Donald Trump has threatened to block Bombardier aircraft sales in the United States unless the Canadian business jet maker builds in the country, drawing pushback from the International Association of Machinists and Aerospace Workers. The move targets Bombardier’s Challenger and Global business jets, which remain approved by the Federal Aviation Administration, while the company’s U.S. market dependence makes any restriction commercially significant.
The dispute comes amid a widening trade fight between Washington and Ottawa, with Canada’s retaliatory tariffs taking effect around the same time. Bombardier has a substantial American footprint, including thousands of employees and a supply chain tied to U.S.-made components, complicating any attempt to enforce a ban.
Aviation lawyers and analysts have questioned how the administration could implement the threat without a formal regulatory mechanism. White House officials have not detailed any enforcement steps, and no actual U.S. ban is in place. The latest response from IAM framed any restriction as harmful to workers on both sides of the border, while Bombardier has defended its existing U.S. operations.
