Montreal did not ban short-term rentals outright. It banned them for ten months of the year in the one category most people list in: the City of Montréal allows short-term rental of a principal residence only from June 10 to September 10, and only with a host permit, while rentals outside a principal residence stay legal year-round in a short list of commercial zones with a certificate of occupancy. The $19 million CAD figure that circulated before the 2026 Formula 1 Canadian Grand Prix came from a study commissioned by Airbnb in March 2026, and it covered two events, not one weekend. It was an estimate made before the race, not a measured outcome, and as of September 22, 2026 no realized loss figure has been published by the city or by Québec.
That distinction matters more than the headline. I have operated short-term rentals since 2016 and trained more than 10,000 operators, and the pattern I keep seeing is operators losing regulatory fights because they argue with a vendor-funded projection instead of the bylaw text. The bylaw text is where your money is.
What the $19 Million Estimate Can and Cannot Prove
The number came from Raymond Chabot Grant Thornton in an analysis commissioned by Airbnb and published in March 2026. The study estimated a deficit of more than 26,000 accommodation nights across two 2026 events — the Formula 1 Canadian Grand Prix on May 22-24 and the UCI Road World Championships in September — and roughly $19 million CAD in forgone tourism spending for Montréal across both. The $19 million was never a single-weekend number. Airbnb paid for the work. That does not make the arithmetic wrong, but it does mean the figure is a party's estimate, dated March 2026, and should be quoted that way.
What I have not been able to verify from any primary source is what actually happened. Neither Ville de Montréal nor the Government of Québec has published post-event accommodation or visitor-spending data for the May 22-24, 2026 race weekend. So the claim I can defend is narrower: a consultancy hired by the largest platform projected a 26,000-night gap and $19 million in lost activity before the event; as of September 22, 2026 the realized figure is still unpublished. If an operator repeats it as a measured loss in a council meeting, the first person who checks the source will end your credibility for the rest of the hearing.
Same discipline applies to the other numbers that traveled with this story. Hotel rate spikes quoted as percentages, "70% of hotel blocks," and combined event totals above $30 million all trace back to press coverage or platform communications, not to a government release. I am dropping them rather than laundering them through another article.
Montreal's Rules, Type by Type
The useful work is reading what the city actually permits. Montréal publishes this by rental type, and the differences decide whether an event weekend is legal inventory for you or a fine waiting to happen.
One caveat on currency: Montreal Gazette reporting in April 2026 said the city intended to revisit the seasonal restriction, but not in time for the Grand Prix. As of September 22, 2026 montreal.ca still publishes the June 10 to September 10 window, so the table below reflects the rule in force today. Re-read the city page before you price a 2027 event weekend.
Rental type | When it is allowed | What you need |
|---|
Principal residence (whole unit or a room) | June 10 to September 10 only, in most boroughs | Host permit; prohibited entirely in Lachine, Saint-Laurent, Saint-Léonard |
Tourist accommodation that is not your principal residence | Year-round, stays of 31 days or less | Certificate of occupancy; only in designated commercial areas |
Bed and breakfast | Depends on borough, year-round where allowed | Borough check; certificate of occupancy where required |
Home exchange (HomeExchange and similar) | Year-round | No permit |
Lease longer than 31 days | Year-round | Outside the tourist accommodation regime |
Read the first row against a race calendar and the whole story gets simpler. A Grand Prix weekend in late May sits outside June 10 to September 10. So does the UCI Road World Championships window in Montréal this September. A principal-residence host in Le Plateau cannot legally take those bookings no matter what the demand curve says. A permitted commercial tourist home on an authorized stretch of Rue Notre-Dame Ouest can take them all year. Montréal did not remove event-weekend supply; it moved event-weekend supply into a permit class that very few hosts hold, in a small number of blocks, and in some boroughs it spaced those units at least 150 metres apart.
That is the sentence I would carry into a council hearing. A seasonal window does not reduce demand. It reassigns who is allowed to serve it.
The Cost and Penalty Stack on a Legal Montreal Listing
Québec's registration regime sits on top of the municipal rules, and the published amounts are small next to the published fines. The numbers below come from the province's own registration and penalties pages and Montréal's permit page.
