Units first occupied after November 15, 2018 are exempt from the guideline.

Understanding This Calculator
Understand how rent-increase guidelines cap annual increases in rent-controlled jurisdictions, and how to check whether a proposed increase is legal.
How the math works
The arithmetic is simple: New rent = Current rent × (1 + increase %) and Dollar increase = Current rent × increase %. The legal question is whether the requested percentage exceeds your jurisdiction's guideline.
In rent-controlled provinces such as Ontario and BC, rent can typically rise once per 12-month period by no more than the annual guideline (Ontario's guideline was 2.5% for 2023, 2024, and 2025), with proper written notice — 90 days in Ontario using Form N1. Some units are exempt: in Ontario, units first occupied after November 15, 2018 have no guideline cap. Alberta and most US states have no percentage cap at all, only notice requirements.
Worked example
Using the defaults: current rent of $2,000 and a requested increase of 2.5% in Ontario.
- Dollar increase = 2,000 × 2.5% = $50
- New rent = 2,000 + 50 = $2,050 per month
- Guideline check: 2.5% requested vs 2.5% guideline → within the guideline
If the landlord had asked for 4% instead, the increase would be $80 and the calculator would flag it as above the guideline — permitted only with a Landlord and Tenant Board order for an above-guideline increase (AGI), or if the unit is exempt.
How to read the result
A result of within guideline means the percentage is allowed — but the increase must still follow procedure: proper written notice, the required notice period, and at least 12 months since the last increase or tenancy start. A result of above guideline is not automatically illegal; it may be valid if the unit is exempt or an AGI order exists.
Tenants who receive an above-guideline notice without an order can dispute it through their provincial tribunal (the LTB in Ontario). Always confirm against the official government guideline page for the year in question — this tool is an educational check, not legal advice.
