Calculate the justifiable rent increase for 2026
Your landlord is proposing an increase? Estimate in 30 seconds what the Tribunal administratif du logement would consider justifiable, based on the official percentages published in January.

The rent on your lease, before the proposed increase.
Used to split taxes and heating across dwellings.
Increase (or decrease, negative value) of municipal and school taxes combined. Visible on the tax bill or the landlord's statement.
Capital expenditures attributable to your dwelling (lasting renovations, not routine maintenance).
How the TAL calculates the adjustment in 2026
Since January 1, 2026, a new calculation method applies to notices of lease modification. The core of the calculation: a base percentage of 3.1% applied to the current rent. Where applicable, it adds an energy component when heating is included in the lease (2.9% for electricity, 13.7% for gas, 4.9% for oil, applied to the building's heating cost), the change in municipal and school taxes split across dwellings, and a 5% return on capital expenditures (major work).
This estimate is simplified: the tribunal's official calculation relies on the landlord's actual supporting documents (tax bills, invoices, contracts). If a rent-setting application is filed, the TAL's own tool and method prevail.

You have 1 month to respond: silence means acceptance
When you receive an increase notice, the law gives you one month to respond (art. 1945 C.c.Q.). Saying nothing counts as accepting. You can refuse the increase while keeping your home: the landlord then has one month after your refusal to ask the TAL to set the rent. Send your refusal in writing, with proof of receipt.

How much can rent increase in 2026 in Quebec?
There is no legal cap: the landlord proposes, the tenant accepts or refuses. If they disagree, the TAL sets the rent using its criteria. For 2026, the base percentage is 3.1% of the rent, plus taxes, energy (if heating is included) and major work. An increase well above the result of that calculation, without justification, can be refused.
Can I refuse a rent increase?
Yes, in most cases. Respond in writing within one month of receiving the notice, stating that you refuse the change but are keeping your home. The landlord then has one month to apply to the TAL: otherwise the lease renews on the current terms. Exception: some new buildings (5 years old or less) are exempt from rent setting.
Is this page's calculation the official one?
No: it's a simplified estimate based on the TAL's official percentages. The official calculation requires the building's real expenses, with supporting documents. Use our estimate to judge whether the proposed increase is reasonable, and the TAL's official tool for a complete calculation.
What if my landlord won't justify the increase?
Refuse the increase in writing within the one-month deadline and ask for the supporting documents. Without an agreement, it's up to the landlord to take the question to the TAL, where they must produce their documents. Keep proof of receipt of your refusal: that's what protects your rights.
