Understanding how rent increases work can help tenants in Ontario protect their budget and rights. This article explains when landlords can raise rent, how much advance notice is required, what limits the law sets, and what steps a renter can take if they believe an increase is unlawful. Practical tips cover documentation, responding to notices, and when to contact the Landlord and Tenant Board or a local tenant service. Examples show how to use official forms and timelines, and we explain common exceptions such as new-build units or added services. Read on for clear, tenant-focused guidance so you can respond confidently to rent increases in Ontario.
How rent increases work in Ontario
In Ontario, most private residential rents are regulated by the Residential Tenancies Act, 2006, which limits how often and how much rent can be raised for occupied rental units. Landlords must follow the guideline set by the province for yearly increases unless the unit is exempt (for example, newly built units occupied for the first time after a specific date). Tenants have rights to proper written notice and to challenge increases that appear to be illegal or retaliatory. For details and official guidance, see the Landlord and Tenant Board [1] and the Residential Tenancies Act [2].
When a landlord can increase rent
A landlord can increase rent only once every 12 months for an existing tenancy and must provide the required written notice. Common lawful reasons include regular annual increase under the guideline or changes agreed in a lease for a future term. Exemptions include specific categories such as newly built units or certain care homes; always check whether an exemption applies to your unit.
Exceptions and special cases
- If the unit is a new-build or otherwise exempt, the annual guideline may not apply.
- If a landlord adds new services (for example, included utilities or parking), they may adjust the total rent.
- If the landlord seeks above-guideline increases for capital repairs, they must apply to the Landlord and Tenant Board.
Notice requirements and timelines
Landlords must provide a written notice of rent increase at least 90 days before the increase takes effect. The increase cannot take effect until 12 months have passed since the last rent increase for that unit. Notices must be clear, dated, and include the new rent amount and the effective date.
What to check on a notice
- That the notice is in writing and dated with the effective increase date.
- That the effective date is at least 90 days after the notice and at least 12 months since the last increase.
- That the calculation of the new rent amount is clear and matches any written agreement or advertised terms.
If a notice is missing required elements or the timelines are not met, the increase may be invalid and you can challenge it.
What to do if you receive a rent increase
Take these practical steps: review the notice carefully, compare it to your lease, gather evidence of prior rent payments and any communications, and consider discussing the increase with your landlord if you have questions. If you suspect the increase is unlawful or retaliatory, you can apply to the Landlord and Tenant Board to dispute it.
- Document recent rent payments, receipts, and the landlord's notice.
- Contact tenant support services or the Landlord and Tenant Board for clarification on your rights.
- Respond in writing within any practical timeline to request more information or to record your disagreement.
