Northern Canada Vessel Traffic Services (NORDREG)

To promote safe and efficient navigation and environmental protection in the Canadian Arctic, a ship reporting system, namely Northern Canada Vessel Traffic Services (NORDREG) Zone, was established. NORDREG accomplishes this by:

  • verifying that ships wishing to travel in the NORDREG Zone are suitably constructed to withstand the ice conditions that they will likely encounter along their routes,
  • monitoring ships’ locations to be able to respond effectively to emergencies,
  • providing support services, for example, providing up-to-date information on ice conditions, advice on ice routes, aids to navigation and icebreaker support when available and considered necessary and organization of convoys as required by prevailing navigation conditions.

Classes of vessels that are required to report

All vessels are encouraged to participate fully, however, the following vessels, which pose the greatest risk to the marine environment, are required to report prior to entering, while operating within and upon exiting the NORDREG Zone:

  • Vessels of 300 gross tonnage or more;
  • Vessels that are engaged in towing or pushing a vessel, if the combined gross tonnage of the vessel and the vessel being towed or pushed is 500 gross tonnage or more; and
  • Vessels carrying as cargo a pollutant or dangerous goods, or engaged in towing or pushing a vessel carrying as cargo a pollutant or dangerous goods.

The NORDREG Zone

Canada’s northern waters that make up the NORDREG Zone are illustrated in Figure 1 below. The NORDREG Zone consists of those waters covered by the Shipping Safety Control Zones and additionally, the waters of Ungava Bay, Hudson Bay and Kugmallit Bay that are not in a shipping safety control zone, the waters of James Bay, the waters of Koksoak River from Ungava Bay to Kuujjuaq, the waters of Feuilles Bay from Ungava Bay to Tasiujaq, the waters of Chesterfield Inlet that are not within a shipping safety control zone and Baker Lake, and the waters of Moose River from James Bay to Moosonee.
