CNR Canadian National Railway Company

CN (TSX: CNR) (NYSE: CNI) announced today that it is seeking comments regarding its Interim Extreme Weather Fire Plan. The Plan presents measures to increase prevention, monitoring and response to wildfire risks when the fire danger level for a given area is “extreme”. These measures will supplement existing practices and allow CN to serve our customers while protecting neighbouring communities.

Safety is a core value at CN. It is also a shared responsibility, which is why CN is seeking the input of local communities and governments, including Indigenous Governments or other Indigenous Governing bodies on its Plan.

Those who wish to provide such input and feedback are invited to do so on or before August 30, 2021 by using the following web-based platform www.cn.ca/extremeweatherplan or by contacting CN via phone at 1-888-888-5909.
