National Navigational Warning Issuing Service

The Canadian Coast Guard’s (CCG) Marine Communications and Traffic Services (MCTS) program has launched a national navigational warning (NAVWARN) issuing service to replace the existing domestic Notice to Shipping (NOTSHIP) services.

The new NAVWARN Issuing System will provide greater harmonization in both the format and content of navigational warnings.

Visitors will be able to search NAVWARNs or subscribe to receive NAVWARNs by email, by visiting the following web page: http://nis.ccg-gcc.gc.ca

Mariners and clients are advised that the NAVWARN Issuing Service will launch in January 2019 as indicated below:
