Talk of "renegotiating" NAFTA has probably taken a more serious tone/turn in the recent weeks.
You might want to be brought up some of the issues and I am just the man to do so since I am HKSAR's private attorney general and special prosecutor.
For reasons that no one can understand Canada was allowed extensions on "non-compliant" canadian laws (not compliant with NAFTA). They kept getting extensions until a "ultimatum" was arrived at.
The non-compliant laws, such as the Air Canada Public Participation Act circa 1986 were given "grandfather protection".
Meaning, as long as those non-compliant laws were not changed (and thus tolling the protections) it will be business as usual. But, if certain things were to occur, which I will not disclose at this time.
They would lose grandfather protections and open themselves up to sanctions by NAFTA and perhaps WTO and other trade laws. Problem was, someone that was able to push the issue and force them to change the foreign ownership rules, essentially destroying "Canadian nationalism" which in essence is not NAFTA compliant.
I'll leave that for now for you to ponder, you can extrapolate the rest.
