Numbered highways in Canada

Numbered highways in Canada are split by province, and a majority are maintained by their province or territory transportation department. With few exceptions, all highways in Canada are numbered. Nonetheless, every province has a number of highways that 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.
