U.S.-Canada Trade Talks Collapse as 50% Tariffs Begin
The United States began collecting 50% tariffs on $20 billion in Canadian imports after negotiations broke down at a midnight deadline, and Prime Minister Mark Carney pledged equal retaliation.

Trade talks between Washington and Ottawa fell apart as a midnight deadline expired, and new U.S. import taxes on Canadian goods took hold immediately afterward. The levies, set at 50%, apply to Canadian products valued at $20 billion, according to reporting from NPR and the BBC.
Negotiators from both governments were still working as the clock ran out, but they could not close the gap in time. Once the deadline passed without an agreement, the tariffs went into force without delay.
Prime Minister Mark Carney responded by committing Canada to a matching set of countermeasures. Ottawa's retaliatory levies on American products will be equal in value to what the U.S. is now charging on Canadian goods -- what Carney described as a dollar-for-dollar response. He also blamed the American side for the breakdown, saying the U.S. introduced "unfair" changes at the last minute to an agreement that, in his account, would have kept the tariffs from taking effect. The specific terms of that near-deal, and which provisions changed in the final hours, have not been detailed publicly in the available reporting.
The context
The tariffs arrived at the end of a negotiating process that ran up against a hard deadline: the two countries had until midnight to reach a deal that would have stopped the import taxes from taking effect. Per The Guardian, Carney's position is that an agreement was within reach and was undone by late alterations from the American side. The U.S. account of why the talks failed was not included in the source material, and Washington's version of the final hours remains unclear from the available reporting. What is established is the sequence: sustained negotiations, a missed deadline, immediate imposition of the 50% levies, and a same-day Canadian pledge to answer in kind. How the $20 billion in covered goods breaks down by product category was not specified in the reporting.
Why it matters
Canada is the second-largest U.S. trading partner, so a 50% tariff wall between the two economies is a structural change rather than a routine trade dispute. American importers of the affected Canadian goods now face substantially higher costs, which can flow through to consumer prices and complicate supply chains that cross the border. Canada's promised countermeasures mean U.S. exporters will face equivalent barriers going the other way. Both economies absorb the costs of a two-sided tariff exchange that took effect overnight, with no negotiated off-ramp currently in place.
What’s next
Ottawa has committed to retaliation matching the U.S. tariffs in value, though the timing and the list of targeted American products have not been announced in the available reporting. Key open questions include whether negotiations resume, whether either side adjusts the scope of its levies, and how the U.S. responds to Carney's characterization of the failed deal. Any formal statement from Washington detailing its account of the breakdown will be worth watching.
