Western Farm Report

April 20, 2026

The July 1, 2026 CUSMA review date is no longer a background event for dairy producers. The United States Trade Representative has placed Canada’s supply management system near the top of its list of structural grievances, and the formal review process is already underway. Producers in Alberta, Saskatchewan, and Manitoba who operate under the Western Milk Pool have direct stakes in what happens next — from quota values to market expansion opportunities — and the outcome will shape the sector for at least the next decade.

The 2026 Review: What Is Actually Being Contested

The Canada-United States-Mexico Agreement includes a mandatory six-year joint review, set for July 2026. The review was designed as a forum to air grievances and assess the agreement’s performance — not an automatic trigger for renegotiation — but the current US administration is treating it as leverage. US Trade Representative Jamieson Greer has signalled the agreement’s renewal is not automatic, tying any 16-year extension to what he calls “specific and structural issues,” with dairy access named explicitly.

The core American complaint sits inside tariff-rate quotas, or TRQs. Under CUSMA, Canada committed to allow roughly 3.5 percent of its domestic dairy market to enter tariff-free from the US. The TRQs were scheduled to increase annually through 2026. Washington’s complaint is that Canada has administered these quotas in ways that limit effective US access — by allocating 85 to 100 percent of the quota to domestic dairy processors, which leaves little room for US exporters to deal directly with retailers or end buyers.

Filling rates on the US TRQs have averaged between 27 and 39 percent over the past three years. The US dairy lobby argues Canada is deliberately underfilling the quotas. Canadian officials counter that when the Canadian price of certain TRQ-subject products is pegged to US or world indexes, there is no margin incentive to import. The mechanics, not the intent, explain the low fill rates.

Separately, the US International Trade Commission launched a probe in July 2025 alleging Canada is dumping surplus non-fat dairy solids — skim milk powder and whey protein — into US markets at below-market prices. ITC findings were expected in March 2026, timed to land just before the formal CUSMA review opens. That timing gives Washington a formal legal instrument to use alongside political pressure.

Bill C-202 and Ottawa’s Locked Position

Canada’s current posture is constrained by statute. Bill C-202 received royal assent in June 2025. The legislation amends federal law to restrict the government from making trade commitments that would undermine supply management for dairy, poultry, and eggs. Prime Minister Mark Carney has publicly ruled supply management out of the negotiating conversation with Washington, calling it non-negotiable.

In practical terms, this means Ottawa cannot simply offer expanded TRQ access or structural changes to quota administration without triggering domestic legal and political consequences. Critics point out that this may reduce Canada’s flexibility in negotiations where Washington is using dairy as a wedge issue — forcing Canadian negotiators to yield in other areas, potentially including steel, aluminum, auto parts, or critical minerals, in order to protect the dairy status quo.

Whether Carney’s position holds through the full review process remains the central uncertainty. Past CUSMA negotiations under Trudeau showed that dairy concessions were ultimately unavoidable when broader trade access was at risk. The political calculus has not changed materially: Quebec and Ontario hold the majority of Canadian dairy farms and the majority of national political weight, making any compromise politically costly for a minority or slim-majority federal government.

What the Prairie Dairy Sector Looks Like Right Now

Alberta, Saskatchewan, Manitoba, and British Columbia operate under the Western Milk Pool, which coordinates quota allocation, milk pricing, and production targets among the four provinces. The western share of national dairy output sits at approximately 16 percent — a figure that has been stable for years because quota is allocated by population rather than by production efficiency or comparative advantage.

Prairie herds are larger and more productive on average than their eastern counterparts. Alberta and Saskatchewan operations average 183 to 194 cows per farm, compared to roughly 83 cows per farm in Quebec. This structural difference means western producers are generating more milk per quota unit, with better economies of scale, yet remain capped by a quota distribution formula built around population demographics rather than agricultural capacity.

In January 2025, Alberta Milk, SaskMilk, Dairy Farmers of Manitoba, and the BC Milk Marketing Board issued a two percent quota increase across the Western Milk Pool to meet continued strong demand in both fluid and industrial markets. That kind of demand-driven growth has characterized the western market over the past several years, and processing capacity in the West has been expanding to accommodate it. [Note: verify current 2026 WMP quota adjustments with Alberta Milk or SaskMilk for the most current figures.]

Quota values in the Prairie provinces reflect the absence of provincial price ceilings. In provinces such as Ontario, there are limits on what quota can trade for on the open market. Alberta, Saskatchewan, and Manitoba impose no such ceiling. Quota in these provinces has been trading in a range of $40,000 to over $56,000 per kilogram of butterfat per day, making entry or significant expansion a capital-intensive undertaking. A producer looking to add 50 cows of capacity may need to acquire $2.5 million or more in quota before touching land, buildings, or equipment costs.

Alberta Milk’s New Producer Assistance Program offers two kilograms of quota for every kilogram of purchased quota for qualifying new entrants, with approved applicants limited to three per year. It is a targeted tool for succession and new entry, not a broad market instrument. The program is a signal that the sector recognizes capital barriers to entry are real and limiting.

Farmgate Pricing: A 2.3 Percent Increase Takes Effect February 2026

The Canadian Dairy Commission’s annual pricing review, conducted in October 2025, resulted in a farmgate milk price increase of 2.3255 percent effective February 1, 2026. The National Pricing Formula that determines the adjustment weighs 50 percent of the year-over-year change in indexed production costs and 50 percent of the Consumer Price Index.

