Quick Answer

In Ontario, a landlord can only charge an above-guideline increase (AGI) if the Landlord and Tenant Board approves it. AGIs are allowed for eligible capital expenditures, extraordinary increases in municipal taxes, or new/increased security services. An AGI based on capital work is limited to 3% above the annual rent guideline per year and can be phased in over up to three years. A landlord cannot impose an AGI without an LTB order.

📋 About Above Guideline Increases
An AGI lets a landlord apply to the LTB (Form L5) for a rent increase beyond the annual guideline, on three grounds: eligible capital expenditures (major repairs or replacements, like a new roof or elevator), extraordinary increases in municipal taxes or charges, or increased security service costs.
An AGI is not self-executing — a landlord cannot simply decide to charge above the guideline. It requires a successful application and order from the Landlord and Tenant Board, and tenants can dispute the application at a hearing.
The capital-expenditure portion of an AGI is capped at guideline + 3% per year. If the full justified increase exceeds that in a single year, it is phased in at up to 3% per year for up to 3 consecutive years.
🏗️

Capital Expenditures

Major, non-recurring repairs or replacements — not routine maintenance — are the most common AGI ground.

🏛️

LTB Application Required

Form L5 must be filed and approved before any above-guideline amount can be charged.

📆

Phased Over Up to 3 Years

Large capital-expenditure increases are spread out, capped at an extra 3% per year on top of the guideline.

⚖️

Tenants Can Dispute

Tenants receive notice of an AGI application and can raise issues like maintenance history at the LTB hearing.
