What do you mean by a sell out? Do you think Canada should defend a no tariff trade agreement with a low wage country like Mexico that has caused manufacturing plants in Canada and the USA to relocate with the effect of leaving  nothing but a hard scrabble service economy here at home? Products that were once built here are now imported  at the same or higher price and we're still expected to buy them. Ever wonder about Mexican wages?  Globe and Mail article from Feb. 2015 about a transmission plant -  $2.90/hr and that's at a the high end of it.   There is absolutely no way we can compete with that.
I would encourage our Government to work closely with the incoming Trump administration 
to break NAFTA and impose punitive tariffs on Mexico and other low wage countries to level off the playing field. Free (no tariff) trade with countries with similar standards of living is usually beneficial 
but with low wage/low standard countries it's ruinous to the high living standard country.
