You're way offside on the size comparison, comparing Chicagoland (analagous to the GTA) with the City Proper Toronto (ie, excluding the GTA).
Toronto's City Proper / Metro Region size of 2.6 million / 5.6 million (2011, Statistics Canada). Chicago's City/Metro size is 2.7 million/ 9.5 million. So the City Proper size is comparable, but Chicago has bigger suburbs.
I think 8.2M refers to New York City, not Chicago.
