Internal Migration and Settlement Patterns

How and why Canadians move within the country (interprovincial moves to Alberta and the Maritimes, rural-to-urban migration), the pattern of settlement: the ecumene near the US border, the Windsor–Quebec City corridor, urban and rural shares and the six largest metropolitan areas, northern and Indigenous communities, and the physical and human factors that explain population size, distribution and density.

Key things to remember

  1. 1Internal migration includes interprovincial, rural-to-urban, urban-to-suburban, return and seasonal moves; Alberta has had the largest net interprovincial gains in recent years and Ontario the largest losses (Statistics Canada, to mid-2025).
  2. 2The ecumene is the permanently inhabited part of a country; in 2016 two-thirds (66%) of Canadians lived within 100 km of the US border, on about 4% of Canada's territory.
  3. 3In 2021 nearly three in four Canadians lived in one of 41 census metropolitan areas, and 17.8% lived in rural areas.
  4. 4The six CMAs over one million in 2021 were Toronto, Montréal, Vancouver, Ottawa–Gatineau, Calgary and Edmonton, home to nearly half of all Canadians.
  5. 5Settlement is shaped by physical factors (climate, landforms, soil, water, resources) and human factors (transportation, history, jobs, services, government policy).

In 2022 the Alberta government ran an advertising campaign called "Alberta is Calling" on billboards and transit in Toronto and Vancouver, inviting young workers to move west for cheaper homes and good jobs. Many did. Alberta had the largest net gain from interprovincial migration for twelve quarters in a row up to mid-2025, while Ontario had the largest net loss for fifteen quarters in a row (Statistics Canada). People do not only move to Canada; they also move within it, and those moves, added up over decades, explain the map of where Canadians live.

Moving within Canada

Type of internal migrationWhat it meansRecent Canadian pattern
InterprovincialMoving from one province or territory to anotherNet gains for Alberta and, in the early 2020s, the Maritime provinces; net losses for Ontario and, at times, British Columbia
Rural to urbanMoving from the countryside and small towns to citiesA long-term trend: the share of Canadians in rural areas has fallen at every census since the 1970s
Urban to suburban and exurbanMoving from city centres to suburbs or to towns beyond themFamilies leaving Toronto and Vancouver for cheaper homes in surrounding towns, sometimes far beyond the city
Return migrationMoving back to the home province or communityPeople returning to Atlantic Canada or the North after working elsewhere
Seasonal or temporaryMoving for part of the year or for a jobFly-in, fly-out workers at mines and oil sands sites; seasonal farm workers
Types of internal migration with recent Canadian examples (Statistics Canada census and quarterly estimates).

The push and pull factors from the last lesson work inside Canada too. Housing costs push people out of the Toronto and Vancouver areas; lower costs and jobs pull them to Alberta and Saskatchewan. During the pandemic, remote work let some people keep city jobs while moving to smaller places, and from 2016 to 2021 the Maritime provinces (+4.7%) grew faster than the Prairie provinces for the first time since the 1940s, while Newfoundland and Labrador was the only province to lose population (−1.8%). Young people often move from rural areas and small towns to cities for college, university and work, which is one reason many rural communities are older than average (Lesson 2).

Where Canadians live: the ecumene

Geographers call the permanently inhabited part of a country its ecumene. Canada's ecumene is a thin ribbon along the southern edge. In the 2016 census, two out of three Canadians (66%) lived within 100 km of the Canada–US border, an area that makes up only about 4 percent of Canada's territory, and the three territories together held just over 0.3 percent of the population (Statistics Canada). The busiest stretch is the Windsor–Quebec City corridor along the Great Lakes and the St. Lawrence, home to roughly half of all Canadians and to Toronto, Montréal and Ottawa–Gatineau. You saw the physical reasons in Unit 2: mild climate, fertile lowland soils and easy water routes. The table below adds the human reasons.

