I know I'm kind of talking to myself in this thread, but any insight I can give I'd like to share. According to the Canadian veterinary journal. Up to 2010 from 1990 there were only 32 dog related fatalities in all of Canada. Most were determined to be mixed breed dogs, Huskies, and roaming packs of sled dogs.
You are more likely to win the lottery 3 times than you are to be killed by a dog, any dog in Canada, never mind a pit.

This is an updated list not including the pitbull related death in Quebec as its too recent to be include on the statistics.
Seems like a witch hunt.
