Canadian Prime Minister Mark Carney said his country would “never” yield to the United States as he declared victory in federal elections early Tuesday, following a campaign overshadowed by relentless provocations and steep trade tariffs imposed by US President Donald Trump.

The election was dominated by Mr. Trump and his relentless focus on Canada. Pierre Poilievre, the opposition leader, lost the seat he had held for 20 years.

Canada’s Liberal Party is projected to win a fourth consecutive election, giving a mandate to former central banker Mark Carney after a campaign in which he pledged to boost economic growth and stand up to US President Donald Trump in a trade war.
