U.S. President Trump Signals Tough Action Against Canada Over Aircraft Certification Dispute

January 30, 2026

U.S. President Donald J. Trump has issued a sharp warning to Canada over what he describes as an unfair and prolonged refusal to certify American-made Gulfstream business jets. The dispute, centered on aviation regulatory approvals, has now escalated into a potential trade confrontation between the two neighboring countries.

In a public statement, President Trump accused Canadian authorities of using regulatory procedures to block Gulfstream aircraft from entering the Canadian market. He argued that the move has effectively restricted sales of advanced U.S. jets while Canadian aircraft manufacturers continue to benefit from access to the American aviation market.

U.S. Considers Decertifying Canadian Aircraft

Responding to the situation, President Trump announced that the United States is prepared to withdraw certification recognition for Canadian-built aircraft, including business jets manufactured by Bombardier. According to the President, this step would remain in effect until Canada fully approves Gulfstream aircraft through what he described as a fair and transparent certification process.

Trump emphasized that aviation certification should not be used as an economic weapon and claimed that the issue has been unresolved for far too long.

Threat of Steep Tariffs

In a further escalation, President Trump warned that if Canada does not immediately correct the situation, his administration may impose a 50 percent tariff on all aircraft manufactured in Canada and sold in the United States. Such a move could have significant consequences for the North American aerospace industry, which relies heavily on cross-border cooperation.

Trade experts caution that higher tariffs could increase aircraft costs, disrupt supply chains, and lead to retaliatory measures from Canada.

Impact on Aviation and Trade Relations

The U.S. and Canadian aviation sectors are deeply interconnected, with shared manufacturing networks, regulatory coordination, and joint safety standards. Any breakdown in certification cooperation could affect airlines, private jet operators, and defense-related contracts across both countries.

So far, Canadian officials have not issued a formal response to the latest statements. Aviation regulators in Canada traditionally maintain that certification decisions are made solely on technical and safety grounds, independent of political pressure.

Strong Trade Posture from the White House

President Trump’s remarks reflect his administration’s broader push to protect American manufacturing and challenge trade practices he views as discriminatory. The development adds fresh strain to U.S.-Canada relations, despite the long-standing partnership between the two nations.

Whether the dispute leads to formal trade action or renewed negotiations remains to be seen. However, the President’s warning has already sent ripples through global aerospace markets and raised concerns about the future of bilateral trade cooperation.
