Canada's population diversity
Explanation:
The population map shows that Canada’s population is unevenly distributed. This uneven distribution has occurred because of climate and the availability of economic resources and opportunities. Climate has played a large role in where people live in Canada. Northern Canada is characterized by tundra and subarctic climate regions. These regions are incredibly cold and difficult for people to live in. Because of this, about eighty percent of Canada’s population lives near the United States border, where climates are a bit milder and more bearable. Heavily populated areas of Canada include those next to the Great Lakes and the St. Lawrence River. There, citizens can utilize the country’s natural resources, conduct trade with other countries, or take advantage of jobs provided in the area.
