President Trump warned Bombardier, the Canadian business jet manufacturer, that it would be barred from selling in the United States unless it moves production there, escalating a trade dispute with Ottawa. Trump previously threatened to decertify Bombardier jets and impose steep tariffs, arguing Canada restricted sales of U.S. rival Gulfstream Aerospace. During his first term, the Commerce Department imposed a nearly 300 percent tariff on Bombardier passenger jets after Boeing accused it of unfair government subsidies. Bombardier, headquartered in Montreal, responded by noting it manufactures parts in California and Texas, employs thousands across 20 U.S. states, and relies on 2,800 American suppliers.

Founded in 1942 by Joseph-Armand Bombardier in rural Quebec, the company evolved from snowmobiles into rail and aviation, acquiring Canadair and Learjet. After ending its commercial jet program following the 2017 Boeing dispute and selling its rail division in 2021, Bombardier focuses on Challenger and Global business jets. The U.S. is its largest market, hosting roughly half of its 5,200-aircraft fleet. U.S. airlines like Endeavor Air and SkyWest operate its regional jets, while the U.S. Air Force and Army use modified Bombardier aircraft for surveillance. About 55 percent of its $9.6 billion in 2025 revenue came from the U.S.
