The Mrs. said that the trucking provisions weren't in the treaty. They were binding regulations added later. That's what I mixed up...and that's why she gets paid to be the journalist, and I don't...
The link in my above reply says that the provisions were in NAFTA.
I think everyone might be correct here. The trucking provisions are not in the text of the treaty itself, but the treaty might have one or more codicils that specifically address the subject. So for someone like me, that means it's not in the treaty, but for someone like a journalist, it's not worth the time or effort to explain the difference.
