Bombardier stock slides after Trump demands U.S. assembly or sales ban

Investing.com — Bombardier Inc (TSX:BBDb) shares fell 6.4% after U.S. President Donald Trump demanded the Canadian business-jet maker set up domestic assembly operations or face an outright ban on selling aircraft in the United States. In a Truth Social post, Trump wrote "NO MORE SELLING BOMBARDIER IN THE UNITED STATES!" and sharply criticized the Montreal-based planemaker, asserting that "their products aren't good enough!" as part of widening cross-border trade friction.

The retaliatory rhetoric underscores Bombardier's heightened operational exposure, as the U.S. accounts for more than half of its total revenue. Trump highlighted that dynamic, noting the planemaker's commercial model "lives off American Buyers, American Companies, American Airports, and American Service," while accusing Ottawa of blocking "our GREAT American Banks, and Companies" and previously stalling Gulfstream Aerospace's operations in Canada.

Against that backdrop, market observers remain skeptical about the administrative mechanics needed to enforce such a ban. Bombardier's fleet already maintains full compliance under the Federal Aviation Administration and operates within the tariff frameworks established by the United States-Mexico-Canada Agreement.

Trump framed the proposed restrictions as an imperative to compel domestic manufacturing, stating "that Era is OVER!" and warning that "if they want our Market, they must build here, and stop treating America like a 'piggybank.'" The friction continues a recurring regulatory leverage strategy between Washington and Ottawa, following similar White House threats in January to decertify Bombardier's Global Express lineup.

The timing of the social media barrage coincides directly with Ottawa's implementation of a broad wave of counter-tariffs targeting American imports. This rapid tit-for-tat escalation signals a breakdown in diplomatic negotiations, heightening regional trade barriers and stoking volatility across supply chains on both sides of the border.

Industry analysts ultimately caution that shutting Bombardier out of the American market could carry broader economic blowback within the domestic aerospace sector. With the planemaker maintaining extensive service networks, component suppliers, and specialized military modification facilities across multiple U.S. states, aggressive regulatory intervention risks disrupting established commercial partnerships throughout North America.
