Ottawa, Aug. 22, 2026: A trade agreement that Canada said had appeared within reach has instead given way to a new round of tariff retaliation, with the United States moving ahead with 50% duties on a range of Canadian goods and Prime Minister Mark Carney announcing that Canada will respond dollar-for-dollar.
Carney said Saturday that negotiations had made important progress in recent weeks and that Ottawa believed earlier this week that a mutually beneficial agreement was possible, but that new U.S. terms introduced in the final days made a deal unacceptable to Canada.
Carney said Canada had spent more than a year negotiating a comprehensive agreement aimed at preserving tariff-free access for most Canadian businesses, reducing U.S. tariffs on strategic Canadian industries and providing greater certainty for businesses and workers. He said Ottawa had offered to remove its remaining retaliatory tariffs on strategic sectors, particularly steel, aluminum and automobiles, if Washington substantially reduced its own duties.
For over a year, Canada has worked intensively and in good faith with the United States to negotiate a new comprehensive trade deal. We have been pragmatic, patient, and persistent. Our goal has always been to get the best deal for Canadians, never a deal at any price or on any…

The Canadian prime minister said the two sides had made significant progress toward a possible agreement that would have improved Canada's position in the U.S. market and secured better terms for key strategic sectors. He said the United States subsequently proposed terms that Canada considered uneconomic and unfair, undermining the expected benefits and reliability of any eventual agreement.
The U.S. administration has defended the tariffs on different grounds. The White House said in its July proclamations that the additional 50% duties were intended to offset what it described as unreasonable and unequal Canadian restrictions on U.S. commerce, including measures affecting American dairy products, alcoholic beverages and motor vehicles. The proclamations authorised the duties under Section 338 of the Tariff Act of 1930.
Tonight, Canada declined to finalize the trade deal under the terms agreed earlier this week.

Despite the U.S. offer to Canada to receive the best treatment of any major exporter to our market, new demands and walk backs of other commitments by Canada have upended the careful…
The latest escalation followed a temporary postponement of the tariffs while negotiations continued. Carney said on Aug. 18 that Washington had agreed to delay implementation of the 50% Section 338 tariffs until the end of Aug. 21 because substantial progress had been made in the talks. Canada's Aug. 21 statement then said Ottawa had suspended negotiations after concluding that last-minute changes to U.S. proposals were unfair and uneconomic.
The confrontation is part of a broader dispute that began in early 2025. The White House said on Feb. 1, 2025, that it was imposing additional tariffs on Canadian imports under emergency powers, citing the flow of fentanyl and illegal immigration across the northern border. Canada subsequently responded with its own tariff measures, while the dispute later expanded into broader arguments over market access and Canadian treatment of U.S. products.
The latest U.S. measures affect a range of Canadian products, while the White House says the duties are intended to counter Canadian restrictions on U.S. commerce. Carney said Canada's negotiating objective had been to prevent the new duties from taking effect while securing stable access to the U.S. market.
Carney announced Saturday that Canada would match Washington's new tariffs dollar-for-dollar. He said the Canadian measures would focus on steel, dairy, appliances, agricultural equipment, pulp and paper and electronics, with details to be released in the coming days and the new tariffs taking effect on Sept. 8.
The scale of the bilateral relationship makes the escalation significant for both economies. Carney said Americans bought almost US$600 billion in goods and services from Canada in 2025, while Canada was the largest customer for U.S.-built automobiles and the largest customer for U.S. goods in 26 states. He also said Canada supplied 99% of U.S. natural-gas imports, 85% of electricity imports and 60% of crude-oil imports.
Carney said tariffs would raise costs and reduce choice for Canadians, while the White House says its duties are intended to expand opportunities for U.S. producers and support domestic production, investment and employment. The White House's tariff proclamations specifically identify those objectives as part of the rationale for the measures.
The dispute could also affect Canadians who live in Canada but cross the border to work in U.S. cities, from the Vancouver–Seattle corridor to Windsor–Detroit and other border communities. Canada's Employment Insurance guidance recognises people who live on one side of the border and regularly commute to work on the other as cross-border commuters, while Statistics Canada says the wider Canadian economy has significant employment exposure to U.S. export demand.
Canada is responding not only with tariffs but also with a broader diversification strategy. Carney said Ottawa had concluded more than 20 trade and security agreements across five continents during the past year and that Canadian businesses now have preferential access to 1.5 billion consumers, with further efforts planned involving ASEAN and India.
Statistics Canada estimated that 1.9 million Canadian workers, or 9.3% of total employment, were in industries dependent on U.S. demand for Canadian exports in 2024, with particularly high exposure in natural resources and manufacturing. The agency said the figure illustrates the scale of Canada's labour-market exposure to changes in U.S. demand and trade policy.
The Canadian government has also committed substantial support to businesses and workers affected by the trade dispute. Carney said nearly C$25 billion had already been provided over the previous 18 months, including support for small and medium-sized businesses, large employers and industries seeking to retool and enter international markets.
For Washington, the White House says the tariff policy is intended to change Canadian trade practices and expand opportunities for American producers. Its July proclamations state that the measures are designed to counter restrictions that Washington says disadvantage U.S. commerce and to encourage American production, investment and employment.
The immediate result is a sharp deterioration in a trade relationship that, according to Canada's prime minister, had appeared capable of producing a new agreement only days earlier. Canada has suspended the negotiations and announced dollar-for-dollar retaliation from Sept. 8, while Washington has proceeded with the new 50% duties; the next stage will test whether the measures deepen into a longer restructuring of North American trade or bring the two governments back to negotiations.
