For a complete listing of all VHF channels and the areas in which they are used in Canada, visit the Industry Canada website. Here are the channels most commonly used by Marine Communications and Traffic Services (MCTS) Centres on Canadian waters in the Central and Arctic regions.

  • Channels 1-3, 23-28, 60, 64, 84-86: Public correspondence (marine operator).
  • Channel 11-12: Vessel traffic regulating.
  • Channel 13: Intership navigational traffic (bridge-to-bridge).
  • Channel 16: Distress and safety calls to Canadian Coast Guard and others, and to initiate calls to other vessels; often called the "hailing" channel. When hailing, contact the other vessel, quickly agree to another channel, and then switch to that channel to continue conversation. This channel is continuously monitored by all MCTS Centres.
