US Expands Canada Trade Fight With Import Bans on Alcohol, Whey, Motorcycles

The trade dispute between the United States and Canada has entered a new phase. Washington has announced sweeping import bans on a range of Canadian goods, including most alcoholic beverages, whey products, and motorcycles with larger engines. The prohibitions are scheduled to take effect on September 29.

These bans come on top of existing 50% tariffs that the US had already placed on roughly $20 billion worth of Canadian goods. That figure represents about 5% of the $381.92 billion in products Canada exported to the US last year. The new measures are seen as an attempt to intensify economic pressure on Canadian businesses.

Trade experts note that import bans are a highly unusual tool in modern trade policy. One professor of international business described them as an extreme measure, though their overall material impact may be limited outside of specific sectors like alcohol. The move appears to be a direct response to earlier Canadian actions, where provincial liquor boards began removing American labels from shelves, effectively banning US alcohol from parts of the Canadian market.

The alcohol ban is particularly significant. It covers malt beer, certain wines, and spirits such as bourbon, whisky, gin, and vodka. In 2023, sales of Canadian whisky in the US reached 17.5 million cases, generating approximately $2.3 billion in revenue for distillers. Overall, the US imported about $846.1 million of the products now on the ban list in 2025.

The dairy restrictions target whey, a cheese-making byproduct used to add protein to food products. Demand for protein-enriched goods has surged, leading to shortages and record prices for food-grade whey. Nearly half of the $73.6 million in whey the US imported in 2025 came from Canada, though the ban covers a smaller subset of those products.

The list also includes certain molasses products and motorcycles with larger engines. While these vehicles make up most motorcycles imported from Canada, they represent less than 9% of the total US motorcycle import market.

Not all changes were restrictive. Some products, including cement, toilet paper, bedsheets, and fishing rods, have been removed from the tariff list. This follows pressure from political figures, including a Republican senator from Maine who warned the levies could jeopardize local companies and jobs.

Legal experts warn that these latest actions risk provoking further retaliation from Canada. The measures are expected to reduce consumer choice and disrupt established supply chains, with little benefit to economic efficiency or affordability.
