With the recent departure of the CCGS Louis S. St-Laurent from Arctic waters, the Canadian Coast Guard’s 2018 Arctic operational season is nearing an end. Seven icebreakers were deployed to the Arctic, providing safe escorts of ships through ice-covered waters, responding to incidents including search and rescue and environmental response, supporting safe navigation, Fisheries and Oceans science missions, and training operations with partners. As of November 5, the Marine Communications and Traffic Services (MCTS) centre in Iqaluit provided support for 166 vessels in the Northern Canada Vessel Traffic Services Zone (NORDREG). These vessels include Canadian Coast Guard ships, cargo ships, tankers, cruise ships, research vessels, bulk carriers, tugs, fishing vessels, pleasure crafts and adventurers. Extreme and challenging ice conditions this season resulted in difficult transit of some vessels in the Northwest Passage. In addition to ice-breaking services, Coast Guard successfully responded to 20 search and rescue and 14 environmental response incidents. The Coast Guard’s Arctic season will resume again in May 2019.
