Few topics in Canadian agriculture generate as much debate as supply management in the dairy sector. The issue gained renewed attention when former U.S. President Donald Trump criticized Canada’s protectionist stance during NAFTA renegotiations, underscoring the need to reassess the system’s long-term viability.

While proponents argue that supply management ensures financial stability for farmers and shields them from global market volatility, critics contend that it inflates consumer prices, limits competition, and stifles innovation. A policy assessment titled Supply Management 2.0: A Policy Assessment and a Possible Roadmap for the Canadian Dairy Sector, conducted by researchers at Dalhousie University and the University of Guelph, sheds light on the system’s inefficiencies and presents a compelling case for reform.
Designed in the 1970s to regulate production and stabilize dairy prices, Canada’s supply management system operates through strict production quotas and high import tariffs. However, as successive trade agreements such as the USMCA, CETA, and CPTPP erode these protections, the system appears increasingly fragile. The federal government’s $3-billion compensation package to dairy farmers for hypothetical trade losses is a clear indication that the current structure is unsustainable.
Instead of fostering resilience, supply management has created an industry that is increasingly dependent on government payouts rather than market-driven efficiencies. If current trends persist, Canada could lose nearly half of its dairy farms by 2030 — regardless of who is in the White House.
Consumer sentiment is also shifting. Younger generations are questioning the sustainability and transparency of the dairy industry, particularly in light of scandals such as ButterGate, where palm oil supplements were used in cow feed to alter butterfat content, making butter harder at room temperature. Additionally, undisclosed milk dumping of anywhere between 600 million to 1 billion litres annually has further eroded public trust. These factors indicate that the industry is failing to align with evolving consumer expectations.
One of the most alarming findings in the policy assessment is the extent of overcapitalization in the dairy sector. Government compensation payments, coupled with rigid production quotas, have encouraged inefficiency rather than fostering innovation. Unlike their counterparts in Australia and the European Union — where deregulation has driven productivity gains — Canadian dairy farmers remain insulated from competitive pressures that could otherwise drive modernization.
The policy assessment also highlights a growing geographic imbalance in dairy production. Over 74% of Canada’s dairy farms are concentrated in Quebec and Ontario, despite only 61% of the national population residing in these provinces. This concentration exacerbates supply chain inefficiencies and increases price disparities. As a result, consumers in Atlantic Canada, the North, and Indigenous communities face disproportionately high dairy costs, raising serious food security concerns. Addressing these imbalances requires policies that promote regional diversification in dairy production.
A key element of modernization must involve a gradual reform of production quotas and tariffs. The existing quota system restricts farmers’ ability to respond dynamically to market signals. While quota allocation is managed provincially, harmonizing the system at the federal level would create a more cohesive market. Moving toward a flexible quota model, with expansion mechanisms based on demand, would increase competitiveness and efficiency.
Tariff policies also warrant reassessment. While tariffs provide necessary protection for domestic producers, they currently contribute to artificially inflated consumer prices. A phased reduction in tariffs, complemented by direct incentives for farmers investing in productivity-enhancing innovations and sustainability initiatives, could strike a balance between maintaining food sovereignty and fostering competitiveness.
Despite calls for reform, inertia persists due to entrenched interests within the sector. However, resistance is not a viable long-term strategy. Industrial milk prices in Canada are now the highest in the Western world, making the sector increasingly uncompetitive on a global scale. While supply management also governs poultry and eggs, these industries have adapted more effectively, remaining competitive through efficiency improvements and innovation. In contrast, the dairy sector continues to grapple with structural inefficiencies and a lack of modernization.
That said, abolishing supply management outright is neither desirable nor practical. A sudden removal of protections would expose Canadian dairy farmers to aggressive foreign competition, risking rural economic stability and jeopardizing domestic food security. Instead, a balanced approach is needed — one that preserves the core benefits of supply management while integrating market-driven reforms to ensure the industry remains competitive, innovative and sustainable.
Canada’s supply management system, once a pillar of stability, has become an impediment to progress. As global trade dynamics shift and consumer expectations evolve, policymakers have an opportunity to modernize the system in a way that balances fair pricing with market efficiency. The recommendations from Supply Management 2.0 suggest that regional diversification of dairy production, value-chain-based pricing models that align production with actual market demand, and a stronger emphasis on research and development could help modernize the industry. Performance-based government compensation, rather than blanket payouts that preserve inefficiencies, would also improve long-term sustainability.
The question is no longer whether reform is necessary, but whether the dairy industry and policymakers are prepared to embrace it. A smarter, more flexible supply management framework will be crucial in ensuring that Canadian dairy remains resilient, competitive, and sustainable for future generations.
