Final answer:
The Canadian Cordillera, encompassing the Rocky Mountains and coastal ranges in western Canada, has the highest elevations in the country.
Step-by-step explanation:
The area of Canada with the highest elevations is the Canadian Cordillera. This region includes the Rocky Mountains and the coastal ranges located in western Canada. It is known not only for its high elevations but also as a place rich in natural resources, which contributes to industries such as mining and lumber mills. For example, in the Yukon Territory within the mountains, there was a historically significant gold rush. Additionally, Vancouver, situated in British Columbia along the coast, is a major port that facilitates trade with the Pacific Rim due to its proximity to these mountainous areas.
