US imposes 50% tariffs on Canadian goods as trade deal collapses

The clock struck midnight on Friday, and with it, a trade negotiation that had consumed both capitals for weeks simply ended. US Trade Representative Jamieson Greer stood before reporters and delivered the news: Canada had walked away from the deal. Fifty percent tariffs on Canadian goods were now in effect as of 12:01 a.m. Eastern time Saturday morning. The collapse came not from a fundamental disagreement about trade philosophy, but from something more immediate and bitter—last-minute changes to terms that had supposedly already been settled.

Canadian Prime Minister Mark Carney had made the call to suspend negotiations late Friday, citing what he described as unfair and economically damaging revisions to the agreement that Washington had proposed in the final hours. The move was a gamble, a decision to reject a deal rather than accept what Carney characterized as a moving target. "Last-minute changes in the U.S. proposed terms were unfair, uneconomic, and called into question the reliability of any deal," he said. It was a statement that carried weight beyond the immediate dispute—a signal that Canada was questioning whether any agreement with the Trump administration could be trusted to hold.

The stakes for Canada are substantial. The United States absorbs roughly seventy percent of Canadian exports, a dependency that leaves Ottawa acutely vulnerable to tariff escalation. The deal that fell apart would have reduced American duties on Canadian vehicles from twenty-five percent to fifteen percent and cut steel and aluminum tariffs in half, bringing them to twenty-five percent. Those reductions mattered. Their loss meant real economic pain ahead.

Carney promised immediate retaliation, pledging that Canada would match American tariffs "dollar for dollar." It was a declaration of resolve, but also an acknowledgment of the bind Canada now faced. The country had already imposed its own retaliatory measures—a boycott on American alcohol that had been in place since the previous year as punishment for earlier Trump tariffs. Now those measures would deepen, and new ones would follow.

The final hours before the deadline had been frantic. Dominic LeBlanc, Canada's trade minister, had told reporters late Friday that work was still ongoing, that negotiators would push until the very last minute. "Our job is not finished," he said. But the job was finished. The Americans had changed the terms, and Canada had decided the new terms were unacceptable.

Back home, Carney faced a political challenge that extended beyond Washington. A Leger poll released Wednesday showed that fifty-six percent of Canadians wanted their government to "take a hard line" and refuse further concessions. The provincial premiers—leaders of Canada's ten provinces—held significant leverage over any deal, particularly Quebec and Manitoba. Quebec Premier Christine Frechette said she would wait to assess the agreement before committing to a position. Manitoba Premier Wab Kinew was more direct, telling reporters that Canada should continue to "fight." Carney had been trying to convince major provinces to lift their boycott on American alcohol, a symbolic but meaningful gesture of reconciliation. That effort was now dead.

What had begun as a race against the clock—both sides scrambling to reach agreement before tariffs took effect—had ended in collapse. The question now was whether the breakdown was temporary, a negotiating tactic that would lead to resumed talks, or something more fundamental. The tariffs were real. The retaliation would be real. And the damage to cross-border commerce would begin immediately.
