Canada announced retaliatory tariffs of 15 to 50 percent on $27 billion of U.S. imports covering over 700 products, effective September 8, escalating a dispute that now spans steel, aluminum, appliances, farming equipment, paper and electronics. The measures answer Washington's 50 percent duties on roughly $20 billion of Canadian goods imposed Saturday.
Finance Minister François-Philippe Champagne said Canada will support workers and industry "for as long as it takes," while Industry Minister Melanie Joly rejected Trump's suggestion to rename Lake Ontario. President Trump acknowledged U.S. reliance on Canadian aluminum but threatened 50 percent tariffs on steel and autos next year, and posted that a deal was near before talks collapsed.
The affected goods represent a fraction of the roughly $800 billion in annual bilateral commerce and a nearly $50 billion U.S. trade deficit. U.S. Trade Representative Jamieson Greer characterized the Canadian levies as 5 percent of imports from Canada and 0.06 percent of U.S. consumption, but Michigan manufacturers report immediate cost increases and lost clients.
Prime Minister Mark Carney frames the conflict as a defense of sovereignty against annexation threats, while $2.5 billion in goods cross the border daily. Trump claimed a deal was in final stages and delayed tariffs for three days; The Hill and PBS report Canada announced retaliation Tuesday after negotiations collapsed, with duties taking effect September 8.
