TAL method
How the TAL calculates the maximum increase
The Tribunal administratif du logement applies a multi-component formula rather than a single percentage. Each component reflects the actual variation in a specific cost category for the owner.
1. Base adjustment (operating costs)
Percentage indexed yearly by the TAL to cover general operating-cost evolution (routine maintenance, services, etc.). 2026 index: 1.8% of current rent.
2. Heating-energy index
When heating is included in rent, an additional index applies based on energy type: electric (3.0%), natural gas (4.0%), oil (5.0%).
3. Tax and insurance changes
Annual changes in municipal taxes, school taxes, and insurance premiums pass through fully (split proportionally across units). For example: if your municipal tax goes up $240/year for a 4-unit building, that's $60/unit/year, or $5/month.
4. Major works (capital)
For significant renovations, the cost is amortized over the asset's useful life (typically 25 years for roofs, 15-20 years for windows) with a 3.53% return. Keep your invoices — the TAL may demand them in case of dispute.
5. Total and rounding
The sum of components gives the maximum monthly increase. The TAL's official calculation includes some additional nuances (high-rent adjustment, etc.) — for a contestable decision, always validate on the official calculator.

Frequently asked questions
Practical answers for tenants and owners across Greater Montreal.
- Am I required to use the TAL grid to set my rent increase?
- You can propose any increase to your tenant. But if the tenant refuses and a case goes before the TAL, the tribunal applies the grid to decide. So in practice, the grid is the upper bound of what gets accepted in case of disagreement. An increase beyond the grid without documented justification risks rejection.
- Is this calculation exactly the same as the TAL's?
- It's a very close estimate, but the TAL has its own official grid that may include occasional adjustments. For an official estimate or in case of dispute, use the official tool at tal.gouv.qc.ca. Our calculator is a planning aid — it helps you avoid surprises.
- Which indices did you use for the calculation?
- The TAL 2026 indices: base adjustment (operating costs) 1.8%, electric heating 3.0%, gas 4.0%, oil 5.0%, capital return rate 3.53%. These indices are updated each year when the TAL publishes its new grid (typically in January).
- When must I send the rent-increase notice to the tenant?
- For a 12-month lease (the standard), the notice must be sent between 3 and 6 months before the end of the lease. Example: for a lease ending June 30, send the notice between January 1 and March 31. Outside that window, the tenant isn't required to respond and the lease auto-renews on current terms.
- Can the tenant refuse my increase?
- Yes. The tenant has one month after receiving the notice to refuse the increase. If they refuse, you have a further month to file with the TAL — otherwise the lease renews on current terms. If you file with the TAL, the tribunal sets the increase per the grid.
- What counts as 'major works' in the calculation?
- Significant renovations that durably extend or improve the building: roof, windows, brickwork, full kitchen or bathroom, electrical rewiring, major plumbing, etc. NOT routine maintenance (yearly painting, small repairs), which is already covered by the base adjustment. Keep all invoices — the TAL may request them in case of dispute.
- What if I want renewals handled every year without my involvement?
- That's exactly what our optional property management service handles: yearly TAL calculation, drafting and sending the notice within legal deadlines, dispute handling, support from an OACIQ real-estate broker if a TAL filing happens. Request a free evaluation if interested.