Line item | Published amount |
|---|
Québec registration, principal residence establishment (2026) | $54 |
Québec registration, general tourist accommodation establishment (2026) | $156 |
Québec registration, youth tourist accommodation establishment (2026) | $131 |
Civil liability insurance required per event | $2,000,000 |
Montréal notice-of-compliance review fee (example borough) | $63 |
Fine, operating an unregistered establishment (individual) | $2,500 to $25,000 |
Fine, operating an unregistered establishment (other cases) | $5,000 to $50,000 |
Fine, no registration number in advertising (individual) | $1,000 to $10,000 |
Fine, failing to carry the required liability insurance (individual) | $1,000 to $10,000 |
Do the arithmetic on the bottom half of that table. A principal-residence registration costs $54 a year. The minimum fine for operating without it is $2,500, which is about 46 times the fee, and the maximum for an individual is $25,000, about 463 times the fee. A single missing registration number in a listing headline can cost more than a season of legal bookings nets on one unit. Compliance in Québec is not expensive; non-compliance is.
There is a second lesson buried in the penalty schedule. Québec also fines platform operators for publishing non-compliant offers, which is why enforcement in this province does not depend on an inspector knocking. The listing is the evidence, and the platform has its own reason to remove it.
Why Hotels Cannot Absorb a Race Weekend
Hotel economics are built on year-round occupancy. A hotel adds rooms when the trailing twelve months justify the debt, not when one weekend in May spikes. So when a fixed room count meets a three-day demand surge, the only available lever is price, and price rations demand by removing the visitors with the least flexible budget.
Those visitors do not book at a higher rate. They stay home, or they pick a different race. The city loses their restaurant tabs, their transit fares, their retail spend, and their circuit tickets, not only their room nights. That is the mechanism the Airbnb-funded study was trying to price, and the mechanism is sound even if the specific dollar figure is unverified.
Short-term rental supply behaves differently because it is elastic in both directions. A resident lists in May and stops in October. A permitted operator adds a second unit in eight weeks, not eight quarters. Cities that want event capacity without permanent hotel overbuild get it from that elasticity. Cities that close the elastic layer during peak windows have chosen a smaller ceiling, which is a legitimate choice as long as the council says so out loud.
The Housing Argument, Tested Against the Bylaw
The stated purpose of Montréal's by-law is housing supply and fraud prevention, and the city says so plainly on its own page. I take the housing crisis seriously. My disagreement is about mechanism, and the bylaw itself gives the argument away.
If the concern is homes removed from the long-term market, the binding rule should be the one that governs non-principal-residence units, because those are the ones that never house a tenant. Montréal allows exactly that use year-round in designated commercial zones. What it restricted for ten months is the category where somebody already lives in the unit for the other ten months. A resident renting the place they live in from June to September is not withholding a lease. That unit was never in the long-term pool.
Where I will concede ground: concentration matters. Blocks where a majority of units run as unstaffed nightly rentals feel different to live on, and spacing rules and permit caps are a reasonable response to that. What does not follow is a seasonal prohibition on owner-occupied hosting, which reduces resident income without adding a single lease.
There is also a maintenance effect that gets left out. A nightly listing is graded in public every week. Deferred maintenance shows up in reviews within a month, and reviews control price. A long-term lease can hide three years of deferred maintenance until the roof fails and the accumulated cash flow goes back into the building. Both models can be run well or badly, but only one publishes its condition record.
Event-Window Playbook: Steps to Take Before Your City Votes
Montréal is now the reference case other councils will cite, so assume your market gets a version of this proposal. Here is the sequence I would run, in order, and it starts long before public comment opens.
Pull the actual ordinance draft and the zoning map, and write down which of your units survive under each rental class. Most operators discover at this step that one unit is fine and another is not.
Read the state or provincial registration statute on top of it. In Québec, the province sets registration and fines while the city sets the season and zones; if you only track one level, you will comply with the wrong one.
Assemble your own numbers for the record: nights booked, guest origin by city, average party size, local tax remitted, and cleaner and maintenance spend paid to local vendors. Your remittance receipts are the strongest document in the room because the city issued them.
