An Air Canada Bombardier CRJ-900LR aircraft is seen at Ronald Reagan Washington National Airport (DCA) in Arlington Virginia, on Oct. 5, 2025.

President Donald Trump on Monday said Bombardier , a Canadian airplane manufacturer, must build its products in the U.S. in order to keep selling in the American market.

The move comes amid a bitter trade war between the U.S. and Canada, and on the eve of retaliatory tariffs set to take effect Tuesday on a range of U.S. goods.

"NO MORE SELLING BOMBARDIER IN THE UNITED STATES!" Trump wrote on Truth Social.

"If they want our Market, they must build here, and stop treating America like a 'piggybank,'" he wrote.

Bombardier didn't immediately respond to a request for comment.
