DISTRIBUTION INCREASE The Board of Trustees of Brookfield Canada Office Properties has declared an 8% increase to the yearly distribution per trust unit from $1.08 to $1.17, effective with the distribution payable on October 15, 2012 to holders of trust units of record at the close of business on September 28, 2012. Distribution payment on trust units is reviewed quarterly by the Trustees to assess the appropriateness of the distribution in light of changes to reported cash-flow.

Net Operating Income, FFO and AFFO This press release and accompanying financial information make reference to net operating income, funds from operations ("FFO") and adjusted funds from operations ("AFFO") on a total and per unit basis. Net operating income is defined by us as income from commercial property operations after direct property operating expenses, including property administration costs have been deducted, but prior to deducting interest expense, general and administrative expenses and fair value gains (losses). FFO is defined by us as net income prior to one-time transaction costs, fair value gains (losses), and certain other non-cash items if any. AFFO is defined by us as FFO net of normalized second-generation leasing commissions and tenant improvements, normalized sustaining capital expenditures and straight-line rental income. The Trust uses net operating income, FFO and AFFO to assess its operating results. Net operating income is important in assessing operating performance and FFO is a widely used measure to analyze real estate. AFFO is typically a measure used to asses an entity's ability to pay distributions. The components of net operating income, FFO and AFFO are outlined in the financial information accompanying this press release. Net operating income, FFO and AFFO do not have any standard meaning prescribed by IFRS and therefore may not be comparable to similar measures presented by other companies.

Distribution Declaration The Board of Trustees of Brookfield Canada Office Properties announced a distribution of $0.09 per Trust unit payable on September 14, 2012 to holders of Trust Units of record at the close of business on August 31, 2012. Unitholders resident in Canada will receive payment in Canadian dollars and unitholders resident in the United States will receive their distributions in U.S. dollars at the exchange rate on the record date, unless they elect otherwise.

(1) As the components used in calculating AFFO vary quarter over quarter, a
normalized level of activity is estimated based on historical spend levels
as well as anticipated spend levels over the next few years. Sustaining
capital expenditures relate to capital items that are required to maintain
the properties in their current operating state and exclude projects that
are considered to add productive capacity.
