Canada and the US Couldn't Make a Trade Deal. Here's What's Going On.

Canadian Prime Minister Mark Carney announced late Friday night that Canada and the United States would not be reaching a trade deal. He accused American negotiators of making "last-minute changes" he called "unfair" and "uneconomic" (BBC).

The two countries had been talking on and off for more than a year. The US had set a deadline: make a deal or face new tariffs. Tariffs are essentially taxes that a country charges on goods coming in from abroad. If the US puts a tariff on Canadian products, those products become more expensive for American buyers.

US negotiators said the problem was on Canada's side. They claimed Canada had introduced "new demands and walk backs" — meaning Canada changed its position on things it had already agreed to earlier in the week (BBC). Both sides blamed each other, and neither walked away with a deal.

In a Saturday speech to Canadians, Carney said the collapse was "certainly not good news" for the North American free trade pact (BBC). That pact is called the USMCA, and it sets the rules for trade between the US, Canada, and Mexico. Canada and Mexico had asked to keep it going for another 16 years, but the US said no to renewing it as-is (BBC).

Carney said Canada would fight back against new US tariffs that affect $20 billion worth of Canadian exports (New York Times). In a statement from August 21, he said Canada would keep its "flexibility, independence, and sovereignty" (PMO).

Here is how the timeline unfolded. On July 20, the US said it planned to slap a 50% tariff on many Canadian goods (PMO). On August 18, Trump paused those tariffs, and Carney said there was still "important work still to be done" before the deadline (Reuters). Three days later, the talks were dead.

The bigger picture here is that Canada has been preparing for something like this. For months, Carney's government has been signing trade deals with other countries so Canada doesn't have to depend so heavily on the US. In October 2025, Canada signed a free trade deal with Ecuador that cuts or removes tariffs on most Canadian exports (PMO). He confirmed the deal was done at a meeting of Asia-Pacific leaders on November 1 (PMO). In January 2026, Canada announced a preliminary trade agreement with China to lower trade barriers (PMO). Trade between Canada and the European Union has also grown by more than 60% since a deal called CETA was signed, according to a government release from March 2025 (PMO).

This wasn't a last-minute plan. Carney said back in August 2025 that Canada should focus on trade and security partnerships that protect its independence (PMO). At a global economic forum in January 2026, he said countries need to "buy insurance and increase options" to protect themselves (PMO). He also spoke out against tariffs on Greenland and called for focused talks. Before presenting his budget in October, he noted that Canada's overall trade had grown by over 400% even as tariffs on autos, steel, and lumber loomed (PMO).

The key question now is whether the USMCA can survive its mandatory review without Canada and the US reaching an understanding. The US rejected Canada's request for a 16-year extension. Without a new deal, the rules governing about two-thirds of Canadian trade are in limbo. Carney's promise to retaliate against $20 billion in exports shows Ottawa is ready to push back rather than give in.

It's still not clear whether the "last-minute changes" Carney complained about were a real shift by the US or a pressure tactic to squeeze concessions out of Canada under the threat of a 50% tariff. Both sides are accusing the other of bad faith, which leaves little room for either to save face. Mexico, the third country in the USMCA, is caught in the middle — its own position aligned with Canada's, but the standoff between Ottawa and Washington makes its path forward harder.

Canada now has trade deals spreading across Ecuador, China, and the EU. That gives it options it didn't have before. Whether those options are strong enough to hold up against a 50% tariff wall from its biggest trading partner is the question that will shape the weeks ahead.
