President Donald Trump has threatened to double tariffs on Canadian cars, trucks and auto parts from 25% to 50% — just days after formal US-Canada trade negotiations collapsed. Canada says it will retaliate “dollar for dollar.”
What Trump announced
Trump said Monday that he would raise tariffs on Canadian automobiles and auto parts from 25% to 50%, effective January 1. The threat came hours after talks broke down late Friday, moments before a US-imposed deadline triggered a 50% levy on nearly $20 billion of Canadian imports, according to BBC News.
Both sides blame each other. Canadian officials say Washington introduced last-minute demands that were unacceptable — including a clause restricting which countries Canada could sign future trade deals with. US Trade Representative Jamieson Greer counters that Canada changed its position at the last minute. “They wanted more,” Greer told CNBC.
Canada promises to hit back
Prime Minister Mark Carney called the threat unsurprising and accused Trump of wanting to destroy Canada’s auto industry. He said Canada would respond with reciprocal tariffs on American goods “dollar for dollar,” and signalled talks would resume only if the US returned with the “right attitude.”
Ontario Premier Doug Ford — whose province hosts most of Canada’s car manufacturing — told Trump to “kiss my ass” and suggested charging the US more for oil, gas, electricity and critical minerals. Trump hit back on Truth Social, accusing Ford of “bluster” and warning that “the consequences for Canada will be far WORSE.”
Canada also announced C$11 billion in funding to build six icebreakers at a Quebec shipyard, part of a wider push to diversify away from dependence on the United States.
Timeline: how the dispute escalated
| Late Friday (Aug 21) | Trade talks collapse; a US deadline triggers a 50% levy on nearly $20 billion of Canadian imports. |
| Monday (Aug 24) | Trump threatens to raise auto tariffs from 25% to 50%. |
| September 8 | Canada’s announced retaliatory tariffs are scheduled to take effect. |
| January 1 | The threatened 50% auto tariffs would take effect. |
What’s at stake for both economies
Canada supplies about 60% of total US crude oil imports and close to 100% of US natural gas exports, according to Canadian government data. Businesses on both sides of the border warn the tariff war will hurt ordinary consumers, with Canadian-made goods sold in US stores expected to rise sharply in price if the new levies take hold.
The dispute is also raising fresh questions about the future of the USMCA, the trade pact underpinning $1.6 trillion in North American trade. Canada and Mexico want it extended; Washington says it will not renew the deal in its current form.
What happens next
Canadian government leaders were set to hold a news conference Tuesday to outline how the country plans to protect workers and businesses. With neither side showing signs of backing down, analysts expect the standoff to intensify before any return to the negotiating table.
