If you buy a bottle of Canadian whisky, a wedge of Canadian cheese, or a car built in Ontario, the importer bringing it across the border has been paying an extra 50 cents on every dollar of that item’s value since August 22. That cost does not stay with the importer. It works its way into the price on the shelf and the sticker on the lot, and it is still being collected today.
Why Canada Got Hit With a 50 Percent Duty
The duty traces to three separate proclamations President Trump signed on July 20, 2026, each invoking Section 338 of the Tariff Act of 1930, a rarely used law that lets a president impose extra duties on a country found to be discriminating against U.S. commerce. Proclamation 11046 targeted Canadian treatment of American alcoholic beverages: since March 2025, every Canadian province and territory has blocked provincial liquor boards from purchasing, distributing, or retailing U.S. alcohol, and only Alberta and Saskatchewan later lifted the ban. The proclamation states that U.S. alcoholic beverage exports to Canada fell from about $718 million to about $137 million, an 81 percent drop, while exports from countries like Chile, Japan and the European Union to Canada rose over the same period. That is the discrimination finding the White House cited to justify singling out Canadian imports rather than acting against every trading partner at once.
Proclamation 11047 made the same finding for dairy, pointing to Canada’s tariff-rate quota system on U.S. cheese, and Proclamation 11048 made it for motor vehicles, citing Canada’s auto tariff scheme. All three set an additional ad valorem duty of 50 percent on the covered Canadian goods, the maximum Section 338 allows, and all three were originally scheduled to take effect August 19, 2026. A duty at that rate is not a minor line item: on a $40 import, it adds $20 before the item ever reaches a U.S. shelf or dealer lot.

The Three-Day Delay That Pushed the Start to August 22
Before the duties ever took effect, the administration pushed the date back. Proclamation 11056, signed August 18 and published in the Federal Register on August 24, is titled a “temporary suspension,” but read the operative text and it does something narrower: it delays the effective date in all three proclamations from August 19 to 12:01 a.m. eastern on August 22, 2026. The proclamation says senior officials reported that Canada “expressed a commitment to remove the discriminations” at issue, and that a short pause served the public interest while those talks continued. It amended the annex of each underlying proclamation to swap in the new date. It did not cancel the duties or extend the pause past those three days, and it did not touch the 50 percent rate itself.
That distinction matters for anyone reading the headline “temporary suspension” and assuming the tariff went away. It did not. The word “suspension” in the title describes the three-day gap between the original August 19 start date and the new one, not an ongoing pause in collection. Once August 22 arrived, the duties took effect exactly as the three underlying proclamations describe, and they have applied every day since.
A search of the Federal Register for any later Canada-duty action, through the date this article was verified, turns up nothing beyond that August 24 notice. No repeal, no further suspension, and no new effective-date change has been published. Unless a household is watching for a formal Federal Register notice, there is no public sign the 50 percent rate is going away.
Cheese and Other Dairy Imports Carry the Same Rate
Proclamation 11047 covers Canadian dairy products, with cheese as the highest-profile item for grocery shoppers. The 50 percent duty applies on top of whatever base tariff already existed on that product, so an importer bringing in Canadian cheese now owes the U.S. Customs and Border Protection agency half again the item’s declared value, before it ever reaches a distributor. Grocers and specialty cheese shops sourcing from Canadian producers are the ones absorbing that bill first, and they typically pass some or all of it forward rather than shrink their margin.
Vehicles Built in Canada Cost More to Import
Proclamation 11048 applies the same 50 percent rate to motor vehicles caught by Canada’s tariff scheme. Several U.S. brands assemble specific models in Ontario, meaning a duty aimed at Canada can still land on a badge a shopper would call American. A dealership importing a Canadian-built vehicle pays the duty at the border, and that cost is built into the price tag before a customer ever sees the car, the same way a shelf price already reflects whatever an importer paid to bring a product into the country.
Who Pays First, and What a Later Refund Would Look Like
Section 338 duties are collected at the border from the importer of record, not the Canadian producer and not the U.S. buyer directly. But an import duty is a cost of getting the product to market, and businesses generally build it into what they charge, which is how a border-level policy ends up changing a number on a receipt or a loan document. Proclamation 11056 does address one scenario households should know about: if a future action requires U.S. Customs and Border Protection to refund duties already collected, the proclamation says those refunds “shall be processed pursuant to applicable law and CBP’s standard procedures.” As of today, no such refund action has been published, and the duty is doing what Section 338 says it does, whichever direction that number moves next: it will be modified through a formal Federal Register notice from Customs and Border Protection, not a press statement.
For now, the record is straightforward: three Section 338 proclamations imposed a 50 percent ad valorem duty on Canadian alcoholic beverages, dairy, and motor vehicles; a fourth proclamation moved the start date from August 19 to August 22, 2026; and no later Federal Register document has suspended, reduced, or repealed it.
