List of the 100 largest population centres in Canada
Population centre, in Canadian census data, is a populated place, or a cluster of interrelated populated places, which meets the demographic characteristics of an urban area, having a population of at least 1,000 people and a population density of no fewer than 400 persons per square km2.
Statistics Canada listed 942 population centres in its 2011 census data; 513 of them, 54 per cent of all population centres in Canada, were located in Ontario or Quebec, the two most populous provinces.
The term "population centre" was chosen in order to better reflect the fact that urban vs. rural is not a strict division, but rather a continuum within which several distinct settlement patterns, and several competing interpretations of the distinction, may exist. For example, a community may fit a strictly statistical definition of an urban area, but may not be commonly thought of as "urban" because it has a smaller population, or because it functions socially and economically as a suburb of another urban area rather than as a self-contained urban entity, or because it is geographically remote from other urban communities.
Accordingly, the new definition set out three distinct types of population centres: small (population 1,000 to 29,999), medium (population 30,000 to 99,999) and large (population 100,000 or greater). Despite the change in terminology, however, the demographic definition of a population centre remains unchanged from that of an urban area: a population of at least 1,000 people where the density is no fewer than 400 persons per square km2.
A population centre does not necessarily correspond to the boundaries of a municipality or of a census division. For example, a less densely populated area within a city's municipal boundaries may not be included as part of its population centre, while neighbouring municipalities that directly continue a city's urban core population will be included.
For example, the population centre of Toronto extends into neighbouring Peel Region, Halton Region, Durham Region and York Region, encompassing places such as Oakville, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Aurora, Newmarket, Pickering and Ajax. Despite this, numerous other communities which are considered part of the Greater Toronto Area for political purposes are not part of the population centre of Toronto; because a belt of more rural settlement or undeveloped wilderness separates them geographically from the primary band of urban settlement, communities such as Milton, Georgetown, Caledon, Bolton, Nobleton, Bradford and Stouffville instead form their own separate small or medium population centres. However, a population centre does not cross the boundaries of a Census Metropolitan Area; even though the band of continuous urban development emanating outward from downtown Toronto along the shore of Lake Ontario extends even further into Hamilton and Oshawa, these two cities are both considered separate CMAs by Statistics Canada rather than being part of Toronto's, and accordingly each is also considered a distinct population centre.
Conversely, a single municipality may also contain more than one distinct population centre, if less densely populated or undeveloped regions separate more urbanized areas from one another. For example, Ottawa currently has seven distinct population centres (Ottawa-Gatineau, Constance Bay, Kanata, Richmond, Osgoode, Manotick and Metcalfe), the neighbouring city of Gatineau has a secondary population centre at Buckingham in addition to its primary urban core forming part of Ottawa-Gatineau, and Greater Sudbury currently has six distinct population centres (Sudbury, Capreol, Dowling, Lively, Onaping-Levack and Valley East).
