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 said Canada’s announcement it will recognize a Palestinian state “will make it very hard” for the U.S. to reach a trade agreement.

Trump’s tariff hike still hits goods that are not covered by the USMCA. The Bank of Canada forecast this week that up to 95 percent of Canadian exports could qualify for exemptions under that agreement. Meanwhile, the share of Canadian companies claiming tariff exemptions has soared.
