TORONTO (AP) — Canadian Prime Minister Mark Carney is expected to trigger the process for an early parliamentary election this weekend for an expected vote on April 28. The election will take place against the backdrop of a trade war and sovereignty threats from U.S. President Donald Trump.

Justin Trudeau has officially stepped down as the Prime Minister of Canada. Trudeau resigned on Friday after nearly a decade in power. He had announced his resignation in January, as polls indicated that his Liberal Party was likely to face defeat in the upcoming election.
