Above Guideline Increase Ontario: The L5 Application Process

When the Guideline Isn't Enough

The annual rent increase guideline (2.1% for 2026, 1.9% for 2027) covers normal inflation. But when a landlord faces costs that meet the statutory criteria — such as eligible capital work, extraordinary municipal tax increases, or qualifying security costs — the guideline alone may not cover the expense. The Above-Guideline Increase (AGI) is the formal mechanism for applying for approval to recover eligible costs through rent.

AGIs apply only to rent-controlled units. Exempt units (first occupied after November 15, 2018) have no guideline cap in the first place, so the AGI process doesn't apply to them.

The Three Qualifying Grounds

Under RTA Section 126 and O. Reg. 516/06, a landlord can apply for an AGI based on:

1. Extraordinary municipal taxes and charges. The property tax increase must exceed the guideline plus 50% of the guideline. For 2026, the threshold is 2.1% + 1.05% = 3.15%. For 2027, it's 1.9% + 0.95% = 2.85%. Any tax increase above that threshold qualifies as extraordinary, and there's no statutory cap on the pass-through — the full extraordinary portion is applied in year one.

2. Eligible capital expenditures. Major work that affects the building's physical integrity, security, energy or water conservation, or accessibility. Routine maintenance and cosmetic upgrades don't qualify. The work must meet useful-life thresholds in O. Reg. 516/06 Schedule 1 (roof: 20 years, boiler: 20 years, appliances: 15 years). Items with a listed useful life under 10 years are deemed to be 10 years for calculation purposes. The AGI for capital expenditures is capped at 3% per year above the guideline, up to a maximum of 9% over three years.

3. Security service operating costs. First-time provision of security services, or increased costs for existing security provided by a third-party contractor. Capped at 3% per year above the guideline.

The L5 Application Process

Step 1: File Form L5. The application must be filed with the LTB at least 90 days before the requested effective date of the increase. Include all supporting documentation: invoices, contracts, tax assessments, building permits.

Step 2: Serve Form N1 on tenants. The N1 should indicate both the baseline guideline rate and the pending requested AGI percentage. The tenant isn't obligated to pay the AGI portion until the LTB rules on it.

Step 3: Interim payments. While the application is pending, tenants pay only the baseline guideline increase. The AGI portion is held in abeyance until the hearing.

Step 4: LTB hearing and order. The LTB adjudicator reviews the evidence, determines whether the costs meet the statutory criteria, and calculates the approved percentage. If approved, the order specifies the percentage increase and the effective date.

Step 5: Retroactive payment. Tenants must pay the approved AGI amount retroactively from the effective date. If the application is dismissed, no additional amounts are owed.

The Bill 60 Service Change

Effective July 1, 2026, under Bill 60 (Fighting Delays, Building Faster Act), the window for serving an LTB above-guideline order on tenants was shortened from 14 days to 7 days, and the Certificate of Service must be submitted to the LTB within 5 days of service. These are tighter deadlines than the previous regime, so track the service date and Certificate of Service filing date separately.

The Alternative: Form N10 Agreements

If the AGI route seems heavy for a specific improvement, RTA Section 121 offers a lighter alternative. A landlord and tenant can voluntarily agree to an increase above the guideline using Form N10 in exchange for specified capital improvements or new services.

The cap on an N10 agreement is guideline plus 3%. The tenant has a statutory right to cancel within 14 days of signing. N10 agreements are bilateral — they require the tenant's informed consent, not just notification.

Is an AGI Worth the Effort?

The L5 process involves filing fees, document preparation, a hearing before the LTB, and potentially months of waiting. For a small landlord with one or two units, the administrative burden can outweigh the financial benefit unless the extraordinary cost is substantial.

Whether an L5 is worthwhile depends on whether the expense meets a statutory ground and what amount the applicable threshold and cap allow. Compare the eligible costs against the relevant rule above before filing.

The Ontario Rent Increase Guide covers the AGI process in detail, including the cost thresholds, the evidence requirements, and a calculation sheet for determining whether your situation meets the extraordinary tax threshold.
