President Trump, who has insisted Aug. 1 is a firm deadline for countries around the world, said that "the complexities of a Deal with Mexico are somewhat different from other Nations."

OTTAWA (Reuters) -The Canadian team working on a trade deal with the United States could walk away from talks in the wake of a U.S. decision to impose a 35% tariff on some goods from Canada, an adviser to Prime Minister Mark Carney said on Friday.

President Trump will impose a 35% tariff on Canada, up from 25%, as the White House pushes countries to finalize trade deals. Mexico received a 90-day extension, while Trump said other nations have until the deadline to negotiate or face new tariffs.
