U.S. Puts a Big New Tax on Things From Canada

WASHINGTON — The United States began charging a 50% tariff on some Canadian goods early Saturday. A tariff is a tax a country puts on things brought in from somewhere else. The new tax covers about $20 billion of what Canada sells us, roughly one out of every twenty dollars' worth. Trade talks fell apart Friday night. The U.S. trade office said Canada backed out of a deal both sides had agreed to earlier in the week. Canadian leaders do not tell it that way. Prime Minister Mark Carney said Canada will match the tax dollar for dollar. He also promised help within days for Canadian workers who lose their jobs.

Why it matters: Stores here pay the tax at the border, so some groceries and building supplies could get more expensive.

WASHINGTON — The United States imposed 50% tariffs on more than $20 billion in Canadian goods after midnight Saturday, hours after trade negotiations between the two governments broke down. The measures cover roughly 5% of what Canada ships south, and they sit on top of tariffs already in place on steel, lumber and automobiles. U.S. Trade Representative Jamieson Greer said Canada had declined to finalize a deal under terms both sides agreed to earlier in the week, citing new demands and what he called walk-backs of earlier commitments. Canadian officials have not accepted that description of events. Prime Minister Mark Carney said the two governments made important progress but fell short of what Canada needed, and he pledged to retaliate dollar for dollar. He said support for affected workers and companies would be announced within days. One mechanical point gets lost in the headlines. A tariff is collected from the importer, not from the exporting country. American firms buying Canadian goods pay the 50% at the border and then decide how much of it to pass to their customers. How much of it reaches shelf prices depends on whether those buyers can find substitutes, which is why the composition of the $20 billion matters more than the headline rate does. President Trump had sounded optimistic about a deal as late as Friday, which suggests the breakdown came quickly. Neither government has said whether talks will resume.

Background

This is the latest turn in a trade fight Trump reopened with Canada in early 2025. Each cycle has run the same course: a deadline, a near-deal, a collapse, matching retaliation, and eventually a partial rollback. Canada sends roughly three-quarters of its exports to the United States, which hands Washington the stronger hand in a tariff exchange. It also makes Canadian domestic politics unforgiving of anything that looks like capitulation, which is part of why these rounds keep ending this way.

Why it matters: Escalation is cheap to announce and expensive to unwind. Both governments now have to defend a position taken in public before either has counted what it costs at home.

What to watch: Carney said Canada's retaliation list is coming within days. Watch which American exports it names. The choice is usually political, aimed at states whose representatives can pressure the White House.
