Saint-Lambert Short-Term Rental Regulations: A 2026 Guide For Airbnb Hosts

Do you own a place in Saint-Lambert and you're weighing whether to put it on Airbnb or Vrbo? Well, the good news is that hosting is legal here, and Quebec law stops the city from banning it outright in a home you live in. Saint-Lambert sits on Montreal's South Shore, in the Montérégie region of Quebec, and like every Quebec municipality it works underneath a provincial statute that sets the floor.

The catch is that the city treats two very different businesses under one heading. Renting the home you live in is allowed on every street in town, though only for stays of 3 to 30 days, and only 60 days a year if you're handing over the whole place while you're away. Running a furnished unit purely as a rental is a commercial use, and zoning by-law 2024-215 permits that in 5 of the city's 153 zones. None of them are residential.

So let's walk through what it takes to do this properly in 2026: which by-law actually governs you, the two separate permissions you'll need and the order they go in, what each one costs, the three taxes attached to a night's stay, how enforcement works, and who to call when something doesn't fit your address. Every figure below comes from Saint-Lambert's own by-laws or Quebec's statutes, checked in July 2026. Before any of it, run the property through BNBCalc to see whether a legal 60-day season clears your carrying costs.

What are Short-Term Rental (Airbnb, VRBO) Regulations in Saint-Lambert, Canada?

That 60-day figure is municipal, but the permission underneath it is provincial, so two layers of law decide what you can do here and separating them explains most of the confusion.

The bottom layer is the Tourist Accommodation Act, which covers any establishment offering a unit to tourists "for a period not exceeding 31 days". Section 4 makes registration mandatory before you operate, and section 5 says the application has to arrive with a document from the municipality establishing that the use doesn't contravene local planning by-laws. Quebec built the city into its own approval process, in other words. Miss the municipal step and the provincial one can't finish.

Section 23 is the part that protects you. No municipal by-law made under the land use planning act may prohibit a tourist accommodation establishment offering accommodation in the operator's own principal residence, by a single reservation, to one person or one group of related persons at a time, with no meals served. A municipality can claw that back, mind you, but only through a zoning or conditional-use amendment carried under the referendum process, and the statute halves the number of signatures needed to force that referendum. Saint-Lambert hasn't gone down that road.

The top layer is the city's zoning by-law, in force since 24 May 2024 and administratively codified on 25 November 2025. It opens three doors, and they're not the same size at all:

• Hébergement touristique de type résidence principale, a complementary use to housing, authorised across the entire territory.
• Gîte touristique (class C-2), a bed and breakfast where the owner or occupant lives in the building, permitted in zones CA-1, CB-1, CB-4, MI-2, MI-5 and MI-6.
• Résidence de tourisme (class C-3), a whole furnished unit rented commercially, permitted in zones CA-1, MI-1, MI-2, MI-7 and MI-8.

The first door is the one nearly everyone reading this will use, and it comes with five conditions written into chapter 3 of the by-law.

A booking for the same group has to run at least 3 days and no more than 30 consecutive days. Renting the entire dwelling without its usual residents present is capped at 60 days per calendar year. You can offer the whole dwelling, or a single room with its own bathroom. The stay has to happen inside the main building, never in a garage, coach house or other accessory building. And your guests can't use an outdoor fireplace on the property.

Keep in mind that the by-law counts in days rather than nights, so make sure you check the wording against how your calendar is set up. Either way, the one-night and two-night bookings that are the bread and butter of a suburb this close to Montreal aren't available to you at all.

Starting a Short-Term Rental Business in Saint-Lambert

Those five conditions read like housekeeping until you try to build an investment case on top of them, and then they bite.

Unfortunately for most people reading this, buying a condo or a duplex in Saint-Lambert to run as a full-time Airbnb isn't a business the by-law allows. A résidence de tourisme is a principal commercial use, and the usage grids in Annexe 2 authorise class C-3 in exactly five zones out of 153. Every RA, RB, RC, RD and RE zone, which is to say every residential street in the city, carries no dot on that row. No permit unlocks it, because the issue isn't paperwork. It's the zone your address sits in.

Where the use is allowed, the conditions are strict in their own way. The by-law requires the entire dwelling to be available for rental only, with no residential occupancy at all, rented to one person or one group of related persons at a time, inside the main building, with one parking space per rented room. If an outdoor fireplace exists on the lot, nobody may use it during a rental period.

