Landlord and Tenant Board Rent Increase — What Happens at the LTB

When Rent Increases Land at the LTB

Most lawful rent increases never see the inside of a hearing room. You serve Form N1 or N2, the tenant pays the new amount, and the process is done. For rent-increase issues, the LTB commonly gets involved when a tenant challenges your increase or you apply for permission to go above the annual guideline.

Both paths follow a structured administrative process. Knowing what happens at each stage — and what evidence the Board expects — is the difference between walking out with your increase confirmed or walking out with a refund order against you.

Tenant Challenge: The T1 Application

When a tenant believes your rent increase is unlawful — wrong form, short notice, bad math, no 12-month gap — they file Form T1 (Tenant Application for a Rebate of Money the Landlord Owes) with the LTB. The filing deadline is 12 months from the date the allegedly unlawful amount was first charged or collected.

After filing, the LTB schedules a hearing. The Notice of Hearing gives the date, time, and format; hearings can be virtual (by Zoom or phone), written, or in person. The landlord is the respondent and carries the practical burden of proving the increase was properly executed.

What the Board examines at a T1 hearing:

• Whether you used the correct prescribed form (N1 for rent-controlled units, N2 for exempt units)
• Whether at least 90 days of notice elapsed before the effective date, accounting for deemed-service timelines
• Whether the 12-month frequency interval under RTA s. 119 was satisfied
• Whether the percentage matches the published guideline for the year of the effective date
• Whether service was completed through a legally permitted method

If the Board finds a procedural defect, the increase is void from the start. The order typically requires you to refund the overpayment, and the lawful rent reverts to the pre-increase amount. Under Bill 60 amendments effective July 1, 2026, you have only 15 days (down from 30) to request a review of an LTB order you disagree with.

Above-Guideline Increase: The L5 Application

If you need to raise rent beyond the annual guideline — to recover extraordinary property tax increases, eligible capital expenditures, or new or increased security service costs — you file Form L5 (Application for an Increase Above the Guideline) with the LTB. This is the landlord-initiated path, and you carry the full evidentiary burden from the start.

The L5 must be filed at least 90 days before the proposed effective date. You also serve Form N1 on affected tenants, noting both the baseline guideline increase and the pending AGI request. Tenants pay only the guideline portion until the Board rules.

The hearing sequence for an L5:

1. The LTB schedules a hearing and notifies all affected tenants
2. You present documentation proving your claim — contractor invoices, tax assessments, security contracts, and proof that expenditures meet the statutory thresholds in O. Reg. 516/06
3. Tenants may dispute the claimed amounts, the useful life calculations, or whether the work qualifies as eligible capital expenditure (routine maintenance and cosmetic upgrades do not qualify)
4. The Board issues an order — if approved, tenants owe the difference retroactively; if dismissed, only the guideline increase stands

Capital expenditure AGIs are capped at 3% above the guideline per year, to a maximum of 9% over three years. Security service AGIs carry the same 3% annual cap. Extraordinary municipal tax increases have no percentage cap but must exceed the guideline plus half the guideline (2.85% for 2027 increases) to qualify.

Under Bill 60 amendments, once the Board directs you to serve an AGI order on tenants, you now have only 7 days to do so (previously 14), and the Certificate of Service must reach the LTB within 5 days of service.

What Evidence to Bring

For a T1 defence (responding to a tenant challenge):

• The served Form N1 or N2 — the exact copy, not a blank
• Your Certificate of Service (Form P1) with the date, method, and address
• The lease agreement showing the tenancy start date and current lawful rent
• Records of every prior rent increase (dates and amounts)
• Mail receipts, email consent forms, or other delivery proof
• Your rent calculation showing the correct guideline applied to the correct base

For an L5 application:

• Contractor invoices and work orders with itemised costs
• Municipal property tax assessments (current and prior year)
• Security service contracts with pricing
• Building permits for capital work
• Proof that the useful life of each expenditure meets O. Reg. 516/06 Schedule 1 thresholds (e.g., roof = 20 years, appliance = 15 years, boiler = 20 years)

Preparing for the Process

The Board decides the case based on the evidence and submissions presented. A Certificate of Service and delivery records help substantiate how you served the notice. Support a capital expenditure claim with invoices, work orders, permits, and other records showing that the work meets the statutory criteria.
