^ What you are saying applies if one is simply saying this skyline is smaller or that skyline is bigger. Period.

But when one starts to make comparisons between two cities based on some parameter... like here, specifically comparing city skylines based solely on population numbers, the comparison loses all validity when that parameter for comparison (population in this case) doesn't mean the same thing. A metro area of one million in population in the US does not represent the same thing as a metro area of one million in Canada.

You can simply say that Calgary has a more impressive skyline than Jacksonville and that is completely true (whether Edmonton and Winnipeg do is actually debatable considering neither has a building over 500 ft). But when you say that Calgary and Jacksonville are comparably-sized metros but Calgary boasts a much larger skyline, it loses validity as a comparison because taken out of their contexts, they really are not comparably-sized metros. Jacksonville, though having a larger metro area than Calgary, in reality functions as a smaller city in the US than Calgary does in Canada.
