otherwise, whether as a result of new information, future events or otherwise. All forward-looking statements, whether written or oral, attributable to the Corporation or persons acting on the Corporation’s behalf, are expressly qualified in their entirety by these cautionary statements.

For more information on forward-looking statements, the assumptions underlying them, and the risks and uncertainties affecting them, see “Note Regarding Forward-Looking Statements” in the prospectus and “Risk Factors” in this prospectus supplement and the prospectus.

Risk Factors

Lack of Public Market for the Notes

The 20 Notes and the 20 Notes are each new issues of securities with no established trading market. The Existing 2051 Notes are not listed on any securities exchange and we do not intend to apply for listing of any series of Notes on any securities exchange.

Conflicts of Interest

We may have outstanding existing indebtedness owing to certain of the underwriters and affiliates of the underwriters, a portion of which we may repay with the net proceeds of this offering. See “Use of Proceeds” in this prospectus supplement. As a result, one or more of the underwriters or their affiliates may receive more than 5% of the net proceeds from this offering in the form of the repayment of existing indebtedness. Accordingly, this offering is being made pursuant to Rule 5121 of the Financial Industry Regulatory Authority, Inc. Pursuant to this rule, the appointment of a qualified independent underwriter is not necessary in connection with this offering, because the conditions of Rule 5121(a)(1)(C) are satisfied.

TABLE OF CONTENTS

RISK FACTORS

You should consider carefully the following risks and other information contained in and incorporated by reference into this prospectus supplement and the accompanying prospectus before deciding to invest in the Notes of any series. In particular, we urge you to consider carefully the following risk factors, as well as the risk factors set forth under the heading “Item 1A. Risk Factors” in the Corporation’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, incorporated by reference into this prospectus supplement and the accompanying prospectus. The following risks and uncertainties could materially and adversely affect our financial condition and results of operations. In that event, the value of our securities, including the Notes, or our ability to meet our obligations under the Notes, may be adversely affected.

Risks Related to the Notes

We are a holding company and as a result are dependent on our subsidiaries to generate sufficient cash and distribute cash to us to service our indebtedness, including the Notes.

Our ability to make payments on our indebtedness, fund our ongoing operations and invest in capital expenditures and any acquisitions will depend on our subsidiaries’ (including subsidiary partnerships and joint-ventures through which we conduct business) ability to generate cash in the future and distribute that cash to us. It is possible that our subsidiaries may not generate cash from operations in an amount sufficient to enable us to service our indebtedness, including the Notes of any series. The Notes are U.S. dollar-denominated obligations and a substantial portion of our subsidiaries’ revenues are denominated in Canadian dollars. Fluctuations in the exchange rate between the U.S. and Canadian dollars may adversely affect our ability to service or refinance our U.S. dollar-denominated indebtedness, including the Notes.

The Notes are structurally subordinated to the indebtedness of our non-Guarantor subsidiaries.

The Notes are not guaranteed by our subsidiaries (including subsidiary partnerships and joint ventures through which we conduct business) that are not Guarantors and are thus structurally subordinated to all of the debt of these subsidiaries. Additionally, each of the Guarantors will be released from its guarantees following the repayment in full or discharge or defeasance of the Guarantor’s debt securities outstanding as of January 22, 2019, or upon the occurrence of certain other events, as described under “Description of the Notes and the Guarantees — Guarantees” in this prospectus supplement, in which case the Notes will be structurally subordinated to all of the debt of that former guarantor subsidiary. The Corporation’s interests in its subsidiaries and the partnerships and joint ventures through which it conducts business generally consist of equity interests, which are residual claims on the assets of those entities after their creditors are satisfied. As at June 30, 2021, the long-term debt (excluding current portion, as well as guarantees and intercompany obligations between the Corporation and its subsidiaries) of the subsidiaries of the Corporation other than the Guarantors totaled approximately $25,170 million.

The Indenture restricts our ability to incur liens, but places no such restriction on our subsidiaries or the partnerships and joint ventures through which we conduct business. Holders of parent company indebtedness that is secured by parent company assets will have a claim on the assets securing the indebtedness that is prior in right of payment to our general unsecured creditors, including you as a holder of the Notes (a “Noteholder”). The Indenture permits us to incur additional liens as described under “Description of the Notes and the Guarantees — Covenants — Limitation on Security Interests” in this prospectus supplement.

Your right to receive payments on the Notes is effectively subordinate to those lenders who have a security interest in the assets of the Corporation or the Guarantors.

The Notes and the related guarantees are unsecured. The Corporation or the Guarantors may incur indebtedness that is secured by certain or substantially all of their respective tangible and intangible assets, including the equity interests of each of their existing and future subsidiaries. If the Corporation or the Guarantors were unable to repay any such secured indebtedness, the creditors of those obligations could foreclose on the pledged assets to the exclusion of Noteholders, even if an event of default exists under the Indenture at such time. As at June 30, 2021, SEP and EEP had no secured indebtedness outstanding.

These redemption rights may, depending on prevailing market conditions at the time, create reinvestment risk for the Noteholders of a series of Notes in that they may be unable to find a suitable replacement investment with a comparable return to those Notes.

Federal and state statutes allow courts, under specific circumstances, to void the guarantees of the Notes by our Guarantors and require the Noteholders to return payments received from the Guarantors.

Under U.S. bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee can be voided, or claims under the guarantee may be subordinated to all other debts of that guarantor if, among other things, the guarantor, at the time it incurred the indebtedness evidenced by its guarantee or, in some states, when payments become due under the guarantee:

•

received less than reasonably equivalent value or fair consideration for the incurrence of the guarantee and was insolvent or rendered insolvent by reason of such incurrence;

•

was engaged in a business or transaction for which the guarantor’s remaining assets constituted unreasonably small capital; or

•

intended to incur, or believed that it would incur, debts beyond its ability to pay those debts as they mature.

A guarantee may also be voided, without regard to the above factors, if a court found that the guarantor entered into the guarantee with the actual intent to hinder, delay or defraud its creditors. A court would likely find that a guarantor did not receive reasonably equivalent value or fair consideration for its guarantee if the guarantor did not substantially benefit directly or indirectly from the issuance of the Notes. If a court were to void a guarantee with respect to the Notes of any series, the applicable Noteholders would no longer have a claim against the applicable Guarantor. Sufficient funds to repay those Notes may not be available from other sources. In addition, the court might direct you to repay any amounts that you already received in respect of those Notes from the Guarantor.

The measures of insolvency for purposes of fraudulent transfer laws vary depending upon the governing law. Generally, a guarantor would be considered insolvent if:

•

the sum of its debts, including contingent liabilities, was greater than the fair saleable value of all its assets;

•

the present fair saleable value of its assets was less than the amount that would be required to pay its probable liability, including contingent liabilities, as they became absolute and mature; or

•

it could not pay its debts as they became due.

The guarantee for the Notes will contain a provision intended to limit the Guarantors’ liability to the maximum amount that they could incur without causing the incurrence of obligations under the guarantee to be a fraudulent conveyance or fraudulent transfer under U.S. federal or state law. This provision may not be effective to protect the guarantee from being voided under fraudulent transfer law.

We cannot provide assurance that an active trading market will develop for the Notes.

The 20 Notes and the 20 Notes will each constitute a new series of securities with no established trading market and there can be no assurance that the existing trading market in the 2051 Notes will be maintained. The underwriters have advised us that they intend to make a market in the Notes as permitted by applicable laws and regulations; however, the underwriters are not obligated to make a market in the Notes, and they may discontinue their market-making activities at any time without notice. Therefore, we cannot assure you that an active market for the Notes will develop or, if developed, that it will continue. We cannot assure you that the market, if any, for the Notes will be free from disruptions that may adversely affect the

price at which you may sell the Notes. Future trading prices of the Notes will also depend on many other factors, including, among other things, prevailing interest rates, the market for similar securities, our financial performance and other factors. Generally, the liquidity of, and trading market for, the Notes may also be materially and adversely affected by declines in the market for similar debt securities. Such a decline may materially and adversely affect that liquidity and trading independent of our financial performance and prospects.

USE OF PROCEEDS

We estimate that the net proceeds of this offering of the Notes, after deducting underwriting discounts and commissions and the estimated expenses of this offering (and excluding accrued and unpaid interest on the New 2051 Notes), will be approximately US$ . We intend to use the net proceeds to reduce existing indebtedness of the Corporation or its subsidiaries, partially fund capital projects and, if applicable, for other general corporate purposes of the Corporation and its affiliates. The Corporation may invest funds that it does not immediately require in short-term marketable debt securities.

We may have outstanding existing indebtedness owing to certain of the underwriters and affiliates of the underwriters, a portion of which we may repay with the net proceeds of this offering. As a result, one or more of the underwriters or their affiliates may receive a portion of the net proceeds of this offering. See “Underwriting” in this prospectus supplement.

TABLE OF CONTENTS

DESCRIPTION OF THE NOTES AND THE GUARANTEES

The following description of the terms of the Notes and the guarantees supplements, and to the extent inconsistent therewith supersedes, the description of the general terms and provisions of debt securities and guarantees under the heading “Description of Debt Securities and Guarantees” in the accompanying prospectus, and should be read in conjunction with that description. In this section, the terms “Corporation”, “Enbridge”, “we”, “us” or “our” refer only to Enbridge Inc. and not to its subsidiaries and the term “Guarantors” refers to SEP and EEP.

The Notes of each series will be issued under an indenture (as amended and supplemented from time to time, the “Indenture”), dated as of February 25, 2005, among the Corporation, the Guarantors and Deutsche Bank Trust Company Americas, as Trustee. The Notes will not be offered or sold to persons in Canada pursuant to this prospectus supplement. The Trustee will initially serve as paying agent for the Notes. The following summary of certain provisions of the Indenture and the Notes does not purport to be complete and is qualified in its entirety by reference to the actual provisions of the Indenture.

General

The Trustee under the Indenture is referred to in this section as the “Trustee”, which term shall include, unless the context otherwise requires, its successors and assigns. Capitalized terms used but not defined in this section shall have the meanings given to them in the Indenture.

