Thank you.
With respect to domestic legislative change, we have met with the Dairy Farmers of Canada and we've met interdepartmentally on it. We're seized of the issue of the concern of the Dairy Farmers, but we are constrained by the legislation. We can't raise tariff rates without legislation; there's no regulatory or order in council authority that would allow the government to move forward with raising rates without legislation.
With respect to article 28 and the history of Canada's involvement in such negotiations, perhaps Mr. Beyea can respond.
