Canadian opposition leader Pierre Poilievre urged Prime Minister Mark Carney to reconvene Parliament as trade tensions with the United States intensify. Poilievre said Canadians need answers about the collapse of trade talks, the cost of tariffs and protections for jobs. Carney removed Canadian negotiators from U.S. trade discussions on Friday and said Canada would impose retaliatory tariffs (countermeasures against another country’s tariffs) starting Sept. 8, matching Washington’s new 50 percent tariffs dollar for dollar. The dispute comes after tensions escalated during President Trump’s second term, despite the countries’ longstanding alliance.
