People seem to forget that Boeing employs a lot of people at their Winnipeg plant, and so if Canada plays hard ball, then Boeing can shutdown their plant in Winnpeg, leaving many without jobs and less tax revenue. 

The reality is, we do subsidize Bombardier with Billions and they still can't build products that work or that anybody wants..I say...stop the bleeding and let Bombardier run their business on their own merit with NO hand-outs...It is not fair that the Canadian government is picking and choosing industries they want to subsidize and most of them are in Ontario and Quebec.
