<P> The Canadian Rockies ( French : Rocheuses canadiennes ) comprise the Canadian segment of the North American Rocky Mountains . They are the eastern part of the Canadian Cordillera , which is a system of multiple ranges of mountains which runs from the Canadian Prairies to the Pacific Coast . The Canadian Rockies mountain system comprises the southeastern part of this system , lying between the Interior Plains of Alberta and Northeastern British Columbia on the east to the Rocky Mountain Trench of BC on the west . The southern end borders Idaho and Montana of the USA . In geographic terms the boundary is at the Canada / US border , but in geological terms it might be considered to be at Marias Pass in northern Montana . The northern end is at the Liard River in northern British Columbia . </P>
