Canada is divided into ten provinces and three territories.
Each province has a unique system of local government which may include upper-tier or rural jurisdictions such as counties, municipal districts, regional municipalities, regional districts or regional county municipalities, and lower-tier or urban jurisdictions such as cities, towns, villages, townships, and parishes. Cities in Quebec are further subdivided into arrondissements ("boroughs").
Statistics Canada aggregates statistical census data into census divisions, which follow boundaries of one or more large local government units. Municipalities (and in some cases, communities within municipalities) within census divisions may be considered census subdivisions.
