Canada’s next prime minister has helped run two Group of Seven economies in crisis before 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.

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.
