For those people interested, here is a comparison of highrise counts for New York, Chicago, Toronto, Vancouver, Calgary, Edmonton, Winnepeg, Ottawa and Montreal.
Chicago has the greatest scale height, 29 floors (scale height here means the number of additional floors for the number of highrises, reaching at least that number of floors, to drop by a factor of ten). Next is New York, with a scale height of 22 floors. Calgary and Toronto are almost tied, with scale heights of 19 and 18 floors respectively. Montreal is another step down, at a scale height of 15 floors, while Winnipeg and Edmonton share a low scale height of 12 floors.
Some comparative numbers:

SCALE HEIGHTS
29 Chicago
22 New York
20 Vancouver (up to 32 floors -- above that floor height it's 5)
19 Calgary
18 Toronto
15 Montreal
13 Ottawa (up to 26 floors -- above that floor height it's 4)
12 Edmonton
12 Winnipeg
A small scale height means that given a specific number of highrises with some given number of floors, there are proportionately few taller highrises, while a large scale height means that there are proportionately many taller highrises.
