List of longest rivers of Canada
Nine rivers in this list cross international boundaries or form them. Four—the Yukon, Columbia, Porcupine, and Kootenay—begin in Canada and flow into the United States. Five—the Milk, Pend d'Oreille, Saint Lawrence, Red, and Saint John—begin in the United States and flow into Canada. Of these, the Milk and the Kootenay cross the international border twice, the Milk leaving and then re-entering the United States, the Kootenay leaving and then re-entering Canada. The drainage basins of these nine rivers extend into both countries; in addition, the drainage basins of six others—the Fraser, Assiniboine, South Saskatchewan, Saskatchewan, Nelson, and Winnipeg—extend into the United States even though their main stems flow entirely within Canada.
Striped bass
In Canada there are no landlocked striped bass, but a large number of bass overwinter in Grand Lake, Nova Scotia. They migrate out in early April into the Shubenacadie River to spawn. These bass also spawn in the Stewiacke River (a tributary of the Shubenacadie). The Shubenacadie River system is one of five known spawning areas in Canada for striped bass, with the others being the St. Lawerence River, Miramichi River, Saint John River, Annapolis River and Shubenacadie/Stewiacke Rivers.
