Good thing they specified Canada. For a moment I thought it was Banff, Scotland. Said no one, ever.

Scarcely. This may be true in the most childlike pedestrian sense, but it holds zero water in terms of even the most basic understanding of New World archaeology and anthropology. There simply is no schemata in which we view the mesoamerican civilizations as having anything whatsoever to do with your South American cultures.

They are totally and completely unrelated and while I think they probably did have a notion of one another, it would have been very dim and mitigated through a long and unreliable trading chain of goods that rarely reached one or the other, and for which we have nearly zero archaeological evidence.

Central American or Mezo-American. The South American cultures are/were very different and unrelated culturally.

The Yucatan is a completely different region though, just FYI. They're talking here about the Peten which has a pretty different topology and climate.

Interestingly, if you said it was Vancouver Washington, no one would question you at all.

No one from the PNW, that's for sure. Redwood forests have a very different look to say nothing of the fact that the trees themselves are much bigger. Consider that the last of the great redwood groves are at least 600 miles to the south of BC.
