US imposes 50% tariffs on Canada as trade talks collapse; Ottawa plans retaliation

Breakdown of Washington negotiations

Trade talks between the United States and Canada collapsed overnight after three days of negotiations in Washington. Canadian Prime Minister Mark Carney suspended the discussions and recalled his negotiating team to Ottawa, stating that the United States introduced last-minute modifications to previously agreed terms. Canadian Minister of Intergovernmental Affairs and Trade Dominic LeBlanc had negotiated in Washington through late Friday evening before the White House deadline passed. Hours earlier on Friday, US President Donald Trump told reporters he expected a deal would be concluded, citing productive relations with the Canadian prime minister.

In recent weeks we have made substantial progress toward improving Canada's position as the country with the world's best agreement with the US. However, that progress was not sufficient to achieve our goals for Canadians. As a result, this evening I decided to suspend trade negotiations with the US.

US tariffs take effect under 1930 law

Following the collapse of negotiations, the United States imposed 50% tariffs on Canadian exports valued between $20 billion and $28 billion annually. The duties took effect overnight under the Tariff Act of 1930. The tariffs target consumer and industrial items, including wooden hockey sticks, cement, wine, dairy, and clothing. The targeted volume represents just over 5% of Canada's annual exports to the American market. The measures add to existing American duties on Canadian steel, aluminium, lumber, and automobiles. The White House had initially threatened the 50% tariffs in July, citing alleged Canadian discrimination against American automotive, dairy, and alcohol sectors, before issuing a three-day delay on August 18.

Opposing accounts of the dispute

Both governments presented conflicting narratives regarding the final hours of the Washington meetings. Carney described the late American terms as economically unjustified and damaging to the credibility of any agreement. United States Trade Representative Jamieson Greer stated that Canada walked back previous commitments, wasted an opportunity for an agreement, and tabled new demands concerning steel, aluminium, autos, and lumber. Draft terms discussed earlier in the week had contemplated reducing US tariffs on Canadian cars and trucks from 25% to 15%, lowering metals tariffs from 50% to 25%, and restoring American alcohol sales in Canadian liquor stores.

They worked hard, in good faith. However, changes in the proposed American terms made at the last minute were unfair, uneconomic and called into question the credibility of the agreement.

Canadian retaliation and economic measures

Canada announced it will enact dollar-for-dollar retaliatory tariffs on American goods beginning September 8, 2026, with specific product lists scheduled for release in the coming days. Carney announced an upcoming federal assistance package for domestic workers and businesses, supplementing 25 billion Canadian dollars in support delivered over the past 18 months. Carney stated that Canada is preparing nearly 500 billion Canadian dollars in infrastructure projects and maintains free trade access to 1.5 billion consumers across global markets. No further negotiating rounds are scheduled between the two governments.
