$1,132.00 (3.38%)
Lease renewed from July 1, 2027 to June 30, 2028 · reference cycle 2027
The TAL publishes the 2027 base rate in January 2027. Until then, the calculation suggests the latest published rate, the one for 2026 (3.1%).
| Base rate (3.1% of rent) | $33.95 |
|---|---|
| Municipal taxes 2027 vs 2026 | $2.10 |
| School taxes 2026-2027 vs 2025-2026 | -$0.40 |
| Insurance (Dec. 31, 2026 vs 2025) | $0.85 |
| Major expenditures 2026 (5%) | $0.00 |
| New services | $0.00 |
| Monthly adjustment | $36.50 |
| New rent (rounded to the dollar) | $1,132.00 |
Unit's share of the building's income: 15.64%
Tax or insurance increase: only the part above the base rate counts; a decrease is passed on in full. Unit's share = annual rent ÷ the building's annual income (major expenditures: share of rents, or 100% if they concern this unit only).
Estimate under the Regulation respecting the criteria for the fixing of rent (2026 version) — the TAL's calculation tool prevails. The tenant may refuse; the TAL then fixes the rent.
This tool gives an estimate, for information only: it isn't legal advice. If the tenant refuses, the Tribunal administratif du logement fixes the rent, and its calculation tool is the reference.
How the calculation works
The tool follows the Regulation respecting the criteria for the fixing of rent as in force since January 1, 2026, which covers notices of modification given since that date. It's the same calculation as in Plexago.
- Base: the current rent multiplied by the year's base rate (3.1% in 2026, the average of Quebec inflation over the last three years).
- Municipal taxes, school taxes and insurance, each on its own: an increase only counts for the part above the base rate; a decrease counts in full. The amount kept is multiplied by the unit's share, then divided by 12.
- Major expenditures (repairs or improvements) from the previous year, minus assistance and compensation: 5% of their cost, according to the unit's share of the rents, divided by 12. An expenditure for this unit alone counts at 100%.
- New services: their annual cost, according to the unit's share, divided by 12.
- The new rent is rounded to the nearest dollar ($0.50 and up rounds up).
The years compared. For a lease renewed between April 2 of a year A and the following April 1: municipal taxes for A and A−1, school taxes for (A−1)-A and (A−2)-(A−1), insurance in force on December 31 of A−1 and A−2, and major expenditures in year A−1. The tool works out A from the lease end date.
The unit's share: its annual rent divided by the building's annual income (the rents of every unit, times 12, plus other income).
