"Census returns are official Government of Canada records that enumerate the country’s population. [T]hey often include the age, occupation, ethnic origin, religious denomination and the place of birth for the persons listed. For each census, the records are arranged by province or territory, and then are divided into districts which usually correspond to counties and cities. Districts are typically divided into sub-districts, corresponding to townships, parishes and larger towns." (Library and Archives Canada)
