Final answer:
Most Canadians live in a narrow band close to the US border in provinces like Ontario, Quebec, and British Columbia, due to the milder climate, better opportunities, and the area's suitability for agriculture and urban development.
Step-by-step explanation:
Overview of Canadian Population Distribution
The majority of Canadians live in a narrow band in the southern part of Canada, close to the US border. This region includes the provinces of Ontario, Quebec, British Columbia, the prairies, and the Atlantic coast. Ontario is the most populous with about 39 percent of the country's population, followed by Quebec with 23 percent. British Columbia, specifically the city of Vancouver, is also significant, and is a major port due to its location west of the Rocky Mountains. The prairie provinces and the Atlantic provinces together account for 25 percent of the population. The northern regions of Canada are sparsely populated due to extreme climatic conditions and limited agricultural viability.
Most Canadians choose to live near the US border because of the milder climate, suitable terrain for agriculture, and the closely intertwined economies between Canada and the United States. Additionally, the southern regions are where the majority of urban centers, economic activity, and infrastructure are located, providing a higher standard of living and more opportunities.
