Canada has six main geographic regions - Atlantic Canada, Eastern Canada, the Prairie Provinces, the Rocky Mountain Region, the Pacific Coast, and the Arctic Region. Each region has distinct physical features, natural resources, and industries. The most populated regions are Eastern Canada, where the majority of Canadians live in cities like Toronto and Montreal, and the Prairie Provinces, which serve as the main agricultural area of Canada. Fishing, mining, logging, and oil production are important industries across the different regions. Overfishing has negatively impacted fish populations in some coastal areas.
