Trump's 50% dairy tariff stalls Canadian exports, threatens farm viability
Canadian dairy farmers face potential income loss and forced herd reductions; consumers may experience higher dairy prices as supply chains adjust.
Cows aren't like a tap; you can't just turn them on or off.
Mark
Why does a 50 percent tariff hit dairy farmers harder than, say, manufacturers who might absorb the cost or shift production?
Mimi
Milk is perishable and collected on a fixed schedule. A factory can slow production or find new buyers over weeks. A dairy farmer's cows produce milk every day, whether there's a buyer or not. If a processor loses US sales, they need less milk from the provincial pool, and suddenly every farmer in that pool feels it.
Luke
But the source says "some had been sold across the border." How much of Canadian dairy actually went to the US? The numbers show Canada imported way more US dairy than it exported.
Mimi
That's true—the trade deficit grew significantly after CUSMA. But even a smaller export market matters when you can't redirect the product. A processor losing even 10 or 15 percent of their US sales still needs to cut milk purchases from farmers.
Mark
What happens if farmers can't sell their milk?
Mimi
In the worst case, they dump it. Or they reduce the herd. But that's not reversible—if you sell off cows, it takes years to rebuild.
Luke
The source mentions that Canada's supply-management system is criticized as protectionist. Is Trump's complaint actually justified?
Mimi
Canadian producers say the US already has substantial tariff-free access under CUSMA that it hasn't fully used. But the trade data does show US dairy imports to Canada more than doubled since 2020.
Mark
So both sides have a point?
Luke
Both sides have numbers they can point to. What we don't know yet is whether Canadian farmers can find new markets fast enough, or whether consumers will absorb higher prices. The economist quoted says there will be "pain in the near term," but we don't know how long the near term is.
Mimi
And that uncertainty itself is destabilizing. Farmers can't plan. Processors don't know what to do. It's not just the tariff—it's not knowing when or if it ends.
Mark
Could a deal happen soon?
Luke
The economist thinks so, within months. But that's a prediction, not a fact. For now, milk is piling up with nowhere to go.
Le Pouls
- A 50% US tariff imposed on August 22 has effectively shut Canadian dairy out of the American market, eliminating export revenue that processors and farmers had long depended upon.
- Unlike manufactured goods, raw milk cannot be warehoused or rerouted overnight — cows produce on a fixed biological schedule, and the entire provincial pool system means one processor's loss cascades across hundreds of farms.
- Farmers now face the grim arithmetic of either dumping surplus milk or culling herds, decisions that are costly, irreversible, and deeply demoralizing for agricultural communities.
- Canada struck back on September 8 with retaliatory tariffs of its own, including a 50% levy on American milk and cream, but economists warn these measures raise costs for Canadian consumers and slow broader economic growth.
- Trade officials are urging affected companies to seek new markets, yet geography and perishability make distant buyers a slow and uncertain remedy for a crisis measured in days, not months.
Since August 22, a 50 percent American tariff on Canadian dairy has quietly severed a trade relationship that both nations long took for granted, leaving farmers like Casey Pruim of Abbotsford, British Columbia, caught between cows that cannot stop producing and markets that have suddenly closed. Milk, unlike steel or lumber, does not wait for diplomats — it must move, be processed, and find a buyer within days, making this particular trade disruption one of unusual biological urgency. What unfolds now in the barns of British Columbia is a small but telling parable about the fragility of systems built on the assumption that tomorrow will resemble yesterday.
Every other day, 28,000 litres of raw milk leave Casey Pruim's farm in Abbotsford, British Columbia. His 330 cows are milked three times daily, their output flowing into a system built on a simple assumption: the milk will find a buyer. That assumption cracked on August 22, when a 50 percent US tariff on $20 billion in Canadian goods — dairy included — came into effect, and American sales largely stopped.
Pruim chairs the British Columbia Dairy Association, representing some 400 farmers across the province. He does not sell directly to exporters; instead, his milk enters a provincial pool that allocates supply to processors based on their demand. When a processor loses access to the US market, it needs less milk, and the impact ripples backward through every farm in the pool. The vulnerability is compounded by milk's nature: perishable, collected on a rigid schedule, impossible to redirect overnight. "Cows aren't like a tap; you can't just turn them on or off," Pruim said. If processor demand tightens enough, farmers face a stark choice — dump the milk or reduce the herd.
The trade dispute carries an ironic backdrop. Since CUSMA took effect in 2020, the flow of dairy has moved decisively in America's favor. Canadian exports to the US grew modestly from $173 million to $220.7 million by 2025, while US dairy imports into Canada more than doubled to $968.5 million. The Trump administration nonetheless frames Canada's supply-management system as protectionist, while Canadian producers argue the existing agreement already grants Washington substantial tariff-free access it has not fully used.
