Trade negotiations between the United States and Canada broke down late Friday, triggering 50% U.S. tariffs on roughly $20 billion worth of Canadian goods and prompting Canadian Prime Minister Mark Carney to declare his country is “at war” economically with its largest trading partner.
The tariffs took effect just after midnight Friday into Saturday, August 22, after last-minute talks collapsed. U.S. Trade Representative Jamieson Greer said Canada “declined to finalize the trade deal” and came back with “new demands and walk backs” despite what he called an American offer of “the best treatment of any major exporter.” The new duties hit a range of Canadian products, including dairy, alcoholic beverages, cement and hockey equipment.
Carney rejected the U.S. characterization of how talks fell apart. “You’re at war when you get attacked. We got attacked,” he told reporters at a Saturday press conference, arguing that Washington had introduced unfair, last-minute changes that undermined the reliability of any deal. “Canada has what the world wants,” Carney said. “And we will not allow any nation to determine our future.”
Canada has announced it will respond with matching, dollar-for-dollar tariffs beginning September 8, targeting American steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics — an attempt to mirror the economic pain on industries and states that export heavily to Canada.
The dispute escalated further this weekend when Trump threatened an additional round of 50% tariffs on Canadian cars, trucks, auto parts and steel, this time set to take effect January 1, 2027, unless a deal is reached. Trump urged automakers to shift production to the United States, promising “ZERO TARIFFS” for companies that manufacture domestically. He accused Canada of imposing steep tariffs on American farmers and blamed the imbalance for what he described as a $60 billion U.S. trade deficit with Canada, writing that the current arrangement is “not sustainable, and NOT ANYMORE!”
The latest tariffs follow months of on-and-off negotiations. U.S. steel and aluminum tariffs on Canada had already doubled to 50% back in June, and the two countries pledged at the G7 summit in June to reach a broader deal within 30 days — a timeline that slipped after Washington briefly suspended talks in late June before restarting them at month’s end.
U.S. officials have downplayed the near-term economic impact on the American side. Greer noted the newly tariffed goods represent roughly 5% of overall Canadian trade and just 0.06% of total U.S. consumption, though he acknowledged the effect “may be different” for Canada, which sends the large majority of its exports south of the border.
Economists on both sides of the border are watching how the dispute filters through to consumers. Tariffs on dairy, alcohol and construction materials like cement are likely to show up in retail prices in both countries, while a prolonged standoff over autos and steel — industries deeply intertwined across the two countries’ supply chains — could raise vehicle prices and squeeze manufacturers in the U.S. Midwest and Ontario alike if it drags into 2027.
No new talks have been publicly scheduled between the two governments as of this weekend.
