Vancouver must be one of the exceptions to this. I'm from Winnipeg, which uses only Kijiji, and recently moved to Vancouver. When I was looking for an apartment, I tried Kijiji and didn't find much at all, after talking to some people I know from Vancouver, they told me to try CraigsList and that's where all the posts were. I actually prefer the cleaner interface though, Kijiji is quite cluttered in comparison.
