The United States is set to impose a fresh round of 50% tariffs on roughly $20–28 billion in Canadian exports at 12:01 a.m. Eastern Time on August 19, 2026, unless the two countries resolve three long-standing trade disputes. The issues are provincial bans on American alcohol, Canada's dairy import quotas, and Canadian retaliatory tariffs on U.S. automobiles. Some Canadian negotiators fear there may be no way to avert the tariffs from taking effect.
Trump invoked Section 338 of the Tariff Act of 1930 — a Depression-era statute seldom used in modern trade policy — to authorise the new levies, which cover 554 tariff lines. U.S. Trade Representative Jamieson Greer has stated that resolving all three disputes simultaneously is a condition of any deal, calling them the legal basis for the threatened tariffs.
Canada has signalled willingness to concede on all three points. According to sources familiar with the talks, Ottawa's package includes removing its retaliatory tariffs on U.S. automobiles, accepting the American interpretation of dairy tariff-rate quota allocation under the Canada–United States–Mexico Agreement (CUSMA), and ending provincial bans on American beer, wine and spirits. In return, Canada is pushing for the U.S. to drop the new 50% tariffs and provide relief on existing sectoral levies on steel, aluminum, lumber and autos. Ottawa also wants a joint announcement that CUSMA modernisation talks will resume in the autumn.
A structural problem has complicated Canada's position from the outset. Eight of Canada's ten provinces imposed partial or full bans on U.S. beer, wine and spirits beginning in March 2025, in retaliation for earlier rounds of American tariffs. The federal government cannot compel the provinces to lift those bans. That power rests with provincial liquor boards, meaning Ottawa can only persuade. Multiple provinces have said they will not remove the bans until their own tariff grievances are addressed in any deal — a commitment Ottawa cannot guarantee in advance of a final agreement.
Canada's trade team has told its American counterparts that August 19 would be a 'cliff-type moment,' warning that if the tariffs take effect there would be no political appetite among Canadians to continue negotiations. The two sides have been meeting daily in the lead-up to the deadline, but some Canadian officials believe the gap remains too wide to bridge in time.
Dairy presents its own complications. The United States has long objected to Canada's supply management system, which controls domestic dairy production and applies steep duties on imports exceeding agreed quotas. The U.S. Trade Representative's annual trade document notes above-quota tariff rates of 245% on cheese and 298% on butter, and finds that provincial liquor board practices 'greatly hamper' U.S. alcohol exports to Canada. Dairy Farmers of Canada is urging the federal government not to offer any further concessions on dairy or supply management.
Even if Ottawa and Washington reached agreement on all three issues, relief on existing tariffs is far from guaranteed. The U.S. currently imposes 50% tariffs on Canadian steel and aluminum and 25% on Canadian automobiles. U.S. negotiators have indicated those levies will not be removed entirely, limiting the relief Ottawa can offer its provinces as an incentive to lift the alcohol bans.
Canada's broader ambition, according to sources cited by CTV News, is to secure what negotiators describe as 'favoured nation' status across all sectors — not zero tariffs, but the lowest applicable rate the U.S. extends to any comparable partner. That aim forms part of a wider bilateral framework being pursued separately from CUSMA, whose formal review remains pending. Whether any such framework is achievable before August 19 remains, as of the time of writing, unresolved.
