Mackenzie River

Permafrost underlies about three-quarters of the watershed, reaching up to deep in the Mackenzie Delta. As a whole, the Mackenzie basin receives only meager to moderate rainfall, averaging over the entire basin, though mountain areas experience much higher precipitation, and areas near and north of the Arctic Circle receive much lower precipitation.
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.
