Since January 1, 2017, all official digital charts produced by the Canadian Hydrographic Service (CHS) have been available online. They are no longer distributed on CD.

CHS distributes nautical charts through a dealer network that serves Canada and the entire world. You can use this site to find the nautical charts that you need and choose the dealer from which you will order them. Then use the new CHS Chart Registry Service to download and register your electronic charts. Registering your charts allows you access to the most recent updates for the duration of your licence.

CHS nautical charts are available in two digital formats: as Raster Navigational Charts (RNC) in the BSBv4 format or as Electronic Navigational Charts (ENC) in the S-57 vector format. They are offered separately or in collections. Used with a navigation software, the two formats contribute to navigational safety.
