Mark Carney sworn in as Canada's new prime minister as country deals with Trump's trade war

Former central banker Mark Carney was sworn in as Canada's new prime minister on Friday, and will now try to steer his country through a trade war brought by U.S. President Donald Trump, annexation threats and an expected federal election.

Carney, 59, replaces Prime Minister Justin Trudeau, who announced his resignation in January but remained in power until the Liberal Party elected a new leader. Carney is widely expected to trigger a general election in the coming days or weeks.

"We will never, ever, in any way shape or form, be part of the United States. America is not Canada," Carney said. "We are very fundamentally a different country."
