Final answer:
Over half of Canada's population lives in Ontario, and more than 90 percent of Canadians live within 150 miles of the US border, mainly in urban areas.
Step-by-step explanation:
More than half of the people in Canada live in the province of Ontario, which is home to approximately 39 percent of the country's population. Alongside Ontario, provinces like Quebec, British Columbia, the prairie provinces, and the Atlantic coast contribute to the majority of Canada's population distribution. It is notable that over 90 percent of Canadians reside within 150 miles of the US border. The vast majority of Canadians living in urban areas further demonstrates the trend of populations clustering in cities, especially in southern regions that are more habitable and economically tied to the United States.