The Notes will be direct, unsecured and unsubordinated obligations of the Corporation, issued under the Indenture and will rank equally with all other existing and future unsecured and unsubordinated indebtedness of the Corporation other than preferred claims imposed by statute. The Notes will be guaranteed by both Guarantors. See “— Guarantees” in this prospectus supplement. In addition, our business operations are conducted substantially through our subsidiaries and through partnerships and joint ventures. The Notes will be structurally subordinated to all existing and future liabilities of our subsidiaries other than the Guarantors. As of June 30, 2021, the long-term debt (excluding current portion, as well as guarantees and intercompany obligations between the Corporation and its subsidiaries) of the Corporation’s subsidiaries other than the Guarantors totaled approximately $25,170 million. At June 30, 2021, as determined under U.S. GAAP, the Corporation’s total consolidated long-term debt and long-term debt due within one year was, in aggregate principal amount, approximately $66,829 million (excluding the Notes and the Corporation’s proportionate share of non-recourse debt of joint ventures), none of which was secured debt. There are no terms of the Indenture that limit the ability of the Corporation or its subsidiaries, partnerships or joint ventures to issue preferred stock or incur additional indebtedness, including in the case of the Corporation and its subsidiaries, partnerships and joint ventures, indebtedness that ranks, either effectively or by contract, senior to the Notes. See “— Covenants” in this prospectus supplement. Nonetheless, we do not expect either Guarantor to issue any preferred stock or any additional debt after the date of this prospectus supplement.

The Notes may be redeemed by the Corporation prior to maturity as described below under “Redemption — Optional Redemption”.

The Notes will be subject to the provisions of the Indenture relating to Defeasance and Covenant Defeasance as described under the heading “— Defeasance” in this prospectus supplement.

The provisions of the Indenture relating to the payment of additional amounts in respect of Canadian withholding taxes in certain circumstances and relating to the redemption of the Notes in the event of specified changes in Canadian withholding tax law on or after the date of this prospectus supplement will apply to the Notes. See “— Payment of Additional Amounts” and “— Redemption — Tax Redemption” in this prospectus supplement.

The Notes will not be entitled to the benefit of any sinking fund, will not be convertible into other securities of the Corporation in lieu of payment of principal and will not be listed on any automated quotation system, and we do not intend to apply for listing of the Notes on any securities exchange.

The Notes will be denominated in U.S. dollars, and payments of principal of, and premium, if any, and interest on, the Notes will be made in U.S. dollars in the manner and on terms set out in the Indenture.

S-10

TABLE OF CONTENTS

Payments of principal of, and premium, if any, and interest on, the Notes will be made by the Corporation through the Trustee to the Depositary. See “— Book-Entry System” in this prospectus supplement.

For purposes of the Notes, “Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in the City of New York and in the applicable Place of Payment, if other than the City of New York, are authorized or obligated by law or executive order to close. The initial Place of Payment for the Notes will be the Trustee’s corporate trust office in The City of New York.

The Corporation may, at any time, and from time to time in accordance with the terms of the Indenture, issue additional Notes of any series in unlimited amounts having the same terms as the 20 Notes, 20 Notes or 2051 Notes, as the case may be, and such additional Notes will, together with the then 20 Notes, 20 Notes or 2051 Notes, as the case may be and any notes which may be issued in exchange or substitution therefor, constitute a single series of notes under the Indenture.

Principal and Interest

The 20 Notes will be issued as a series of debt securities under the Indenture in an aggregate principal amount of US$ million. The 20 Notes will mature on , 20 and will bear interest at a rate of % per annum, payable semi-annually in arrears on and of each year, commencing , 2021 (each, a “20 Interest Payment Date”), to the persons in whose names the 20 Notes are registered at the close of business on the preceding or , respectively. Interest on the 20 Notes will be computed on the basis of a 360-day year of twelve 30-day months.

The New 2051 Notes will be issued as a series of debt securities under the Indenture in an aggregate principal amount of US$ million, which, together with the Existing 2051 Notes will result in an aggregate principal amount of US$ million 2051 Notes outstanding. The New 2051 Notes will mature on August 1, 2051 and will bear interest at a rate of 3.400% per annum, payable semi-annually in arrears on February 1 and August 1 of each year, commencing February 1, 2022 (each, a “2051 Interest Payment Date” and, together with each 20 Interest Payment Date and 20 Interest Payment Date, the “Interest Payment Dates”), to the persons in whose names the New 2051 Notes are registered at the close of business on the preceding January 15 or July 15, respectively. Interest on the New 2051 Notes will be computed on the basis of a 360-day year of twelve 30-day months.

Interest payments for the 20 Notes will include accrued interest from and including the date of issue or from and including the last date in respect of which interest has been paid, as the case may be, to, but excluding, the 20 Interest Payment Date, or the date of maturity, as the case may be. Interest payments for the 20 Notes will include accrued interest from and including the date of issue or from and including the last date in respect of which interest has been paid, as the case may be, to, but excluding, the 20 Interest Payment Date, or the date of maturity, as the case may be. Interest payments for the New 2051 Notes will include accrued interest from and including June 28, 2021 or from and including the last date in respect of which interest has been paid, as the case may be, to, but excluding, the 2051 Interest Payment Date, or the date of maturity, as the case may be. If any Interest Payment Date or the applicable maturity date of the Notes falls on a day that is not a Business Day, the related payment of principal of, premium, if any, or interest thereon will be postponed to the next succeeding Business Day, and no interest on that payment will accrue for the period from and after that Interest Payment Date or the applicable maturity date, as the case may be.

Guarantees

Each of the Guarantors fully, unconditionally, irrevocably, absolutely and jointly and severally guarantees to each Noteholder of each series the due and punctual payment of the principal of, and premium, if any, and

S-11

TABLE OF CONTENTS

interest on the Notes and all other amounts due and payable by the Corporation under the Indenture and the Notes, when and as such principal, premium, if any, interest and other amounts shall become due and payable, whether at the stated maturity or by declaration or acceleration, call for redemption or otherwise, subject to limitations on amount so that such guarantee does not constitute a fraudulent conveyance or fraudulent transfer under federal or state law, as set forth in the Indenture. The guarantees of the Notes will be general, unsecured, senior obligations of each of the Guarantors and will rank equally with all other existing and future unsecured and unsubordinated indebtedness of that Guarantor, other than preferred claims imposed by statute.

Pursuant to the Indenture, the guarantees of either Guarantor will be unconditionally released and discharged automatically upon the occurrence of any of the following events:

•

any direct or indirect sale, exchange or transfer, whether by way of merger, sale or transfer of equity interests or otherwise, to any person that is not an affiliate of the Corporation, of any of the Corporation’s direct or indirect limited partnership or other equity interests in that Guarantor as a result of which that Guarantor ceases to be a consolidated subsidiary of the Corporation;

•

the merger of that Guarantor into the Corporation or the other Guarantor or the liquidation and dissolution of that Guarantor;

•

with respect to any series of the Notes, the repayment in full or discharge or defeasance of Notes of that series as contemplated by the Indenture;

•

with respect to EEP, the repayment in full or discharge or defeasance of each series of debt securities of EEP outstanding as of January 22, 2019, all of which are guaranteed by the Corporation pursuant to the Seventeenth Supplemental Indenture, dated as of January 22, 2019, among EEP, the Corporation and U.S. Bank National Association, as trustee; or

•

with respect to SEP, the repayment in full or discharge or defeasance of each series of debt securities of SEP outstanding as of January 22, 2019, all of which are guaranteed by the Corporation pursuant to the Eighth Supplemental Indenture, dated as of January 22, 2019, among SEP, the Corporation and Wells Fargo Bank, National Association, as trustee.

The Trustee

Deutsche Bank Trust Company Americas (the “Trustee”) is the Trustee under the Indenture governing the Notes. The Trustee is an affiliate of Deutsche Bank Securities Inc., an underwriter of the Notes. Under the Trust Indenture Act of 1939, as amended, due to this affiliation, if a default occurred on the Notes within one year of issuance, Deutsche Bank Trust Company Americas may be required to resign as Trustee within 90 days of ascertaining the default unless the default (exclusive of any period of grace or requirement of notice) is cured, duly waived or otherwise eliminated. An affiliate of the Trustee is a lender under certain of the credit facilities of Enbridge and its subsidiary, Enbridge (U.S.) Inc., described under “Underwriting” in this prospectus supplement, and affiliates of the Trustee may have further commercial banking, advisory and other relationships with Enbridge and its subsidiaries.

Redemption

Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes of the series or portions of the series of Notes called for redemption.

Notice of redemption of Notes of any series will be given once not more than 60 nor less than 10 days prior to the date fixed for redemption and will specify the date fixed for redemption.

securities regulatory authority in each of the Provinces of Canada within 15 days after the same are so required to be filed with such securities commissions or securities regulatory authorities.

Covenants

The Indenture contains promises by the Corporation, called “covenants” for the benefit of the Noteholders. The Corporation will make the covenants described under the headings “— Limitation on Security Interests” and “— Other Indenture Covenants” for the Noteholders.

Limitation on Security Interests

The Corporation agrees in the Indenture, for the benefit of the Noteholders, that it will not create, assume or otherwise have outstanding any Security Interest on its assets securing any Indebtedness unless the obligations of the Corporation in respect of the Notes then outstanding shall be secured equally and ratably therewith.

This covenant has significant exceptions which allow the Corporation to incur or allow to exist over its properties and assets Permitted Encumbrances (as defined in the Indenture), which include, among other things:

In addition, the Indenture permits the Corporation to incur or allow to exist any other Security Interest or Security Interests if the amount of Indebtedness secured under the Security Interest or Security Interests does not exceed 5% of the Corporation’s Consolidated Net Tangible Assets.

The Indenture covenant restricting Security Interests will not restrict the Corporation’s ability to sell its property and other assets and will not restrict any subsidiary of the Corporation from creating, assuming or otherwise having outstanding any Security Interests on its assets.

