My reply #93 refutes that statement. There’s plenty more but you can use Google as easily as I can.

Reagan signed off on Canada/US trade. Not NAFTA.
Besides, why would you support Free Trade with Canada and not with Mexico? Either be a consistent protectionist or not...
But of course, the chuckaboot Johnny-come-lately types like to reimagine Reagan as a Nationalist, something he was far from being. If they want to look at someone who enjoyed bailing out "Amurcan industry", they should look at his predecessor, Jimmuh Carter, who bailed out Lee Iacocca with the guarantee of the US taxpayer.
If by "signed off" you mean Reagan was against it you are dead wrong. Every living former president was for it. It's not going to change your opinion but there are plenty of articles at Google that say exactly that. plus the fact that I remember it.
The only person of any prominence who was against it was Ross Perot and that effectively handed Bush Sr. his ass on a platter.
Clinton actually bucked the labor unions in this matter.
