Canada currently uses 34 area codes which are assigned to specific geographic areas plus area code 600 which is not assigned to a geographic area. Three provinces which use only one area code are New Brunswick, Newfoundland and Labrador, and Saskatchewan. Several other locations share an area code such as Nova Scotia and Prince Edward Island which use area code 902, as well as, Yukon, Northwest Territories and Nunavut which use area code 867. The province using the most area codes is Ontario which is using thirteen area codes followed by Quebec which is using seven area codes.

Although area codes in Canada are not assigned based upon population, the locations with greater populations have an increased demand for area codes. The non-geographic Canadian area code 600 is reserved for services such as data links, mobile satellite services and ISDN. Three new area codes are assigned but not yet implemented.
