Former central banker Mark Carney will become prime minister after the governing Liberal Party elected him its leader Sunday in a landside vote with 85.9% support.

The 59-year-old political newcomer says he will keep tariffs on US imports "until the Americans show us respect".

Mark Carney, soon to become Canada's new prime minister, is a two-time central banker and crisis fighter about to face his biggest challenge of all: steering Canada through Donald Trump's tariffs. The Liberals announced Carney as Justin Trudeau's successor on Sunday after party members voted in a nominating contest.
