There are some amazing DH runs not far from here. Hop on your bike, ride north and then hang a left at Thunder Bay. Keep heading west until you hit Whistler....
I know there are some guys working on a DH run in behind Brock University. There also used to be some good stunts and stuff on the Tremont Trail, which you access in behind the Pen Centre by riding up Tremont Street I believe it's called. If you go into Liberty Bicycles they have a good guide book called Rider Mel's Guide to MTBing in Ontario. The Tremont Loop is in there, as well as other maps of the area.
