Trump's Ban on Canadian Dairy and Alcohol Kicks In Sept. 29 as U.S. Farm Groups Warn of Backfire

Since Trump signed the five proclamations Tuesday, Sept. 8, the fight over dairy has moved from tariffs to outright bans, and the people supposedly being defended by them are pushing back.

The proclamations, issued under Section 338 of the Tariff Act of 1930, ban Canadian dairy products, alcohol including beer, wine and spirits, and motorcycles from entering the U.S. starting Sept. 29, according to the White House and the Epoch Times. A separate 50% tariff on other Canadian goods, including all-terrain vehicles, motorboats and certain cheeses, takes effect Sept. 15. Trump also ordered the General Services Administration to remove Canadian-origin products from federal procurement schedules worth more than $50 billion a year, according to Breitbart.

The moves came the same day Canada's own retaliatory tariffs took effect, hitting roughly $20 billion (about CA$27.6 billion) in American goods, including a 50% tariff on U.S. dairy ingredients like whey, casein and milk proteins and a 25% tariff on U.S. cheese, according to MS NOW and Farms.com. Trump called the dynamic the "Canadian Trade Scam" in a Truth Social post, pointing to Canada's supply management system that caps dairy imports and sets domestic prices.

Why American Farmers Aren't Cheering

Canada's supply management system creates an asymmetry in a trade fight, according to Tim Gibbons, executive director of the National Family Farm Coalition. Because Canada's system insulates its farmers from foreign price swings, the fallout lands harder on U.S. producers than Canadian ones, he told MS NOW.

"U.S. farmers are trapped in a failed free trade system that works against their best interests," Gibbons said, arguing that tariff escalation offers "limited impact to Canadian dairy farmers" while doing little for American ones.

Darin Von Ruden, president of the Wisconsin Farmers Union, told MS NOW that market disruptions like this typically cut both ways against ordinary Americans: lower prices paid to farmers and higher prices charged to shoppers, with "the middleman, the multinational corporations," pocketing the difference. Wisconsin's dairy farm count has fallen from around 43,000 in 1990 to under 5,000 today, per Von Ruden, and diesel hitting close to $6 a gallon nationally this week adds another cost on top of the tariff fight.

Agriculture Department figures cited by MS NOW complicate Trump's framing that Canada is shutting out American dairy. The U.S. exported about $1.31 billion in dairy products to Canada in 2025 against $432 million in Canadian imports, a roughly $880 million surplus in America's favor. Not every U.S. dairy voice agrees with that read, though. The National Milk Producers Federation and the U.S. Dairy Export Council thanked the administration in late August for what USDEC president Krysta Harden called standing up for producers who "waited far too long for Canada to live up to its promises," according to Farms.com.

What This Costs Canada

Canada's side of the ledger is smaller in absolute terms but concentrated. Export Development Canada estimates roughly $778 million in Canadian exports could be hit by the U.S. import bans, modest against Canada's $779 billion in total 2025 exports, according to Global News. But EDC chief economist Stuart Bergman said the U.S. market accounts for 70% to 95% of total export sales for firms in the alcohol and dairy sectors, meaning firm-level pain could be severe even if the national GDP hit is small.

Canadian alcohol exports totaled $1.36 billion in 2023, with 90% going to the U.S. and two-thirds of that being spirits like rye whisky, gin and vodka, according to Global News, citing the Trade Commissioner Service. Wine Growers of Canada told Global News about $8.3 million in wine exports go to the U.S. annually.

Canadian Prime Minister Mark Carney has framed the standoff as a matter of national posture rather than pure economics. "There's always a cost to action," Carney said in a video address reported by Breitbart. "But it doesn't come close to the cost of standing still." Dairy Farmers of Canada president David Wiens said his organization "won't apologize for wanting a strong Canadian dairy sector," per Farms.com.

The China Wrinkle

David L. Cohen, who served as U.S. ambassador to Canada under President Biden, told Fox News Digital that the pressure campaign risks pushing Ottawa closer to Beijing. "I think Canada has tentatively tried to play some footsie with China that the Trump administration may not be happy with," Cohen said, adding that aggressive treatment of allies has caused "many countries to at least reevaluate whether there are additional deals that can be made with China." Vice President JD Vance has separately called Canada's posture toward China "insanity" compared to its posture toward the U.S., according to Fox News.

Trump has threatened to block sales of Bombardier, the Quebec-based aircraft maker, unless it moves manufacturing to the U.S. The threat has already drawn pushback from Kansas Republican Senators Roger Marshall and Jerry Moran, who say they've raised concerns directly with the White House over more than 1,200 Kansas jobs tied to the company. Canada's trade minister, Dominic LeBlanc, says Ottawa is still assessing the latest U.S. measures and remains in contact with U.S. Trade Representative Jamieson Greer, with no new negotiating date announced.
