Federal authorities are investigating Canadian National Railway for potential violations of the Railway Safety Act. This follows a train crew's evacuation from a locomotive engulfed by wildfire flames earlier this week in northwestern Ontario. Transport Canada conducts an oversight review. Employment and Social Development Canada assesses potential health and safety violations.

A widely shared video depicted the incident, showing the train surrounded by burning trees. A railworkers' union reported the crew received treatment for smoke inhalation. The union urged CN to cease operations through active wildfire zones. CN has suspended rail operations in a portion of the affected area. The company is conducting its own investigation into the circumstances.
