: US-Canada Trade Talks Collapse, 50% Tariffs Trigger Retaliation
Tap title to read story
U.S.-Canada trade talks collapsed late Friday, allowing 50% U.S. tariffs on roughly $20 billion of Canadian goods to take effect at 12:01 a.m. Eastern time Saturday. Prime Minister Mark Carney suspended negotiations and recalled Canadian negotiators, saying last-minute U.S. terms were unfair, uneconomic and threatened Canadian sovereignty. U.S. Trade Representative Jamieson Greer said Canada instead rejected terms previously agreed, including proposed tariff reductions for steel, aluminum, automobiles and lumber. The White House says the duties rely on Section 338 of the 1930 Tariff Act and cover specified Canadian imports. Canada plans dollar-for-dollar retaliation beginning September 8, targeting U.S. steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics. The dispute threatens further damage to highly integrated North American supply chains and complicates the future of the USMCA. No new bilateral negotiations are scheduled, according to Greer. President Donald Trump criticized Canada Sunday, indicating tensions remained unresolved after the tariff escalation.
