A constituency is a geographically defined area in which voters elect a representative (or representatives, in a multi-member constituency) to a legislative body such as a parliament. Constituencies are also known as electoral districts.

There are currently 338 parliamentary constituencies in Canada, each of which has one representative who sits in the House of Commons as a Member of Parliament. Constituency boundaries are reviewed at regular intervals by independent electoral boundaries commissions in each of the provinces. These Commissions recommend boundary changes as a result of a population change or changes in local government boundaries. The process is also called redistribution. The recommended changes must then be agreed upon by both Houses of Parliament.
