I'm guessing it would be America, which is less of a problem because statistically most Redditors are American, and the two countries are diplomatically and socially very close, so a large number of Americans visiting a sub about small Canadian towns is less surprising than large amounts of Russians.
I guess the question comes down to posting. Is it better for an American to weigh in on issues facing Red Deer, or a Russian? If they're honest, I think either is fine. If they're cosplaying as an Albertan, both are problematic.
