Icebreaking at the Port of Thunder Bay, Ontario

News release

December 17, 2019

Montreal, Quebec – The Canadian Coast Guard advises residents of Thunder Bay, Ontario on Lake Superior that icebreaking operations have started and will continue until the closure of the Sault Ste. Marie locks on January 15, 2020. The purpose of this annual operation is to break up the ice in order to allow commercial vessels safe and efficient movement into and out of the Port of Thunder Bay.

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

Coast Guard icebreaking service 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.

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.
