The first national census of Canada was taken in 1871, as required by section 8 of the then "British North America Act, 1867" (now the "Constitution Act, 1867"). Parliament implemented the requirements of the constitution through the "Census Act" of May 12, 1870. All inhabitants of Canada were surveyed, including Indigenous peoples. While this was the first national census, only the four provinces that were part of the Dominion of Canada at the time—Ontario, Quebec, New Brunswick and Nova Scotia—were included in the census. Other areas that would later become part of Canada continued to be enumerated with their own separate censuses. The results of the 1871 Census were reported in a five-volume set in 1873, in both English and French.
