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."

Toronto's main stock index opened higher on Friday ahead of Mark Carney's appointment as prime minister of Canada, while still being set for a weekly loss amid growth concerns from an ongoing trade war.
