A census agglomeration (CA) is a census geographic unit in Canada determined by Statistics Canada. A CA comprises one or more adjacent census subdivisions that has a core population of 10,000 or greater. It is eligible for classification as a census metropolitan area (CMA) once it reaches a population of 100,000 so long as its core population is 50,000 or greater.
At the 2021 Census of Population, Canada had 111 CAs, down from 117 in 2016. Canada's largest CA by population is Chatham at 104,316, while its smallest by population is Elliot Lake at 11,372. The country's largest CA by land area is Wood Buffalo at , while its smallest by land area is Ingersoll at .
2021 changes Statistics Canada's review of CMAs and CAs for the 2021 Census of Population resulted in the addition of five new CAs, the demotion of two CAs, and the promotion of six CAs to CMAs.
