Canadas længste floder

Blandt Canadas længste floder er der 47 som er over 600 km lange. Ni af disse floder krydser internationale grænser, eller danner dem. Fire — Yukon, Columbia, Porcupine og Kootenay — begynder i Canada og løber ind i USA. Fem — Milk, Pend d'Oreille, Saint Lawrence, Red og Saint John — begynder i USA og løber ind i Canada. Af disse krydser Milk og Kootenay grænsen to gange.^[1] Afvandingsområdet for disse ni floder ligger i begge lande; Dertil ligger en del af afvandingsområdet for yderligere seks floder — Fraser, Assiniboine, South Saskatchewan, Saskatchewan, Nelson og Winnipeg — i USA, selv om hele deres hovedløb ligger i Canada.

Mackenzie River er den længste flod i Canada hvis man regner den fra udmundingen Beauforthavet til en af de øvre bifloder Finlay River i Rocky Mountains i det nordlige British Columbia. Hovedstrømmen, som er en væsentlig kortere del af Mackenzie, er fremhævet.

Den primære kilde for data i listen er The Atlas of Canada. Vandføringen gælder for flodens udmunding med mindre andet er anført.

Floden løber ikke udelukkende i Canada.
