An electoral district in Canada is a geographical constituency upon which Canada's representative democracy is based. It is officially known in Canadian French as a circonscription but frequently called a comté ('county'). In Canadian English it is also colloquially, and more commonly known as a riding or constituency.
Each federal electoral district returns one Member of Parliament (MP) to the House of Commons of Canada; each provincial or territorial electoral district returns one representative—called, depending on the province or territory, Member of the Legislative Assembly (MLA), Member of the National Assembly (MNA), Member of Provincial Parliament (MPP) or Member of the House of Assembly (MHA)—to the provincial or territorial legislature.
