Montreal Rent Increases 2027 What Landlords Need to Know Before January
January is not the time to start thinking about rent increases. For many Montreal landlords, it is the time to act.
With Quebec’s revised rent calculation method now in effect, the 2027 renewal season will reward owners who prepare early. The key is not simply choosing a percentage. It is knowing which costs may support an adjustment, keeping the right documents, and sending notices within the required window.
For Montreal property owners, preparation should start well before the Tribunal administratif du logement, or TAL, publishes the 2027 reference percentage.

Quebec’s rent calculation method has changed
Quebec introduced a revised residential rent adjustment method on January 1, 2026. The goal is to make the calculation process easier to understand and more predictable for both landlords and tenants.
Under the revised framework, several items matter.
The base percentage
The base percentage is calculated using the average annual change in Quebec’s Consumer Price Index over the previous three years. For 2026, the TAL published a base percentage of 3.1%.
The percentage for 2027 rent adjustments is expected to be published in January 2027.
Municipal and school taxes
Eligible tax increases may support an additional adjustment when the percentage increase exceeds the base percentage. This makes tax bills especially important documents for owners to keep organized.
Insurance premiums
Insurance increases may also matter when the increase exceeds the base percentage. In a market where building insurance costs can change sharply, owners should keep both current and prior policy documents.
Major capital expenditures
Eligible major improvements are treated differently from ordinary operating costs. Under the revised method, eligible capital expenditures are subject to a fixed annual adjustment rate of 5%, with the resulting amount calculated according to the applicable rules.
That can include certain improvements to the building, but it does not mean every repair automatically qualifies. Replacing a broken item with a similar one may be treated differently from a major improvement that adds value or extends the useful life of the property.
The base percentage is not a universal cap
One common mistake is treating the TAL’s published percentage as a hard cap for every unit. That is not how the system works.
The base percentage is a reference point. The proper increase may be higher or lower depending on the building, the lease, the expenses, and the supporting documents.
For Montreal Rent Increases 2027, landlords should avoid copying a single percentage across every unit without reviewing the file behind it. Two apartments in the same building may have different rent histories, lease terms, included services, or prior adjustments.
A careful review should include:
The current rent and lease term
The previous rent increase history
Whether heating, parking, appliances, or other services are included
The building’s municipal and school tax changes
Insurance renewal documents
Eligible capital expenditure records
Any changes to services or conditions
This review helps reduce disputes. It also helps landlords explain the proposed increase clearly if a tenant asks how the amount was calculated.
Documents should be ready before notices go out
A rent increase notice is only one part of the process. The supporting file matters just as much.
Before January, landlords should gather documents for each property and keep them in a format that is easy to review. If a tenant refuses the increase and the file goes before the TAL, missing records can create problems.
At minimum, organize:
Document | Why it matters |
Current leases | Confirms rent, term, included services, and renewal dates |
Prior rent notices | Shows the unit’s rent adjustment history |
Municipal tax bills | Supports eligible tax-related adjustments |
School tax bills | Supports eligible school tax changes |
Insurance invoices and policies | Confirms premium changes from one year to the next |
Contractor invoices | Supports eligible work and project costs |
Proof of payment | Shows expenses were actually paid |
Work descriptions | Helps separate repairs from major improvements |
For capital work, keep more than the invoice. Retain contracts, photos, permits when applicable, completion dates, and a clear description of the work. If the project benefits several units, keep a record of how costs were allocated.
Notice deadlines can decide the outcome
Even a well-supported increase can run into trouble if the notice is late or incomplete.
In Quebec, notice periods depend on the lease type and length. For many fixed leases of 12 months or more, including the common July 1 lease cycle, the notice generally must be sent three to six months before the lease ends. For a lease ending June 30, that makes January 1 the start of the six-month window.
Shorter leases and indeterminate leases can have different notice periods. Landlords should confirm the applicable deadline before sending anything.
The notice should clearly state:
The proposed new rent
The date the new rent would take effect
Any other proposed lease changes
The tenant’s response options
The required response deadline, where applicable
Delivery also matters. Keep proof that the tenant received the notice. Depending on the situation, that may include registered mail, hand delivery with acknowledgment, or another reliable method allowed under Quebec rules.
Communication can prevent avoidable disputes
A rent increase is easier to discuss when the explanation is specific.
Instead of sending a bare notice with no context, landlords can prepare a short summary showing the main reasons for the adjustment. This does not need to be complicated. It should be factual and tied to the property.
For example, the summary might mention that municipal taxes increased, insurance premiums rose, or eligible work was completed during the relevant period. Avoid vague statements such as “costs went up.” Tenants are more likely to understand a proposal when they can see what changed.
Clear communication does not guarantee agreement. It can reduce confusion, shorten back-and-forth, and show that the landlord used a consistent process.
What landlords should do before January
The best preparation is simple and early.
Before the 2027 percentage is published, landlords should:
Review every lease renewal date.
Create a file for each property or unit.
Collect tax, insurance, and capital expenditure documents.
Separate routine repairs from possible eligible improvements.
Check notice deadlines for each lease.
Prepare draft notices before the window opens.
Confirm calculations once the TAL publishes the 2027 percentage.
The landlords who wait until January may still be able to act, but they will have less time to verify numbers, correct missing documents, and prepare clear notices.
The better approach is to treat rent increases as an annual record keeping process, not a last-minute decision. When the 2027 renewal season arrives, the strongest position will belong to owners who already know their numbers and can support them.
