St-Laurent is collecting high-resolution geoscience and hydrographic data in the Arctic. The mission demonstrates Canada’s ability to operate safely and effectively in one of the world’s most challenging environments while advancing important national interests in the Arctic.

Canadian Coast Guard icebreakers are among the most capable and powerful in the world, operated by some of the most experienced crews, and able to reach remote and hard-to-access areas across Canada’s Arctic. Through its enduring presence and operations in Canada’s Arctic waters, the Canadian Coast Guard reinforces Canada’s sovereignty and security in the North.      The Canadian Coast Guard’s summer operational season runs annually from June to November to support Northern communities, carry out services, and support Government of Canada Arctic missions.
