IAM Condemns Trump’s Threat to Decertify Canadian Aircraft Amidst Escalating Trade War

January 30, 2026, The International Association of Machinists and Aerospace Workers (IAM) has issued a stern warning following U.S. President Donald Trump’s threat to decertify Canadian-made Commercial-Aircraft and impose a 50% tariff on their import. The union, representing aerospace workers across North America, argues that weaponizing aviation safety certification for political leverage threatens the stability of the entire industry.

The dispute escalated on January 29, when President Trump took to Truth Social to announce punitive measures against Canada. Citing an alleged refusal by Transport Canada to certify U.S.-made Gulfstream business jets, the President threatened to “decertify” Bombardier Global Express aircraft and “all Aircraft made in Canada” unless the situation is “immediately corrected.”

In a press release issued shortly after the President’s remarks, the IAM emphasized that the North American aerospace supply chain is deeply integrated, and such measures would harm workers on both sides of the border.

Union Leaders Call for Safety Independence

The IAM’s primary objection centers on the politicization of safety protocols. Under international agreements, aviation certification is a technical process designed to ensure airworthiness, not a lever for trade negotiations. The union warns that deviating from this standard sets a dangerous precedent.

In the official statement, IAM Canadian General Vice President David Chartrand condemned the strategy:

“Any attack on Canadian aircraft harms both Canadian and American workers alike. Aircraft certification must remain independent and grounded in safety, not politics.”

The union highlighted that the aerospace ecosystem relies on the seamless movement of parts and finished goods between the United States and Canada. A 50% tariff would effectively halt Canadian exports to the U.S., impacting not only Canadian assembly lines but also the thousands of U.S. suppliers that provide engines, Avionics, and landing gear for these aircraft.

IAM International President Brian Bryant urged the administration to pivot its focus toward domestic labor issues rather than trade wars:

“The Trump administration should focus on closing the loopholes that continue to fuel the offshoring of aerospace… jobs across North America.”

, Brian Bryant, IAM International President

Context: The Carney-Trump Standoff

This aviation dispute occurs against a backdrop of deteriorating diplomatic relations between Washington and Ottawa. Tensions have risen sharply since Canadian Prime Minister Mark Carney took office. According to political analysts, the friction was exacerbated by PM Carney’s January 20 speech at the World Economic Forum, titled “Principled and Pragmatic: Canada’s Path,” which criticized economic coercion.

The specific grievance cited by the White House involves Gulfstream Aerospace. The Trump administration alleges that Canada has “wrongfully” delayed the certification of Gulfstream’s G500, G600, G700, and G800 jets to protect Bombardier, a domestic competitor. While the G700 and G800 only received FAA certification in 2024 and 2025 respectively, the administration claims the delays are protectionist in nature.

Market Impact and “Decertification” Risks

The threat to “decertify” aircraft is legally complex but economically potent. Following the President’s statement, Bombardier’s stock fell approximately 5.4%. However, the threat extends beyond business jets. By targeting “all Aircraft made in Canada,” the administration puts the Airbus A220 program at risk.

The A220, assembled in Mirabel, Quebec (with a second line in Mobile, Alabama), is a workhorse for U.S. carriers including Delta Air Lines and JetBlue. Tariffs on Canadian-assembled units could significantly increase fleet renewal costs for these U.S. Airlines.

AirPro News Analysis: The Breakdown of Mutual Recognition

The most significant aspect of this development is not the tariff itself, but the threat to the Bilateral Aviation Safety Agreement (BASA). For decades, the FAA and Transport Canada have operated under a system of mutual recognition, where one regulator accepts the testing and data of the other to streamline certification.

If the U.S. Executive Branch overrides the FAA to unilaterally “decertify” foreign aircraft for non-technical reasons, it undermines the global framework of aviation safety. We assess that this could lead to retaliatory measures from other regulators, such as EASA (Europe) or CAAC (China), potentially subjecting Boeing aircraft to similar political delays abroad. As the IAM noted, the “tremendous consequences” would likely be felt by the flying public and the workforce long before they are felt by political leadership.
