Finding A Rental For Next Year

Are there any lesser-known classified ad websites or rental companies that someone who is currently looking for a place should know about?

I'm currently looking for a room to rent in a house, after plans to move in with someone else fell apart and left me with no roomies to search for a place with. I feel like I've exhausted my options with Kijiji/UWO Off-Campus Listings/Exclusive Rentals/etc and I still don't have a place to live :(

(If any of you are looking for a roommate at your house, my maximum budget is $450 including utilities, but paying extra for internet is fine!)
