Canada's dairy farmers are warning Prime Minsiter Justin Trudeau in an open letter that the current U.S. text of the United States Mexico and Canada Agreement (USMCA) still contains a provision that would grant the US oversight into the administration of the Canadian dairy system.

The farmers say this will undermine Canada's sovereignty and the ability to manage the Canadian dairy industry without U.S. intervention.

The letter, which was signed by Dairy Farmers of Canada's president and chairs of all 10 provincial dairy associations, states that government officials had reassured dairy farmers following the signing of the USMCA and release of the U.S. text that the issue of U.S. oversight had not been agreed to by Canada, and would not be part of the final agreement. Farmers remain concerned that they have not yet seen a final text with the oversight clause excluded.

In the letter, farmers ask that the Prime Minister not sign the USMCA until the clause granting U.S. oversight of the Canadian dairy system has been removed from the agreement.
