President Trump threatened to ban the sale of Bombardier aircraft in response to Canada's impending retaliatory tariffs. President Trump criticized that Canada was unfairly relying on the US market while restricting US companies from entering Canada, arguing that Bombardier should be free to operate in the United States. He argued that Canada was blocking US companies from entering its market while depending on the vast US market. In January, President Trump threatened to impose a 50% tariff on Canadian-made aircraft until Gulfstream aircraft received certification from the Canadian government, and Canada certified Gulfstream aircraft in February. However, Bombardier aircraft use engines from US companies and have employment, production, and supply chains within the United States, raising questions about whether the sales ban will be implemented.