FactorHow it affects settlementCanadian example
ClimateMilder climates with longer growing seasons attract more peopleThe south of Canada has the warmest summers and shortest winters
Landforms and soilsFlat land with fertile soil supports farming and is easier to build onThe Great Lakes–St. Lawrence Lowlands vs the rocky Canadian Shield
WaterLakes, rivers and coasts provide drinking water, transportation and tradeMontréal on the St. Lawrence; Vancouver's harbour
ResourcesJobs in mining, forestry, energy or fishing create towns, sometimes in remote placesFort McMurray (oil sands), Sudbury (nickel), Labrador City (iron)
Transportation and historySettlement followed fur trade routes, canals and railways; older cities had a head startPrairie towns spaced along the Canadian Pacific Railway
Jobs, services and connectionsCities attract people because jobs, universities, hospitals and family networks are already thereMost newcomers settle in Toronto, Montréal and Vancouver
Government policyLaws and treaties decided who could settle whereThe Dominion Lands Act gave homesteads to settlers on the Prairies; the reserve system confined many First Nations to small areas
Physical and human factors that shape where people live in Canada.

An urban country

Canada is one of the most urbanized countries in the world. A census metropolitan area (CMA) is a city and its surrounding communities with a total population of at least 100 000, at least 50 000 of whom live in the core. In the 2021 census, close to 27.3 million people, nearly three in four Canadians, lived in one of 41 CMAs, while the share living in rural areas fell for the ninth census in a row, to 17.8 percent (Statistics Canada). Six CMAs had over a million people each, and together they held nearly half of Canada's population.

Canada's six census metropolitan areas with more than one million people in 2021 (Statistics Canada). Calgary and Ottawa–Gatineau were very close, and Alberta's fast growth since 2021 may change the order in the 2026 census.

Northern and Indigenous communities

Outside the ecumene, settlements are small and far apart. Many northern communities have no road connection and depend on air travel, winter roads or a summer sea lift for food, fuel and building materials, which makes everything expensive. Inuit have lived in the Arctic for thousands of years, and in 2021 about 69 percent of Inuit lived in Inuit Nunangat, the Inuit homeland that includes Nunavut, Nunavik (northern Quebec), Nunatsiavut (northern Labrador) and the Inuvialuit Settlement Region (the western Arctic, mostly in the Northwest Territories). The locations of many First Nations reserves reflect treaties, the Indian Act and government decisions, not the communities' own choice of the best land. In 2021, about 41 percent of First Nations people with registered Indian status lived on reserve, and about 801 000 Indigenous people, over 40 percent of the Indigenous population, lived in large urban centres such as Winnipeg, Edmonton and Toronto (Statistics Canada).

Canada compared with the world
Canada's density of about 4.2 people per km² (2021) is among the lowest in the world, similar to Australia, which also crowds most of its people into one favourable zone (its southeastern and southwestern coasts). Japan has more than 300 people per km² and the Netherlands more than 500, and Bangladesh has over 1000. Low density does not mean Canadians live spread out: most live in cities where local densities are thousands of people per km².

Worked examples

Reveal one step at a time and try to beat it to the next line.

Example 1
Explain why Alberta gained more people from other provinces than any other province in the early 2020s, while Ontario lost the most. Use push and pull factors.
Example 2
Using 2021 census data, compare the population density of Ontario (about 14.2 million people on about 892 000 km²) with Prince Edward Island (about 154 000 people on about 5 700 km²). Explain the surprising result.
Example 3
Assess which factor matters most in explaining why so few people live in the Canadian Shield north of Lake Superior.

Where marks get lost

  • Saying Canadians are spread evenly across the country. The national density of about 4 people per km² hides the fact that most people live in a narrow southern band and in cities.
  • Thinking only immigration changes a province's population. Interprovincial migration can add or remove tens of thousands of people a year, as in Alberta and Ontario.
  • Explaining settlement with physical factors only. History, transportation, jobs, services and government policy (including the reserve system) shape where people live too.
  • Mixing up a city and a census metropolitan area. The City of Toronto had about 2.8 million people in 2021, but the Toronto CMA, which includes surrounding municipalities, had about 6.2 million.
  • Treating all Indigenous people as living on reserves or in the North. Over 40 percent of Indigenous people lived in large urban centres in 2021.
