Canadian Ice Service
What we do
The Canadian Ice Service is Canada's leading authority on ice and iceberg information. The Service provides ice charts, forecasts, alerts, satellite-derived imagery, and reports.
This information helps:
- protect Canadians, their property and their environment, by warning of dangerous ice conditions
- support safe shipping and efficient maritime operations
- provide essential ice knowledge to support sound environmental policies
Who we work with
We work closely in partnership with other Government of Canada departments such as:
- Canadian Coast Guard (CCG): We work closely with the Canadian Coast Guard to support safe navigation in ice-covered waters. During peak ice season, Coast Guard-operated ice reconnaissance flights provide valuable observations that complement satellite imagery and help improve ice analysis.
- Department of National Defence (DND): We provide ice information, analysis, and forecasts that help the Department of National Defence safely plan and conduct operations in Canada's coastal and Arctic waters.
This information is useful to:
- the marine industry
- all levels of government
- communities
- researchers
- meteorologists
North American Ice Service
The North American Ice Service is a collaboration between:
- the Canadian Ice Service
- the United States National Ice Center
- the United States Coast Guard’s International Ice Patrol
Together, we provide consistent, reliable ice information across shared waterways and areas of international significance. By combining expertise and observations, the North American Ice Service helps mariners make informed decisions and supports safe and efficient navigation.
This collaborative group produces joint ice and iceberg charts and bulletins for key areas, including:
- The Great Lakes (ice conditions)
- The Bering Strait (ice conditions)
- The waters off Newfoundland and Labrador (iceberg information)
