There's also a chance, Williams adds, that people won't be able to get homeowner's insurance if they own a pit bull.
"Some people are in a situation where they're just panicking and don't want to pay a surrender fee, so they just decide to go and dump them off on the side of the road," Williams says.
But the most terrible price of the ban may be paid by countless shelter dogs.
"Say they're at a shelter in the Montreal area," Williams explains. "You will no longer be allowed to adopt a one - what does that mean for those animals? Will they all have to be euthanized if they're not transferred?"
