WE COULD NOT STAND BY GIVEN THIS ... ILLEGAL DUMPING.

to come, and we could not stand by given this clear case of illegal dumping,” the company said.

The spat prompted a strong response from the Canadian government, which planned on purchasing 18 Super Hornet fighter jets from Boeing but broke off discussions over the multibillion-dollar plan. The U.S. government approved the potential sale Tuesday, valued at US$5.23 billion.

A spokesperson from Global Affairs Canada on Tuesday called the petition “unjustifiable and based solely on Boeing’s desire to limit competition.”

Several airlines have also sided with Bombardier. Delta Air Lines, whose order for 75 CSeries jets is a crucial part of Boeing’s complaint, said in a briefing filed in May that there was “no reasonable indication or threat of material injury” to Boeing. Last month, low-cost carriers Spirit Airlines and Sun Country Airlines urged the U.S. government to reject Boeing’s complaint.

The CSeries aircraft is expected to be a key part of Bombardier’s success. In a report released Tuesday, the company forecast it would deliver 12,550 60-to-150 seat aircraft between 2017 and 2036, for a total value of $820 billion. The 100to-150 seat segment would represent about 70 per cent of revenues, with 6,800 aircraft valued at $580 billion. The company expects North America and Europe to remain the most significant markets for new aircraft.

The U.S. Commerce department is expected to announce its decision on whether to impose duties against Bombardier Sept. 25.
