Not a great experience with this one. I typed "Toronto" into the location, and the results were:

1-3: Toronto, ON 4-7: Pittsburgh, PA 8-11: null, Ohio 12-25: Toronto, ON

I also clicked to half a dozen positions and all but one returned "Sorry, this position is not available".

Finally, I noticed a few postings for "Reputable Company looking for immediate hire" (yes, this was the description). I know this tool just scrapes job boards, but that sort of vague description really hurts my confidence in the results.