The provincial data shows how that plays out. Quebec's open-data extract of registered chalets, apartments and tourist residences lists 13,616 establishments province-wide and 166 in the Montérégie tourist region, of which zero are in Saint-Lambert. Longueuil next door has 19, Châteauguay 10. Registered gîtes tell the same story: 581 across Quebec, 14 in Montérégie, none here. Whatever the theoretical five zones allow, nobody has actually built the commercial version in this city.

What's left is genuinely your own home, so model a spare room or a 60-day season in BNBCalc rather than a year-round unit. Two more gates sit in front of even that.

Tenants need a lease that permits tourist accommodation, or the owner's written authorisation, and the city wants a copy of the lease plus that consent with the application. In a divided co-ownership, the declaration itself has to allow the use, or the syndicate has to authorise it in writing. Do check your condo declaration before you spend a dollar, since a syndicate that says no ends the conversation there.

Short-Term Rental Licensing Requirement in Saint-Lambert

Assuming your address and your building both clear all that, you'll still need two separate permissions, and the order matters more than anything else in this guide.

The city goes first. Under the permits and certificates by-law, a certificat d'occupation is required for a principal-residence tourist accommodation complementary use, and it's listed there alongside commercial and industrial occupancies rather than buried in a residential annex. The 2026 fee schedule prices an occupancy certificate at $200 as of July 2026, whether the line applied is a non-residential use or a home-based practice. Changing the use, the owner or the address later costs another $200.

Once the file is complete, the by-law tells the officer to check it against the zoning and construction by-laws and issue the certificate without delay, or refuse it in writing with reasons. There's no council vote and no committee. Watch the clock on corrections, though: when the city asks for missing or corrected documents, you get 6 months to supply them before the application lapses entirely and you start over.

Provincial registration comes second, and Quebec runs it through the Corporation de l'industrie touristique du Québec. The Tourist Accommodation Regulation sets the fee at $54 for a principal residence establishment, $131 for youth accommodation and $156 for a general establishment, with renewal priced identically, and the Quebec government's registration page confirms those same amounts as the 2026 fees. A registration runs 12 months, and the renewal application is due in the 60 days before it ends.

Then comes the detail that catches people. Saint-Lambert's permits by-law requires you to hand your provincial registration back to the city within 60 days of the occupancy certificate being issued, and says flatly that the certificate is null and void if you don't. So the sequence is city certificate, provincial registration, then proof back to the city inside two months. Miss the last step and the first one evaporates. Don't forget that the clock runs from the day the certificate is issued, not from your first booking.

Three ongoing obligations ride along with the registration itself:

• Insurance. You have to take out and maintain civil liability insurance of at least $2,000,000 per claim covering bodily injury and property damage caused in the course of operating.
• Advertising. The registration number goes in any advertising promoting the establishment and on any website used to operate it, and you have to send the registration certificate to every platform you list on.
• Display. The certificate goes up in full view of the public at the main entrance, or at the entrance to the building where the immovable holds two or more residential units.

Registration is also personal to you and to that address. Section 7 of the Act bars transferring it, so a buyer starts fresh, and the Minister may refuse a registration outright where the applicant was found guilty in the previous three years of an offence under the Act or under related legislation like the Building Act or the Consumer Protection Act.

Required Documents for Saint-Lambert Short-Term Rentals

Since that $200 doesn't come back and the six-month correction window is easy to burn, it's worth assembling both files before you open either application.

For the city, the occupancy certificate application asks for your full contact details, a power of attorney if you're not the owner, and the syndicate's authorisation in a divided co-ownership. Tenants add a copy of the lease and the owner's written authorisation. Then come the business name and a description of the activity, a parking table demonstrating compliance, and plans showing the floor area the use will occupy.

On top of that, a tourist accommodation application carries three extras:

• A copy of the registration issued under the Tourist Accommodation Act, if you already hold one when you file.
• A description of the unit you're renting: floor area, number of rooms, beds or suites, and how many people it sleeps.
• A description of the services offered, including meals, self-catering and any activities.

The principal-residence route adds a sworn statement of its own. You declare that the operator is a natural person, that this is the residence where that person habitually lives and centres their family and social activities, and that its address is the one they give to most government departments and bodies. That's the same test the Act uses, so don't treat it as a formality.

