The president revived his discredited claims about fentanyl entering the U.S. from Canada to justify his latest proposed rate of 35 percent.
President Trump threatened on Thursday to impose a 35 percent tariff on Canadian imports, upending negotiations between the countries that had Canada’s representatives hopeful that a trade deal could be reached in a matter of weeks.
Mr. Trump posted a letter to Prime Minister Mark Carney of Canada on social media outlining his latest threat. He said the new, higher tariff rate for Canada would go into effect on Aug. 1, though it was unclear if it would affect all Canadian goods, or if he would follow through. Mr. Carney’s office did not immediately respond to requests for comment about Mr. Trump’s letter.
