WASHINGTON — President Donald Trump on Tuesday, Sept. 8, 2026, signed proclamations excluding certain Canadian dairy products, alcoholic beverages, and motor vehicles from importation into the United States, escalating the trade fight as Ottawa’s retaliatory tariffs took effect. The White House said the bans apply to goods imported on or after 12:01 a.m. eastern time on Sept. 29, 2026.

In the alcohol proclamation, Trump found as fact that Canada is “discriminating” against the commerce of the United States — citing provincial bans on U.S. alcoholic beverages that do not similarly restrict products from other countries — and pointed to prior 50 percent additional ad valorem duties under section 338 of the Tariff Act of 1930. Sibling proclamations the same day extend the import-exclusion approach to dairy and motor vehicles. Goods already subject to the 50 percent duties that were imported but not yet entered before Sept. 29 remain under that duty rate, the proclamations say.

The White House alcohol text also cites Saskatchewan’s Aug. 27 announcement of an additional 50 percent levy on U.S. alcoholic beverages, effective Sept. 8, 2026, as evidence Canada maintained or increased the discrimination after the earlier duties took effect. Canada’s retaliatory package — covering roughly $20 billion in U.S. goods at rates of 15%, 25%, or 50% — took effect around midnight Tuesday, according to The Guardian (Associated Press) and BBC News.

Trump also directed the General Services Administration to treat Canadian products as ineligible for certain large, long-term U.S. government contracts until Canada allows “full and fair reciprocity” for American products, the Guardian/AP reported. Canadian Prime Minister Mark Carney framed Ottawa’s response as reducing dependence on a single partner: “It’s about ensuring that no country can hold us hostage. And that we can live how we want to live.”

Trade barriers of this scale concentrate presidential tariff and exclusion power in a bilateral relationship long treated as open. Whatever the politics on either side of the border, the practical effect for importers, retailers, and drinkers is a harder wall — bans layered on top of 50 percent duties — with three weeks until the Sept. 29 effective date.
