U.S. President Donald Trump overnight Thursday threatened "decertifying" Bombardier Global Express and "all aircrafts made in Canada" until U.S. aviation company Gulfstream is fully certified, Canada's CTV News reported.

"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 into the United States of America," Trump wrote on Truth Social.

Bombardier overnight issued a statement in response, "We have taken note of the post from the President of the United States to social media and are in contact with the Canadian government. Bombardier is an international company that employs more than 3,000 people in the U.S. across 9 major facilities, and creates thousands of U.S. jobs through 2,800 suppliers. Our aircraft, facilities and technicians are fully certified to FAA standards and renowned around the world. We are actively investing in expanding our U.S. operations, including a recent announcement in Fort Wayne, Indiana."

It added: "Thousands of private and civilian jets built in Canada fly in the U.S. every day. We hope this is quickly resolved to avoid a significant impact to air traffic and the flying public."

CTV News aviation expert Phyl Durdey pushed back on U.S. threats to target Canada's aviation sector, saying Trump has no authority to "arbitrarily" decertify Canadian aircraft. In an interview with CTV News Channel on Thursday, Durdey said the U.S. Federal Aviation Administration (FAA) certifies or decertifies all aircraft in the U.S. He also noted that the U.S. has "lots of operating aircraft that are supplied from Canada," with thousands of Canadian-built jets flying south of the border, too.

CTV noted the U.S. military itself relies on Bombardier aircraft, using a fleet of modified Global Express jets known as the BACN aircraft or Air Force E-11A, one of which is currently being deployed to the Middle East. Durdey warned that any move against Bombardier would hurt U.S. economic interests as much as Canada's.

Class A and B shares in Canadian plane maker Bombardier were both down yesterday, but are trading at the high end of their 52 week trading range.
