President Donald Trump on Thursday threatened to decertify all aircraft made in Canada because the country has not yet certified certain Gulfstream business jets.

“Based on the fact that Canada has wrongfully, illegally, and steadfastly refused to certify the Gulfstream 500, 600, 700, and 800 Jets, one of the greatest, most technologically advanced airplanes ever made, 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 wrote on Truth Social, his social media site.
