A great move by Airbus but the end of the aerospace sector in Canada.
 And subsidies by the Canadian taxpayer will continue.

Bombardier, not Airbus, is still on the hook for as much as $700-million in funding for the C Series over the next three years. 
Airbus doesn't even have to assume any of Bombardier's debt, which has climbed in recent years to almost $9-billion (Canadian), nearly double its market value.  Money for nothing, C Series for free.
Trump is the big winner.
With the" right to work" legislation in Alabama, labor costs are much cheaper than in Canada, so expect to see Airbus move more of its Bombardier workforce to Alabama.
And, Boeing wont stand by idly.
They will want tariffs on all C300 series parts imported into the US.
What is even more egregious , is that we have a Govt here which is still promoting free trade.
Free trade has hollowed out our manufacturing sector , as well as our middle class wealth.
Reverse pyramid democracy will do that to ya..
