List of regions of Canada — national and provincial divisions

National-level groupings

Canada’s national regions are collections of provinces and territories used for constitutional and federal purposes. These broad groupings are reflected in how seats in the upper chamber of Parliament are allocated and sometimes guide national policy frameworks. They are not a single uniform map; rather, the Constitution and subsequent practice recognise a handful of large regions that group neighbouring provinces and territories for representational balance.

Provincial and territorial subdivisions

Within provinces and territories the variety of regions is much greater. Examples include counties and regional municipalities in many provinces, regional districts in British Columbia, regional county municipalities (RCMs) and administrative regions in Quebec, and census divisions used by Statistics Canada. Territories use larger administrative regions to reflect low population density and Indigenous governance structures. These subdivisions can be used for local government, land use planning, health authorities, education districts and service delivery.

Statistical and functional regions

Statistics Canada produces several layered systems—provinces and territories, census divisions, census metropolitan areas and economic regions—that support demographic analysis, economic planning and program delivery. Other functional regions arise around watersheds, transportation corridors, or cultural and linguistic communities. Regional boundaries for one purpose rarely match boundaries for another, which can complicate comparison and coordination.

Uses and notable distinctions

Regions are tools for organizing representation, administering programs, collecting statistics and planning infrastructure. The same name (for example “Eastern” or “Northern”) may refer to very different territories depending on context. For detailed, authoritative maps and lists of the specific regions used by federal agencies and by each province or territory, consult official government publications and the statistical agency’s regional definitions via regional resources.
