Mark Carney was sworn in as Canada’s 24th prime minister Friday in the middle of a trade war and with an election battle on the way.

To win the next election, the new prime minister must quickly prove he is Canada’s best hope of managing relations with the White House. On Friday, Carney introduced his new Cabinet built to go head-to-head with President Donald Trump’s administration, as Ottawa lawmakers navigate the fallout of the president’s protectionist policies that one way or another will reshape Canada’s economy.

Canada‘s Liberal Party will select a new leader to replace Justin Trudeau on Sunday night, with that candidate likely to become the next prime minister of Canada, who will have to face the latest sovereignty and tariff threats from the Trump administration.

Trudeau, who served a decade as prime minister and 12 years as leader of the Liberals, announced in January he would resign from office. His departure from leadership opened up a competitive race between the top two candidates: Mark Carney and Chrystia Freeland.

Canada's Liberal Party has selected banking executive Mark Carney as its new leader, who will take over from Prime Minister Justin Trudeau and handle trade and tariff talks with President Donald Trump at least until Canada's next general election later this year.

Newsweek reached out to the White House on Sunday evening by email for comment.

Why It Matters

Trudeau announced his resignation following turmoil in his party over his response to his handling of the nation's budget.

Canada selected a new prime minister-elect on Sunday night, as Justin Trudeau's reign nears a close amid a trade war with the United States.

Canada's Liberal Party announced that Mark Carney was chosen to succeed Trudeau after party members voted in a nominating contest between four candidates.

In his acceptance speech, Carney addressed U.S. President Donald Trump's tariffs on Canada and the threat Trump has posed towards the country, calling the current events the "greatest crisis of our lifetimes."
