Mark Carney has been sworn in as Canada’s new prime minister as the nation faces Trump's trade war. 'We’re his largest client in so many industries,' Carney says.

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."

Carney, a former Goldman Sachs executive, said protecting Canadian workers and their families in the face of unjustified trade actions and growing the economy will be his top priorities.
