Why do about 90% of Canadians live within 100 miles of the U.S. border?

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.
