Montreal is a very workable city to share with a dog, once you know a few local rules and practical details.

Some are easy to miss. Dogs need an annual city licence, larger dogs have an extra harness or halter requirement, pet dogs can use the métro under specific conditions, and Montreal has its own limits on how many pets can live in one home.

Then there are the things you usually only think about when you need them, like where to find a licensed veterinarian or which emergency hospitals are open around the clock.

This guide pulls the most useful Montreal-specific information into one place.

Every dog living in Montreal needs a city licence, and that licence must be renewed each year. The physical tag is issued for life, so you keep the same tag when you renew. Your dog is expected to wear it even if they’re microchipped.

Dogs over six months are generally required to be microchipped and sterilized, although some exceptions apply.

In public places, dogs must be kept on a leash no longer than 1.85 metres. Dogs weighing 20 kg or more must also wear a harness or halter attached to the leash.

The city also requires guardians to pick up waste, keep dogs under control, and avoid tying pets to trees or street furniture. Dogs aren’t allowed on playing fields or to drink directly from public fountains.

For current licensing details and exceptions, I’d check the City of Montreal directly.

This one has caused plenty of confusion, so it’s worth spelling out.

Montreal currently allows up to 8 pets in total, with these limits:

• a maximum of 3 dogs
• a combined maximum of 4 dogs and cats

So, for example, the city allows:

• 3 dogs
• 3 dogs and 1 cat
• 2 dogs and 2 cats
• 1 dog and 3 cats
• 4 cats

Fish don’t count toward the total. Foster-family exceptions apply in some cases, although the three-dog maximum still remains.

You can check the city’s current Pets: Authorized species and numbers page here whenever you need to verify the rule.

Pet dogs are allowed on the Montréal métro under specific conditions.

If your dog is outside a carrier, they need to wear a muzzle from the time they enter the station until they leave, and you need to keep them on a leash with no more than 1.25 metres of slack. Only one dog per customer is permitted, and dogs can’t take escalators, or sit on métro seats or platform benches.

Access is limited to designated times on weekdays, with broader access on weekends, holidays and during the STM’s summer period.

The bus rules are stricter. Pet dogs and other animals need to be in a closed carrier designed for transport when riding the bus. Guide and assistance dogs are exempt from those restrictions.

If you plan to use the métro regularly with your dog, it can help to practise the component skills first: comfortable muzzle wear, moving through busy entrances, riding elevators or stairs, and settling around unfamiliar people and noise.

Montreal has more than 65 dog parks, giving guardians plenty of designated off-leash options.

The city’s dog-park rules include:

• a maximum of two dogs per person
• dogs must stay leashed until they’re inside
• guardians must supervise and control their dogs
• food for dogs isn’t allowed
• toys and sticks can’t be used when other dogs are present
• females in heat and dogs showing symptoms of illness shouldn’t enter
• children under 12 are discouraged from entering
• vaccination and parasite prevention are recommended

One detail that surprises people: Montreal allows licensed professional dog walkers to walk up to eight dogs at a time, but they’re still limited to two dogs inside a dog park.

Dog parks can be useful for dogs who genuinely enjoy loose group play. Watch your dog’s body language throughout the visit, especially around entrances, greetings and changes in play. Plenty of dogs are happier with familiar playmates, quiet sniffing walks, or more space around unfamiliar dogs.

The City of Montreal also has a dog-park finder if you want to check options near home.

If you rent, check your lease before bringing home a dog or signing for a new apartment.

In Quebec, landlords can generally prohibit pets in a building. The lease or building rules usually state whether animals are allowed, although exceptions can apply, including animals that help someone cope with a disability.

The building itself matters too. A third-floor walk-up might be perfectly manageable with one adult dog and much harder with a young puppy who needs frequent toilet trips, a senior dog, or a dog recovering from surgery.

I’d also look at:

• elevator access
• hallway and lobby traffic
• noise through adjoining walls
• nearby green space
• where your dog will toilet
• how far you need to walk before reaching a quieter area
• whether entrances force close encounters with other dogs

Those details can make a noticeable difference if you live with a fearful, reactive, elderly or very young dog.

If you don’t already have a regular clinic, the Ordre des médecins vétérinaires du Québec (OMVQ) has a public directory where you can search for licensed veterinarians and verify that someone is authorized to practise in Quebec.

It’s useful to find a regular vet before you need urgent care. Ask whether they’re accepting new clients, how they handle same-day concerns, and where they refer clients after hours.

Keep your dog’s vaccination history, medication list and important medical records somewhere easy to access, especially if you change clinics or need emergency care.

Montreal has two major 24/7 emergency and referral options that are useful to know in advance.

Centre Vétérinaire Montréal
1901 boul. De Maisonneuve Est
Montréal, QC H2K 4P4
438-387-2746
24/7 emergency and referral care.

CENTREDMVET Montréal
2300 54th Avenue
Montréal (Lachine), QC H8T 3R2
514-633-8888
24/7 emergency and specialty care, with walk-in emergency service and no appointment required.

It’s worth saving both in your phone. Depending on where you live, traffic and time of day, one may be considerably easier to reach than the other.

A humid Montreal summer can change your walking routine quickly.

Earlier mornings and later evenings are usually more comfortable, and shade, water and shorter outings become especially useful on hotter days. Pavement, concrete and artificial turf can also heat up much more than the surrounding air.

Watch the dog in front of you. Slowing down, persistent panting, seeking shade or losing interest in continuing are all good reasons to change the plan.

On very hot days, indoor scent work, food searches, enrichment and shorter training sessions can help meet behavioural needs with less physical demand.

Winter brings a completely different set of challenges.

Road salt and de-icing products can irritate paws, especially when snow and grit build up between the toes. Some dogs do well with boots, while others need shorter outings and a rinse or wipe-down when they come back inside.

Cold tolerance varies a lot. Coat type, age, health, body condition and activity all affect how comfortable a dog will be outside.

Ice can also be difficult for senior dogs and dogs with mobility issues. Cleared routes and good footing can make outings much easier.

Once the local rules are familiar, most of the rest is everyday planning: choosing the route that works for your dog, knowing where they can be off leash, checking transit rules before a trip, and adjusting outings for the weather.

A little local knowledge goes a long way in a city where dog life can look very different depending on the neighbourhood, the season and the dog sharing it with you.
