On September 8, 2026, the day Canada's retaliatory tariffs took effect, Trump signed orders banning a slate of Canadian imports starting September 29, including whey products, molasses, non-alcoholic beer and alcoholic drinks from malt beer and wine to whiskies and vodka, along with larger motorcycles. Senior administration officials called it a direct response to Canada's retaliatory tariffs, and U.S. Trade Representative Jamieson Greer called the moves a “natural consequence of Canada's continued discriminatory treatment of crucial American exports.” The bans escalate the trade war that began with Trump's 50 percent tariffs on most Canadian goods in July (see Trump Slaps 50 Percent Tariffs on Most Canadian Goods Over Alcohol, Dairy, and Auto Disputes).
The import bans took effect at 12:01 a.m. on September 29. The alcohol ban rests on Proclamation 11061, issued under Section 338 of the Tariff Act of 1930, which allows a president to bar imports from a country that discriminates against U.S. commerce; companion proclamations cover dairy products and motor vehicles. Jacob Jensen of the center-right American Action Forum put the value of the banned goods at $967 million on 2025 figures, 87 percent of it alcohol. Whisky and liqueurs in containers larger than four liters are exempt, CNN reported. Inu Manak of the Peterson Institute: “Using import bans against an ally is unprecedented and a major deviation from US trade policy.” In the Oval Office the day before, Trump said of Canada, “They're gonna come in and they're gonna say, 'Sir, we are sorry,'” and, “They've treated the United States very, very badly. I think a deal will be made but it's gonna be fair.” U.S. Trade Representative Jamieson Greer: “But there's no urgency on our side.” The same day, White House trade adviser Peter Navarro warned Canada against what he called election interference (see Navarro Warns Canada It Will 'Pay Even More Dearly' if It Interferes in the Midterms, and Tells Its Lobbyists to 'Get the Hell Out').
