Yes, we really got shafted by NAFTA ... that`s why it is now enthusiastically supported by the same Liberals who opposed it in 1993 to con folks like you  while knowing it was good for Canada and that is why even the NDP no longer undertakes the fools`errand of knocking NAFTA.  Why those dastardly villains Mulroney and Harper (don't forget Harper) with their trade and tax and fiscal policies so shafted  Canada that its middle class (the one that the phony middle class champion could not even define during the election)  overtook the US middle class in 2013/14 to become the wealthiest middle class in the world.   And on a proportional basis, the country in NAFTA which had the greatest net job gain since it came into force 23 years ago is Canada.  

Try reading up on the topic before posting your long held biases.

Yes, Mulroney would be the perfect Canadian adviser and negotiator in regard to a review of and revisions to NAFTA if at 77 or 78 he is willing to get involved.
