Each year, CN is required to manage vegetation on its right-of-way. Managing this vegetation contributes to mitigating fire risks and enhances the efficiency of inspection of track infrastructure.

The spray program is not being done for aesthetic reasons.

To ensure safe railway operations, CN will conduct its annual spray program on its rail lines in the province of Ontario. A certified professional (Davey Tree Expert Company of Canada, Ltd., 1-800-465-6367) will apply herbicides on and around the railway tracks (primarily along the 24-foot graveled area/ballast). Product requirements for setbacks in the vicinity of dwellings, aquatic environments and municipal water supplies will be met.

CN may use the following products:

CN only uses herbicides that have been approved for use in Canada and in the province within which they are applied. The program is expected to take place from April to October 2026.

All CN land is private property, accessible to CN employees and approved contractors only.
