The
Census Metropolitan Areas / Census Agglomerations Cartographic
Boundary File for Canada contains the boundaries of all 27 Census
Metropolitan Areas and 113 Census Agglomerations for the 2001
Census. A census metropolitan area (CMA) or a census
agglomeration (CA) is formed by one or more adjacent
municipalities centred on a large urban area (known as the urban
core). The census population count of the urban core is at least
10,000 to form a census agglomeration and at least 100,000 to
form a census metropolitan area. To be included in census metropolitan
areas and census agglomerations, other adjacent municipalities
must have a high degree of integration with the central urban
area, as measured by commuting flows derived from census place
of work data.
The Census Metropolitan Area and Census Agglomerations Boundary
File consists of polygons representing the census metropolitan
areas and census agglomerations. Every polygon encoded as part
of land area comprised of census metropolitan area and census
agglomeration has a CMAuid (a code to uniquely identify census
metropolitan areas and census agglomerations) associated with
it. The Census Metropolitan Area and Census Agglomerations Boundary
File is available at the national level only. The national Census
Metropolitan Area and Census Agglomerations Boundary File consists
of polygons representing 140 census metropolitan areas and census
agglomerations. There are more polygons than census metropolitan
areas and census agglomerations primarily because of the additional
polygons needed to represent islands.
