"4. Toronto is the 3rd largest North American city;" Not quite, that's only technically correct, due to the fact that major urban areas in the US don't 'incorporate' into major cities. It's better to compare 'greater urban areas' with other regions. On that basis, it's not so big. LA, Chicago, Dallas Ft/Worth, NYC all bigger, with Boston, Houston, Bay Area, DC, Seattle, (even Atlanta) about the same size. There's a few more on that list. America is very populous and just outside many urban centres are vastly populated areas of slightly less density. Esp. in the North East.
