List of prime ministers of Canada by constituency

The following list indicates ridings represented by Canadian Prime Ministers during their term(s) of office. It should be noted that some Prime Ministers represented more than one consituency during their term(s), hence the tallied numbers exceed the number of Prime Ministers. Moreover, one Prime Minister - Sir Mackenzie Bowell - served his term while a member of the Senate, although he had previously been a member of the House of Commons from Ontario.

Three provinces - New Brunswick, Newfoundland and Labrador, and Prince Edward Island - have not been represented by a sitting Prime Minister. Mackenzie King briefly represented the Prince Edward Island riding of Prince; and Jean Chretien even more briefly represented the New Brunswick riding of Beausèjour prior to their assuming the premiership. None of the three territories have been represented by a person who served as Prime Minister.

It is interesting to note that two ridings have been represented by two sitting Prime Ministers. Prince Albert was served by King and Diefenbaker; and Quebec East was represented by Laurier and St. Laurent. Calgary West was represented by Bennett during his term, and by Harper prior to his. Similarly, Macdonald served his fourth term as MP for Carleton, a riding represented by Borden as Opposition Leader in the 10th Parliament.
