Firstly, you're exaggerating by saying that area is "fucking disgusting". Yes, Chinatown is covered in filth year-round, but that's Chinatown. The rest of that area is pretty damn clean compared to similar American neighbourhoods I've been too. Also, any litter problem is likely because the area has more pedestrian traffic than probably anywhere else in Canada. People speeding through suburbs in cars don't leave much garbage.
Second, that neighbourhood is obviously representative of Toronto as a whole. (/sacrasm) Or, are you one of those people who rarely ventures outside a very tiny set of borders?
