I’ve recently completed a major project over on the Wikipedia: I put together articles on the electoral history of every Canadian prime minister. Here’s the links for all you election junkies. Feel free to ask me any questions
Electoral history of Sir John A. Macdonald - Canada’s first PM and third longest serving; non-consecutive terms; tied with Laurier for back-to-back majority governments (four each); died in office in 1891 just months after winning the general election of 1891.
Electoral history of Alexander Mackenzie- became prime minister by defeating Macdonald on a non-confidence motion, then won the election, and four years later, lost to Macdonald.
Electoral history of Sir John Abbott - became PM when Macdonald died; never contested a general election as PM; one of two PMs who sat in the Senate, not the Commons; retired due to ill health.
Electoral history of Sir John Thompson - became PM when Abbott retired; died at a garden party at Windsor Castle before he had a chance to lead his party in a general election.
Electoral history of Sir Mackenzie Bowell - third successor to Macdonald; sat in the Senate; lost the premiership to a Cabinet revolt before he could lead the party in a general election.
Electoral history of Sir Charles Tupper - fourth successor to Macdonald; became PM when the Cabinet lost confidence in Bowell (a Cabinet revolt organized by Tupper’s son Charles Hibber Tupper, who was also a Cabinet minister…). Tupper père finally led the Conservatives in a general election at the expiry of the 1891 Parliament, and lost to Laurier. Never sat in Parliament as Prime Minister. Shortest term of any Prime Minister: 66 days.
Electoral history of Sir Wilfrid Laurier - defeated Tupper; first francophone PM; tied with Macdonald for four back-to-back majorities; 15 years in office uninterrupted, the longest term in office of any Canadian PM; fourth-longest term in office, after King, Macdonald and Trudeau.
Electoral history of Sir Robert Borden - Canada’s leader in the Great War; put together a coalition of Conservatives and Liberals, but few francophones; single term of 8 years, two general elections.
Electoral history of Arthur Meighen - lost all three general elections he contested, but still became prime minister twice (and you thought the Electoral College produced odd results … )
Electoral history of William Lyon Mackenzie King - Canada’s longest serving PM - 21 years in total, in three non-consecutive terms; traded the premiership back and forth with Meighen over a constitutional crisis and then with Bennett during the Depression; won six out of seven general elections, a Canadian record.
Electoral history of R. B. Bennett - had the misfortune to win election just as the Depression was started; summarily turfed out five years later in favour of King.
Electoral history of Louis St. Laurent - second francophone PM; two solid majorities, then lost a minority to Diefenbaker.
Electoral history of John Diefenbaker - the perennial candidate; won a municipal election at age 25, then lost every election he contested for the next 20 years; lost at the federal, provincial and municipal levels, before gaining a seat in the federal Parliament; eventually won three of five general elections: won a minority, then the largest majority government ever at that point, then a minority, then lost to Pearson. Stayed in Parliament for another 15 years, dying in office as a Member of Parliament
Electoral history of Lester B. Pearson - lost to Diefenbaker in two general elections, then won two minority governments against Diefenbaker; although he never had a majority, he implemented universal medicare, a new flag and the Canada Pension Plan.
Electoral history of Pierre Trudeau - third-longest time in office, after King and Macdonald, and ahead of Laurier, but never won back-to-back majorities; served two non-consecutive terms, being defeated by Clark in 1979, and then defeating Clark in 1980.
Electoral history of Joe Clark - defeated Trudeau; won a minority government; announced he would govern as if he had a majority; didn’t work; fourth-shortest term in office (9 months).
Electoral history of John Turner - Trudeau’s successor; never won a general election, losing two general elections to Mulroney; 79 days in office, the second-shortest time in office after Tupper; never sat in Parliament as PM.
Electoral history of Brian Mulroney - first Conservative to win back-to-back majorities since Macdonald. In the process destroyed support for the Conservative Party, as his successor discovered…
Electoral history of Kim Campbell - Mulroney’s successor; took the Conservatives from a majority in the Commons to two seats, the worst melt-down of a national party in the Commonwealth; 132 days in office, the third-shortest time; never sat in Parliament as PM.
Electoral history of Jean Chrétien - first PM to win three back-to-back majorities since Laurier. Retired after party taken over by his successor, Paul Martin.
Electoral history of Paul Martin - pushed Chrétien out, and promptly took the Liberals from majority, to minority, to Opposition.
Electoral history of Stephen Harper - leader of the new Conservative Party; longest serving conservative PM since Macdonald.
Electoral history of Justin Trudeau - good hair gets you elected with a majority.
