OTTAWA — Canada’s top trade negotiators are heading back to Washington this week for more meetings with the Trump administration as the Opposition Conservatives urge Prime Minister Mark Carney to stop making concessions in pursuit of a tariff-free deal. Canada’s trade team has met with U.S. Trade Representative Jamieson Greer twice in the past two weeks. “In doing so, we are taking a Team Canada approach – working with provinces and territories, across party lines, to get the best deal for Canada,” Brunet said. The United States instead opted to let the agreement move to rolling annual reviews. The United States has cited provincial bans of U.S. booze and the supply management system that protects Canadian dairy as key trade irritants.