Bryan Yu, chief economist at Central 1 credit union, said the shock is difficult to absorb precisely because replacement buyers cannot be found quickly. "You really can't quickly adjust to a 50 percent tariff," he told Al Jazeera, noting that thin margins leave most producers with little room to maneuver. Canada responded on September 8 with retaliatory tariffs covering $20 billion in US goods, including a 50 percent levy on American milk and cream. Prime Minister Mark Carney framed the move as both retaliation and a push toward greater economic resilience. But Oxford Economics cautioned that Canada's own tariffs would raise costs for producers and consumers alike, weakening growth across the country.
Yu predicted a deal could emerge within months, but warned the interim would bring higher prices, weaker economic activity, and deeper mistrust. For Pruim, the uncertainty itself is the wound. "It's disappointing to have these trade talks collapse again," he said — a quiet statement from a man whose livelihood depends on a system that was never designed to absorb this kind of disruption.
Every other day, 28,000 litres of raw milk leave Casey Pruim's farm in Abbotsford, British Columbia. His 330 cows are milked three times daily, their output flowing into a distribution system that has operated for decades on a simple assumption: the milk will find a buyer. Most stays in Canada. Some crossed the border into the United States, until August 22, when a 50 percent tariff on $20 billion in Canadian goods—including dairy—came into effect. Those American sales have largely stopped.
Pruim chairs the British Columbia Dairy Association, which represents about 400 dairy farmers across the province. He does not decide which of his products get exported. Instead, he sells into a provincial milk-marketing system that allocates his output to processors based on their demand. When a processor loses access to the US market because a 50 percent tariff has priced them out, that processor needs less milk. The impact ripples backward through the entire provincial pool, affecting every farmer in it. "If the processor who's exporting some of his product to the United States can no longer sell into that market because he's now priced out of the market with a 50 percent tariff, that's how it would impact the dairy farm," Pruim explained.
The vulnerability lies in milk's nature. It is perishable, collected on a rigid schedule, and dependent on processors whose demand can shift far faster than farmers can adjust production. If processor demand tightens enough, farmers face a grim choice: dump the milk or reduce the herd. "Cows aren't like a tap; you can't just turn them on or off," Pruim said. Dylan Kruger, director of public affairs at BC Dairy, acknowledged that considerable uncertainty remains about the tariffs' full impact and whether milk no longer destined for the US could find buyers elsewhere quickly enough to offset losses.
Canada's dairy trade with the United States has operated under the CUSMA agreement since July 2020. Canada manages its dairy supply through a national system of production quotas and import controls designed to give farmers more stable, predictable prices. The Trump administration argues this system restricts American dairy exports. Trump posted on Truth Social that Canada had been "ripping off the United States of America for years" with "ridiculously high tariffs." Canadian producers counter that the existing agreement already grants US imports substantial tariff-free access that Washington has not fully utilized. The numbers tell a different story about the trade relationship's direction. In 2020, Canada exported $173 million in dairy products to the US while importing $462.7 million. By 2025, Canadian exports had risen to $220.7 million, but US dairy imports into Canada had more than than doubled to $968.5 million, accounting for 13.8 percent of total US dairy exports.
Bryan Yu, chief economist at Central 1 credit union, said the immediate shock of losing a major market is difficult for Canadian producers to absorb because replacement buyers cannot be found quickly. "There is going to be pain in the near term for a lot of our producers," he told Al Jazeera. "You really can't quickly adjust to a 50 percent tariff, because it's uncharted waters for a lot of industries … and ultimately it shuts [Canadian producers] out, because a lot of them don't have the margins that they can play with." Canadian consumers might absorb some additional supply while exporters search for new markets, but neither adjustment happens overnight. Geography matters for perishable goods that once moved quickly across the border and cannot be redirected to distant markets without new buyers, logistics arrangements, and regulatory approvals.
Canada imposed retaliatory tariffs on September 8, covering $20 billion worth of US products, including a 50 percent tariff on milk, cream, and whey products and a 25 percent tariff on many cheeses. Prime Minister Mark Carney framed the response as both retaliation and an attempt to build greater economic resilience, saying Canada would match Washington's tariffs "dollar for dollar." But retaliatory measures carry their own risks. Oxford Economics warned that Canada's new tariffs would help some industries but hurt most and weaken economic growth across the country by raising costs for producers and consumers.
Ottawa's Trade Commissioner Service is advising affected companies to check their CUSMA compliance, explore available relief, and contact trade commissioners about potential new markets. Yu predicted that the US and Canada could reach a tariff deal within months, but said the interim period could bring "higher prices, weaker economic activity and deeper mistrust." For Pruim, the uncertainty itself is as destabilizing as the tariff threat. "I think, like for any Canadian, it's disappointing to have these trade talks collapse again and just the uncertainty around it."
