What does
any of that have to do with where Canada is located?
Anthropological North America is the region from the Rio Grande to the Arctic Ocean. The behavior of the people who lived there is utterly and bafflingly irrelevant to a discussion of where it's located.
Mesoamerica is its own anthropological region and is not considered with North America in anthropology, which, again, begins at the Rio Grande. The Maya are Mesoamerican, not North American.
Congratulations, I did, too, since I predicted from day one that this was going to be a fan service pack. The people speculating on all manner of obscure and unexpected civs, however worthy, were bound to be disappointed. I expected Assyria over Babylon and Gaul was a surprise, but overall NFP has been exactly what I predicted it would be. And to that end a second Oceania civ has a 0% chance of making it into NFP. Very few people are asking for it; it doesn't suit the purpose of the pass.
Well, then I think you're in for a pleasant surprise. I think you're regarding their "rules" as much more sacrosanct than they do. NFP exists as fan service, pure and simple. We've had a few surprises, but they're not going to pick Hawai'i when Portugal or a Native North American civ will sell better and will round out the roster better before they move on to whatever is in development next.
