List of Legal Pets in Ontario 2026: What You Can Own and the Supplies You'll Need

Ontario has no province-wide list of banned pets. Legality is decided by municipal bylaw, so dogs, cats, rabbits, guinea pigs, hamsters, gerbils, ferrets, most pet birds and aquarium fish are legal almost everywhere in the province, while large constrictor snakes, venomous reptiles, primates and big cats are prohibited in Toronto and most GTA municipalities.

That split matters more than most new owners expect. The same animal can be perfectly legal on one side of a city boundary and a bylaw violation on the other. Once you've confirmed your pet is allowed where you live, the next job is practical — food, bowls, litter, leashes, enrichment. If you already know what you're bringing home, you can shop dog food and supplies or browse cat food and supplies and skip ahead.

How Ontario pet ownership laws actually work

Ontario regulates animal welfare provincially but pet ownership locally. The Provincial Animal Welfare Services Act, 2019 (PAWS) sets standards of care enforced by provincial inspectors, while the Dog Owners' Liability Act governs dangerous dogs. Everything else — which species you may keep, how many, and whether you need a licence — comes from your city's animal bylaw.

Toronto's Municipal Code Chapter 349 is the reference point for most of the GTA. It permits a maximum of 3 dogs and 6 cats per dwelling unit, requires licensing for both dogs and cats, and carries a schedule of prohibited animals that covers roughly 20 categories of wildlife and exotics. Mississauga, Brampton, Markham and Vaughan each maintain their own schedules, and they don't match Toronto's line for line. Customers often ask us whether a provincial permit exists that overrides a municipal ban — it doesn't, outside of licensed zoos, research facilities and wildlife rehabilitators.

Before you commit to any animal, call your municipal animal services line and ask two questions: is this species permitted, and is there a household limit? The Canadian Veterinary Medical Association also publishes guidance on species suitability, and the American Veterinary Medical Association maintains position statements on exotic and wild animals kept as pets. For a city-by-city breakdown written for GTA readers, see our companion guide on what pets are legal to own in Ontario.

Here's the broad picture of legal pets in Ontario by category:

• Dogs — Legal province-wide. Licensing required in most cities; breed restrictions apply under the Dog Owners' Liability Act.
• Cats — Legal everywhere; Toronto caps households at 6 and requires a licence.
• Rabbits — Legal in nearly all municipalities, usually classed as small companion animals.
• Small rodents — Hamsters, gerbils, guinea pigs, rats and mice are broadly permitted.
• Ferrets — Legal in Toronto and much of the GTA, prohibited in a handful of Ontario municipalities.
• Pet birds — Budgies, cockatiels, canaries, finches and most parrots are allowed; some cities restrict pigeons and poultry.
• Fish and aquatic species — Almost always legal, subject to federal and provincial invasive-species rules.

Which exotic pets are restricted under Ontario bylaws?

Large constrictors, venomous reptiles, primates, wild cats, crocodilians and wolf hybrids are prohibited in Toronto and most surrounding municipalities. Because Ontario has no provincial ban list, these ontario exotic pet rules exist only at the city level — which is why a species banned in Toronto may be unregulated in a smaller township 40 km away.

Commonly restricted animals across GTA bylaws include:

• Constrictor snakes — Pythons and boas above a set adult length (often 3 metres) are prohibited.
• Venomous reptiles, spiders and scorpions — Banned almost universally.
• Primates — Monkeys, lemurs and apes are prohibited across the GTA.
• Exotic felines — Servals, caracals and savannah cats below a certain generation are widely restricted.
• Wild canids — Foxes and wolfdog hybrids face bans or permit requirements in many cities.
• Large lizards and crocodilians — Monitors over a set size, caimans and alligators are prohibited.

The ASPCA notes that most exotic species have husbandry, temperature and dietary requirements a typical household can't sustain, which is a large part of why municipalities restrict them. Worth being clear: Ashario Pets is a supply store. We don't sell live animals of any kind — no puppies, kittens, fish, birds or reptiles. What we stock is the food, supplements, toys and accessories that legal companion animals need every single day.

Related questions about legal pets in Ontario

Are ferrets legal to own in Toronto?

Yes. Ferrets are legal in Toronto and are not listed on the city's prohibited animals schedule. A small number of Ontario municipalities still ban them outright, so confirm with your own animal services office before buying a cage or carrier. Ferrets need a high-protein, high-fat diet — typically above 32% protein content and 18% fat content.

Do I need a licence for my dog or cat in Ontario?

