Under the Residential Tenancies Act, 2006 (RTA), Ontario landlords must adhere to annual rent increase guidelines set by the provincial government. However, when operating costs surge or major structural investments are made, landlords can apply to the Landlord and Tenant Board (LTB) for an Above-Guideline Increase (AGI) by filing Form L5: Application for a Rent Increase Above the Guideline.

At Lex Defensio, our legal team assists property owners, corporate landlords, and property managers in organizing financial evidence, completing complex L5 calculations, and securing AGI approvals from the LTB.

Statutory Grounds for Filing Form L5

The LTB will only grant an Above-Guideline Increase under three explicit statutory criteria defined in Section 126 of the RTA:

1. Extraordinary Increase in Municipal Taxes and Charges

Landlords can apply if municipal property taxes, education taxes, or municipal utility charges for the residential complex increase by an “extraordinary” amount.

  • Definition of Extraordinary: The percentage increase must exceed the annual rent increase guideline plus 50% of the guideline.
  • Cap Limit: Rent increases granted solely under municipal tax hikes are not capped at 3% and can match the full extraordinary tax burden across units.

2. Capital Expenditure Projects

Capital expenditures involve major work undertaken to repair, replace, or renovate structural elements or critical building systems. To qualify, work must fall under one of these categories:

  • Protecting, restoring, or maintaining the physical integrity of the property.
  • Enhancing accessibility for persons with disabilities.
  • Promoting energy or water conservation.
  • Maintaining or enhancing security services or facilities.

Restrictions: Routine maintenance, cosmetic upgrades, or work done on units that were vacant prior to lease signing do not qualify for capital expenditure AGIs. AGIs for capital expenditures are strictly capped at a maximum of 3% per year above the guideline for up to three consecutive years (maximum 9% total).

3. Security Services

Landlords may claim AGIs when introducing new security guard services or security facilities for the first time, or when expanding existing security services provided by third-party contractors.

Step-by-Step Form L5 Filing Workflow

  1. Issue Form N1 (Notice of Rent Increase): Prerequisite Step. Serve tenants with a Form N1 (Notice of Rent Increase) incorporating the proposed AGI rate.
    • Must provide a minimum of 90 days’ notice before the effective date.
    • Must check the box indicating that an AGI application has been (or will be) filed with the LTB.
  2. File Form L5 with the LTB: Strict Statutory Filing Window. Submit the L5 Application package to the Landlord and Tenant Board.
    • Filing Deadline: Form L5 must be filed at least 90 days before the first proposed rent increase date.
    • Filing Fee: $233 for up to 10 units (plus $1 per additional unit up to a maximum fee).
  3. Assemble & Upload Detailed Supporting Documentation: Evidence Submission. Upload mandatory financial and physical evidence to the LTB Portal:
    • Municipal tax assessments and tax bills for the current and prior years.
    • Proof of capital expenditures, including contractor contracts, invoices, proofs of payment, and work scope breakdowns.
    • Evidence establishing the necessity and completion of capital work.
  4. Serve Application Package & Open Evidence File: Tenant Inspection Period.
    • Once processed, serve a copy of the L5 Application and Notice of Hearing package to all affected tenants.
    • Landlords must make all supporting documentation available for tenant inspection prior to the hearing.
  5. Attend Case Management Hearing & Written/Oral Proceeding: LTB Proceeding.
    • Participate in an LTB Case Management Hearing (CMH) to explore mediated settlements with tenant representatives.
    • If unresolved, present expert testimony, contractor records, and accounting ledgers at the formal LTB AGI hearing.
  6. Collect Order-Approved Rent Adjustments: Implementation.
    • Upon receiving the LTB Order, issue formal recalculation notices to tenants.
    • Collect retroactively owed AGI amounts if tenants paid only the standard guideline rate while waiting for the LTB decision.

Frequently Asked Questions (FAQ)

Tenants are legally required to pay the standard annual guideline increase on the effective date of notice. They can choose whether to pay the additional AGI portion prior to the order. If the LTB approves the L5 application later, tenants will owe a retroactive lump-sum payment for the approved AGI amount accumulated since the effective date.

No. AGIs apply only to existing sitting tenants. When a unit becomes vacant, landlords can re-list the unit at market rent without needing LTB approval. Furthermore, capital expenditure costs incurred on a vacant unit cannot be used in an L5 application for existing tenants in other units unless the work benefited the entire complex (e.g., roof replacement or underground garage repairs).

Yes. Tenants or tenant associations frequently challenge L5 applications at the LTB. Common defences include claiming the capital work was “routine maintenance,” disputing whether work was completed properly, or alleging outstanding maintenance issues (Form T6 counter-claims) under Section 126(12) of the RTA.