The provincial file wants a different stack: proof of ownership (title or a municipal or school tax account) or the lease, the co-ownership or landlord authorisation, proof of the $2,000,000 liability policy, indoor and outdoor photographs matching what you plan to publish, a declaration of your accommodation offering covering unit types, capacity, facilities, accessibility, pets, operating season, activities, rates and payment methods, and the municipal conformity document. The CITQ's own process page is blunt about that last one: the municipal compliance step must be completed before the registration application.

Saint-Lambert Short-Term Rental Taxes

Assuming you get through all that and are able to start hosting, there's still tax to deal with, and three charges can attach to a single night in Saint-Lambert. The rates are provincial and federal. The city adds nothing of its own, since there's no accommodation tax anywhere in Saint-Lambert's 2026 taxation by-law.

Charge	Rate	Collected by
Tax on lodging	3.5% of the price of the overnight stay	The digital platform where it's a registered operator, otherwise you, remitted to Revenu Québec
GST	5%	You if you're registered, otherwise the accommodation platform
QST	9.975%	You if you're registered, otherwise the accommodation platform

The tax on lodging is the one people forget. Section 541.24 of the Act respecting the Québec sales tax charges 3.5% of the value of the consideration for an overnight stay in a prescribed establishment situated in a prescribed tourist region, and the regulation under that Act does the prescribing. Principal residence and general tourist accommodation establishments are both covered, and Schedule II.2 lists Montérégie as a prescribed region with Saint-Lambert named inside it.

Where the supply runs through a digital accommodation platform that's a registrant, the same 3.5% applies through the platform. That's why the line item tends to show up on an Airbnb payout summary rather than on a form you file yourself.

Federal and provincial sales tax sit on top. The Canada Revenue Agency's guidance on platform-based short-term accommodation applies GST to accommodation occupied for less than one month costing more than $20 a night, at 5% in Quebec, with QST of 9.975% alongside it under section 16 of the sales tax act. A host who's registered for GST/QST charges and remits it themselves, including on platform bookings. A host who isn't registered has the platform operator collect instead, and registration generally becomes mandatory once taxable supplies pass $30,000 over 12 months.

One more federal rule can cost you far more than any of these rates. Section 67.7 of the Income Tax Act denies deductions for a non-compliant short-term rental, meaning one operated where the rules don't permit it or one that doesn't meet every registration, licensing and permit requirement. The denial is proportional, calculated on non-compliant days over total short-term rental days. So an unregistered season in Saint-Lambert doesn't only expose you to municipal and provincial fines. It can also strip the mortgage interest, utilities and depreciation out of your return for those days.

Canada Wide Short-Term Rental Rules

That deduction rule is the closest thing Canada has to a national short-term rental law, which tells you how this country handles the file generally.

There's no federal statute registering, licensing or capping short-term rentals. Ottawa touches the sector through tax alone: section 67.7 for deductions, Part XX of the Income Tax Act making platforms report host and property data to the CRA, and GST/HST on the stay itself. Everything operational is devolved twice over, first to the provinces and then to the municipalities.

Quebec is one of only four provinces with a registry of its own. British Columbia runs the strictest regime under its Short-Term Rental Accommodations Act, limiting most hosts to a principal residence plus one secondary suite in communities over 10,000. Nova Scotia registers everything let for 28 days or less, with fees that climb into the thousands for commercial operators. Newfoundland and Labrador registers hosts free of charge. Ontario, Alberta, Manitoba and Saskatchewan have no provincial registry at all, which leaves city by-laws doing the entire job.

Be aware that the same words mean different things across those borders. A "short-term rental" is under 90 consecutive days for the federal deduction rule, 31 days or fewer under Quebec's Act, 30 consecutive days or fewer for the group-stay limit in Saint-Lambert's zoning by-law, and less than one month for GST purposes. If you operate in more than one province, the Canada market page is a useful place to see where the returns justify learning a second rulebook.

Does Saint-Lambert Strictly Enforce STR Rules?

Those definitions matter because both governments can act on the same listing, and in Quebec the two enforcement systems are wired together.