In most Ontario cities, yes. Toronto requires licences for dogs and cats over three months old, renewed annually, with reduced fees for spayed or neutered animals. Licensing links your pet to your contact details in the municipal database, which is the fastest route home if they slip a leash. Microchipping isn't mandatory province-wide but is strongly recommended.

How many pets can I legally keep in one household?

Limits are municipal. Toronto permits up to 3 dogs and 6 cats per dwelling unit, with a combined cap that also counts other companion animals. Mississauga and Brampton set their own numbers, generally in the 3-to-4-dog range. Exceeding the limit is a bylaw offence even if every animal is well cared for.

Can a landlord ban pets in Ontario rentals?

Under section 14 of Ontario's Residential Tenancies Act, "no pets" clauses in residential leases are void and unenforceable. A landlord can still apply to the Landlord and Tenant Board if an animal causes damage, serious allergic reactions, or danger to others. Condominium corporations operate under different rules and can enforce pet restrictions in their declarations.

Are hedgehogs and sugar gliders legal in Ontario?

African pygmy hedgehogs are legal in Toronto but prohibited under some neighbouring municipal bylaws, and sugar gliders fall into the same patchwork. Both are insectivores or omnivores with specialised diets that fall outside standard dog and cat nutrition, so plan your sourcing before you commit. Always verify your city's schedule first.

What supplies you'll actually need once your pet is legal

Every legal companion animal in Ontario needs three things: a complete-and-balanced diet meeting AAFCO standards, species-appropriate accessories, and daily enrichment. Nutrition is where the budget should start, because it's the only one of the three your pet consumes every day of its life.

Check the guaranteed analysis panel and the AAFCO statement on any bag or can. Under AAFCO nutrient profiles, growth and reproduction diets require a minimum of 22.5% protein content on a dry-matter basis for dogs, while adult maintenance requires 18%. Cats sit higher — 30% for growth, 26% for adult maintenance — and need supplemental taurine, with minimums of 0.10% in dry food and 0.20% in canned. The modernized pet food label regulation that AAFCO adopted in 2024 is phasing in a clearer nutrition panel over the next several years, so expect packaging to look different as brands update.

Our nutrition team at the North York store recommends matching life-stage formulation to your pet's actual age rather than buying an all-life-stages bag by default — a 12-week puppy and a 10-year-old dog have genuinely different calorie and mineral needs. Pet owners tell us the most common early mistake is overfeeding: most adult dogs need roughly 30 kcal per pound of body weight daily, which is far less food than the scoop suggests for a small dog.

Starting with a dog

You'll need daily food, bowls, a collar and leash, grooming tools and durable toys. Our selection of dry dog food includes Acana, Orijen, Fromm, Go! Solutions and Oven-Baked Tradition, while Big Country Raw, Stella & Chewy's and Primal anchor the raw dog food shelves — raw feeders typically serve 2–3% of body weight daily, split across two meals. Add dog treats from Crumps' Naturals or Greenies for training, plus joint support with glucosamine and omega-3 if you've got a large breed. Winter in the GTA is hard on paws, so a balm and a towel by the door earn their keep between salt-covered sidewalk walks and trail loops through G. Ross Lord Park.

Starting with a cat

Cats are obligate carnivores, so high-moisture diets do real work for urinary health. Brands like Weruva, Tiki Cat, Caru and Inaba fill the wet cat food aisle, and a quality litter from World's Best Cat Litter, OdourLock or Naturally Fresh handles the other end of the equation — the standard rule is one cat litter box per cat, plus one spare. Round it out with vertical furniture and rotating cat toys, and review our cat wellness guidance for supplements containing probiotics or omega-3.

Whatever species you choose, bring any health question to a licensed veterinarian — diet transitions for pets with kidney, liver or pancreatic conditions should be made under veterinary supervision, not from a label alone.

Visit us at 1111A Finch Ave W, Unit 2, North York, ON M3J 2P7 — we're open 7 AM to 11 PM daily, and delivery is available across the GTA through apps like Uber Eats. You can also contact our store team with a nutrition question before you shop.

Quick summary: Ontario sets pet ownership rules through municipal bylaws rather than a provincial banned-species list, so dogs, cats, rabbits, small rodents, ferrets, birds and fish are legal nearly everywhere while large constrictors, venomous reptiles, primates and wild cats are prohibited across the GTA. Always confirm with your city's animal services office before acquiring any unusual species. Once your pet is home, start with an AAFCO-compliant, life-stage-appropriate diet and build out accessories from there.
