Ontario Rent and Deposit Laws: Tenant Guide 2024

Rent & Deposits Ontario published July 01, 2025

Navigating rent and deposit laws is essential for every tenant in Ontario. Understanding your rights can help prevent disputes and ensure your rental experience is fair and transparent. Ontario’s Residential Tenancies Act, 2006 shapes the rules around how much landlords can charge, what deposits are legal, and how your payments must be handled. This guide explains the essentials you need to know in plain, up-to-date terms, so you can rent with confidence.

How Rent Works for Tenants in Ontario

Rent is the agreed amount you pay to live in your home each month. The law in Ontario protects you from sudden, unfair increases or charges you didn't agree to in advance.

Monthly rent is fixed: Your landlord cannot ask you to pay extra charges outside the rental agreement, except for utilities you have agreed to, parking, or services you contract separately.
Rent increases are regulated: Landlords can only raise the rent once every 12 months by giving you at least 90 days’ written notice. The increase must follow the annual guideline set by the province, unless approved otherwise by the Landlord and Tenant Board.
Receipts: You can request a receipt for any rent or deposit payment, and your landlord must provide one without charge.

Legal Rental Deposits in Ontario

Rental deposits are a common source of confusion and disputes. Ontario law limits what deposits landlords can collect and how these must be managed:

Last Month’s Rent (LMR) deposit only: Landlords can only ask for a deposit equal to one month’s rent. This deposit is applied to your last month, not as damage security.
No security/damage deposits: Unlike some other provinces, Ontario does not allow landlords to charge you a separate deposit for potential damages or cleaning.
Deposit interest: Landlords must pay annual interest on your LMR deposit at the rate set each year by the province. This is usually applied as a deduction from your rent.

Key Forms for Rent and Deposits

N1 Notice to Increase Rent: Used when your landlord wants to raise your rent. You must receive this form at least 90 days before the new rent takes effect.
Official N1 form and guide.

If you get an N1, check that the increase matches the legal guideline. If it doesn’t, you can dispute it with the Landlord and Tenant Board.
Rent Receipt: You have the right to request a receipt for any rent or deposit payment. This can help you if a dispute arises later.

Ontario’s Landlord and Tenant Board (LTB) handles all dispute resolutions and official forms.

Common Questions About Rent and Deposits

The rules around rent and deposits aim to balance tenant protection with fair landlord practices. Here’s a quick summary:

If your landlord collects more than one month’s deposit or tries to charge a deposit not related to last month’s rent, this is not allowed.
If you don’t pay full rent, your deposit does not cover unpaid monthly rent until your last month in the unit.
Annual rent increases can’t exceed the legal guideline unless the landlord applies for an exception.
