In Quebec, Craigslist is virtually unknown (with maybe a little traffic in Montreal, but I'm not sure), everyone used LesPAC first, and then Kijiji when it came along. You needed to pay to post an ad on LesPAC, so it quickly lost market share when a free competitor emerged.

Both of these have a French-language version, and I believe it had a lot to do with CL's failure to get the market here.
