The following list indicates ridings represented by Canadian Prime Ministers during their term(s) of office.

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.
The Senate of Canada is the upper house of the Parliament of Canada, along with the House of Commons and the Monarch. The Senate is modelled after the British House of Lords and consists of 105 members appointed by the Governor General on the advice of the Prime Minister. Seats are assigned on a regional basis: four regions—defined as Ontario, Quebec, the Maritime provinces, and the Western provinces—each receive 24 seats, with the remaining portions of the country—Newfoundland and Labrador receiving 6 seats and the three northern territories each assigned the remaining one seat. Senators may serve until they reach the age of 75.
The House of Commons is a component of the Parliament of Canada, along with the Sovereign and the Senate. The House of Commons currently meets in a temporary Commons chamber in the West Block of the parliament buildings on Parliament Hill in Ottawa, while the Centre Block, which houses the traditional Commons chamber, undergoes a ten-year renovation.
