TORONTO — Canada’s next prime minister has already helped run two Group of Seven economies in crisis and now will try to steer Canada through a looming trade war brought by U.S. President Donald Trump, a threat of annexation and an expected federal election. Former central banker Mark Carney will become prime minister after the governing Liberal Party elected him its leader Sunday in a landslide vote with 85.9% support. Carney, 59, replaces Prime Minister Justin Trudeau, who announced his resignation in January but remains prime minister until his successor is sworn in in the coming days. Carney is widely expected to trigger an election the coming days or weeks amid Trump’s sweeping tariff threats. …Carney said Canada will keep its initial retaliatory tariffs in place until “the Americans show us respect.”
