I just found Dr Ken Wolch in Scarborough in an old magazine I was going through. It says "Over 20 years of mercury free and bio-compatible dentistry. State-Of-The-Art Facility, Cosmetic Dentistry. 2863 Ellesmere Road, Suite 205, Scarborough, 416-281-4746. This was from the Vitality Magazine, December 2003/January 2004. Not sure if he is still there but I am going to give him a call.
