CN has prepared this Winter Plan as required by the provisions of the Canada Transportation Act.

The Plan does two things. First, it outlines the challenges CN faces operating in Canadian winter conditions. And second, it sets out the actions and innovations we have implemented to enable us to maintain our operations through the winter at a level acceptable to the needs of all our customers while ensuring we continue to operate in a safe and efficient manner. It serves as a framework to ensure we meet the needs of our customers and stakeholders in the challenging winter months ahead.
