The Canadian Coast Guard (CCG) issues Notices to Shipping (NOTSHIP) to inform mariners about hazards to navigation and to share other important information.
NOTSHIP alerts are broadcast by radio by Marine Communications and Traffic Services (MCTS). Written NOTSHIP alerts are issued when the location of the hazard is beyond broadcast range, or when the information remains in effect for an extended period of time.
