Canada’s dairy sector faces severe supply disruptions and financial uncertainty after the United States implemented a 50 percent tariff on $20bn in Canadian goods, forcing producers like Abbotsford dairy farmer Casey Pruim to confront potential milk dumping and herd reductions as cross-border trade stalls.
Cross-Border Tariffs Threaten Canadian Dairy Supply Chains
Raw milk leaves Casey Pruim’s Abbotsford farm every second day at a volume of 28,000 litres, entering a provincial distribution network that relies on steady processor demand. According to Pruim, who chairs the British Columbia Dairy Association representing roughly 400 regional dairy farmers, those distribution channels have largely stalled since US President Donald Trump’s 50 percent tariff on Canadian dairy and other goods took effect on August 22. Producers do not export independently; instead, farms sell into a provincial pool that supplies processors making goods for both domestic consumption and the US market. When processors lose American buyers due to prohibitive pricing, reduced demand flows backward into the provincial supply pool. Dylan Kruger, director of public affairs at BC Dairy, told Al Jazeera that considerable uncertainty remains regarding whether surplus milk can find alternative buyers to mitigate financial losses.
Perishable Milk Production Creates High Vulnerability
Dairy farming carries unique structural vulnerabilities during trade disputes because milk is highly perishable and collected on rigorous schedules. Pruim, whose Prime Acres Ltd farm houses 330 cows milked three times daily, explained that if processor demand drops, farmers face the stark reality of dumping milk or culling herds. “Cows aren’t like a tap; you can’t just turn them on or off,” Pruim told Al Jazeera. Bryan Yu, chief economist at Central 1 credit union, noted that producers lack the profit margins to absorb sudden trade shocks. “You really can’t quickly adjust to a 50 percent tariff, because it’s uncharted waters for a lot of industries,” Yu told Al Jazeera, adding that while domestic consumers might absorb some extra supply temporarily, finding new global markets takes time.
Did you know? Canada manages dairy production through a national supply management policy using quotas and import controls to stabilize domestic prices. Critics call it a protectionist cartel, while Canadian producers point out that existing trade pacts grant substantial, underutilized access to US imports.
Trade Imbalances and Retaliatory Measures Escalate Tensions
Trade friction between Ottawa and Washington centers on differing views of the United States-Mexico-Canada Agreement (CUSMA). Washington argues that Canada’s supply management system restricts American dairy exports, with Trump posting on Truth Social that Canada had been “ripping off the United States of America for years.” Conversely, Canadian producers note that the dairy trade deficit with the US has grown significantly since CUSMA came into force in July 2020. Data from the Dairy Processors Association of Canada shows Canadian dairy exports to the US rose from 241.3 million Canadian dollars ($173m) in 2020 to 308.7 million Canadian dollars ($220.7m) in 2025, while US dairy imports into Canada more than doubled from 647.4 million Canadian dollars ($462.7m) to 1.355 billion Canadian dollars ($968.5m).
Frequently Asked Questions
Why did the United States impose tariffs on Canadian dairy?