Other Indenture Covenants

The Corporation will covenant with respect to the Notes to (1) duly and punctually pay amounts due on the Notes; (2) maintain an office or agency where the Notes may be presented or surrendered for payment, where the Notes may be surrendered for registration of transfer or exchange and where notices and demands to the Corporation may be served; (3) deliver to the Trustee, within 120 days after the end of each fiscal year, a certificate stating whether or not the Corporation is in default under the Indenture; (4) pay before delinquency, taxes, assessments and governmental charges and lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Corporation, subject to the right of the Corporation to contest the validity of a charge, assessment or claim in good faith; and (5) maintain and keep in good condition properties used or useful in the conduct of its business and make necessary repairs and improvements as in the judgment of the Corporation are necessary to carry on the Corporation’s business; provided, that the Corporation may discontinue operating or maintaining any of its properties if, in the judgment of the Corporation, the discontinuance is desirable in the conduct of the Corporation’s business and not disadvantageous in any material respect to the Noteholders.

Subject to the provision described under the heading “— Mergers, Consolidations and Sales of Assets” below, the Corporation will also covenant that it will do all things necessary to preserve and keep in full force and effect its existence, rights and franchises; provided that the Corporation is not required to preserve any right or franchise if the board of directors of the Corporation determines that preservation of the right or franchise is no longer desirable in the conduct of the business of the Corporation and that its loss is not disadvantageous in any material respect to the Noteholders.

Waiver of Covenants

The Corporation may omit in any particular instance to comply with any term, provision or condition in any covenant in respect of a series of the Notes, if before the time for such compliance the holders of a majority of the principal amount of the outstanding notes of that series of the Notes waive compliance with the applicable term, provision or condition.

Mergers, Consolidations and Sales of Assets

The Corporation may not consolidate or amalgamate with or merge into, or enter into any statutory arrangement for such purpose with, any other person or convey, transfer or lease its properties and assets substantially as an entirety to any person, unless, among other requirements:

(a)

the successor to the consolidation, amalgamation, merger or arrangement is a corporation,

S-16

TABLE OF CONTENTS

partnership or trust organized under the laws of Canada, or any Province or Territory thereof, the United States of America, or any State thereof or the District of Columbia, and expressly assumes the obligation to pay the principal of and any premium and interest on all of the Notes and perform or observe the covenants and obligations contained in the Indenture;

(b)

immediately after giving effect to the transaction, no event of default, or event which, after notice or lapse of time or both, would become an event of default, will have happened and be continuing; and

(c)

if, as a result of any such consolidation, amalgamation, merger or arrangement, properties or assets of the Corporation would become subject to a mortgage, pledge, lien, security interest or other encumbrance which would not be permitted by the Indenture, the Corporation or such successor, as the case may be, shall take such steps as shall be necessary effectively to secure the Notes equally and ratably with (or prior to) all indebtedness secured thereby.

Upon any consolidation, amalgamation, merger or arrangement of the Corporation or conveyance, transfer or lease of properties and assets of the Corporation substantially as an entirety, the successor to the Corporation will succeed to every right and power of the Corporation under the Indenture, and, except in the case of a lease, the Corporation will be relieved of all obligations and covenants under the Indenture and the Notes.

Payment of Additional Amounts

The Corporation will, subject to the exceptions and limitations set forth below, pay to any Noteholders of any series of Notes who is a non-resident of Canada under the Income Tax Act (Canada) (“Tax Act”) such additional amounts as may be necessary so that every net payment on the Notes held by such Noteholder, after deduction or withholding by the Corporation or any of its paying agents for or on account of any present or future tax, assessment or other governmental charge (including penalties, interest and other liabilities related thereto) imposed by the government of Canada (or any political subdivision or taxing authority thereof or therein) (collectively, “Canadian Taxes”) upon or as a result of such payment, will not be less than the amount provided in those Notes to be then due and payable (and the Corporation will remit the full amount withheld to the relevant authority in accordance with applicable law). However, the Corporation will not be required to make any payment of additional amounts:

(a)

to any person in respect of whom such taxes are required to be withheld or deducted as a result of such person or any other person that has a beneficial interest in respect of any payment under those Notes (i) not dealing at arm’s length with the Corporation (within the meaning of the Tax Act), (ii) being a “specified shareholder” (as defined in subsection 18(5) of the Tax Act) of the Corporation, or (iii) not dealing at arm’s length (for the purposes of the Tax Act) with such a “specified shareholder”;

(b)

to any person by reason of such person being connected with Canada (otherwise than merely by holding or ownership of those Notes or receiving any payments or exercising any rights thereunder), including without limitation a non-resident insurer who carries on an insurance business in Canada and in a country other than Canada;

(c)

for or on account of any tax, assessment or other governmental charge which would not have been so imposed but for: (i) the presentation by the holder of those Notes on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; or (ii) the holder’s failure to comply with any certification, identification, information, documentation or other reporting requirements if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from or a reduction in the rate of deduction or withholding of, any such taxes, assessment or charge;

(d)

for or on account of any estate, inheritance, gift, sales, transfer, personal property tax or any similar tax, assessment or other governmental charge;

(e)

for or on account of any tax, assessment or other governmental charge required to be withheld by

S-17

TABLE OF CONTENTS

any paying agent from any payment to a person on those Notes if such payment can be made to such person without such withholding by at least one other paying agent the identity of which is provided to such person;

(f)

for or on account of any tax, assessment or other governmental charge which is payable otherwise than by withholding from a payment on those Notes;

(g)

any withholding or deduction imposed pursuant to: (i) Sections 1471 to 1474 of the U.S. Internal Revenue Code of 1986, as amended (“FATCA”), or any successor version thereof, or any similar legislation imposed by any other governmental authority, (ii) any treaty, law, regulation or other official guidance enacted by Canada implementing FATCA or an intergovernmental agreement with respect to FATCA or any similar legislation imposed by any other governmental authority, or (iii) any agreement between the Corporation or the Guarantors and the United States or any authority thereof implementing FATCA; or

(h)

for any combination of items (a), (b), (c), (d), (e), (f) and (g);

nor will additional amounts be paid with respect to any payment on those Notes to a Noteholder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of Canada (or any political subdivision thereof) to be included in the income for Canadian federal income tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to payment of the additional amounts had such beneficiary, settlor, member or beneficial owner been the Noteholder of such Notes.

The Corporation will furnish to the Noteholders, within 30 days after the date of the payment of any Canadian Taxes is due under applicable law, certified copies of tax receipts or other documents evidencing such payment.

Wherever in the Notes or Indenture there is mentioned, in any context, the payment of principal (and premium, if any), interest or any other amount payable under or with respect to the Notes, such mention shall be deemed to include mention of the payment of additional amounts to the extent that, in such context additional amounts are, were or would be payable in respect thereof.

Events of Default

The following events are defined in the Indenture as “Events of Default” with respect to each series of the Notes:

(a)

the failure of the Corporation to pay when due the principal of or premium (if any) on any notes of such series of the Notes;

(b)

the failure of the Corporation, continuing for 30 days, to pay any interest due on any notes of such series of the Notes;

(c)

the breach or violation of any covenant or condition (other than as referred to in (a) and (b) above), which continues for a period of 60 days after notice from the Trustee or from holders of at least 25% of the principal amount of all outstanding notes of such series of the Notes, if such covenant or condition applies to such series of the Notes;

(d)

default in payment at maturity, including any applicable grace period, or default in the performance or observance of any other covenant, term, agreement or condition with respect to any single item of Indebtedness in an amount in excess of 5% of Consolidated Shareholders’ Equity or with respect to more than two items of Indebtedness in an aggregate amount in excess of 10% of Consolidated Shareholders’ Equity and, if such Indebtedness has not already matured in accordance with its terms, such Indebtedness has been accelerated, if such Indebtedness has not been discharged or such acceleration shall not have been rescinded or annulled within a period of 10 days after there shall have been given, by registered or certified mail, to the Corporation by the Trustee or to the Corporation and the Trustee by the holders of at least 25% of the principal amount of the outstanding notes of such series of the Notes a written notice specifying the default and requiring the Corporation to cause such Indebtedness to be discharged or cause such acceleration to be

S-18

TABLE OF CONTENTS

rescinded or annulled, provided that if the Indebtedness is discharged or the applicable default under the Indebtedness is waived by the persons entitled to do so, then the Event of Default under the Indenture will be deemed waived; or

(e)

certain events of bankruptcy, insolvency or reorganization involving the Corporation.

If an Event of Default occurs and is continuing with respect to any series of the Notes, then in every such case the Trustee or the holders of at least 25% of the aggregate principal amount of the outstanding notes of such affected series of the Notes may declare the entire principal amount of such series of the Notes and all interest thereon to be immediately due and payable. However, at any time after a declaration of acceleration with respect to any series of the Notes has been made, but before a judgment or decree for payment of the money due has been obtained, the holders of a majority in principal amount of the outstanding notes of such series of the Notes, by written notice to the Corporation and the Trustee under certain circumstances (which include payment or deposit with the Trustee of outstanding principal, premium and interest), may rescind and annul such acceleration.

The Indenture provides that, subject to the duty of the Trustee during default to act with the required standard of care, the Trustee shall be under no obligation to exercise any of its rights and powers under the Indenture at the request or direction of any of the Noteholders, unless such Noteholders shall have offered to the Trustee reasonable indemnity. Subject to such provisions for indemnification of the Trustee and certain other limitations set forth in the Indenture, the holders of a majority in principal amount of the outstanding notes of a series of the Notes affected by an Event of Default shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the notes of such series of the Notes.

No Noteholder of any series of Notes will have any right to institute any proceeding with respect to the Indenture (including the guarantees thereof), or for the appointment of a receiver or a Trustee, or for any other remedy thereunder, unless (a) such Noteholder has previously given to the Trustee written notice of a continuing Event of Default with respect to the notes of such series of the Notes, (b) the holders of at least 25% of the aggregate principal amount of the outstanding notes of such series of the Notes have made written request, and such Noteholder or Noteholders have offered reasonable indemnity, to the Trustee to institute such proceeding as Trustee, and (c) the Trustee has failed to institute such proceeding, and has not received from the holders of a majority in aggregate principal amount of the outstanding notes of such series of the Notes a direction inconsistent with such request, within 60 days after such notice, request and offer. However, such limitations do not apply to a suit instituted by a Noteholder for the enforcement of payment of the principal of or any premium or interest on such Notes on or after the applicable due date specified in such Notes.

