Each summer the Canadian Coast Guard sends its fleet of icebreakers to the Arctic to support shipping, carry out scientific research, engage in Search & Rescue and any other tasks that may be assigned.
CCGS Des Groseilliers was initially designated as a 1200 class icebreaker. It is named after Medard Chouart des Groseilliers, a close associate of Pierre-Esprit Radisson. Both men were involved in explorations west of the Great Lakes and in the founding of the Hudson's Bay Company. The ship entered service in 1982.

The sister-ship, CCGS Pierre Radisson, is currently at the shipyard in Port Weller, Ontario; just above Lock 1 of the Welland Canal. Both the Des Gros and the Radisson have been to the Great Lakes to assist with spring breakout and ship escorts.

Below: Unlike many other coast guard aviation units around the world, the primary role of the Canadian Coast Guard's helicopters isn't search & rescue (SAR) - that role falls to the Royal Canadian Air Force. CCG helicopters can, and do, assist with SAR taskings if called upon, but they primarily serve to ensure the safety of marine traffic, largely through the construction and maintenance of navigational and communication aids that are only accessible by air.
Additional responsibilities include the support of Coast Guard icebreakers in the form of aerial reconnaissance, environmental response, supporting ongoing scientific research projects.
