It was not a smart move to give up control of the CSeries over to Airbus with nothing in return.  Bombardier clearly went cap in hand to Airbus and they left the meeting without their shirt and pants.

In 5 years, Airbus will have the full rights to the CSeries.  What would be interesting is whether Bombardier will still own the IP and royalties gained from the CSeries.  As for keeping production in Canada? What makes you think Airbus will not move production to their US plant in 5 years?
