Canada will remove many retaliatory import tariffs on U.S. goods and intensify talks with the United States on striking a new trade and security relationship, Prime Minister Mark Carney said on Friday.

The change will go into effect on Sept. 1, Carney added, saying he believes Canada has the best trade deal out of all of the countries working with the U.S.

Canada’s leader said he would follow the United States in dropping tariffs against American goods covered by the existing free trade agreement.
