Canadian National Railway Company (CN)

CN remains committed to running its railway safely and efficiently and building a level of trust and collaboration with the communities where they operate.

To that end, CN is reaching out to advise you of our vegetation control activities in your area between April and October 2023. A regularly updated schedule is available at online.

If not managed properly, trees, brush or other vegetation can severely compromise rail and public safety. Vegetation can impede the view motorists have of oncoming trains and increase the risk of crossing accidents. Moreover, unwanted vegetation can damage the integrity of the railbed, interfere with signals and switches, contribute to track side fires, compromise employee and citizen safety, and reduce visibility for train crews at road crossings/train control signals and track side warning devices, to name a few of the potential risks.

CN's annual vegetation control program is designed to mitigate these risks by managing brush, weeds and other undesirable vegetation. CN’s vegetation control program is critical to ensure safe operations and contributes to the overall safety of the communities in which they operate.

Please also find enclosed a letter from CN's Senior System Manager - Environmental Assessment regarding the program that may be of further assistance:
