This is the old Dolime quarry or also now known as the Glenchristie quarry and is located just outside of Toronto, Canada. The quarry sits at around 30 - 40 ft deep and the deeper section towards the back reaches just to about 90 ft. There is limited parking and this is a popular training site, so get there early!

This is an excellent dive site for beginners as well as for advanced training. Explore boats, cars, barges, and other assorted items, sunk & ready to be discovered!
