President Donald Trump threatened Monday to raise tariffs on imported cars, trucks, auto parts and steel from Canada to 50 percent starting January 1, escalating a trade dispute that saw the US impose tariffs on Canadian goods last week after negotiations collapsed.
Trump’s Latest Threat
Writing on Truth Social, Trump said “Canada has been ripping off the United States of America for years,” adding, “On Trade, and in other ways, also, they are among the worst Nations in the World to deal with.” The threat came in response to Canadian Prime Minister Mark Carney’s announcement Friday that Canada would impose retaliatory tariffs on US goods starting September 8, after trade talks between the two countries fell apart just before a midnight deadline.
Canada is the third-largest source of US imports, with more than $380 billion worth of goods crossing the border last year. Trump’s threatened tariffs on autos, trucks, parts and steel would apply on top of the 50 percent tariffs the US began enforcing last week on roughly $20 billion of Canadian goods, including dairy products, alcohol, cement and hockey equipment.
Carney Digs In
Ontario Premier Doug Ford, whose province depends heavily on cross-border auto manufacturing, pushed back sharply on the threats, prompting Trump to respond on social media, “Someone should get these clowns to ‘fall in line’ or, the consequences for Canada will be far WORSE!” Bloomberg News reported Sunday that Carney was designing Canada’s retaliation to focus on steel, dairy, appliances, agricultural equipment, pulp, paper and electronics.
Carney, who has described the standoff as akin to being “at war” with Washington, has said Canada would match US tariffs “dollar for dollar” and criticised the Trump administration for what he called using “economic integration as a weapon.”
A Deal That Fell Apart
The breakdown followed nearly two weeks of negotiations and came just days after Trump had paused the tariffs for three days, writing on social media that the two sides “have a DEAL!” US Trade Representative Jamieson Greer said a key sticking point was Canada’s continued retaliatory measures, including provincial bans on the sale of American alcohol introduced in 2025.
The dispute also casts further doubt over the future of the USMCA trade agreement, which the Trump administration announced in July it would not renew in its current form, leaving the deal subject to a series of rolling annual reviews.
What Happens Next
With Canada’s retaliatory tariffs not set to take effect until September 8, and Trump’s threatened auto and steel tariffs targeted for January 1, both sides have a window in which talks could theoretically resume, though neither government has signalled openness to returning to the table in the immediate term.