Start with the city. The zoning by-law carries a penalty written specifically for this: anyone who offers an accommodation unit inside a tourist accommodation establishment for rent without having first obtained the certificate commits an offence and is liable to a fine of $500 to $1,000 as an individual, or $1,000 to $2,000 as a company. A repeat runs $1,000 to $2,000 and $1,750 to $4,000.

That's not a one-time fine either. Each day the offence continues counts as a separate offence, which is exactly where an owner who leaves the listing up gets badly hurt.

The permits by-law adds its own $1,000 and $2,000 penalties, doubled on a repeat. Underneath both sits the nuisance by-law, which prohibits noise that disturbs the neighbourhood at any hour, plus any noise reaching 50 decibels at the property line, at $100 to $1,000 for a first offence.

The provincial fines are an order of magnitude larger. Operating an unregistered establishment, or putting a false, inaccurate or expired registration number in a listing, draws $2,500 to $25,000 for an individual and $5,000 to $50,000 for anyone else. Operating after a registration has been refused, suspended or cancelled runs $5,000 to $50,000 and $10,000 to $100,000. Platforms carry the same exposure for advertising an unregistered offering, and the Act separately obliges them to verify that the number and expiry date in a listing belong to a registration that's in force. Second offences double these minimums and maximums, and subsequent ones triple them.

The wiring between the two is the piece worth understanding. Under section 12 of the Act and section 10 of its regulation, a municipality can ask the Minister to suspend or cancel a registration once the operator has been convicted of at least two municipal offences on uses, nuisances, sanitation or safety in a 12-month period. The same applies once the guests of a principal-residence establishment have picked up two such convictions.

The Minister then suspends for two months, then for six months on a second request, then cancels. So two noise tickets from a party weekend aren't a nuisance in the abstract. They're a step toward losing the registration your listing depends on.

How hard the city itself pushes is the part I can't tell you. Saint-Lambert publishes no short-term rental page, no inspection statistics and no enforcement press releases, so anyone claiming a number for it is guessing. What the records do show is that the register of registered establishments is public and searchable by address, platforms must verify the number before advertising, and the province shares establishment data with municipalities on request. Enforcement here doesn't depend on an inspector spotting a suitcase.

How to Start a Short-Term Rental Business in Saint-Lambert

Given how the two systems feed each other, the sequence below saves you the most common way this goes wrong, which is paying the province before the city has said yes.

1. Check your zone first. Call urbanisme with your address and ask which zone you're in and whether class C-3 is authorised there. Assuming it isn't, the only route open to you is hosting inside your own principal residence.
2. Confirm your building permits it. Read your declaration of co-ownership or your lease, and get the syndicate's or the owner's written authorisation now rather than at the counter.
3. Design the stay so it's legal. Minimum 3 days, maximum 30 consecutive days per group, whole home or one room with a private bathroom, main building only, no guest use of an outdoor fireplace, and no more than 60 days a year with the whole place let while you're away.
4. Buy the liability policy. You'll need proof of at least $2,000,000 per claim before the province will register you.
5. Apply for the certificat d'occupation and pay the $200. Bring the occupancy declaration, the unit description, the services description, the parking table and the plans. Remember that you get 6 months to answer a request for missing documents.
6. Register with the CITQ once the city document is in hand. Budget $54 for a principal residence establishment and expect to supply photographs, your accommodation offering and proof of insurance.
7. Send the registration back to the city within 60 days. Miss this and the occupancy certificate you just paid for is null and void.
8. Put the number everywhere it belongs. In the listing and any advertising, on the certificate displayed at your main entrance or the building's, and filed with each platform you use.
9. Set the tax up before the first guest. Check whether your platform is collecting the 3.5% lodging tax and the GST/QST for you, and watch the $30,000 threshold that makes registration mandatory.
10. Diarize the renewal. The provincial registration runs 12 months and the renewal is due in the 60 days before it ends.

Who to Contact in Saint-Lambert about Short-Term Rental Regulations and Zoning?

Two of those steps are municipal and the rest are provincial, which is also how the phone numbers split.

Zoning, the occupancy certificate and enforcement

The Direction de l'urbanisme at the Ville de Saint-Lambert answers zone questions, issues the certificat d'occupation and applies the by-laws.

The urbanism by-law index carries the current codified PDFs of the zoning, permits and construction by-laws, and those codifications get updated more often than you'd expect, so pull a fresh copy rather than an old download.

