Escalation in U.S.–Canada Trade Tensions

U.S. President Donald Trump said Thursday that he intends to revoke the certification of aircraft manufactured in Canada, while threatening to impose a 50% tariff on any Canadian-built aircraft sold in the United States. The announcement comes amid rising trade tensions between the two neighboring countries, part of a broader dispute that has intensified since Trump returned to office.

Trump argued that Canada is effectively blocking the approval of U.S.-made Gulfstream aircraft through its certification process, calling the situation unfair to American manufacturers.

A Regulatory Precedent with Legal Uncertainty

Trump explicitly mentioned the revocation of certification for Bombardier’s Global Express business jet and extended the threat to include “all aircraft manufactured in Canada.” However, no executive order has been issued, and no regulatory mechanism for such an action has been specified.

Aviation experts note that aircraft certification traditionally falls under the authority of the Federal Aviation Administration (FAA), not the presidency. To date, no U.S. president has directly revoked an aircraft’s certification, and industry specialists warn that politicizing aviation safety could set a dangerous precedent.

Risks to the U.S. Regional Aviation System

The potential consequences could be particularly severe for U.S. regional airlines. Bombardier manufactures the CRJ series of regional jets, which are widely used for feeder flights connecting smaller airports to major hubs. Currently, 648 Canadian-built CRJ aircraft are in service with U.S. airlines, operating more than 2,600 flights per day and providing approximately 175,000 passenger seats daily.

Grounding these aircraft could cause widespread scheduling disruptions, reduce connectivity for rural regions, and potentially eliminate air service at 64% of U.S. airports that rely exclusively on regional carriers.

Industry and Canadian Government Response

Bombardier emphasized that it employs roughly 3,000 U.S. workers across nine facilities and works with 2,800 American suppliers. Canadian officials said they are engaging with U.S. counterparts through diplomatic channels in an effort to prevent further escalation.

Canadian ministers stressed that the country’s aviation industry is safe and reliable, expressing confidence that the issue can be resolved, while acknowledging that the lack of clarity surrounding Trump’s comments has injected significant uncertainty into the sector.
