Once legal in Canada

[USBR]

Hello everyone!
Correct me if I am wrong. Once someone has obtained legal status in Canada with a Canadian green card, is it right to say that the person will be able to come back visit the US regardless previous status in country (illegal)?  I am saying that based on the North American Free Trade Agreement (NAFTA), which allows Canadian citizens or legal residents of Canada to come to the US without requirement of a visa.

No, if you are a PR, then you citizenship determines if you require a visitor visa to the US.  The PR status doesn't help you.  Also if you have a ban from the US, it doesn't matter if you become a Canadian citizen, you are still banned.