Modification and Waiver

Modifications and amendments of the Indenture may be made by the Corporation and the Trustee with the consent of the holders of a majority of the principal amount of the outstanding debt securities of each series issued under the Indenture (including each series of the Notes) affected by such modification or amendment; provided, however, that no such modification or amendment may, without the consent of the holder of each outstanding debt security of such affected series: (1) change the stated maturity of the principal of, or any installment of interest, if any, on any debt security; (2) reduce the principal amount of, or the premium, if any, or the rate of interest, if any, on any debt security; (3) change the Place of Payment; (4) change the currency or currency unit of payment of principal of (or premium, if any) or interest, if any, on any debt security; (5) impair the right to institute suit for the enforcement of any payment on or with respect to any debt security; (6) adversely affect any right to convert or exchange any debt security; (7) reduce the percentage of principal amount of outstanding debt securities of such series, the consent of the holders of which is required for modification or amendment of the Indenture or for waiver of compliance with certain provisions of the Indenture or for waiver of certain defaults; (8) modify the provisions of the Indenture relating to subordination in a manner that adversely affects the rights of the holders of debt securities; or (9) modify any provisions of the Indenture relating to the modification and amendment of the Indenture or the waiver of past defaults or covenants except as otherwise specified in the Indenture.

S-19

TABLE OF CONTENTS

The holders of a majority of the principal amount of any series of the Notes may on behalf of the Noteholders of that series of the Notes waive, insofar as that series of the Notes is concerned, compliance by the Corporation with certain restrictive provisions of the Indenture, including the covenants and events of default. The holders of a majority in principal amount of any series of the Notes may waive any past default under the Indenture with respect to that series of the Notes, except a default in the payment of the principal of (or premium, if any) and interest, if any, on that series of the Notes or in respect of a provision which under the Indenture cannot be modified or amended without the consent of the holder of each outstanding note of that series of Notes. The Indenture or the Notes may be amended or supplemented, without the consent of any holder of debt securities, in order, among other purposes, to cure any ambiguity or inconsistency or to make any change that does not have an adverse effect on the rights of any holder of the debt securities.

Defeasance

The Indenture provides that, at its option, the Corporation will be discharged from any and all obligations in respect of the outstanding notes of any series of the Notes upon irrevocable deposit with the Trustee, in trust, of money and/or United States government securities which will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants to pay the principal of and premium, if any, and each installment of interest, if any, on the outstanding notes of such series of Notes (“Defeasance”) (except with respect to the authentication, transfer, exchange or replacement of Notes or the maintenance of a Place of Payment and certain other obligations set forth in the Indenture). Such trust may only be established if among other things (1) the Corporation has delivered to the Trustee an opinion of counsel in the United States stating that (a) the Corporation has received from, or there has been published by, the Internal Revenue Service a ruling, or (b) since the date of execution of the Indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that the holders of the outstanding notes of such series of the Notes will not recognize income, gain or loss for United States federal income tax purposes as a result of such Defeasance and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Defeasance had not occurred; (2) the Corporation has delivered to the Trustee an opinion of counsel in Canada or a ruling from the Canada Revenue Agency (“CRA”) to the effect that the holders of the outstanding notes of such series of the Notes will not recognize income, gain or loss for Canadian federal, provincial or territorial income or other tax purposes as a result of such Defeasance and will be subject to Canadian federal or provincial income and other tax on the same amounts, in the same manner and at the same times as would have been the case had such Defeasance not occurred (and for the purposes of such opinion, such Canadian counsel shall assume that holders of the outstanding notes of such series of the Notes include holders who are not resident in Canada); (3) no Event of Default or event that, with the passing of time or the giving of notice, or both, shall constitute an Event of Default shall have occurred and be continuing on the date of such deposit; (4) the Corporation is not an “insolvent person” within the meaning of the Bankruptcy and Insolvency Act (Canada); (5) the Corporation has delivered to the Trustee an opinion of counsel to the effect that such deposit shall not cause the Trustee or the trust so created to be subject to the United States Investment Company Act of 1940, as amended; and (6) other customary conditions precedent are satisfied. The Corporation may exercise its Defeasance option notwithstanding its prior exercise of its Covenant Defeasance option described in the following paragraph if the Corporation meets the conditions described in the preceding sentence at the time the Corporation exercises the Defeasance option.

The Indenture provides that, at its option, the Corporation may omit to comply with certain covenants, including certain of the covenants described above under the heading “Covenants”, and such omission shall not be deemed to be an Event of Default under the Indenture and the outstanding Notes upon irrevocable deposit with the Trustee, in trust, of money and/or United States government securities which will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants to pay the principal of and premium, if any, and each installment of interest, if any, on the outstanding Notes (“Covenant Defeasance”). If the Corporation exercises its Covenant Defeasance option, the obligations under the Indenture other than with respect to such covenants and the Events of Default other than with respect to such covenants shall remain in full force and effect. Such trust may only be established if, among other things, (1) the Corporation has delivered to the Trustee an opinion of counsel in the United States to the effect that the holders of the outstanding Notes will not recognize income, gain or loss for United States federal income tax purposes as a result of such Covenant Defeasance and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been

S-20

TABLE OF CONTENTS

the case if such Covenant Defeasance had not occurred; (2) the Corporation has delivered to the Trustee an opinion of counsel in Canada or a ruling from the CRA to the effect that the holders of such outstanding Notes will not recognize income, gain or loss for Canadian federal, provincial or territorial income or other tax purposes as a result of such Covenant Defeasance and will be subject to Canadian federal or provincial income and other tax on the same amounts, in the same manner and at the same times as would have been the case had such Covenant Defeasance not occurred (and for the purposes of such opinion, such Canadian counsel shall assume that holders of the outstanding Notes include holders who are not resident in Canada); (3) no Event of Default or event that, with the passing of time or the giving of notice, or both, shall constitute an Event of Default shall have occurred and be continuing on the date of such deposit; (4) the Corporation is not an “insolvent person” within the meaning of the Bankruptcy and Insolvency Act (Canada); (5) the Corporation has delivered to the Trustee an opinion of counsel to the effect that such deposit shall not cause the Trustee or the trust so created to be subject to the United States Investment Company Act of 1940, as amended; and (6) other customary conditions precedent are satisfied.

Book-Entry System

The Notes will be represented by fully registered global securities (the “Global Securities”) registered in the name of Cede & Co. (the nominee of The Depository Trust Company (the “Depositary”)), or such other name as may be requested by an authorized representative of the Depositary. The authorized minimum denominations of each Note will be US$2,000 and integral multiples of US$1,000 in excess thereof. Accordingly, Notes may be transferred or exchanged only through the Depositary and its participants. Except as described below, owners of beneficial interests in the Global Securities will not be entitled to receive Notes in definitive form. Account holders in the Euroclear or Clearstream clearance systems may hold beneficial interests in the Notes through the accounts that each of these systems maintains as a participant in the Depositary. So long as the Depositary for a Global Security or its nominee is the registered owner of the Global Security, such Depositary or such nominee, as the case may be, will be considered the sole owner or holder of the Notes represented by the Global Security for all purposes under the Indenture. Except as provided below, owners of beneficial interests in a Global Security will not be entitled to have the Notes represented by the Global Security registered in their names, will not receive or be entitled to receive physical delivery of the Notes of such series in definitive form and will not be considered the owners or holders thereof under the Indenture. Beneficial Owners (as defined below) will not receive certificates representing their ownership interests in the Notes except in the event that use of the book-entry system for the Notes is discontinued or if there shall have occurred and be continuing an event of default under the Indenture. The Depositary will have no knowledge of the actual beneficial owners of the Notes; the Depositary’s records will reflect only the identity of the direct participants to whose accounts the Notes are credited, which may or may not be the beneficial owners. The Direct Participants and Indirect Participants (as each is defined below) will remain responsible for keeping account of their holdings on behalf of their customers.

Each person owning a beneficial interest in a Global Security must rely on the procedures of the Depositary and, if such person is not a participant, on the procedures of the participant through which such person owns its interest in order to exercise any rights of a Noteholder under the Indenture. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in certificated form. Such limits and such laws may impair the ability to transfer beneficial interests in a Global Security representing the Notes.

The Depositary

The following is based on information furnished by the Depositary: The Depositary is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the U.S. Exchange Act. The Depositary holds securities that its participants (“Participants”) deposit with the Depositary. The Depositary also facilitates the settlement among Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Participants’ accounts, thereby eliminating the need for physical movement of securities certificates. These direct Participants (“Direct Participants”) include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to the

S-21

TABLE OF CONTENTS

Depositary’s system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The rules applicable to the Depositary and its Participants are on file with the SEC.

Purchases of the Notes under the Depositary’s system must be made by or through Direct Participants, which will receive a credit for such Notes on the Depositary’s records. The ownership interest of each actual purchaser of each Note represented by a Global Security (“Beneficial Owner”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from the Depositary of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participants through which such Beneficial Owner entered into the transaction. Transfers of ownership interests in a Global Security representing Notes are to be accomplished by entries made on the books of Participants acting on behalf of Beneficial Owners. Beneficial Owners of a Global Security representing the Notes will not receive Notes in definitive form representing their ownership interests therein, except in the event that use of the book-entry system for such Notes is discontinued.

To facilitate subsequent transfers, the Global Securities representing the Notes which are deposited with the Depositary are registered in the name of the Depositary’s nominee, Cede & Co., or such other name as may be requested by an authorized representative of the Depositary. The deposit of Global Securities with the Depositary and their registration in the name of Cede & Co. or such other nominee effect no change in beneficial ownership. The Depositary has no knowledge of the actual Beneficial Owners of the Global Securities representing the Notes; the Depositary’s records reflect only the identity of the Direct Participants to whose accounts such Notes are credited, which may or may not be the Beneficial Owners. The Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by the Depositary to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial Owners of the Notes may wish to take certain steps to augment transmission to them of notices of significant events with respect to the Notes, such as redemptions, tenders, defaults and proposed amendments to the Indenture.

