Trump's 50% tariffs on Canadian goods take effect after trade deal collapses

The tariffs arrived at midnight. At 12:01 a.m. Eastern time on Saturday, President Trump's 50% levies on Canadian goods became law, covering dozens of products—hockey sticks, wine, whiskey, vodka, dairy, honey, molasses. The move came after six days of negotiation that ended not with agreement but with mutual accusation and a Canadian announcement, delivered late Friday night by Prime Minister Mark Carney, that the talks were suspended.

Carney blamed last-minute shifts in the American position, calling them unfair and economically unsound. The U.S. Trade Representative Jamieson Greer countered that Canada had introduced new demands and walked back earlier commitments, and that the country continued to maintain what he described as outright prohibitions on certain American goods and services. Each side claimed the other had broken faith. The tariffs, targeting roughly $28 billion in Canadian exports, would be met dollar for dollar with Canadian retaliation.

Just days earlier, Trump had sounded optimistic. He announced a preliminary deal had been reached, claiming a breakthrough significant enough to warrant delaying the tariffs. He spoke of a "very good conversation" with Carney and promised that tariffs on American agricultural goods would be "non-existent"—that farmers who had been paying "tremendous tariffs" into Canada would see those duties "totally eviscerated down to zero." The U.S. trade office outlined what it said would be comprehensive market access for American goods, economic security commitments, and digital trade alignment. Trump even floated the possibility of reviving the Keystone XL Pipeline, the project Biden had canceled in 2021 amid environmental opposition.

None of it held. The tariffs now in effect are broad but not total. Oil, gas, and potash—major Canadian exports—were exempted. The levies apply only to a fraction of total U.S. imports from Canada. But the list of affected goods reads like a catalog of everyday items: dairy products, honey, whey protein, molasses, whiskey, vodka. The tariffs are unusual in another way: they apply even to goods that comply with the United States-Mexico-Canada Agreement, the free trade deal that has governed North American commerce for decades.

Trump invoked Section 338 of the Tariff Act of 1930 to impose these levies. The statute allows a president to enact duties up to 50% against countries found to have discriminated against the United States in their treatment of other nations. It has never been used before. An economist at UBS noted the absence of judicial precedent, meaning the legal ground beneath this action is untested. The move comes weeks after Trump imposed sweeping tariffs on 60 trade partners, including the European Union, part of a broader effort to reconstruct tariff regimes that the Supreme Court had struck down earlier in the year.

The collapse of the Canada talks is the latest chapter in an on-again, off-again trade dispute that began when Trump took office and announced tariffs early in his second term. The pattern has repeated: negotiation, optimism, breakdown, retaliation. What remains unclear is whether this moment represents a final rupture or another temporary pause before the cycle resumes. The tariffs are now in effect. Canada has promised to match them. And the legal precedent, untested and unprecedented, is now being written into the record.
