Jan. 30 (UPI) -- President Donald Trump on Thursday night said he was decertifying all Canada-made aircraft and threatened a 50% tariff on all planes sold to the United States, further deepening the fissure in U.S.-Canada relations created under Trump's second term in office.
Trump made the threat in a post on his Truth Social platform, stating the threat was in response to Canada's alleged refusal to certify several Gulfstream jet series.
"We are hereby decertifying their Bombardier Global Expresses and all Aircraft made in Canada, until such time as Gulfstream, a Great American Company, is fully certified, as it should have been many years ago," Trump said.
"Further, Canada is effectively prohibiting the sale of Gulfstream products in Canada through this very same certification process. If, for any reason, this situation is not immediately corrected, I am going to charge Canada a 50% Tariff on any and all Aircraft sold in the United States of America."
By law, aircraft certification, which includes safety and airworthiness determinations, is governed by the Federal Aviation Administration, and it was not clear if the president has the power to decertify already approved aircraft by presidential action.