Any redemption notices relating to the Notes will be sent to the Depositary. If less than all of the Notes are being redeemed, the Depositary may determine by lot the amount of the interest of each Direct Participant in the Notes to be redeemed. Neither the Depositary nor its nominee will consent or vote with respect to the Notes unless authorized by a Direct Participant in accordance with the Depositary’s procedures. Under its procedures, the Depositary may send a proxy to the Corporation as soon as possible after the record date for a consent or vote. The proxy would assign the Depositary’s nominee’s consenting or voting rights to those Direct Participants to whose accounts the Notes are credited on the relevant record date.

Neither the Depositary nor Cede & Co. (nor such other nominee of the Depositary) will consent or vote with respect to the Global Securities representing the Notes. Under its usual procedures, the Depositary mails an “omnibus proxy” to the Corporation as soon as possible after the applicable record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts the Notes are credited on the applicable record date (identified in a listing attached to the omnibus proxy).

Principal, premium, if any, and interest payments on the Global Securities representing the Notes will be made to Cede & Co. (or such other nominee as may be requested by an authorized representative of the Depositary). The Depositary’s practice is to credit Direct Participants’ accounts, upon the Depositary’s receipt of funds and corresponding detail information from the Corporation or the Trustee, on the applicable payment date in accordance with their respective holdings shown on the Depositary’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name”, and will be the responsibility of such Participant and not of the Depositary, the Trustee or the Corporation, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of the Depositary) is the responsibility of the Corporation or the Trustee, disbursement of such payments to

S-22

TABLE OF CONTENTS

Direct Participants shall be the responsibility of the Depositary, and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct and Indirect Participants.

The Depositary may discontinue providing its services as securities depository with respect to the Notes at any time by giving reasonable notice to the Corporation or the Trustee. Under such circumstances, in the event that a successor securities depository is not obtained, Notes in definitive form are required to be printed and delivered to each Noteholder. No Global Security may be exchanged in whole or in part, and no transfer of a Global Security in whole or in part may be registered, in the name of any person other than the Depositary for the Global Security or its nominee unless (1) the Depositary (A) has notified the Corporation that it is unwilling or unable to continue as Depositary for the Global Security or (B) has ceased to be a clearing agency registered under the U.S. Exchange Act, or (2) there shall have occurred and be continuing an event of default under the Indenture. Except for certain restrictions set forth in the Indenture, no service charge will be made for any registration of transfer or exchange of the Notes, but the Corporation may, in certain instances, require a sum sufficient to cover any tax or other governmental charges payable in connection with these transactions. The Corporation shall not be required to: (i) issue, register the transfer of or exchange Notes during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Notes to be redeemed and ending at the close of business on the day of mailing of the relevant notice of redemption; (ii) register the transfer of or exchange the Notes, or a portion thereof, called for redemption, except the unredeemed portion of the Notes being redeemed in part; or (iii) issue, register the transfer of or exchange any Notes which have been surrendered for repayment at the option of the holder, except the portion, if any, thereof not to be so repaid.

The Corporation may decide to discontinue use of the system of book-entry transfers through the Depositary (or a successor securities depository). In that event, Notes in definitive form will be printed and delivered.

Settlement for the Notes will be made in immediately available funds. Secondary market trading in the Notes will be settled in immediately available funds.

The information in this section concerning the Depositary and the Depositary’s book-entry system has been obtained from sources that the Corporation believes to be reliable, but is subject to any changes to the arrangements between the Corporation and the Depositary and any changes to such procedures that may be instituted unilaterally by the Depositary.

Euroclear

Euroclear is incorporated under the laws of Belgium as a bank and is subject to regulation by the Belgian Banking, Finance and Insurance Commission (La Commission Bancaire, Financière et des Assurances) and the National Bank of Belgium (Banque Nationale de Belgique). Euroclear holds securities for its customers and facilitates the clearance and settlement of securities transactions among them. It does so through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates. Euroclear provides other services to its customers, including credit, custody, lending and borrowing of securities and tri-party collateral management. It interfaces with the domestic markets of several countries. Euroclear customers include banks, including central banks, securities brokers and dealers, trust companies and clearing corporations and may include certain other professional financial intermediaries. Indirect access to the Euroclear system is also available to others that clear through Euroclear customers or that have custodial relationships with Euroclear customers. All securities in Euroclear are held on a fungible basis. This means that specific certificates are not matched to specific securities clearance accounts.

The information in this section concerning Euroclear has been obtained from sources that the Corporation believes to be reliable, but is subject to any changes that may be instituted unilaterally by Euroclear.

Clearstream

Clearstream is a duly licensed bank organized as a société anonyme incorporated under the laws of Luxembourg and is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream holds securities for its customers and

S-23

TABLE OF CONTENTS

facilitates the clearance and settlement of securities transactions among them. It does so through electronic book-entry transfers between the accounts of its customers. This eliminates the need for physical movement of securities. Clearstream provides other services to its customers, including safekeeping, administration, clearance and settlement of internationally traded securities and lending and borrowing of securities. It interfaces with the domestic markets in over 30 countries through established depositary and custodial relationships. Clearstream’s customers include worldwide securities brokers and dealers, banks, trust companies and clearing corporations and may include professional financial intermediaries. Its U.S. customers are limited to securities brokers and dealers and banks. Indirect access to the Clearstream system is also available to others that clear through Clearstream customers or that have custodial relationships with its customers, such as banks, brokers, dealers and trust companies.

The information in this section concerning Clearstream has been obtained from sources that the Corporation believes to be reliable, but is subject to any changes that may be instituted unilaterally by Clearstream.

Global Clearance and Settlement Procedures

Cross market transfers between persons holding directly or indirectly through the Depositary, on the one hand, and directly or indirectly through Euroclear or Clearstream, on the other, will be effected through the Depositary in accordance with Depositary rules on behalf of the relevant European international clearing system by its U.S. depositary; however, such cross market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving Notes through the Depositary, and making or receiving payment in accordance with normal procedures for same day funds settlement applicable to the Depositary. Clearstream participants and Euroclear participants may not deliver instructions directly to their respective U.S. depositaries.

Because of time zone differences, credits of Notes received through Clearstream or Euroclear as a result of a transaction with a Depositary participant will be made during subsequent securities settlement processing and dated the business day following the Depositary settlement date. Such credits or any transactions in such Notes settled during that processing will be reported to the relevant Euroclear participants or Clearstream participants on that following business day. Cash received in Clearstream or Euroclear as a result of sales of Notes by or through a Clearstream participant or a Euroclear participant to a Depositary participant will be received with value on the Depositary settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement with the Depositary.

Although the Depositary, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of Notes among participants of the Depositary, Clearstream and Euroclear, they are under no obligation to perform or continue to perform those procedures and those procedures may be modified or discontinued at any time. Neither we nor the paying agent will have any responsibility for the performance by the Depositary, Euroclear or Clearstream or their respective direct or indirect participants of their obligations under the rules and procedures governing their operations.

TABLE OF CONTENTS

MATERIAL INCOME TAX CONSIDERATIONS

Each of the summaries under this section “Material Income Tax Considerations” is of a general nature only and is not intended to be, and should not be construed to be, legal or tax advice to any particular holder, and no representation is made with respect to the United States federal tax consequences or Canadian tax consequences to any particular holder. Accordingly, prospective purchasers are urged to consult their own tax advisors with respect to the United States federal tax consequences or Canadian tax consequences relevant to them, having regard to their particular circumstances.

Material United States Federal Income Tax Considerations

This section describes the material United States federal income tax consequences of owning and disposing of the Notes. It applies only to holders who acquire Notes of a series in the offering at the offering price for the Notes of that series and who hold their Notes as capital assets for United States federal income tax purposes. This section does not apply to members of a class of holders subject to special rules, such as a broker-dealer in securities, commodities, or currencies, a governmental organization, a trader in securities that elects to use a mark-to-market method of accounting, a bank, thrift or other financial institution, a life insurance company, a tax-exempt organization, a real estate investment trust, a regulated investment company, a foreign person or entity, an insurance company, a person that owns Notes that are a hedge or that are hedged against interest rate risks, a person that owns Notes as part of a “straddle”, “constructive sale”, “hedge” or “conversion transaction” for United States federal income tax purposes, a person that purchases or sells Notes as part of a wash sale for United States federal income tax purposes, a tax deferred or other retirement account, a person holding Notes that are a hedge or that are hedged against interest rate risks, a partnership, S corporation or other pass-through entity, or a person whose functional currency for tax purposes is not the United States dollar. This section addresses only certain U.S. federal income tax consequences and does not address any state, local or non-U.S. tax consequences, or any tax consequences arising under the Medicare contribution tax on net investment income or the estate, gift or alternative minimum tax provisions of the Internal Revenue Code of 1986, as amended (the “Code”). If Notes of a series are purchased at a price other than the offering price for the Notes of that series, the amortizable bond premium or market discount rules may also apply. Holders should consult their own tax advisors regarding this possibility.

This section is based on the Code, its legislative history, final, temporary and proposed regulations thereunder (“Treasury Regulations”), published rulings and court decisions, all as currently in effect on the date hereof. These laws are subject to change, possibly on a retroactive basis, and any such change could affect the continuing validity of this discussion. This discussion is not binding on the Internal Revenue Service (the “Service”), and we have not sought and will not seek any rulings from the Service regarding the matters discussed below. There can be no assurance that the Service will not take positions that are different from those discussed below or that a United States court will not sustain such a challenge.

All holders are urged to consult their own tax advisors concerning the consequences of owning these Notes in such holder’s particular circumstances under the Code and the laws of any other taxing jurisdiction.

This section applies only to United States holders. A United States holder is a beneficial owner of a Note that is (i) an individual who is a citizen or resident of the United States, as determined for United States federal income tax purposes, (ii) a corporation (or other entity treated as a corporation for United States federal income tax purposes) created or organized under the laws of the United States, any state thereof, or the District of Columbia, (iii) an estate whose income is includible in gross income for United States federal income tax regardless of its source or (iv) a trust, if (a) a United States court can exercise primary supervision over the trust’s administration and one or more United States persons are authorized to control all substantial decisions of the trust or (b) it has a valid election in effect under applicable Treasury Regulations to be treated as a United States person.

