How do i know if a rent increase is too high?
Short answer
In Quebec, there is no single cap: the Tribunal administratif du logement (TAL, Quebec's rental board) calculates the increase from the actual changes in the building's expenses, and each year it publishes percentages as well as an online calculation tool.
In detail
Rent is not governed by a mandatory maximum percentage. When it has to decide, the Tribunal administratif du logement (TAL, Quebec's rental board) applies a regulation that takes into account, among other things, municipal and school taxes, insurance, energy, maintenance, major work and indexation.
The TAL makes a free calculation tool available to tenants and landlords to estimate a fair and reasonable increase. It also publishes the applicable percentages each year.
Note: a new calculation method applies to applications to fix rent where the notice of modification of the lease was sent on or after January 1, 2026. For notices sent before that date, the former method continues to apply.
What to document
The current rent and the rent being asked for, the date of the notice (before or after January 1, 2026), and any document the landlord provides about their expenses. Also note any services removed or added during the year.
Put your facts in writing, free. Writing your version down early, keeping your documents dated and preparing your questions for a lawyer: the tool is there to document, never to advise.

What this page is not
This is general legal information about the law of Quebec and Canada, dated and sourced. It is not legal advice, not a strategy, and not a prediction about the outcome of a case. In Quebec, only lawyers and notaries may give legal advice (Act respecting the Barreau du Québec, ss. 128 and 133). Laws and amounts change: the official source always prevails over us.
