In Quebec, the rent increase notice must respect precise deadlines based on the lease term, be calculated according to criteria recognized by the Tribunal administratif du logement, and sent using the prescribed form. A notice sent outside the deadline or improperly drafted can cause you to lose the increase for an entire lease year.
Deadlines to respect depending on the type of lease
The deadline for sending a rent increase notice depends on the term of the current lease:
- Lease of 12 months or more: the notice must be sent between 3 and 6 months before the end of the lease.
- Lease of less than 12 months: the notice must be sent between 1 and 2 months before the end of the lease.
- Lease with no fixed term: the notice must be sent between 1 and 2 months before the proposed change date.
These windows are fixed. A notice sent a week too early or too late has no legal effect, even if the amount requested is perfectly justified. For a portfolio of several buildings with renewal dates that never line up, tracking these deadlines quickly becomes the real risk in the file.
How to calculate a fair and reasonable rent increase
The Tribunal administratif du logement provides landlords and tenants with a calculation tool to establish an increase considered fair and reasonable. The 2026 calculation tool takes into account, among other things:
- changes in municipal and school taxes,
- building insurance,
- major improvements carried out,
- the building's operating costs.
The adjustment is therefore not based on a discretionary decision, but on regulated criteria. A solid file documents each of these elements, supported by invoices and assessments, so it can withstand a challenge before the Tribunal.
The official form and what it must contain
The Tribunal provides a prescribed template, the "Notice of Rent Increase and Modification of Another Condition of the Lease." Using this form isn't a mere formality: it structures the mandatory information (current amount, proposed amount, effective date, other changes to the lease) that the tenant must find in order for the notice to be considered valid.
What happens if the tenant doesn't respond or refuses
The tenant has one month from receipt of the notice to respond. If they don't respond within that time, they're deemed to have accepted the change. If they refuse instead of simply ignoring the notice, the case can end up before the Tribunal, where proof of the calculation and compliance with deadlines becomes decisive.
Relevé 31 slips follow the same tight schedule
The rent increase notice isn't the only deadline to watch each year. The Tribunal reminded landlords that they had until February 28, 2025 to produce relevé 31 slips and send a copy to Revenu Québec as well as to tenants or subtenants. Two separate legal obligations, two schedules to respect, for every unit in the portfolio.
For a portfolio of several buildings, every file matters
A landlord managing a single duplex can track these deadlines in a notebook. A landlord with a portfolio of several buildings, with dozens of leases renewing on different dates, can't afford a single missed or miscalculated notice: that means a full year of rental income stuck at the previous rate.
This is exactly what Gestion Morin takes care of: increase notices, relevé 31 slips, leases and, when needed, cases before the Tribunal administratif du logement are managed according to the deadlines and criteria in effect, building by building. Major improvements that justify an increase are also carried out in-house thanks to Gestion Morin's RBQ licence, keeping every file consistent from calculation through to the work itself. For a landlord who wants to take back control of their portfolio without taking back the calls and deadlines, a quote request allows you to review the full picture of all the buildings involved.
A well-managed portfolio isn't measured only by the rent collected, but by the strength of every legal file behind every unit. This behind-the-scenes work, quiet but rigorous, is what protects long-term revenue. Request a quote to assess where your notices and relevé 31 slips currently stand.
Frequently asked questions
By what date can a landlord send a rent increase notice?
It depends on the lease term: between 3 and 6 months before the end of a lease of 12 months or more, between 1 and 2 months before the end of a lease of less than 12 months, and between 1 and 2 months before the proposed change date for a lease with no fixed term. A notice sent outside this window has no legal effect.
What is the legal rate for rent increases in Quebec?
There's no single rate imposed by law. Instead, the Tribunal administratif du logement provides a calculation tool that takes into account taxes, insurance, major improvements, and the building's operating costs to establish an increase considered fair and reasonable.
How do you notify a tenant of a rent increase?
The notice must be sent in writing, ideally using the Tribunal's prescribed form, indicating the current amount, the proposed amount, and the effective date. The tenant then has one month to respond, otherwise they're deemed to have accepted.
When will I receive my rent increase notice for 2026?
The timing depends on the end date of your current lease, following the same deadlines as any other year: between 3 and 6 months before expiry for an annual lease. The Tribunal's 2026 calculation tool is specifically designed to establish the applicable amount for that period.
What if the tenant refuses the proposed rent increase?
If the tenant refuses instead of simply not responding, the case can be brought before the Tribunal administratif du logement, which will decide based on recognized calculation criteria. The strength of the file, including proof of costs and compliance with deadlines, then becomes decisive.
