A trade dispute is escalating between the US and Canada. Components for planes, such as wings, are made in the US by Bombardier, a Canadian jetmaker. The company's supply chain also relies on US businesses.

US President Donald Trump has made threats against the company, saying it must manufacture planes in the US to sell them there. Canada has retaliated against US tariffs with its own tariffs on US goods.

Further details on the trade tensions and Trump's statements are available from the source, including a social media post where he expressed his dissatisfaction with Bombardier.
