The premiership of Justin Trudeau began on November 4, 2015, when the first Cabinet headed by Justin Trudeau was sworn in by Governor General David Johnston. Trudeau was invited to form the 29th Canadian Ministry and become Prime Minister of Canada following the 2015 federal election, where Trudeau led his Liberal Party to win a majority of seats in the House of Commons of Canada, defeating the Conservative majority government of Prime Minister Stephen Harper. Trudeau's Liberals were reduced to minority governments in the federal elections of 2019 and 2021, with his party losing the national popular vote twice.
On March 14, 2025, Trudeau resigned as prime minister, being succeeded by Mark Carney.
