The death of Chinatown and other ethnic areas in the inner city of Toronto I think is a very big issue. While we can't stop change in the city, the loss of these areas from our inner city is a big problem.
With ethnic areas spread in exurban areas, it does not make it easy to go sample that culture, or even be able to stroll down a nice street.
The exurban districts just do not have the same style like the walkable inner city districts did.
But the decentralization you could say of ethnic areas is an issue.
Right now you can go downtown, and within min of downtown you can visit Chinatown, ride a streetcar out to Little India, Little Italy, greektown(which is dead now as an ethnic area), etc.
But as these places spread further out, it makes it harder for people to actually go visit these areas, and thats sad.
Theres nothing like a walkable ethnic strip, and a nice cluster of all these areas in a nice central location.
I think the problem with Toronto is we have such large immigrant populations, that its hard to keep one central location. Because of our large population, immigrants live everywhere and just built mini ethnic areas allover. Instead of say like Calgary where theres one Chinatown downtown, and thats it.
I do think TTC is to blame for part of the decline in the downtown Chinatown. If the TTC actually knew its ridership, they would be providing express bus service from northern Scarborough to Spadina Ave and downtown, every Saturday, etc. I bet if was easier to get down to Spadina, more people would do it.
But the loss of central ethnic areas is a big loss for Toronto and will make our inner city less exciting for sure.
The Chinese can built all the malls they want in Markham. There is only one place that really gives you the real chinatown feel, and thats Spadina, and no mall will ever capture that.
