U.S. President Donald Trump has escalated trade tensions with Canada by threatening steep tariffs on Canadian made aircraft, citing an ongoing dispute over aviation certification standards. The warning targets Canada’s refusal to certify several U.S. built Gulfstream business jets for operation in Canadian airspace.
Trump issued the threat in a social media post on Thursday, accusing Canadian authorities of wrongfully blocking certification approvals for key Gulfstream models. Trump described the certification process as a barrier preventing U.S. aircraft sales in Canada and signaled retaliation if no change follows.
Trump stated the U.S. administration would move to decertify Canadian made aircraft for use in the American market. The threat includes business jets produced by Montreal based Bombardier. Trump added a warning of a 50 percent tariff on any aircraft sold from Canada into the United States if Canadian regulators fail to approve the Gulfstream jets without delay.
Such measures would place significant pressure on the North American aerospace industry, with potential disruption across manufacturing, sales, and cross border operations. The aerospace sector relies heavily on reciprocal certification standards between Canada and the United States to support aircraft sales and fleet operations.
Bombardier responded late Thursday night, confirming awareness of Trump’s comments and ongoing communication with the federal government. The company emphasized compliance with U.S. Federal Aviation Administration standards across aircraft, facilities, and technical staff. Bombardier also highlighted ongoing investment focused on expanding operations within the United States.
Bombardier warned of broader consequences if the dispute continues, citing possible effects on air traffic operations and passengers. The company expressed hope for a swift resolution to limit disruption across the aviation system.
Industry rivalry adds further complexity. Bombardier and Gulfstream compete directly within the global business jet market, particularly within the large cabin, long range segment favored by corporate and government buyers. Trump’s remarks referenced several Gulfstream models, including the G500 and G600, along with flagship aircraft G700 and G800.
Bombardier produces the Global series of business jets, including the Global 6500, Global 7500, and Global 8000. These aircraft already hold certification for operation within both Canadian and U.S. markets.
Aircraft certification determines eligibility for sale, registration, and flight within national airspace. Delays or refusals place manufacturers at a competitive disadvantage, raising economic stakes as political pressure intensifies between two closely linked aviation markets.
