The Canadian Coast Guard (CCG) maintains a number of major bases and operating stations on the Atlantic and Pacific coasts, as well as in the St. Lawrence River, Great Lakes and major navigable inland waterways such as Lake of the Woods, Lake Winnipeg, and Great Slave Lake/Mackenzie River.
Currently, there are no vessels permanently based in the eastern Arctic, although CCG vessels and aircraft frequently operate there, staging out of bases on the Atlantic coast and supported by a base in Iqaluit, Nunavut.
