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.

OTTAWA, Ontario (AP) — New Canadian Prime Minister Mark Carney is heading to Paris and London on Monday to seek alliances as he deals with U.S. President Donald Trump’s attacks on Canada’s sovereignty and economy. Carney is purposely making his first foreign trip to the capital cities of the two countries that shaped Canada’s early existence.

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.
