Good point. Hamilton is admittedly more than a bridge distance from Toronto. Although that does give the analogy a distinct Toronto flavour. I don't think Mississauga is to Toronto what Brooklyn is to Manhattan, because Mississauga (for the most part) doesn't have that grittier urban character - it's largely sprawling suburb or 21st century "downtown", and the parts that do have that urban character (Streetsville, Port Credit) are already priced out of the budget of the young professionals and artists who are starting to do interesting things in Hamilton.
Using a NYC analogy, it's more akin to...Newark? New Haven?
But in some ways, Washington/Baltimore is the best comparison. [...]
Why must Canadians always feel the need to compare or reference themselves to Americans?
