U.S. President Donald Trump escalated trade tensions with Canada on Thursday, threatening to decertify Canadian-made aircraft and impose steep tariffs unless Ottawa reverses its stance on certifying several U.S.-built Gulfstream business jet models. In a post on Truth Social, Trump accused Canada of “wrongfully” and “illegally” blocking certification for Gulfstream’s 500, 600, 700, and 800 series jets, which he described as among the world’s most advanced aircraft. Retaliatory Measures Threatened Trump stated the U.S. response would include decertifying Bombardier Global Express jets and potentially all aircraft manufactured in Canada. He argued that Canada is effectively prohibiting Gulfstream sales through its certification process. “If this is not immediately corrected,” Trump warned, his administration would impose a 50% tariff on all aircraft sold from Canada into the United States. Ongoing Trade Friction The remarks mark a significant escalation in bilateral trade relations, which have been strained in recent years. Canadian officials did not immediately issue a public response, and it remains unclear whether U.S. regulators have initiated formal steps to decertify Canadian aircraft. The dispute centers on reciprocal certification standards, with Gulfstream seeking access to the Canadian market comparable to what Bombardier enjoys in the United States.
