Icebreaking near Port of Thunder Bay, Ontario

March 20, 2024

Sarnia, Ontario - The Canadian Coast Guard advises residents of Thunder Bay, Ontario that the CCGS Samuel Risley will carry out icebreaking operations in the area on or around March 22, 2024. The purpose of this operation is to break up the ice to allow commercial vessels safe and efficient movement.

It is recommended that all traffic on the ice, including pedestrians, fishers, snowmobilers, and all-terrain vehicle operators, leave the ice during icebreaking operations. The ice may move, creating a real danger for anyone on it. Additionally, plan activities carefully and use extreme caution after operations are complete as the ice will remain unstable even once the icebreaker has left the area.

The date and assets are subject to change with no notice, as activities could begin before or after that period, depending on operational requirements or weather conditions.

Icebreaking on the Great Lakes and connecting waterways is delivered through close co-operation between the Canadian and United States Coast Guards. By working together, the two Coast Guards ensure scheduled vessel traffic can move through the shipping channels and in and out of community harbours. Vessels will be assigned as needed to provide this service.
