Bombardier shares fell sharply after President Donald Trump threatened the Canadian private jet maker’s access to the lucrative U.S. market, which accounts for roughly half of the company’s total sales.
Shares slipped 3% in morning trading after opening down as much as 6.4%, reflecting investor concern over the escalating trade dispute between Washington and Ottawa.
Trump took to Truth Social to demand that the Montreal-based planemaker establish domestic assembly operations in the United States or face an outright ban on aircraft sales.
“NO MORE SELLING BOMBARDIER IN THE UNITED STATES!” Trump wrote, framing the threat as part of his broader campaign to push foreign manufacturers toward domestic production.
Trump argued that more than 50 percent of Bombardier’s revenue comes from U.S. customers, while Canada blocks companies such as Gulfstream Aerospace from doing business there.
He warned that “if they want our Market, they must build here, and stop treating America like a ‘piggybank,'” sharpening his rhetoric as Canada introduced counter-tariffs on $20 billion worth of U.S. goods.
It remains unclear exactly how Trump would bar Bombardier jets from reaching American customers, given that the aircraft have already been approved by the U.S. Federal Aviation Administration.
Professor Mehran Ebrahimi of the University of Quebec at Montreal noted that the president cannot legally target a single company, but could target a specific type of jet with certain characteristics that would effectively impact Bombardier.
Trump said in July that his administration might impose levies on imports of commercial aircraft, engines, and related parts after the U.S. Department of Commerce wrapped up a Section 232 investigation concluding those imports present a national security threat.
Bombardier employs approximately 3,500 American workers and works with 2,800 U.S.-based suppliers, with parts produced in traditionally Republican states including Texas.
The company also operates a U.S.-based defense unit in Wichita, Kansas, where a factory militarizes Canadian-built business jets for American defense contracts.
Congressman Ron Estes, who represents Kansas’s fourth district, said on Monday night that he opposes tariffs on aerospace and defended Bombardier’s contribution to his state.
Trump has faced growing internal pushback from Republican lawmakers as his escalating trade war with Canada emerges as a political liability in several states ahead of the November midterm elections.
Bombardier pushed back against the pressure to shift manufacturing to the United States, releasing a statement that read: “The American aerospace industry is a clear winner on trade and exports. Bombardier is a strong contributor to the sector, creating tens of thousands of jobs across the United States.”
Analysts estimate Bombardier’s full-year 2026 revenue at approximately $10.2 billion, meaning a U.S. market ban could put close to $5 billion in annual sales at direct risk.
