The Canadian government is racing to negotiate a deal with the Trump administration in order to avoid a fresh wave of U.S. tariffs set to hit many of its exports to the United States starting on Wednesday.

However, after weeks of meetings, the prospects for a deal remained uncertain Monday, and Canadian broadcaster CBC reported that the two countries were at an impasse.

Speaking to reporters, Prime Minister Mark Carney described the talks as โ€œvery delicate and intense.โ€ He also said he planned to speak with Trump before the deadline.

The new tariffs, if implemented, would hit about $20 billion worth of Canadian products imported to the U.S., including hockey sticks, some clothing, wines, some dairy products and certain building materials such as cement and plywood. Energy products, potash, fish and critical minerals are excluded from the duties.

In 2025, Canada ranked as the third-largest source of imports for the U.S., according to Census Bureau data, with more than $380 billion worth of goods crossing the border into the U.S. last year.

The White House has said the tariffs are in response to Canadaโ€™s โ€œdiscriminatory treatment of American productsโ€ and that itโ€™s โ€œleveling the playing field for crucial American exports โ€” cars, alcohol, and dairy.โ€

It plans to implement the duties under Section 338 of the Tariff Act of 1930, a 96-year-old law that authorizes the president to hit any foreign country that discriminates against U.S. commerce with tariffs of up to 50%.

No president has ever invoked Section 338 before, and legal challenges are all but certain to be filed against the tariffs.

Nonetheless, importers could pass the new tariffs down to consumers โ€” putting more pressure on Americans who are already navigating higher costs. Consumer prices have jumped 3.4% over the last year, up from 2.4% right before the Iran war.

Tariffs currently cost the average American household around $1,100 annually, Yaleโ€™s Budget Lab estimates.

A trade cold war gets hot

For more than a year, the U.S. and Canada have engaged in a trade tit for tat. The U.S. put in place global tariffs on imports including steel, aluminum and autos last year โ€” as well as IEEPA tariffs on Canada over alleged fentanyl trafficking at the northern border.

Canada denied that its border was a significant source of fentanyl smuggling into the U.S. and retaliated with tariffs of its own on American products. Now, U.S. officials say these new tariffs are payback for Canadaโ€™s retaliation.

โ€œThe policy basis for [Wednesdayโ€™s] duties are related to measures that Canada took against the United States,โ€ U.S. Trade Representative Jamieson Greer said last week. โ€œIโ€™ve got two countries in the world that have retaliated against the United States for trade measures: the Peopleโ€™s Republic of China and Canada,โ€ said Greer. โ€œThatโ€™s not the kind of company you really want to be running in.โ€

Carney, in a statement, called the threatened duties โ€œthe latest in a series of unilateral U.S. trade actionsโ€ that have been in โ€œdirect violationโ€ of the U.S.-Mexico-Canada Agreement โ€” a trade deal Trump signed during his first term.
