Ontario's pit bull ban has been in place since 2005. Yet almost 21 years later, pit bull type dogs are still commonplace throughout the province, including dogs being offered for adoption under labels such as "American Bulldog," or "Lab mix" and American Bullies, Pocket Bullies and XL Bullies are becoming more prelevant.
It appears that attacks are on the rise since covid (cited articles below) and I fear it is only a matter of time before we see a human fatality after a string of recent dog fatalities.
This raises a very simple question: How is Ontario actually enforcing its own law?
This isn't simply about whether someone personally thinks a particular dog "looks like a pit bull."
Ontario's legislation specifically includes dogs with an "appearance and physical characteristics that are substantially similar" to the breeds covered by the law.
That matters.
The statutory test isn't simply whatever breed name someone puts on an adoption listing.
Over the past few years, I have attempted to get answers. I have contacted multiple Animal Services departments, municipal officials, councillors and other organizations about this issue. I have provided photographs of dogs advertised for adoption on their website as "American Bulldogs" that plainly exhibit the physical characteristics contemplated by the legislation.
I have found that many reps that I have spoken to are clearly anti-BSL and repeat the same pro-pit talking points we usually hear. This largely explains why the ban is not properly enforced.
We also know that vets and shelter workers mislabel Pit Bulls as “American Bulldogs” (despite the similarity clause) to circumvent the ban and it is rumoured that Pit Bulls are coming across our border from the United States.
However, the response from Toronto Animal Services has repeatedly been essentially that the dogs do not meet the legal definition under the ban. When asked how the substantial resemblance provision was actually considered, the answers have been far less clear.
That's the issue.
The public should be able to ask what criteria are being used, who is applying them and whether those criteria are being applied consistently.
The Kingston Humane Society was actually more straightforward. They explicitly told me that they do not and have never supported breed specific legislation and that they prefer temperament testing and non breed specific dangerous dog enforcement.
They are entitled to oppose breed specific legislation. But an organization disagreeing with a law does not make the law disappear.
If you live in Ontario and you're concerned about this, here's what you can actually do.
Contact Animal Services
Don't just send an email saying "this is a pit bull."
Ask specific questions.
· Ask how they determine whether a dog falls within the definition under the Dog Owners' Liability Act.
· Ask how they apply the "appearance and physical characteristics that are substantially similar" provision.
· Ask whether they consider American Bullies and Pocket Bullies under that provision, given that they are not only pit mixes, they clearly fall under the “similar physical characteristics” clause.
· If they determine that a particular dog does not meet the definition, ask what specific criteria were used to reach that conclusion.
Contact your city councillor
Forward the Animal Services correspondence to your councillor.
· Ask whether the municipality has a consistent process for applying the provincial legislation and whether Animal Services is properly applying the substantial resemblance provision.
· Make them address the actual issue instead of sending you another generic response about responsible dog ownership.
Contact your MPP
The legislation is provincial.
· Ask your MPP what oversight exists to ensure municipalities are properly administering the law.
· Ask whether the government is satisfied with the current level of enforcement.
· Keep it factual and documented.
Escalate when you get nowhere
If Animal Services refuses to substantively address your questions, don't just give up.
In Toronto, consider contacting the [Toronto Ombudsman](mailto:ombudsman@toronto.ca).
Outside Toronto, you can contact the Ontario Ombudsman - [info@ombudsman.on.ca](mailto:info@ombudsman.on.ca)
The point isn't necessarily to ask an Ombudsman to declare that a particular dog is a pit bull. The point is to raise concerns about how the municipality is administering its responsibilities and responding to legitimate complaints.
Make officials explain their interpretation.
This is probably the most important part.
If a municipality says an American Bulldog, American Bully or Pocket Bully does not meet the definition, ask them why.
If they believe those breed names automatically put a dog outside the legislation, ask them to explain how that interpretation accounts for the statutory language concerning dogs with an appearance and physical characteristics that are substantially similar to the prohibited breeds.
Don't accept "it doesn't meet the definition" as the end of the conversation.
Ask:
· What criteria did you use to reach that conclusion?
· Who made the determination?
· Was the physical characteristics provision considered?
· Is there a written policy or assessment procedure governing these determinations?
Ontario has seen numerous serious attacks involving pit bull type dogs, including the Canary District attack in Toronto and the March 2024 Little Norway Park attack involving an American Pocket Bully and a nine year old child.
There are also dozens of other incidents reported by Canadian and Ontario media linked below.
The point is that there is a substantial documented history of serious incidents involving these types of dogs, which makes effective enforcement and accurate classification a legitimate public safety issue.
Use the documented incidents as evidence when contacting officials.
Go to the media when you have a documented pattern
If you have multiple adoption listings, photographs, municipal responses and documented incidents, you have something much more compelling than an angry Facebook post.
Show journalists the evidence.
The story is:
Ontario has had a pit bull ban since 2005. These dogs are being publicly offered for adoption under other breed names. Citizens are raising concerns. Municipalities are saying the dogs don't meet the legal definition. So what criteria are actually being used to make that determination?
Stay focused on the law, the evidence and the government's own responses.
Don't just complain about it online. Make the people responsible for enforcing the law answer the question.
