Premiership of Mark Carney

The premiership of Mark Carney began on March 14, 2025, when the first Cabinet headed by Mark Carney was sworn in by Governor General Mary Simon. Carney was invited to form the 30th Canadian Ministry and become the 24th Prime Minister of Canada after he succeeded Prime Minister Justin Trudeau as leader of the Liberal Party in the 2025 leadership election. Shortly after taking office, Carney advised the governor general to dissolve Parliament and trigger the 2025 federal election, where he led his Liberals to win a plurality of seats in the House of Commons of Canada, forming a minority government.

Upon taking the oath of office, Carney became the first Canadian prime minister born in any of its territories (as opposed to provinces) and the third born west of Ontario (after Joe Clark and Kim Campbell). He is the second prime minister to have earned a PhD, after William Lyon Mackenzie King. Additionally, he is the first to have never served in prior elected office, and the first since John Turner not to be sitting in the House of Commons at time of appointment. In his first act as prime minister, Carney signed a prime ministerial directive to end the consumer carbon tax by April 1, while ensuring that April's carbon rebate continues. The directive was affirmed by an order in council signed by Governor General Mary Simon. Carney's first foreign visits were to France and the United Kingdom on March 17 to strengthen mutual security and sovereignty. The 2025 Speech from the Throne was delivered by King Charles III as part of his 2025 royal tour of Canada, outlining the government's first priorities following the election.

Carney's appointment occurred against the backdrop of Donald Trump's victory in the 2024 United States presidential election and his threats to impose sweeping tariffs on Canada and even annex it. This period coincided with a dramatic turnaround in the Liberal Party's fortunes: the party had been more than 20 points behind in the polls when Trudeau announced his resignation, but soon after Carney was sworn in as prime minister, the polling gap had been eliminated altogether and the Liberals were in the lead, putting them in striking distance of a majority government. The scale of their political turnaround was described by analysts as having "little precedent" in Canadian history.
