Mark Carney was sworn in as Canada’s 24th Prime Minister on Friday, along with a leaner team of cabinet ministers who will manage the country during a U.S. trade war and a federal election campaign expected to begin by next Sunday.

“We’re ready to get to work,” Mr. Carney said on his way into the ceremony at Rideau Hall.

François-Philippe Champagne was promoted from Innovation Minister to Finance, taking over from Dominic LeBlanc, who becomes Minister of International Trade and Intergovernmental Affairs, with special responsibility for U.S. affairs. Both men will work together on trade negotiations with the Trump administration, along with Foreign Affairs Minister Mélanie Joly, who adds International Development to her duties.
