A US ban on some Canadian imports takes effect, barring dairy products including whey

September 29, 2026

A US ban on some Canadian imports is now in force, covering dairy products such as whey and, by one think tank estimate, $967 million of goods.

Canada is a longtime US ally and trading partner, and since Trump returned to the White House last year it has faced a series of his tariffs alongside an older dispute over Canadian dairy quotas.

Key facts

AP News reports that the United States now keeps some Canadian goods out, among them dairy products such as whey, a byproduct of milk, and The Guardian carries the same account. Jacob Jensen, who directs trade policy at the American Action Forum, a center-right think tank, puts the goods affected at $967 million of Canadian imports, working from 2025 figures. AP News expects the economic effect to stay small, and it reports Patrick Childress pointing out that every barred product already faced tariffs from Trump.

AP News places the ban in a longer run of measures. Since Trump went back to the White House last year, one tariff after another has left the outlook for trade across the region uncertain, and this step pushes his second-term trade fight with a longtime ally a notch further. “This marks yet another escalation in the trade war that may result in further retaliation on the Canadian side,” said Jensen. AP News also reports that Trump is openly trying to move Canadian manufacturing south, and that the two countries have argued for years over the steep tariffs Canada charges on dairy imports above a quota. “There is now a price to be paid for access to the United States market,” said Carney, according to AP News.

CNN and CNBC carry Trump's prediction that the other side will soon ask to end the tariffs. “Over the next three or four weeks, they’re going to come to us and they’re going to say, ‘We’re going to get rid of all the tariffs,’” Trump said. The Hill's headline has Trump describing Canada as among the worst countries anywhere. The accounts agree on the ban and what it covers, and no outlet contradicts another; the Canadian reply has not yet been reported.

“Over the next three or four weeks, they’re going to come to us and they’re going to say, ‘We’re going to get rid of all the tariffs,’” said Trump.

Still developing

Trump said Canada is going to come to the US to get rid of all the tariffs, which stands as the last development at the time of this draft.
