You will find clear steps a renter can take when a landlord gives written notice, practical examples of disputing an illegal or above-guideline increase, and what evidence to gather. Whether you rent a room, condo, or house in Ontario, this article focuses on tenant-friendly actions such as how to review the notice, who to contact for help, and where to file an application if needed.
How rent increases work in Ontario
In Ontario, most rent increases are subject to an annual guideline set by the province and must be given with a minimum 90 days written notice before they take effect. The Residential Tenancies Act, 2006 sets the general rules for increases and when a landlord must get approval from the Landlord and Tenant Board (LTB) for above-guideline increases[1]. Landlords must follow the timing rules and cannot increase rent more than once in a 12-month period for the same tenancy.
Limits, exceptions, and above-guideline increases
The guideline applies to most private residential units but there are exceptions. Examples of exceptions include new buildings first occupied after a specific date, most social housing, and situations where a landlord has been approved to raise rent above the guideline for major capital expenditures or serious repairs.
- 90-day written notice is required for any rent increase that is permitted.
- Annual guideline limits how much landlords can increase rent without LTB approval in most cases.
- Above-guideline increases need an approved application to the Landlord and Tenant Board.
Example: what an above-guideline application looks like
A landlord who spends money on major capital repairs to plumbing or heating may apply to the LTB to recover part of that cost by raising rent above the guideline; the tenant will get notice of the application and can participate in the hearing.
If you receive a rent increase notice
When you get written notice, check the following details immediately: the effective date, the new rent amount, whether the increase complies with the 12-month rule, and whether the landlord claims an exemption or LTB approval.
- Keep the notice and any emails or messages from your landlord as records.
- Compare the increase to the provincial guideline to see if it looks legal.
- Ask your landlord for clarification in writing if anything is unclear; keep copies.
Disputing an increase
If you believe an increase is illegal or the landlord failed to follow rules, you can apply to the Landlord and Tenant Board. The LTB handles disputes about whether a rent increase is valid and whether the correct processes were followed. Use the LTB forms and instructions to submit an application and prepare evidence such as your lease, notices, payment records, and photos if relevant[2].
- Gather evidence: rent receipts, your lease, photographs, and copies of the notice.
- File the appropriate application with the LTB and pay any required fee, or ask about fee relief if you qualify.
- Consider contacting tenant legal clinics or community legal aid if you need help preparing your case.
Practical examples
Example 1: A tenant receives a written notice that rent will rise in 60 days. Because Ontario requires 90 days, the tenant can notify the landlord the notice is invalid and contact the LTB if the landlord insists. Example 2: A landlord proposes a 5% above-guideline increase to recover major capital work; the tenant should request documentation and prepare to participate in the LTB hearing if an application is filed.
