Above-Guideline Rent Increase in Ontario: The AGI Guide

A standard rent increase in Ontario is capped at the guideline (2.1% for 2026) and is served on the tenant with an N1 notice at least 90 days before it takes effect. No Board involvement is required — you just have to follow the timing and the 12-month rule.

An above-guideline increase is different in kind, not just degree. It is an application to the LTB asking the Board to authorize an increase higher than the guideline. You file it, the tenants are notified, and an adjudicator decides — often after a hearing — whether the increase is justified and how much of it is allowed.

The three valid grounds

An AGI is only available on one or more of three grounds. If your situation does not fit one of these, you cannot apply.

The most common reason an AGI application fails is that the work claimed is not actually an eligible capital expenditure. The Board draws a hard line between major repairs that preserve the building and routine work, cosmetic upgrades, or value-adding renovations done for their own sake.

A useful test: would this work fail to protect the physical integrity of the building or the operation of a major system if you did not do it? If the answer is no — if it is a nice-to-have rather than a need-to-do — it is unlikely to qualify as a capital expenditure for AGI purposes.

The single most important number in AGI planning is the cap on capital-expenditure increases. An AGI for eligible capital work is limited to a maximum of 3% above the guideline in any single year.

Here is how the phase-in works in practice. Suppose the LTB approves a capital-expenditure increase that, in total, justifies more than 3% above the guideline. You cannot collect all of it in year one. Instead, you apply up to the 3% cap in the first year, and the balance carries into the second year (and, if needed, a third), each year still subject to the cap. The full approved amount can be spread across up to three years.

You apply for an above-guideline increase by filing Form L5 (Application for a Rent Increase Above the Guideline) with the Landlord and Tenant Board. The form requires you to identify the ground, the units affected, and the costs you are claiming — backed by documentation.

• 01Choose the ground (extraordinary taxes, capital expenditures, or security services) and identify every rental unit the increase will apply to.
• 02Assemble your evidence: invoices, contracts, proof of payment, photographs of the work, and tax bills as applicable. Incomplete documentation is the most common reason applications stall.
• 03File Form L5 with the LTB and pay the application fee. There are timing rules tying the application to when the work was completed and paid.
• 04The LTB notifies the affected tenants of the application. Tenants have the right to review the claimed costs and to dispute the application.
• 05A hearing is scheduled. Tenants can attend, question the claimed costs, and argue that work does not qualify or that amounts are overstated.
• 06The adjudicator issues an order: approving, reducing, or denying the increase, and setting any phase-in.

Crucially, the L5 order does not by itself raise the rent. Once the Board approves an increase, you still deliver it to each tenant through the ordinary rent-increase notice process, with at least 90 days' notice and respecting the 12-month rule between increases for each tenant.

An AGI is not fast. Between assembling documentation, filing, the Board notifying tenants, scheduling a hearing, holding it, and waiting for the order, the process commonly runs for many months from start to finish. Building in a phase-in across multiple years extends the horizon further.

LTB hearing wait times vary and have been a persistent pressure point for the Board, so it is wise to assume the schedule is outside your control and to plan for a long runway rather than a quick turnaround. Treat any specific timeframe you hear as an estimate, not a guarantee.

AGIs are document-heavy, slow, and contested. Tenant advocacy groups actively help tenants challenge them, and a single weak invoice or a questionable line item can lead the adjudicator to reduce the approved amount. Before you commit, do the math on effort against payoff.

When an AGI tends to make sense

When it usually is not worth it

Units first occupied for residential purposes after November 15, 2018 are exempt from the rent increase guideline entirely. For these units there is no 2.1% ceiling on annual increases between tenancies' sitting tenants — and therefore no need to apply for an AGI, because there is no guideline cap to exceed in the first place.

If your unit is post-November 15, 2018 and you were considering an AGI, stop — the AGI machinery is for rent-controlled units that are bound by the guideline. Confirm your unit's status before assuming either path applies.
