Canada and the United States are stepping up trade talks ahead of a new round of U.S. tariffs scheduled to take effect August 19. Canadian dairy farmers are also urging Prime Minister Mark Carney not to make additional concessions on the country’s supply management system. The United States has repeatedly criticized Canadian dairy market access. Dairy Farmers of Canada says Canada has already made several concessions during previous negotiations, only to face additional demands. Canadian officials say they remain committed to protecting supply management as trade talks continue ahead of the tariff deadline.
