REALLY strange choice of data point for Toronto -- it uses a much smaller land area than for the US cities. Greater Toronto Area - 7,124 km^2 Chicago Metro Area - 28,120 km^2 Houston Metro Area - 26,061 km^2 Dallas-Fort Worth - 24,059 km^2 Washington Metro - 14,412 km^2 Philadelphia Metro - 13,256 km^2 A much more apples-to-apples comparison would be the Golden Horseshoe (7.005 million / 10,097 km^2), or Greater Golden Horseshoe (8.759 million / 31,561 km^2). I believe that Chicago's population is also stagnant, whereas the GHA has grew 4.5% from 2006-2011, so extrapolating to 2016 would put it at 9.1 million. Still smaller than the Chicago metro area, but not by a lot.
