I don't remember the actual names of the breeders I picked up my gargoyles from, but I bought them from breeders at the Toronto Reptile Expo in Missassauga. They have regular shows with the next one being in February and again in April as well as several during the summer. For more info on the Toronto shows, you can go to their website: www.reptileexpo.ca
There is a guy in Montreal that has gargoyles though I am not sure if he is breeding them yet. If you want his info, send me an email (just click on my name and you can send me a message that way)
If you don't live at all in the Toronto/Montreal areas, check the 'Events' link above (not far below the kingsnake header) for upcoming reptile shows in your area.
