U.S. President Donald Trump has escalated trade tensions with Canada by threatening to decertify Canadian-manufactured aircraft and impose a 50 percent tariff on aircraft sales into the United States.
In a statement published on Truth Social, Trump said the move would target Bombardier’s Global Express business jets and could potentially extend to all aircraft built in Canada. The announcement was framed as retaliation for what Trump described as Canada’s refusal to certify several Gulfstream Aerospace models, including the G500, G600, G700, and G800.

Trump praised Gulfstream as a leading U.S. aerospace manufacturer and said the proposed measures would remain in place until the affected aircraft receive certification approval in Canada. He also warned that new tariffs would be applied if the issue is not resolved quickly.
The move would directly impact Quebec-based Bombardier, one of Gulfstream’s main competitors in the global business aviation market. Aviation experts, however, have raised questions about the legal feasibility of unilateral aircraft decertification, noting that certification processes are governed by bilateral regulatory agreements and international safety standards.
Bombardier confirmed it is in contact with Canadian authorities and stated that its aircraft comply with U.S. Federal Aviation Administration certification requirements. The White House later clarified that aircraft already in service would not be affected by the proposed measures.
Industry analysts warn that if implemented, the decision could disrupt North American aerospace supply chains and increase costs for operators.
