Nautical charts and publications
Canadian Hydrographic Service (CHS)'s nautical charts and publications help ensure the safe navigation of Canada's waterways. Browse our catalogue of over 2,000 nautical charts and publications using the links below.
All vessels in Canada’s waters must carry and use nautical charts and related publications from the Canadian Hydrographic Service in accordance with the
Charts and Nautical Publications Regulations, 1995. Please
contact a dealer near you to purchase paper or digital charts to be used for navigation.
FAQ:
Am I required by law to carry CHS charts? What are the Charts and Nautical Publications Regulations of the Canada Shipping Act?
Answer:
Vessels of any kind in Canada have an obligation to carry and use official charts and publications issued by or on the authority of the Canadian Hydrographic Service, and to keep them up to date. The
chart carriage regulations are listed in the
Charts and Nautical Publications Regulations, 1995 under the
Canada Shipping Act, 2001.
- CHS paper charts meet the requirements of the chart carriage regulations.
- CHS digital charts meet the requirements of the chart carriage regulations under certain circumstances:
- CHS Electronic Navigational Charts (ENCs) meet the requirements provided they are used with an Electronic Chart Display and Information System (ECDIS).
- CHS Raster Navigational Charts (RNCs) meet the requirements only if paper charts are carried and used as a backup.
For further information on which charts meet the official requirements, please see our list of
CHS Official Products and CHS Licenced Manufacturers.
