How rent increases are calculated in Québec in 2026

Rent increases in Québec are governed by precise rules that every landlord must master to act lawfully and avoid disputes. In 2026, the rent-setting method was substantially revised: the Tribunal administratif du logement (TAL), Québec’s rental housing tribunal, now uses a simplified formula whose main component is based on the consumer price index.

This article explains the new method, how to estimate a compliant increase and how to send a notice by the rules.

The new method for calculating rent increases in Québec in 2026

A new method applies to applications for the fixing of rent where the notice of lease modification was sent on or after January 1, 2026. The old method continues to apply to applications related to a notice given before that date.

Previously, the grid distinguished numerous categories of expenses, including energy, maintenance, services, management fees and net income. The new approach builds the calculation around a base percentage, to which adjustments for taxes, insurance and capital expenditures may be added. A special rule also applies to the portion of the rent corresponding to services related to the person of a tenant in certain seniors’ residences.

The reference rate for 2026

For rents whose period begins between April 2, 2026 and April 1, 2027, and when the notice was sent on or after January 1, 2026, the base percentage published by the TAL is 3.1% (in French).

This percentage is based on the average of the general CPI for Québec over the three previous years. This moving average aims to limit overly sharp variations from one year to the next.

What this rate means in practice

Applying only the base percentage, a monthly rent of $1,000 would yield an adjustment of $31 per month. For a rent of $1,500, the base adjustment would be $46.50 per month.

The 3.1% rate, however, is neither an automatic increase nor a universal cap. The landlord and the tenant may agree on an amount they consider satisfactory. In the event of disagreement, each rent-setting calculation remains specific to the building and unit concerned.

The components of the calculation in 2026

The TAL’s new grid takes the following elements into account to calculate a rent increase in Québec:

Component	Treatment in the calculation
Base percentage	Indexation of the rent according to the general CPI for Québec, calculated on a three-year average; 3.1% in 2026
Personal services in private seniors’ residences (RPA)	The portion of the rent corresponding to these services is adjusted according to an indicator specific to health care; 6.7% in 2026
Municipal and school taxes	Additional adjustment possible when their increase exceeds the base percentage
Insurance	Additional adjustment possible when its increase exceeds the percentage applicable to the rent
Capital expenditures	5% of the eligible expenditures for the reference period may be taken into account, after the adjustments set out in the regulation

The 5% rate applicable to capital expenditures corresponds to the annual portion used in the calculation, the equivalent of spreading the cost over 20 years. It is not a minimum spending threshold. Government assistance related to capital expenditures or to certain new services must also be taken into account.

To obtain an estimate close to the one the Tribunal would make, the owner must enter accurate data in the TAL’s 2026 calculation tool (in French) and keep the relevant invoices, tax bills, insurance policies and proofs of payment.

How to send a compliant increase notice

The increase notice must be in writing and sent within a deadline that varies according to the type of lease:

• lease of 12 months or more: between 3 and 6 months before the end of the lease;
• lease of less than 12 months: between 1 and 2 months before the end of the lease;
• lease with an indeterminate term: between 1 and 2 months before the proposed modification;
• lease of a room: between 10 and 20 days before the end of the fixed-term lease or before the proposed modification.

The notice must state the new rent, the amount of the increase or its percentage. It must also specify any other proposed modification, the new term of the lease if it changes, the tenant’s response deadline and the mandatory text prescribed by regulation. Finally, it must be dated and signed by the owner or their mandatary.

The TAL’s model is strongly recommended, but what matters most is that the notice sent meets all legal requirements. The owner should also keep proof of receipt, for example an acknowledgment of receipt, proof of registered mail or any other valid means.

It is not mandatory to attach all supporting documents to the notice. Giving the tenant access to the relevant data can, however, make an agreement easier and may be considered by the Tribunal when it rules on the reimbursement of costs for a potential application.

Entrust the management of notices and renewals to a property manager

What the tenant can do after receiving the notice

A tenant who receives a notice of lease modification has one month to inform the owner of their decision. Three options are available:

1. accept the modifications and renew the lease;
2. refuse the proposed modifications and renew the lease;
3. not renew the lease and leave the unit at the end of the lease.

If the tenant does not respond within one month of receipt, they are deemed to have accepted the renewal under the proposed conditions.

When the tenant refuses the increase while renewing their lease, the owner has one month after receiving the refusal to ask the TAL to fix the rent. If they do not do so within that deadline, the lease is renewed at the same rent and under the same conditions. Special rules apply in particular to cooperatives and to certain buildings built or converted five years ago or less.

Common mistakes in managing rent increases

Several mistakes can make a notice contestable or cause the owner to lose the ability to modify the lease for the year in question:

• sending the notice too early or too late;
• omitting the mandatory text, the response deadline, the date or the signature;
• keeping no proof of receipt;
• treating the 3.1% rate as a cap or as an automatic increase applicable to all units;
• calculating an adjustment for taxes, insurance or capital expenditures without reliable documents;
• forgetting to file the application for the fixing of rent within one month of the tenant’s refusal.

These mistakes can be avoided with a renewal calendar, an up-to-date financial file for each building and a systematic review of notices before they are sent.

Delegate rental management to avoid costly mistakes

Rent increases in Québec in 2026: what it changes for landlords

The 2026 reform simplifies the base calculation, but it still demands rigour. The date the notice is sent determines the applicable method, while adjustments related to taxes, insurance and capital expenditures must be based on data specific to the building.

An owner who masters this mechanism can propose compliant increases, defend their calculation before the TAL if necessary and maintain a more transparent landlord-tenant relationship. The official tool remains the best starting point, followed by a careful check of the deadlines and content of each notice.

FAQ

What is the rent increase rate in Québec in 2026?

The base percentage published by the TAL for 2026 is 3.1% when the new method applies. It concerns in particular rents whose period begins between April 2, 2026 and April 1, 2027 and notices sent on or after January 1, 2026. It is neither an automatic increase nor a universal cap.

Can a landlord raise the rent above the TAL’s reference rate?

Yes. The parties may agree on an increase they consider satisfactory. When the rent is fixed by the TAL, adjustments related to taxes, insurance and capital expenditures may be added to the base percentage according to the regulatory criteria and the data specific to the building.

What happens if a tenant refuses the rent increase?

The tenant must send their refusal within one month of receiving the notice. The owner then has one month to ask the TAL to fix the rent. Without an application within that deadline, the lease is renewed at the same rent and under the same conditions, subject to the special situations provided for by law.
