Last Month’s Rent Rules for Tenants in Ontario

Maintenance & Repairs Ontario 4 min read · published March 09, 2026 Flag of Ontario

For tenants in Ontario, understanding last month’s rent is important when starting or ending a tenancy. This guide explains what the deposit is, how it can be used, when it may need to be topped up, and how to protect your rights under Ontario’s laws.

What Is Last Month’s Rent in Ontario?

When starting a new tenancy, a landlord in Ontario can request a payment equal to one month’s rent. This is called a last month’s rent deposit. It is separate from your regular rental payments and is used for your final month in the rental unit.

Legal Framework and Protections

  • Ontario’s Residential Tenancies Act, 2006 governs the collection, use, and return of last month’s rent.
  • The Landlord and Tenant Board of Ontario handles disputes and questions about residential tenancies.
  • A landlord cannot require more than one month’s rent as a deposit. The deposit must be used for your last month’s rent during the tenancy.
If a landlord demands additional deposits, such as deposits for keys or cleaning, this violates Ontario law. You can politely refuse and cite Section 106 of the Residential Tenancies Act.

How Last Month’s Rent Deposit Is Used

  • The deposit is held during the tenancy and is applied to your final month in the rental unit.
  • If rent increases while you live in the unit, your landlord can ask you to top up the deposit so it matches the new monthly rent.
  • The deposit cannot be used for damages, cleaning, unpaid utilities, or other costs. It is for rent only.
Interest on last month’s rent matches Ontario’s Rent Increase Guideline. The rate was 1.2% in 2024. Landlords must credit this interest annually, so ask about it if it has not been provided.

These rules mean that the deposit should not be withheld for costs unrelated to your final month’s rent.

Top-Up Requirements When Rent Increases

When your rent increases, the landlord can request the difference needed to bring your last month’s rent deposit up to the current monthly rent. The landlord must first give proper written notice of the rent increase under Ontario law. For more information, see Understanding Rent Increases: What Tenants Need to Know.

Official Forms for Last Month’s Rent in Ontario

There is no dedicated government-issued form for paying a last month’s rent deposit. The deposit is usually addressed in the lease or rental agreement. A rent increase may involve the following form:

  • Form N1: Notice of Rent Increase (Official Link)
    When and how to use: If the landlord increases the rent and the deposit must be topped up, the landlord must provide Form N1 at least 90 days in advance. For example, if rent increases from $1,000 to $1,030, the landlord can request the $30 difference for the deposit.

Protecting Your Deposit

  • Last month’s rent accrues interest at the rate set annually by the province. The landlord must pay the interest each year, either as a payment or as a reduction in rent owed.
  • If you plan to move out, provide written notice, usually 60 days, to your landlord. The deposit is applied to your last month’s rent.
When giving move-out notice, send it by email or registered mail and keep proof. This can help prevent disputes about whether notice was properly given.

Remember: Your last month’s rent deposit is intended to cover rent for your final month, provided that all legal requirements, including proper notice, are met.

Important Rights and Responsibilities for Tenants

  • Pay only the last month’s rent deposit required by Ontario law, not additional deposits.
  • Keep copies of receipts, the lease, your move-out notice, and communications about the deposit or rent increases.
  • The landlord must use the deposit for your final month’s rent and not for damages, cleaning, or other costs.

Moving Out: How the Last Month’s Rent Is Applied

After you give legal notice, the last month’s rent deposit is applied to your final month’s rent. If your tenancy ends unexpectedly or you are unsure whether your notice was sufficient, consult the Landlord and Tenant Board to help protect your rights.