Ask the council in writing to commission an independent economic analysis before the vote, and offer your anonymized data as an input. A study a platform pays for gets discounted; a study the city commissions does not.
Join or start a host association and send two or three people to public comment with the same numbers and different units. One operator reads as self-interest, six read as an industry.
Requalify each unit for a second use before the vote, not after. A unit that underwrites at 31-plus-day mid-term rates survives a nightly-rental ban; one that only works at event pricing does not.
Re-run your underwriting with the restricted season applied and decide, in advance, which units you keep, refinance, or sell. Deciding this under a 60-day compliance clock is how operators sell into a soft market.
If you want another operator to check that math with you before your own council vote, book a complimentary one-on-one diagnostic call. It costs nothing; if you want the written follow-on, the $997 action plan is the paid step, and most people do not need it to fix a unit-level underwriting question.
What Montreal Actually Teaches Operators
Rules change. They changed for restaurants, for taxis, for rideshare, and they will keep changing for nightly rentals. Planning a portfolio around a stable regulatory environment is planning around something that has never existed in any asset class I have operated in.
Defined rules are also what makes lending possible. When a city publishes permit classes, zones, and fees, an underwriter can price the asset. When a market is undefined, capital stays out and the only buyers are cash buyers. The Québec and Montréal framework is restrictive, and it is legible: registration classes, published fees, a $2,000,000 insurance floor, named zones, a named season. An operator can underwrite that. What no one can underwrite is a market where the rules arrive by press conference.
So the durable lesson from the 2026 Grand Prix is not the $19 million estimate. It is that the operators who kept revenue through that weekend were the ones holding a certificate of occupancy in an authorized commercial zone, plus the ones whose units also underwrite as 31-day-plus stays. They did the reading before the vote. Everyone else got a seasonal calendar and a press cycle.
Frequently Asked Questions
Is short-term renting legal in Montreal right now?
Yes, in defined forms. Renting your principal residence for short stays is allowed only from June 10 to September 10 in most boroughs, with a host permit, and is prohibited in Lachine, Saint-Laurent and Saint-Léonard. Renting a unit that is not your principal residence for stays of 31 days or less is allowed year-round, but only in designated commercial areas and only with a certificate of occupancy.
Did Montreal really lose $19 million because of the ban during the Grand Prix?
No. That figure is a pre-event estimate from a March 2026 Raymond Chabot Grant Thornton analysis commissioned by Airbnb, and it covered two events combined — the May 22-24 Grand Prix and the September UCI Road World Championships — alongside an estimated 26,000-night accommodation deficit. No city or provincial release has published a realized loss for the May 22-24, 2026 race weekend. Quote it as a dated estimate by an interested party, never as a measured result.
What does it cost to register a short-term rental in Québec?
The province's published 2026 registration fees are $54 for a principal-residence establishment, $156 for a general tourist accommodation establishment and $131 for a youth establishment. You also need civil liability insurance of at least $2,000,000 per event and municipal confirmation that your project complies with local zoning. Montréal boroughs charge their own review fees, for example $63 to review a notice of compliance.
What happens if I list without registering?
Québec's penalty schedule sets fines of $2,500 to $25,000 for an individual operating an unregistered establishment, and $5,000 to $50,000 in other cases. Omitting the registration number from advertising carries $1,000 to $10,000 for an individual, and so does failing to keep the required liability insurance in force. Platforms face their own penalties for publishing non-compliant offers, which is why listings get pulled without an inspection.
Do short-term rentals cause housing shortages?
Montréal's own explanation ties the by-law to housing supply and fraud prevention, so the concern is on the record. The part that does not follow is restricting owner-occupied hosting for ten months, since a unit the host lives in was never in the long-term rental pool. The stronger targets are concentration and non-resident units, which is why spacing rules and zone limits are more defensible than a seasonal prohibition.
How should I plan for 2027 event weekends in a restricted city?
Start from the permit class, not the demand forecast. Confirm whether the event dates fall inside your city's authorized season, and if they do not, decide whether a year-round commercial permit is obtainable for a unit you own or control. Then underwrite the unit at 31-day-plus rates so a single restricted weekend is not the difference between holding and selling.