Provincial registration

The Corporation de l'industrie touristique du Québec processes registrations for tourist homes, principal residences and most other classes.

Checking someone else's status

Quebec maintains a public register of registered establishments at repertoire.hebergement.tourisme.gouv.qc.ca, searchable by address. It works in both directions, of course. A neighbour can check your listing as easily as you can check a competitor's.

What Do Airbnb Hosts in Saint-Lambert on Reddit and Bigger Pockets Think about Local Regulations?

Anyone can look your address up in that register, and it shapes how hosts in this part of Quebec talk about compliance. What follows is my read of recurring themes in public discussion rather than a survey, since Reddit blocks the automated access a real one would need, so do weigh it accordingly.

• Investors talk about Montérégie, not Saint-Lambert. The commercial model people arrive looking for, a furnished unit let at nightly rates, is authorised in five zones here and registered in none of them. Discussion of South Shore short-term rentals drifts to Longueuil, to the Eastern Townships, or out of nightly rentals into 31-plus-day furnished stays that fall outside the Act entirely.
• The 3-day minimum draws more complaints than the 60-day cap. A suburb this close to a bridge sells weekends, and a rule that kills every one-night and two-night booking removes a large share of the demand before the cap ever binds.
• The paperwork order trips up newcomers repeatedly. People pay the CITQ first, discover the municipal conformity document is a precondition rather than a follow-up, and lose weeks. Saint-Lambert's own 60-day rule for returning the registration then catches the ones who relax too early.
• Condo boards are the quiet gatekeeper. In buildings, the declaration of co-ownership decides this before any government does, and syndicate refusals come up constantly in Quebec host discussion.

Take the registration counts seriously when you weigh all that. Zero registered tourist residences and zero registered gîtes in a city of this size, next door to a Longueuil that has 19, says the commercial version of this business hasn't found a way through the zoning here.

Frequently Asked Questions

Can you legally run an Airbnb in Saint-Lambert, Quebec in 2026?

Yes, in your own home. Saint-Lambert's zoning by-law authorises principal-residence tourist accommodation across the whole city, so long as each group stays at least 3 days and no more than 30 consecutive days. The accommodation has to be inside the main building, and the whole dwelling can be let without its usual residents present for no more than 60 days a calendar year. A whole unit run purely as a rental is a commercial use, permitted in only five zones, all of them outside residential streets.

What permits do you need for a short-term rental in Saint-Lambert?

Two, in this order. First a certificat d'occupation from the Ville de Saint-Lambert, priced at $200 in the 2026 fee schedule, which requires an occupancy declaration and proof that any lease or co-ownership declaration allows the use. Second, registration under Quebec's Tourist Accommodation Act, obtained through the CITQ for $54 for a principal residence establishment and valid 12 months. The city registration proof must go back to the city within 60 days, or the occupancy certificate is void.

What taxes apply to a Saint-Lambert Airbnb?

Three. Quebec's tax on lodging at 3.5% of the price of each overnight stay, GST at 5%, and QST at 9.975%. Where the booking runs through a registered digital accommodation platform, the platform handles collection, and a host registered for GST/QST charges and remits those two directly instead. Saint-Lambert levies no accommodation tax of its own. Federally, section 67.7 of the Income Tax Act denies expense deductions for days a rental was operating out of compliance.

What are the fines for an illegal short-term rental in Saint-Lambert?

The city's zoning by-law sets $500 to $1,000 for an individual and $1,000 to $2,000 for a company for renting an accommodation unit without first obtaining the certificate, rising to $1,000 to $2,000 and $1,750 to $4,000 on a repeat, with each day counted as a separate offence. Quebec adds $2,500 to $25,000 for an individual operating an unregistered establishment or advertising a false or expired registration number, and $5,000 to $50,000 for operating after a cancellation.

Can you rent a whole house or condo in Saint-Lambert as an Airbnb?

Only in the five zones where the zoning by-law authorises a résidence de tourisme: CA-1, MI-1, MI-2, MI-7 and MI-8. In every residential zone the answer is no, whatever the building type. The alternative for a whole unit is a stay of 32 days or more, which falls outside Quebec's Tourist Accommodation Act and outside the city's short-term rental conditions, landing instead under ordinary landlord and tenant rules.
