In this case, Les Canadiens, as in the case in February where a Chinese purchased a B.C. chain of seniors homes, did "we" (i.e.: the sovereign country of Canada) sell ANYTHING  for ANY price, let alone, "on the cheap"?

Ans: no.  

These are private enterprise sales, not sales of Crown corps or anything else that the Canadian public might "own."  If they are bought "on the cheap," then the owners and/or stockholders of these companies are fools. If it wasn't advantageous in the first case, they'd say "no deal." In the second, you'd hear from outraged stockholders.  

If, however, Bombardier decided to sell out to anybody from anywhere else, you might raise an objection as a Canadian--demand return payment of Quebec and Federal taxpayers dollars as part of the deal.  THAT might be fair.  Whaddya think?
