The Tribunal administratif du logement annually establishes the applicable percentages for the purpose of calculating the rent increases, in accordance with the Regulation respecting the criteria for the fixing of rent.

The percentages enable the amounts attributed to each component of the calculation to be determined on the basis of the actual expenses incurred for the building or dwelling in question.

To facilitate agreements on rent increases, the Tribunal provides an online calculation tool (in French only) to establish the rent increase, by taking into account the variation in municipal and school taxes, insurance, major improvements and all the building’s operating costs. A printable PDF version of the Calculation 2025 form is also available.

It is important to point out that each calculation is specific to the building or dwelling concerned. Moreover, the simplified calculation tools make no allowance for certain particular situations that could be the subject of a hearing before the Tribunal administratif du logement, such as a new service that results in additional management costs, or an expenditure that does not benefit all the occupants of the building.

The specific rules that apply to rental unit rent increases (e.g., time periods allowed for serving notices, particular circumstances for members of a cooperative or someone living in low-rental housing) are explained in the section Changing a condition of the lease.

The Tribunal’s website also provides models that can be used for notices of rent increase and replies to such notices.
