Nautical Charts and Services

Canadian Hydrographic Service (CHS)’s exceptional nautical charts and navigational products help ensure the safe navigation of Canada’s waterways.  Our charts are the ‘road maps’ that guide mariners safely from port to port.  With increasing commercial shipping, fishing activity, recreational boating, and the development of ocean resources, the role of CHS is more vital than ever.

All vessels in Canadian waters must carry and use nautical charts and related publications pursuant to the Canada Shipping Act, 2001, Charts and Nautical Publications Regulations, that are issued by, or on the authority of, the Canadian Hydrographic Service.