If a partnership (or other entity, organized within or without the United States, treated as a partnership for United States federal income tax purposes) holds Notes, the tax treatment of a partner as beneficial owner of Notes generally will depend on the status of the partner and the activities of the partnership. A partner in a partnership (or other entity treated as a partnership for United States federal income tax purposes) holding the Notes is urged to consult its tax advisor with regard to the United States federal income tax treatment of an investment in the Notes.

S-27

TABLE OF CONTENTS

Payments of Interest

Subject to the discussion in the following paragraph regarding amortizable bond premium, United States holders will be taxed on interest on the Notes as ordinary income at the time the interest is received or when it accrues, depending on the holder’s method of accounting for United States federal income tax purposes. However, the portion of the first interest payment on the New 2051 Notes that represents a return of accrued interest from June 28, 2021 to, but excluding, , 2021 that a United States holder paid as part of the purchase price of the New 2051 Notes (“Pre-Issuance Accrued Interest”) will not be treated as an interest payment for United States federal income tax purposes, and will accordingly not be includible in income.

Additionally, because the purchase price of the New 2051 Notes exceeds the principal amount of the New 2051 Notes, a United States holder may elect to treat the excess (after excluding the portion of the purchase price attributable to Pre-Issuance Accrued Interest) as amortizable bond premium. A United States holder that makes this election would reduce the amount required to be included in such holder’s income each year with respect to interest on the New 2051 Notes by the amount of amortizable bond premium allocable to that year, based on the New 2051 Notes’ yield to maturity. If a United States holder makes an election to amortize bond premium, the election would apply to all debt instruments, other than debt instruments the interest on which is excludible from gross income, that the United States holder holds at the beginning of the first taxable year to which the election applies or that such holder thereafter acquires, and the United States holder may not revoke the election without the consent of the Service.

Interest paid by us on the Notes is income from sources outside the United States for purposes of the rules regarding the foreign tax credit allowable to a United States holder and will generally be “passive category” income for purposes of computing the foreign tax credit. The rules governing the United States foreign tax credit are complex, and United States holders are urged to consult their tax advisors regarding the availability of claiming a United States foreign tax credit under their particular circumstances.

Purchase, Sale and Retirement of the Notes

A United States holder’s tax basis in a Note generally will be its cost, reduced by any bond premium that the United States holder previously amortized with respect to the Note and reduced by any Pre-Issuance Accrued Interest that was previously received by the United States holder. A United States holder will generally recognize capital gain or loss on the sale or retirement of a Note equal to the difference between the amount realized on the sale or retirement, excluding any amounts attributable to accrued but unpaid interest (which will be treated as interest payments except to the extent that such amounts are a return of Pre-Issuance Accrued Interest), and such holder’s tax basis in the Note. Capital gain of a noncorporate United States holder is generally taxed at preferential rates where the holder has a holding period greater than one year.

Gain or loss on the sale or retirement of a Note generally will be treated as United States source income or loss for United States federal income tax purposes and for purposes of computing the United States foreign tax credit allowable to a United States holder unless such gain or loss is attributable to an office or other fixed place of business outside of the United States and certain other conditions are met.

Backup Withholding and Information Reporting

For noncorporate United States holders, information reporting requirements, on Internal Revenue Service Form 1099, generally will apply to payments of principal and interest on a Note within the United States, including payments made by wire transfer from outside the United States to an account maintained in the United States, and the payment of the proceeds from the sale of a Note effected at a United States office of a broker. Additionally, backup withholding may apply to such payments if a noncorporate United States holder fails to provide an accurate taxpayer identification number, (in the case of interest payments) is notified by the Service that the holder has failed to report all interest and dividends required to be shown on the holder’s United States federal income tax returns, or, in certain circumstances, fails to comply with applicable certification requirements.

Information with Respect to Foreign Financial Assets

Owners of “specified foreign financial assets” with an aggregate value in excess of $50,000 (and in certain circumstances, a higher threshold) may be required to file an information report with respect to such assets

S-28

TABLE OF CONTENTS

with their tax returns. “Specified foreign financial assets” may include financial accounts maintained by foreign financial institutions, as well as the following, but only if they are held for investment and not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-United States persons, (ii) financial instruments and contracts that have non-United States issuers or counterparties, and (iii) interests in foreign entities. United States holders that are individuals are urged to consult their tax advisors regarding the application of this reporting requirement to their ownership of the Notes.

Material Canadian Income Tax Considerations

In the opinion of McCarthy Tétrault LLP, our Canadian counsel, the following is, as of the date hereof, a general summary of the principal Canadian federal income tax considerations under the Tax Act applicable to a purchaser of Notes as beneficial owner pursuant to the prospectus and this prospectus supplement who, at all relevant times, for purposes of the Tax Act and any applicable tax treaty (i) is not resident or deemed to be resident in Canada, (ii) deals at arm’s length with and is not affiliated with the Corporation, any of its affiliates or the underwriters; (iii) deals at arm’s length with any transferee who is resident or deemed to be resident in Canada and to whom the purchaser assigns or otherwise transfers the Note; (iv) is not a “specified shareholder” (as defined in subsection 18(5) of the Tax Act) of the Corporation or a person that does not deal at arm’s length with a specified shareholder of the Corporation and (v) does not use or hold and is not deemed to use or hold a Note in carrying on business in Canada (a “Non-Resident Holder”). This summary is based on the current provisions of the Tax Act and the regulations thereunder, proposed amendments to the Tax Act and the regulations thereunder publicly announced prior to the date of this prospectus supplement (the “Proposed Amendments”) and counsel’s understanding of the current published administrative practices of the CRA in effect as of the date hereof. This summary is not exhaustive of all possible Canadian federal income tax considerations applicable to a Non-Resident Holder and does not anticipate any changes in law or administrative practice, nor does it take into account provincial, territorial or foreign tax considerations, which may differ significantly from those discussed herein. There can be no assurance that the Proposed Amendments will be enacted as proposed or at all. Special rules, which are not discussed below, may apply to a Non-Resident Holder that is an insurer which carries on an insurance business in Canada and elsewhere. This summary assumes that no amount paid or payable as, or on account or in lieu of payment of, interest (including any amounts deemed to be interest) will be in respect of a debt or other obligation to pay an amount to a person who does not deal at arm’s length with the Corporation for purposes of the Tax Act.

This summary is of a general nature only and is not, and is not intended to be, and should not be construed to be, legal or tax advice to any particular Non-Resident Holder and no representation with respect to the income tax consequences to any particular Non-Resident Holder is made. Prospective purchasers of Notes should consult their own tax advisors with respect to the tax consequences of acquiring, holding and disposing of Notes having regard to their own particular circumstances.

Under the Tax Act, the payment of interest, principal or premium, if any, to a Non-Resident Holder of a Note by the Corporation will be exempt from Canadian non-resident withholding tax. No other taxes on income or capital gains will be payable under the Tax Act in respect of the acquisition, holding, redemption or disposition of a Note by a Non-Resident Holder, or the receipt of interest, principal or premium thereon by a Non-Resident Holder solely as a consequence of such acquisition, holding, redemption or disposition of a Note.

UNDERWRITING

Deutsche Bank Securities Inc., Mizuho Securities USA LLC, MUFG Securities Americas Inc. and Wells Fargo Securities, LLC are acting as representatives of the underwriters named below.

Subject to the terms and conditions stated in the underwriting agreement, dated the date of this prospectus supplement, each underwriter named below has severally agreed to purchase, and we have agreed to sell to that underwriter, the principal amount of Notes set forth opposite such underwriter’s name.

The underwriting agreement provides that the obligations of the underwriters to purchase the Notes included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the Notes if they purchase any of the Notes. The underwriters reserve the right to cancel, reject or modify an order of Notes in whole or in part.

The underwriters propose to offer the Notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement and may offer the Notes to dealers at the public offering price less a concession not to exceed % of the principal amount of the 20 Notes, % of the principal amount of the 20 Notes and % of the principal amount of the New 2051 Notes. The underwriters may allow, and dealers may reallow, a concession not to exceed % of the principal amount of the 20 Notes, % of the principal amount of the 20 Notes and % of the principal amount of the New 2051 Notes. After the initial offering of the Notes to the public, the representatives may change the public offering price, concessions and other selling terms.

In connection with the offering, each of Deutsche Bank Securities Inc., Mizuho Securities USA LLC, MUFG Securities Americas Inc. and Wells Fargo Securities, LLC, on behalf of the underwriters, may purchase and sell Notes in the open market. These transactions may include over-allotment, syndicate covering transactions and stabilizing transactions. Over-allotment involves syndicate sales of Notes in excess of the principal amount of Notes to be purchased by the underwriters in the offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of Notes made for the purpose of preventing or retarding a decline in the market price of the Notes while the offering is in progress.

Any of these activities may have the effect of preventing or retarding a decline in the market price of the Notes. They may also cause the price of the Notes to be higher than the price that otherwise would exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time. There will be no obligation on Deutsche Bank Securities Inc., Mizuho Securities USA LLC, MUFG Securities Americas Inc. and Wells Fargo Securities, LLC, to engage in these activities.

The 20 Notes and the 20 Notes are new issues of securities with no established trading market. The Existing 2051 Notes are not listed on any automated dealer quotation system or securities exchange and the Notes will not be listed on any automated dealer quotation system, and we do not intend to apply for listing of the Notes on any securities exchange. We have been advised that the underwriters currently intend to make a market in each series of the Notes. However, they are not obligated to do so and they may discontinue any market-making activities with respect to the Notes at any time without notice. No assurance can be given as to the liquidity of the trading market for the Notes or that an active public market for the Notes will develop. If an active public trading market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected.

The Notes are not being offered in and may not be sold to any persons in Canada.

The underwriters or their affiliates perform and have performed commercial banking, investment banking and advisory services for us from time to time for which they receive and have received customary fees and expenses. The underwriters may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business. In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. These investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of these securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in these securities and instruments.

