List of prime ministers of Canada by constituency

The following list indicates ridings represented by Canadian prime ministers during their term(s) of office. Some prime ministers represented more than one constituency during their term(s), hence the tallied numbers exceed the number of prime ministers. Moreover, two prime ministers—John Abbott and Sir Mackenzie Bowell—served their terms while a member of the Senate. John Turner was a member of neither the House of Commons or the Senate during his entire term as Prime Minister.

Three provinces—New Brunswick, Newfoundland and Labrador, and Prince Edward Island—have never been represented by a sitting prime minister. Mackenzie King briefly represented the Prince Edward Island riding of Prince, and Jean Chrétien even more briefly represented the New Brunswick riding of Beauséjour prior to their assuming the premiership, however. None of the three territories has been represented by a person who served as prime minister.

Two ridings have been represented by two sitting prime ministers. Both King and John Diefenbaker served Prince Albert; and both Wilfrid Laurier and Louis St. Laurent represented Quebec East. R. B. Bennett represented Calgary West during his premiership, as did Stephen Harper prior to his. Similarly, John A. Macdonald served his fourth term as MP for Carleton, a riding represented by Robert Borden as Opposition Leader in the 10th Parliament.
