Census Metropolitan Area (CMA)

Description

Census Metropolitan Area (CMA) and Census Agglomeration Boundary Files portray the boundaries of the census metropolitan areas and census agglomerations for which census data are disseminated. Census metropolitan areas and census agglomerations consist of one or more adjacent municipalities (census subdivisions) around a core. To form a census metropolitan area, the core must have a population of at least 50,000 and the entire census metropolitan area must have a total population of at least 100,000. To form a census agglomeration, the core must have a population of at least 10,000. The files contain the boundaries of all census metropolitan areas and census agglomerations defined for the census. Census metropolitan areas and census agglomerations crossing provincial boundaries appear in the boundary files in provincial parts.
