Numbered highways in Canada are split by province, and a majority are maintained by their province or territory transportation department. All highways in Canada are numbered except for three in the Northwest Territories, one in Alberta, one in Ontario, and one in Quebec. Ontario's 7000 series are not marked with their highway number but have been assigned one by the Ministry of Transportation. A number of highways in all provinces are better known locally by their name rather than their number. Some highways have additional letters added to their number: A is typically an alternate route, B is typically a business route, and other letters are used for bypass (truck) routes, connector routes, scenic routes, and spur routes. The territory of Nunavut has no highways.
