MONTREAL — Bombardier and the federal government have rejected Boeing's claim in a complaint filed with the U.S. government that its Canadian rival has dumped its new CSeries commercial jet into the United States at below cost. "Bombardier structures its commercial dealings to ensure compliance with the laws and regulations of the jurisdictions in which we operate, including those issues raised by Boeing,'' the Montreal-based aircraft manufacturer said in an emailed statement. The world's third-largest airplane maker said it spends about US$3 billion annually with U.S. suppliers and employs about 7,000 people in dozens of facilities in both rail and aerospace across 17 states.

The Seattle-based competitor said Thursday that it petitioned the U.S. Department of Commerce and the U.S. International Trade Commission for investigations into subsidies and pricing of the CSeries. It is also seeking an order to be issued against the sale of the plane in the important American market. Economic Development Minister Navdeep Bains said the government objects to the allegations and vowed to mount "a vigorous defence.'' "We are confident that our programs are consistent with Canada's international obligations,'' he said in a statement. Boeing said it asking the Trump administration to act "to end Bombardier's illegal and unfair business practices before it is too late to prevent significant harm to America's aerospace industry and thousands of good-paying aerospace jobs.'' The aerospace giant said the threat against its suppliers will only grow as Bombardier increases the annual production rate of the CSeries to between 90 and 120 airplanes by 2020.