As at September 24, 2021, the Corporation had approximately $732 million and US$1,478 million of outstanding unsecured indebtedness under our unsecured credit facilities. In addition, as at September 24, 2021, approximately $5,820 million and US$2,675 million of our unsecured credit facilities were used as a backstop to support outstanding commercial paper balances. The Corporation is in compliance with the terms of its unsecured credit facilities and there have been no waivers of breaches thereunder. There has been no materially adverse change to the financial position of the Corporation since the indebtedness was incurred. The Corporation may use the net proceeds of the offering to pay down short-term debt, and, as a consequence, net proceeds from the offering may be paid to one or more lenders who are affiliated with the underwriters.

Certain of the underwriters are affiliates of banks that are currently lenders to us (the “Lenders”) under credit facilities extended to the Corporation and certain of its subsidiaries (the “Enbridge Credit Facilities”) and, as a result, under applicable Canadian securities legislation, we may be considered to be a connected issuer to those underwriters. We are in compliance with the terms of the Enbridge Credit Facilities and none of the Lenders was involved in the decision to offer the Notes or in the determination of the terms of the distribution of the Notes. The Trustee is an affiliate of Deutsche Bank Securities Inc., an underwriter of the Notes.

If any of the underwriters or their affiliates has a lending relationship with us or our affiliates, certain of those underwriters or their affiliates routinely hedge, certain other of those underwriters or their affiliates have hedged and are likely in the future to hedge, and certain other of those underwriters of their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge that exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our affiliates’ securities, including potentially the Notes offered hereby. Any of these credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby.

S-32

TABLE OF CONTENTS

A prospectus supplement in electronic format may be made available on the websites maintained by one or more of the underwriters.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the U.S. Securities Act, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

We expect that delivery of the Notes will be made against payment therefor on or about the date specified on the cover page of this prospectus supplement, which will be the third business day following the date of pricing of the Notes (this settlement cycle being herein referred to as “T+3”). Under Rule 15c6-1 of the U.S. Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes on the date of this prospectus supplement will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to make such trades should consult their own advisor.

Notice to Prospective Investors in the European Economic Area

The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

We may from time to time offer our debt securities (which may be guaranteed by our wholly owned subsidiaries, Spectra Energy Partners, LP (“SEP”) and Enbridge Energy Partners, L.P. (“EEP”)), common shares and cumulative redeemable preference shares (the “preference shares” and, together with our debt securities, the subsidiary guarantees of our debt securities (the “guarantees”) and our common shares, the “Securities”). We may offer the Securities separately or together, in separate series or classes and in amounts, at prices and on terms described in one or more supplements to this prospectus (the “Prospectus”).

The specific variable terms of any offering of Securities will be set forth in one or more supplements to this Prospectus (a “Prospectus Supplement”) including, where applicable: (i) in the case of common shares or preference shares, the number of shares offered and the offering price; and (ii) in the case of debt securities, the designation, any limit on the aggregate principal amount, the currency or currency unit, the maturity, the offering price, whether payment on the debt securities will be senior or subordinated to our other liabilities and obligations, whether the debt securities will bear interest, the interest rate or method of determining the interest rate, any terms of redemption, any conversion or exchange rights, whether the debt securities will be guaranteed and any other specific terms of the debt securities. You should read this Prospectus and any applicable Prospectus Supplement before you invest in any Securities.

The Corporation’s common shares are listed on the New York Stock Exchange (the “NYSE”) and the Toronto Stock Exchange (the “TSX”) under the symbol “ENB”.

The Securities may be sold directly, on a continuous or delayed basis, through dealers or agents designated from time to time, to or through underwriters or through a combination of these methods. See “Plan of Distribution” in this Prospectus. We may also describe the plan of distribution for any particular offering of the Securities in any applicable Prospectus Supplement.

Each time we offer Securities pursuant to this Prospectus, we will provide you with one or more Prospectus Supplements that will provide specific information about the Securities being offered and describe the specific terms of that offering.

Except as set forth under “Description of Debt Securities and Guarantees” and “Description of Share Capital”, and unless the context otherwise requires, all references in this Prospectus and any Prospectus Supplement to “Enbridge”, the “Corporation”, “we”, “us” and “our” mean Enbridge Inc. and its subsidiaries, partnership interests and joint venture investments.

TABLE OF CONTENTS

NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus, including the documents incorporated by reference into this Prospectus, contain both historical and forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”), and Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the “U.S. Exchange Act”), and forward-looking information within the meaning of Canadian securities laws (collectively, “forward-looking statements”). This information has been included to provide readers with information about the Corporation and its subsidiaries and affiliates, including management’s assessment of the Corporation’s and its subsidiaries’ future plans and operations. This information may not be appropriate for other purposes. Forward-looking statements are typically identified by words such as “anticipate”, “believe”, “estimate”, “expect”, “forecast”, “intend”, “likely”, “plan”, “project”, “target” and similar words suggesting future outcomes or statements regarding an outlook. Forward-looking information or statements included or incorporated by reference in this Prospectus include, but are not limited to, statements with respect to the following: expected earnings before interest, income taxes and depreciation and amortization (“EBITDA”); expected earnings/(loss); expected earnings/(loss) per share; expected future cash flows; expected performance of the Liquids Pipelines, Gas Transmission and Midstream, Gas Distribution, Renewable Power Generation and Transmission, and Energy Services businesses; financial strength and flexibility; expectations on sources of liquidity and sufficiency of financial resources; expected costs related to announced projects and projects under construction; expected in-service dates for announced projects and projects under construction; expected capital expenditures; expected equity funding requirements for our commercially secured growth program; expected future growth and expansion opportunities; expectations about our joint venture partners’ ability to complete and finance projects under construction; expected closing of acquisitions and dispositions and expected timing thereof; estimated future dividends; expected future actions of regulators; expected costs related to leak remediation and potential insurance recoveries; expectations regarding commodity prices; supply forecasts; expectations regarding the impact of the stock-for-stock merger transaction completed on February 27, 2017 between Enbridge and Spectra Energy Corp (the “Merger Transaction”) including our combined scale, financial flexibility, growth program, future business prospects and performance; United States Line 3 Replacement Program; expected impact of the Federal Energy Regulatory Commission policy on treatment of income taxes; the transactions undertaken to simplify our corporate structure; our dividend payout policy; dividend growth and dividend payout expectation; expectations on impact of our hedging program; and expectations resulting from the successful execution of our 2018-2020 Strategic Plan.

Although we believe these forward-looking statements are reasonable based on the information available on the date such statements are made and processes used to prepare the information, such statements are not guarantees of future performance and readers are cautioned against placing undue reliance on forward-looking statements. By their nature, these statements involve a variety of assumptions, known and unknown risks and uncertainties and other factors, which may cause actual results, levels of activity and achievements to differ materially from those expressed or implied by such statements. Material assumptions include assumptions about the following: the expected supply of and demand for crude oil, natural gas, natural gas liquids (“NGL”) and renewable energy; prices of crude oil, natural gas, NGL and renewable energy; exchange rates; inflation; interest rates; availability and price of labor and construction materials; operational reliability; customer and regulatory approvals; maintenance of support and regulatory approvals for our projects; anticipated in-service dates; weather; the timing and closing of dispositions; the realization of anticipated benefits and synergies of the Merger Transaction; governmental legislation; acquisitions and the timing thereof; the success of integration plans; impact of the dividend policy on our future cash flows; credit ratings; capital project funding; expected EBITDA; expected earnings/(loss); expected earnings/(loss) per share; expected future cash flows; and estimated future dividends. Assumptions regarding the expected supply of and demand for crude oil, natural gas, NGL and renewable energy, and the prices of these commodities, are material to and underlie all forward-looking statements, as they may impact current and future levels of demand for our services. Similarly, exchange rates, inflation and interest rates impact the economies and business environments in which we operate and may impact levels of demand for our services and cost of inputs, and are therefore inherent in all forward-looking statements. Due to the interdependencies and correlation of these macroeconomic factors, the impact of any one assumption on a forward-looking statement cannot be determined with certainty, particularly with respect to the impact of the Merger Transaction on us, expected EBITDA, expected earnings/(loss), expected earnings/(loss) per share or estimated future dividends. The most relevant assumptions associated with forward-looking statements regarding

TABLE OF CONTENTS

announced projects and projects under construction, including estimated completion dates and expected capital expenditures, include the following: the availability and price of labor and construction materials; the effects of inflation and foreign exchange rates on labor and material costs; the effects of interest rates on borrowing costs; the impact of weather and customer, government and regulatory approvals on construction and in-service schedules and cost recovery regimes.

The Corporation’s forward-looking statements are subject to risks and uncertainties pertaining to the realization of anticipated benefits and synergies of the Merger Transaction, operating performance, regulatory parameters, changes in regulations applicable to our business, dispositions, the transactions undertaken to simplify our corporate structure, our dividend policy, project approval and support, renewals of rights-of-way, weather, economic and competitive conditions, public opinion, changes in tax laws and tax rates, changes in trade agreements, exchange rates, interest rates, commodity prices, political decisions and supply of and demand for commodities, including, but not limited to, those risks and uncertainties discussed in this Prospectus and in documents incorporated by reference into this Prospectus. The impact of any one risk, uncertainty or factor on a particular forward-looking statement is not determinable with certainty as these are interdependent and our future course of action depends on management’s assessment of all information available at the relevant time. Except to the extent required by applicable law, the Corporation assumes no obligation to publicly update or revise any forward-looking statement made in this Prospectus or otherwise, whether as a result of new information, future events or otherwise. All forward-looking statements, whether written or oral, attributable to the Corporation or persons acting on the Corporation’s behalf, are expressly qualified in their entirety by these cautionary statements.

The debt securities will be issued under an indenture dated February 25, 2005, as amended and supplemented from time to time (the indenture as amended and supplemented, the “Indenture”), between Enbridge, SEP, a wholly owned subsidiary of Enbridge, as guarantor, EEP, a wholly owned subsidiary of Enbridge, as guarantor (each of SEP and EEP a “Guarantor”) and Deutsche Bank Trust Company Americas, as trustee. Debt securities issued under the Indenture will not be offered or sold to persons in Canada pursuant to this Prospectus.

