U.S. President Donald Trump is threatening to slap a 35 per cent tariff on all Canadian goods as the two countries have been engaged in negotiations to reach some sort of trade agreement.
Trump's latest threat came in a letter to Prime Minister Mark Carney that the president posted to his social media site, Truth Social, on Thursday evening.
"There will be no tariff if Canada, or companies within your country, decide to manufacture product within the United States," the letter reads.
Trump and Carney have been locked in negotiations to come to some sort of trade resolution by July 21.
