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.
Houseboat
In Canada, houseboats are gaining popularity in British Columbia, Ontario, and Quebec as there is an abundance of perfectly suited rivers and lakes for houseboaters to enjoy. Houseboats in Canada are generally motorised and used recreationally, rather than as a permanent dwelling; this is mainly due to cold winter temperatures and accompanying frozen waterways. The Rideau Canal system is a historic waterway known for its picturesque setting and quaint villages. The town of Sicamous, on Shuswap Lake, British Columbia, is said to be the "Houseboat Capital of the World". Float houses are relatively common along the Pacific coast. A "float" is a raft, raft-like construction or flat bottom boat.
