Because Canada’s land area is huge but most of its hospitable, economically useful land is along the southern edge that neighbours the United States. Key reasons:
- Climate and agriculture: Much of Canada north of that 100-mile belt is subarctic or arctic (boreal forest, tundra, permafrost) with short growing seasons. The milder, more fertile areas suitable for farming and comfortable settlement lie in the south.
- Physical geography and resources: The Canadian Shield, mountains and far-north islands are sparsely habitable and expensive to develop. The south contains most of the arable plains, river valleys (St. Lawrence, Great Lakes), and coastal regions where cities grew.
- Historical settlement patterns: European settlement, trade routes and early capitals developed along southern waterways (St. Lawrence, Great Lakes, Pacific coast). After the American Revolution and during 19th-century expansion, immigration and infrastructure concentrated in the south.
- Transportation and economy: Railways, roads and ports were built to connect southern population and trade hubs. Proximity to the huge U.S. market and cross-border economic ties attracted industry and jobs to border regions (e.g., Toronto–Detroit–Buffalo–Windsor corridors, Vancouver–Seattle).
- Urbanization: Larger cities (Toronto, Montreal, Vancouver, Ottawa region, the Prairie provincial capitals) are all in the southern belt, and most newcomers settle where jobs, services and infrastructure exist.
Put simply: Canada is a very large country with most of the land unsuitable or costly for dense settlement, so people cluster in the relatively narrow, more hospitable strip along the U.S. border.
