Canada’s governing Liberals are set to choose a replacement for Prime Minister Justin Trudeau. TORONTO — Canada's governing Liberals will announce a replacement for Prime Minister Justin Trudeau on Sunday as the country deals with U.S. President Donald Trump's tariff threats and as a federal election looms.

Mark Carney has been elected leader of Canada’s Liberal Party in a months-long, high stakes race to replace Justin Trudeau.

The episode has not only given Trudeau a bump in support, but it’s delivered a potential lifeline to his flailing Liberal Party ahead of the expected election. It’s also a boon for his successor, Mark Carney, who was elected Liberal leader on Sunday and will soon take the prime minister’s office, at least briefly.