The 2026 increase reflects pressure from two directions. Feed costs and labour remained elevated through 2024, even as general inflation moderated. Canada’s CPI rose 2.4 percent in the period reviewed, while food prices tracked closer to four percent. The farmgate increase aligns with that middle ground while partially compensating for production cost pressures that are running above headline inflation for most input categories.

The combined effect of the formula result and an increase to CDC carrying charges brings the total cost increase for milk used by processors — to make cheese, yogurt, butter, and other products — to 2.375 percent, or just over two cents per litre sold to processors. The retail pass-through from farmgate changes is not regulated and will depend on what processors, distributors, and retailers layer on top.

This follows a year in which the farmgate price was slightly reduced. The 2025 adjustment reflected productivity gains and lower costs for some inputs. The two-year pattern — a modest reduction followed by a larger increase — reflects how the National Pricing Formula smooths volatility rather than immediately tracking input cost movements. Prairie producers running tight margins on feed in 2024 felt the cost pressure before the pricing formula caught up.

CUSMA Reform Scenarios and What They Mean for Prairie Producers

Analysis from multiple trade policy sources converges on a few likely outcomes for the CUSMA dairy file, none of which involves the dismantling of supply management itself. The more probable scenarios involve changes to how TRQs are administered, who holds them, and how fill rates are monitored.

One scenario is that Canada adjusts TRQ allocation to allow more quota access for US exporters to deal directly with retailers and food service buyers rather than routing all quota through domestic processors. This would address the US lobby’s stated complaint without breaching the overall tariff protection structure. Tariff walls on over-quota dairy imports — ranging up to 300 percent on some product categories — are not seriously threatened, since the US has not formally requested their elimination and the structural economics make them politically untouchable.

A second scenario involves increased TRQ volumes. Estimates suggest that even a significant increase in fill rates would translate to roughly two percent additional US market access at most within a near-term horizon. That figure captures a portion of the Canadian market’s growth rather than displacing existing domestic production — which means quota values would likely remain stable even if additional US cheese or butter enters the market under expanded TRQs. The impact falls harder on the growth trajectory for existing producers than on established production.

For Prairie producers specifically, a scenario where supply management remains intact but quota growth slows — because additional import access absorbs some of the demand expansion — is the most operationally significant outcome. The two percent WMP quota increase issued in January 2025 was tied directly to demand growth. If import access absorbs even a fraction of that future growth, quota increases will be smaller. That has implications for producers who are banking on organic quota growth to justify recent capital investments.

The longer-range argument — that any serious weakening of supply management would benefit Prairie dairy producers because production would migrate west, toward cheaper land and larger herds — is speculative and depends on political conditions that do not currently exist. Quota allocation by population is embedded in the system’s foundational agreements. A shift to efficiency-based allocation would require the consent of Quebec and Ontario producers, which is not forthcoming.

Trade Exposure and the Broader Agricultural Context

Prairie grain and oilseed producers watching the CUSMA file should note that dairy is being used as a negotiating instrument alongside other agricultural and non-agricultural issues. US grievances on dairy, softwood lumber, digital trade rules, provincial procurement practices, and aluminum and steel all sit in the same negotiating space. How Ottawa prioritizes concessions across these files will affect all Prairie producers.

CUSMA-compliant agri-food goods have so far remained exempt from the broader tariff actions Trump imposed on Canadian goods in early 2025. That exemption reflects the deep integration of North American agricultural supply chains and the fact that a broad coalition of US agricultural associations — aware of how much US grain, oilseed, and livestock production depends on Canadian inputs and markets — has consistently supported maintaining the agreement. Disrupting CUSMA on dairy could introduce risk into that broader agricultural exemption.

The USDA Foreign Agricultural Service, through its Ottawa office, regularly files dairy sector assessments that provide useful context on Canadian market conditions and US positioning. Those assessments are public and are worth reviewing directly for producers who want the US government’s current read on market access issues.

On-Farm Considerations for 2026

Against this policy backdrop, Prairie dairy producers are managing a set of concrete near-term decisions that will not wait for trade negotiations to resolve.

Feed cost management remains the dominant on-farm financial pressure. The farmgate price increase partially compensates for 2024 input inflation, but feed grain prices on the Prairies in 2025 were volatile, and carry-in stocks going into spring 2026 are variable by region. Producers building rations for the coming milk year should factor in basis risk on Prairie feed grains, particularly if they are not sourcing from their own acres or from fixed-price forward contracts.

Quota value stability is not guaranteed but is supported by the current policy environment. Bill C-202’s protection of supply management and Carney’s public commitment to defending the system provide near-term floor support for quota values. However, any credible signal from Ottawa of a willingness to negotiate structural dairy changes — a change in ambassador posture, a trade deal framework announcement, or ITC ruling that gains traction in Washington — would move quota markets. Producers carrying significant quota debt should be monitoring the political signals from Ottawa closely through the summer.

ProAction compliance timelines apply across the Western Milk Pool and continue regardless of trade policy developments. Producers working toward full on-farm food safety, traceability, and animal care requirements should treat those timelines as fixed operational commitments, not contingent on political outcomes.

For producers considering expansion, the combination of elevated quota prices, rising farmgate returns, and strong WMP demand fundamentals makes a case for cautious growth. The risk factor is that CUSMA outcomes could slow future quota growth and compress the return on newly acquired quota over a 10 to 15 year capital horizon. Any expansion business case built on continued two percent annual quota growth should include a downside scenario with quota growth at half that rate.
