Toronto has some Chinatown segregation going on.
The downtown Chinatown on Spadina Ave caters more to mainland Chinese populations, and on weekends it is normal to see Chinese people from Scar commuting down by subway to Spadina Ave to hang out and shop in Chinatown.
However the Chinese population from Hong Kong will for the most part not be caught on Spadina Ave, and they tend to stick to the suburban Chinatowns they built in the suburbs.
Now of course that is a general overview and there are people from both groups who use both areas. But I have Chinese friends who have told me about that little divide between the Chinatowns.
Toronto's downtown Chinatown along Spadina Ave has a BIA now, and one of their projects is trying to get suburban Chinese residents to come back downtown to Spadina Ave, and rediscover the joys of an urban Chinatown and their so called immigration roots.
Don't know how well that is working.
Overall the suburban Chinatowns in Toronto happen to have some great food, and a friend and I always go up to Highway 7 to have some of the best dumplings you will ever taste outside of Asia.
But that being said, the suburban Chinatowns just don't have the same vibrancy and character as Chinatowns on real urban streets. So for character and atmosphere, Spadina Ave will always be more interesting.
The Chinese are not the only population suburbanizing. All cultures seem to be seeing their ethnic areas migrating to the suburbs.
Despite having one of the largest Italian populations outside of Italy, you would never know it anymore looking at inner city Toronto. The two Little Italy districts in the city are getting more and more less Italian each year, as Italian business continues to flee to the outer suburbs into strip mall little italy strips.
I do however find suburban ethnic areas much harder to navigate. On a urban strip, you can walk around and look at things and discover places.
But in the suburbs you gotta drive from strip mall to strip mall, and you really can't discover to the same degree as walking down a street. And in terms of the Italian suburban areas, its even harder, because many business are in these office park industrial areas. And unless you know there is a bakery tucked in there from an add, you will never find it just driving down the street. Which really makes it hard to get Italian culture anymore