The Indenture does not limit the aggregate principal amount of debt securities which may be issued under the Indenture or otherwise. The Indenture provides that debt securities will be in registered form, may be issued from time to time in one or more series and may be denominated and payable in U.S. dollars or any other currency. Unless otherwise specified in the applicable Prospectus Supplement, debt securities may be issued in whole or in part in a global form and will be registered in the name of and be deposited with The Depository Trust Company or its nominee, Cede & Co.

Unless otherwise indicated in an applicable Prospectus Supplement, the debt securities will be unsecured obligations and will rank equally with all of the Corporation’s other unsecured and unsubordinated indebtedness and will be guaranteed by both Guarantors. See “— Guarantees” below. Enbridge is a holding company that conducts substantially all of its operations and holds substantially all of its assets through its subsidiaries. As at March 31, 2019, the long-term debt (excluding the current portion, as well as guarantees and intercompany obligations between the Corporation and its subsidiaries) of Enbridge and its subsidiaries totaled approximately $60.1 billion, of which approximately $36.5 billion is subsidiary debt. The debt securities issued under this Prospectus will be structurally subordinated to all existing and future liabilities, including trade payables and other indebtedness, of Enbridge’s subsidiaries other than the Guarantors with respect to any guaranteed debt securities. The Indenture does not limit the incurrence of indebtedness and issuance of preferred stock of or by Enbridge’s subsidiaries. Nonetheless, we do not expect either Guarantor to issue any additional debt or any preferred stock after the date of this prospectus.

The Indenture has been filed as an exhibit to the registration statement of which this Prospectus is a part and is available as described above under “Where You Can Find More Information”. The Indenture will be described in a Prospectus Supplement for such debt securities. For further details, prospective investors should refer to the Indenture and the applicable Prospectus Supplement.

Debt securities may be issued under the Indenture bearing no interest or interest at a rate below the prevailing market rate at the time of issuance, and may be offered and sold at a discount below their stated principal amount. The Canadian and United States federal income tax consequences and other special considerations applicable to any such discounted debt securities or other debt securities offered and sold at par which are treated as having been issued at a discount for Canadian and/or United States federal income tax purposes will be described in the applicable Prospectus Supplement.

Unless otherwise indicated in the applicable Prospectus Supplement, Enbridge may, without the consent of the holders thereof, reopen a previous issue of a series of debt securities and issue additional debt securities of such series; provided, however, that in the event any additional debt securities are not fungible with the outstanding debt securities for United States federal income tax purposes, such non-fungible additional debt securities will be issued with a separate CUSIP number so that they are distinguishable from the outstanding debt securities.

Guarantees

Unless otherwise specified in the applicable Prospectus Supplement, each of the Guarantors will fully, unconditionally, irrevocably, absolutely and jointly and severally guarantee the due and punctual payment of the principal of, and premium, if any, and interest on the debt securities and all other amounts due and payable by Enbridge under the Indenture and the debt securities, when and as such principal, premium, if any, interest and other amounts shall become due and payable. The guarantee of any debt securities is intended to be a general, unsecured, senior obligation of each of the Guarantors and will rank pari passu in right of payment with all indebtedness of each Guarantor that is not, by its terms, expressly subordinated in right of payment to the guarantee.

The guarantees of either Guarantor will be unconditionally released and discharged automatically upon the occurrence of any of the following events:

TABLE OF CONTENTS

TABLE OF CONTENTS

DESCRIPTION OF SHARE CAPITAL

In this section, the terms “Corporation” and “Enbridge” refer only to Enbridge Inc. and not to its subsidiaries, partnerships or joint venture interests. The following sets forth the terms and provisions of the existing capital of the Corporation. The following description is subject to, and qualified by reference to, the terms and provisions of the Corporation’s articles and by-laws. The Corporation is authorized to issue an unlimited number of common shares and an unlimited number of preference shares, issuable in series.

Common Shares

Each common share of the Corporation entitles the holder to one vote for each common share held at all meetings of shareholders of the Corporation, except meetings at which only holders of another specified class or series of shares are entitled to vote, to receive dividends if, as and when declared by the board of directors of the Corporation, subject to prior satisfaction of preferential dividends applicable to any preference shares, and to participate ratably in any distribution of the assets of the Corporation upon a liquidation, dissolution or winding up, subject to prior rights and privileges attaching to the preference shares.

Under the dividend reinvestment and share purchase plan of the Corporation, registered shareholders may reinvest their dividends in additional common shares of the Corporation or make optional cash payments to purchase additional common shares, in either case, free of brokerage or other charges.

The registrar and transfer agent for the common shares in Canada is AST Trust Company (Canada) (formerly CST Trust Company) at its principal transfer offices in Vancouver, British Columbia, Calgary, Alberta, Toronto, Ontario and Montréal, Québec. The co-registrar and co-transfer agent for the common shares in the United States is American Stock Transfer & Trust CO LLC at its principal office in Brooklyn, New York.

Shareholder Rights Plan

The Corporation has a shareholder rights plan (the “Shareholder Rights Plan”) that is designed to encourage the fair treatment of shareholders in connection with any take-over bid for the Corporation. Rights issued under the Shareholder Rights Plan become exercisable when a person, and any related parties, acquires or announces the intention to acquire 20% or more of the Corporation’s outstanding common shares without complying with certain provisions set out in the Shareholder Rights Plan or without approval of the board of directors of the Corporation. Should such an acquisition or announcement occur, each rights holder, other than the acquiring person and its related parties, will have the right to purchase common shares of the Corporation at a 50% discount to the market price at that time. For further particulars, reference should be made to the Shareholder Rights Plan, a copy of which may be obtained by contacting the Director, Investor Relations, Enbridge, 200, 425-1st Street S.W., Calgary, Alberta, T2P 3L8; telephone: 1-800-481-2804; fax: 1-403-231-5780; email: investor.relations@enbridge.com.

Preference Shares

Shares Issuable in Series

The preference shares may be issued at any time or from time to time in one or more series. Before any shares of a series are issued, the board of directors of the Corporation shall fix the number of shares that will form such series and shall, subject to the limitations set out in the articles of the Corporation, determine the designation, rights, privileges, restrictions and conditions to be attached to the preference shares of such series, except that no series shall be granted the right to vote at a general meeting of the shareholders of the Corporation or the right to be convertible or exchangeable for common shares, directly or indirectly.

For preference shares issued that are to be convertible into other securities of the Corporation, including other series of preference shares, no amounts will be payable to convert those preference shares.

Priority

The preference shares of each series shall rank on parity with the preference shares of every other series with respect to dividends and return of capital and shall be entitled to a preference over the common shares

TABLE OF CONTENTS

and over any other shares ranking junior to the preference shares with respect to priority in payment of dividends and in the distribution of assets in the event of liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary, or any other distribution of the assets of the Corporation among its shareholders for the purpose of winding-up its affairs.

Voting Rights

Except as required by law, holders of the preference shares as a class shall not be entitled to receive notice of, to attend or to vote at any meeting of the shareholders of the Corporation, provided that the rights, privileges, restrictions and conditions attached to the preference shares as a class may be added to, changed or removed only with the approval of the holders of the preference shares given in such manner as may then be required by law, at a meeting of the holders of the preference shares duly called for that purpose.

TABLE OF CONTENTS

MATERIAL INCOME TAX CONSIDERATIONS

The applicable Prospectus Supplement will describe material Canadian federal income tax consequences to an investor of acquiring any Securities offered thereunder, if applicable, including whether the payments of dividends on common shares or preference shares or payments of principal, premium, if any, and interest on debt securities payable to a non-resident of Canada will be subject to Canadian non-resident withholding tax.

The applicable Prospectus Supplement will also describe material United States federal income tax consequences of the acquisition, ownership and disposition of any Securities offered thereunder by an initial investor who is a United States person (within the meaning of the United States Internal Revenue Code), including, to the extent applicable, any such material consequences relating to debt securities payable in a currency other than the U.S. dollar, issued at an original issue discount for United States federal income tax purposes or containing early redemption provisions or other special items.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION

The Corporation may sell the Securities to or through underwriters, agents or dealers and also may sell the Securities directly to purchasers pursuant to applicable statutory exemptions or through agents.

The distribution of the Securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, or at prices related to such prevailing market prices to be negotiated with purchasers.

The Prospectus Supplement relating to each series of the Securities will also set forth the terms of the offering of the Securities, including to the extent applicable, the initial offering price, the proceeds to the Corporation, the underwriting concessions or commissions, and any other discounts or concessions to be allowed or re-allowed to dealers. Underwriters or agents with respect to Securities sold to or through underwriters or agents will be named in the Prospectus Supplement relating to such Securities.

In connection with the sale of the Securities, underwriters may receive compensation from the Corporation or from purchasers of the Securities for whom they may act as agents in the form of discounts, concessions or commissions. Any such commissions will be paid either using a portion of the funds received in connection with the sale of the Securities or out of the general funds of the Corporation.

Under agreements which may be entered into by the Corporation, underwriters, dealers and agents who participate in the distribution of the Securities may be entitled to indemnification by the Corporation against certain liabilities, including liabilities under securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof.

In connection with any offering of Securities, the underwriters, agents or dealers may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at levels above those which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time.

TABLE OF CONTENTS

ENFORCEMENT OF CIVIL LIABILITIES

The Corporation is a Canadian corporation. While the Corporation has appointed Enbridge (U.S.) Inc. as its agent to receive service of process with respect to any action brought against it in any federal or state court in the United States arising from any offering conducted under this Prospectus, it may not be possible for investors to enforce outside the United States judgments against the Corporation obtained in the United States in any such actions, including actions predicated upon the civil liability provisions of the United States federal and state securities laws. In addition, certain of the directors and officers of the Corporation are residents of Canada or other jurisdictions outside of the United States, and all or a substantial portion of the assets of those directors and officers are or may be located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon those persons, or to enforce against them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of United States federal and state securities laws.
