🚫 Breed bans
Province-wide ban
Yes. Since 2005 Ontario’s Dog Owners’ Liability Act bans pit bulls — Pit Bull Terriers, Staffordshire Bull Terriers, American Staffordshire Terriers, American Pit Bull Terriers and dogs that look like them. Pit bulls already living in Ontario then could stay as “restricted” dogs: leashed, muzzled and sterilised.
Yes. Under the Dog Owners’ Liability Act the owner is liable for damages from a bite or attack whether or not they knew the dog was dangerous; damages are reduced if the victim was partly at fault.
Yes. Ontario Regulation 567 requires dogs, cats and ferrets 3 months and older to be vaccinated against rabies and kept up to date — including indoor cats.
No provincial ban, but Toronto requires pet shops to get dogs and cats only from shelters and rescues, and cities such as Cambridge ban selling them for profit.
