The move represents an about-face for Canada, which had been one of the few countries to punch back against President Trump’s protectionist agenda.

Prime Minister Mark Carney’s decision to remove many tariffs on imports from the US comes after a series of warnings from businesses and analysts that the levies were inflicting economic damage on Canada.

The sitting legislator stepped down to allow Poilievre to run in his seat, thereby allowing him to return to the House of Commons.

Carney said Canada will include the carve-out that the US has on Canadian goods under the 2020 free trade deal that shields the vast majority of goods from the punishing duties.
