Key Takeaways:

Former President Donald Trump threatened to decertify all Canadian-made aircraft and impose a 50% tariff on them, citing Canada's alleged refusal to certify Gulfstream 500-800 business jets.
The legality of such a presidential action is uncertain, as aircraft certification is typically handled by the FAA based on airworthiness and safety, not economic or political reasons.
Canadian manufacturer Bombardier highlighted its significant U.S. workforce and operations, expressing concern that the situation could impact air traffic and the flying public if not resolved quickly.

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.
