David Wiens, president of Dairy Farmers of Canada, said the country must avoid granting additional concessions to foreign dairy imports. He argued that supply management plays a crucial role in ensuring stable prices, predictable farmer income and reliable domestic production during a period of global economic uncertainty. Established in 1972, the system covers dairy, poultry and eggs, aligning production with domestic demand to maintain market stability.

The Canadian government has reaffirmed its support for the framework. Agriculture Minister Heath MacDonald said supply management will not be part of CUSMA negotiations, while legislation passed in 2025 prohibits Canadian trade negotiators from offering concessions such as expanded import quotas or lower tariffs for supply-managed products. The government says its priority is strengthening trade relationships while protecting Canadian farmers and food security.

However, policy analysts say the system remains a persistent trade irritant with the United States. Some experts argue that meaningful trade negotiations typically require all issues to be open for discussion. Others suggest the system could be modernized independently of trade talks, potentially through reforms that adjust production quotas or reduce price support mechanisms.
