Experts doubt Trump’s threat to bar new Canadian-built planes from U.S. skies
A presidential threat to decertify Canadian-made aircraft faces legal and logistical hurdles, experts say. Any move would likely hit supply chains and jobs on both sides of the border.

U.S. President Donald Trump said he would decertify Canadian-made aircraft and impose tariffs, but aviation experts and industry figures say the administration has limited authority to carry out such a move. The dispute highlights how aircraft certification, trade and safety oversight intersect across the Canada-U.S. aerospace sector.
Officials later clarified the action would apply only to new aircraft still coming off assembly lines, not the more than 5,400 Canadian-built planes and helicopters already registered in the United States. Still, the announcement has raised concerns about supply chains, jobs and regulatory precedent.
What the president announced
On social media, Mr. Trump named Bombardier and said he would decertify Bombardier Global Express jets and all aircraft made in Canada until certain Gulfstream models were certified in the U.S. The White House later said the measure would target only new aircraft. The initial message and the backtracking together have left industry stakeholders seeking clarity.
The FAA is controlling the certification. Mr. Trump has no authority to do that.

How certification actually works
Aircraft certification in the United States is managed by the Federal Aviation Administration. Certification is a technical, years-long process that examines whether a design meets safety standards under predictable operating conditions. Historically, groundings and decertifications have been based on safety findings rather than political decisions.
This is really strange, because certification of aircraft is a very, very long process. It takes years.

Gulfstream’s G700 and G800 jets, for example, have not been certified in Canada. The FAA granted a conditional, temporary exemption that requires Gulfstream to show the models function properly where ice may form in the fuel system. That conditional status is central to the debate about whether any administrative action could be limited, and how it would be implemented.
Which aircraft and companies would be affected
A range of aircraft types are assembled in Canada, from business jets to regional airliners and helicopters. Industry players say a move to restrict new Canadian-built aircraft would ripple through cross-border production networks.
- Bombardier business jets and regional planes
- Airbus A220 single-aisle jets, assembled in Mirabel
- Bell Textron helicopters with Canadian assembly work
- De Havilland Dash 8-400 turboprops and other models
Economic and industry impact
Industry analysts warn that tariffs or a ban on new aircraft could damage integrated North American supply chains and jobs. Bombardier reports about 3,000 employees at nine U.S. sites and around 2,800 U.S. suppliers, and its jets often contain at least 40 per cent U.S. content. The U.S. also runs a trade surplus with Canada in aerospace, complicating policy justifications based on trade imbalances.
Subsequent clarifications by administration officials suggest that Canadian-made aircraft in operation already would not be grounded due to a move to decertify.

Labour groups emphasise the interdependence of the two countries’ aerospace sectors. The International Association of Machinists and Aerospace Workers warned that politically motivated action would threaten jobs and disrupt production.
Aircraft certification must remain independent and grounded in safety, not politics. Politically motivated decertification would create instability, threaten thousands of jobs on both sides of the border, and undermine the integrity of the aviation system we all depend on.

Legal and safety concerns
Regulators have grounded aircraft in the past for safety reasons, most notably the Boeing 737 Max 8, which was banned for 20 months after fatal accidents. Experts say using safety regulators as a tool for immediate political objectives could set a risky precedent and face legal challenges.
Lawyers and aviation specialists expect disputes over any attempted decertification or tariffs to play out in courts and regulatory processes. That would likely prolong uncertainty for airlines, manufacturers and travellers.
What happens next
For now, industry leaders and regulators are watching for formal actions and legal notices. Canadian officials and companies have called for calm while assessing exposure and contingency plans. Analysts say the combination of regulatory procedure and cross-border industrial ties makes an abrupt, sweeping ban unlikely without lengthy legal and technical battles.
Experts advise stakeholders to prepare for a period of uncertainty that could affect orders, deliveries and supply chains, even if any actual restrictions are limited to future production.
