The list of regions in Canada is a summary of geographical areas on a hierarchy that ranges from national (groups of provinces and territories) at the top to local regions and sub-regions of provinces at the bottom. Administrative regions that rank below a province and above a municipality are also included if they have a comprehensive range of functions compared to the limited functions of specialized government agencies. Some provinces and groups of provinces are also quasi-administrative regions at the federal level for purposes such as representation in the Senate of Canada. However regional municipalities (or regional districts in British Columbia) are included with local municipalities in the article list of municipalities in Canada.
National regions
The six geographical regions of Canada defined by Statistics Canada:
Regional representation on the Supreme Court of Canada is governed more by convention than by law. Quebec is the only region with a legally guaranteed quota of three judges on the bench. The other regions are usually represented by three judges from Ontario, two from Western Canada (typically but not formally one from British Columbia and one from the Prairie Provinces) and one from Atlantic Canada. The three territories do not have any separate representation on the Supreme Court.
The various models are derived from the three-region scheme by progressively subdividing the western and eastern regions (the northern region is the same for all models) into smaller and smaller units consisting of provinces or groups of provinces. If the models are not treated as mutually exclusive, eight distinct national regions can be identified when the three western regions of the seven region scheme are combined with the two Atlantic regions of the Senate method and the Ontario, Quebec, and northern regions common to both schemes.
As of 5June2026[update], approximately 98.2% of Canadians can speak English, French, or both:
English – 69.0%
English and French – 18.0%
French – 11.2%
Sparsely populated area 0.4 inhabitants per square kilometre (1.0 inhabitant per square mile)
An inter-provincial region includes more than one province or territory but does not usually include the entirety of each province or territory in the group. However, the geographic or cultural features that characterize this type of region can sometimes lead to the relevant provinces or territories being seen as regional groups like British Columbia-Yukon and Alberta-Northwest Territories.

English Canada, sometimes known as the Rest of Canada, with Quebec usually excluded despite the presence of scattered English speaking populations in the southern part of the province which are increasingly part of the bilingual belt
Arctic Archipelago, a large group of Canadian islands in the Arctic Ocean that lies partly in Nunavut, partly in the Northwest Territories, and one, Herschel Island, that is part of Yukon.
Canadian Cordillera which links most of British Columbia and Yukon with some smaller adjacent areas of Alberta and the Northwest Territories to form a single region of mountains and plateaus
Taiga Cordillera that includes much of northern Yukon and an adjacent area of the Northwest Territories
Boreal Cordillera that links northwestern British Columbia with southern Yukon
Southern Arctic Ecozone that includes the Arctic coast of Yukon, the Northwest Territories, and an adjacent part of Nunavut
Taiga Plains Ecozone that include parts of northeastern Yukon, the Northwest Territories, northeastern British Columbia, and northwestern Alberta
Boreal Plains Ecozone, which links parts of northern British Columbia, Alberta, and Saskatchewan with part of central Manitoba and a small part of the Northwest Territories
Peace River Country, a valley area of parkland and boreal plain that links parts of northern British Columbia and northern Alberta as a part of the larger Boreal Plains region
Aspen parkland, a long but relatively narrow transitional region in the Prairie Provinces that separates the boreal forests of the north from the prairie grasslands further south
Cypress Hills that links the hilly areas of southern Alberta with their counterparts in southern Saskatchewan
Canadian Shield, a vast region centred around Hudson Bay that includes parts of every province except British Columbia and the Maritimes, and parts of every territory except Yukon
Southern Arctic Shield, parts of the Canadian Shield separated by Hudson Bay and located mostly in Nunavut and the most northerly region of Quebec
Taiga Shield, parts of the Canadian Shield located west of Hudson Bay from the Northwest Territories to the far northern fringe of the Prairie Provinces, and east of Hudson Bay and James Bay from Quebec to Labrador
Boreal Shield, located mostly south of Hudson Bay and James Bay from northeastern Alberta to southeastern Labrador
Appalachian Uplands, an old, partly eroded system of mountain ranges, hills, and plateaus that extends into southeastern Canada from the eastern United States
Acadia, a largely historical region that links parts of the Maritimes and parts of eastern Quebec within the Appalachian region
The provinces and territories are nearly all sub-divided into regions for a variety of official and unofficial purposes. The geographic regions are largely unofficial and therefore somewhat open to interpretation. In some cases, the primary regions are separated by identifiable transition zones, particularly in Alberta, Saskatchewan, and Ontario. The largest provinces can be divided into a number of primary geographic regions of comparatively large size (e.g. southern Ontario), and subdivided into a greater number of smaller secondary regions (e.g. southwestern Ontario). The primary and secondary regions in Ontario are mainly non-administrative in nature. However, they tend to be defined as geographic groupings of counties, regional municipalities, and territorial districts, so that the regions are defined by a system or collection of borders that have local administrative importance.
In other large provinces, the primary and secondary geographic regions are defined more strictly by topographical and ecological boundaries. In geographically diverse provinces, the secondary regions can be further subdivided into numerous local regions and even sub-regions. British Columbia has a much greater number of local regions and sub-regions than the other provinces and territories due to its mountainous terrain where almost every populated lake, sound, and river valley, and every populated cape and cluster of small islands can claim a distinct geographical identity. At the other extreme, Prince Edward Island is not divided into any widely recognized geographic regions or sub-regions because of its very small size and lack of large rivers or rugged terrain. New Brunswick's small size renders it dividable into local geographic regions only.
Several provinces and territories also have supra-municipal administrative regions. Their borders mostly do not harmonize with the geographic regions, so they are not considered subdivisions or groupings of the latter.
