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.

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."

Former central bank chief Mark Carney was sworn in as Canada’s prime minister on Friday, taking over at what he has called “a time of great peril” as the country faces a trade war with the United States and annexation threats from President Trump.
