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.

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.

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."
