I have found an ad site that is new, new to me anyway, that I think beats Craigslist in ease of use, especially if you are the travelling kind of guy who visits many cities and might want to look for SP's while there. All the cities it covers are listed on one page as you can see, so it's not necessary to search for a site for that city as you do on Craigslist.
If you click on Toronto, essentially the actual site that NOW uses for the local TS ads is what comes up. I suppose it is linked to some association of newspapers.
Here is the main page:
