Bellemare said in an interview that he is disappointed but not surprised by the U.S. Department of Commerce's decision Wednesday to impose duties of 292.21 per cent.
"The United States is committed to a free, fair and reciprocal trade and will always stand up for American workers and companies being harmed by unfair imports", he adds.
Labelling Boeing's complaint "meritless" and a "cover to close the US market", Mr Turner called on the US International Trade Commission (ITC) to set aside the Commerce Department's decision when it hears the next stage of the complaint in February.
"Today's decision validates Boeing's complaints regarding Bombardier's pricing in the United States, pricing that has harmed our workforce and US industry", it added.
Canadian Foreign Affairs Minister Chrystia Freeland echoed Bombardier's lament, saying Ottawa is "deeply troubled by the protectionist nature of Boeing?s allegations".
"Boeing is using its meritless complaint as cover to close the U.S. market, which is one of the biggest in the world, to new entrants such as Bombardier's C Series aircraft", he said.
"It is beyond all reason that Boeing could be threatened with injury in a market segment it exited over a decade ago", she said.
Boeing says the CSeries benefited from hundreds of millions of dollars in launch aid from the governments of Canada and Britain and a $1 billion equity infusion from the province of Quebec. The U.S. decision means that the relations between the country and its neighbor, Canada are likely to be terribly strained. Bombardier and Boeing argued their cases Monday before the ITC, an independent, quasi-judicial US agency.
But the Commerce Department's statement on Wednesday said that Bombardier, petitioners and the government of Canada agreed that that proposed agreement "does not impact these investigations".
Under a newly forged Bombardier-Airbus partnership a new manufacturing plant will be built in Alabama where the planes will be assembled, providing a possible avenue to avoid the hefty duty. The trade dispute stems from a complaint by USA aerospace giant Boeing against its Canadian rival that found a receptive ear in President Donald Trump, whose "America First" agenda has included taking a tough line in matters of worldwide commerce.
