Mark Carney, a central banker turned politician, steps into his role at a crucial moment as President Trump sets his sights on Canada’s sovereignty and keeps threatening more tariffs.

Ex-central banker Mark Carney was sworn in as prime minister of Canada on Friday and immediately said he could work with U.S. President Donald Trump, who is promising tariffs that could devastate the Canadian economy.

Mark Carney is a newcomer to elected politics, with decades of experience in finance. After his landslide victory, he pledged to continue tariffs on the U.S. "until the Americans show us respect."
