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

Notices to Shipping

Notices to shipping (NOTSHIPs) are notices concerning Navigational Aid changes or defects, fishing zones, military exercises, dredging, or other marine hazards. Contain information for all boaters and is intended to inform the marine community of hazards, current activities and other pertinent information.

Broadcast Notices to Shipping

Broadcast Notices to Shipping contain information releases of an urgent nature, broadcast through Marine Communication and Traffic Services (MCTS) Centres, where applicable. They cover the establishment, condition or change in condition of a marine facility, service, procedure, or hazard provided to the mariner and the public immediately, and remains in effect for a limited period of time or until the matter is covered by a written NOTSHIP or Notice to Mariners.

Written Notices to Shipping

Written Notices to Shipping contain information which is anticipated to remain in effect for an extended period of time as determined by the RMIC. These notices have previously been broadcast in full for an initial period of 48 hours and then placed for an additional period of 5 days, on an Active NOTSHIP List which lists the NOTSHIP number and gives a brief description of each one.
