Understanding Rent Increases in Ontario

Rent & Deposits Ontario 3 min read · published March 09, 2026 Flag of Ontario

As a tenant in Ontario, understanding rent increases is crucial for managing your housing expenses and ensuring that your rights are protected. Under the Residential Tenancies Act, 2006, the guidelines surrounding rent increases are set to protect both tenants and landlords, making sure changes are fair and transparent.

Annual Rent Increase Guideline

The Ontario government sets a rent increase guideline each year, which dictates the maximum percentage a landlord can raise the rent without applying for approval from the Landlord and Tenant Board (LTB). For 2023, this figure is set at 2.5%*. This guideline applies to most private residential rental units; however, there are exceptions, including buildings first occupied after November 15, 2018.

Notice for Rent Increase

Landlords must provide tenants with a 90 days written notice of any rent increase using the proper form, such as the "Notice of Rent Increase". This ensures that tenants have ample time to assess their finances or make alternative arrangements if needed.

Keep a copy of the Notice of Rent Increase and the date it was served. If you think the increase is incorrect, write to the landlord with your calculations and records; if unresolved, you can apply to the LTB for review.

How to Use the Notice of Rent Increase Form

  • Landlords must fill out the form with the current rent, the amount of the increase, and the new total rent.
  • The form must be delivered to the tenant at least 90 days before the rent increase takes effect.
  • Tenants should ensure the form is complete and legally meets the rent increase guideline.

For tenants who wish to dispute an increase, it’s important to know the process for challenging a rent increase and when it might be justified under the law.

Disputes can be filed with the LTB using the appropriate forms; gather your lease, the notice you received, and any correspondence with your landlord, then submit your application if you believe the increase is above the guideline or not properly issued.

Exceptions to the Guideline

Certain circumstances allow landlords to apply for a rent increase above the guideline. Reasons might include significant capital work on the rental, improvements, or increased utility costs. Such cases require landlords to apply to the Landlord and Tenant Board for approval, and tenants will have the opportunity to challenge these applications.

Above-guideline increases require LTB approval; tenants can challenge by reviewing the landlord’s application and presenting supporting documents, such as receipts for capital work or utility cost changes.
