Tariff War Imperils Canada's Dairy Sector

When Trade Turns to Tension

It's not just politics that are in flux—dairy farmers across western Canada are feeling the immediate impact of a trade war that has been brewing for months. As US President Donald Trump's tariffs took effect on August 22, Canadian dairy exports to the United States have come to a grinding halt. This is not merely a financial shock; it's a crisis that threatens the livelihoods of thousands of farmers and their families.

Casey Pruim, owner of Prime Acres Ltd. in Abbotsford, British Columbia, represents one such face of this struggle. His farm houses 330 cows, each milked three times daily, contributing to a daily output of nearly 14,000 litres of raw milk. Yet, as US tariffs surge, his milk can no longer reach its traditional destination—making it a logistical nightmare with no quick fix.

"Cows aren't like a tap; you can't just turn them on or off," Pruim warned, highlighting the fundamental contradiction between dairy farming and sudden market shifts.

The Fragility of Supply Chains

The Canadian dairy industry operates under a system known as supply management—a framework that has long protected farmers from volatile global markets by regulating production quotas and import controls. While this structure ensures stability, it also creates vulnerabilities when international trade is disrupted.

Under CUSMA (Canada-US-Mexico Agreement), Canada and the US have historically shared relatively open dairy trade. However, recent tensions have seen a dramatic shift in that balance. Canadian dairy exports to the US grew from $173 million in 2020 to over $220 million in 2025, while imports more than doubled to nearly $968 million—showing just how reliant Canada is on its neighbor.

With tariffs now imposed at a staggering 50 percent on Canadian dairy exports, the entire system begins to unravel. As Dylan Kruger of BC Dairy puts it, "there is still considerable uncertainty around the impact of the US tariffs." And for dairy producers like Pruim, uncertainty means risk, and risk means financial strain.

Stale Milk, Stagnant Farms

It's not just about lost revenue; the milk itself is becoming a liability. Dairy is highly perishable, requiring strict temperature control and rapid distribution. Once milk can no longer reach its intended buyers in the US, farmers face a stark choice: dump it or reduce herd size.

This isn't theoretical—it's happening now. "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.

For producers who have invested years in building their operations, such disruptions can be catastrophic. In the worst-case scenario, entire herds must be culled, and many farmers are now left wondering whether they can survive the next few months.

Retaliation and Economic Fallout

In response to Washington's move, Canada has matched the tariffs dollar for dollar with its own retaliatory measures. The Canadian government, led by Prime Minister Mark Carney, sees this as a defensive posture designed to protect domestic industries. But while such actions may offer short-term comfort, they also carry long-term economic risks.

Oxford Economics noted that these tariffs will likely hurt most sectors, raise costs for consumers, and weaken overall economic activity. For a sector already struggling with the pressures of supply management and global competition, any added friction could prove fatal.

Bryan Yu, chief economist at Central 1 Credit Union, expressed concern over the immediate pain this situation will inflict: "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."

A Long Road Ahead

As the dust settles from this latest trade spat, one thing is clear: the path back to stability won't be easy. Farmers like Pruim are left to navigate not only immediate supply chain disruptions but also the longer-term consequences of a fractured relationship between two of North America's largest economies.

Canada's Trade Commissioner Service is offering support to affected businesses, but solutions—whether new markets or regulatory relief—require time and coordination. For now, dairy farmers are caught in a cycle of uncertainty, their futures hanging by a thread on decisions made far away in Washington, DC.

And yet, amid this turmoil, there remains a glimmer of hope. As Yu suggests, the US and Canada may still find a way to negotiate a compromise in the months ahead. But until then, farmers like Casey Pruim will continue to face the daily challenge of keeping their herds—and their businesses—alive.
