[Trump Threatens to Impose 50% Tariff on Canadian Aircraft] According to CCTV News, on the 29th local time, U.S. President Trump posted on his social media platform 'Truth Social,' stating that Canada has 'wrongfully, illegally, and for a long time' refused to certify the U.S. Gulfstream 500, 600, 700, and 800 business jets, constituting unfair treatment of American companies. In response, the U.S. will suspend certification of the Bombardier Global Express series and all Canadian-manufactured aircraft until Gulfstream jets receive full certification. He warned that if the issue is not immediately resolved, a 50% tariff will be imposed on all Canadian aircraft exported to the United States.
