Ontario Landlord-Tenant Law: Key Rights and Responsibilities

A clear breakdown of landlord and tenant rights under Ontario's Residential Tenancies Act. Know your obligations and protect yourself legally.
Ontario's landlord-tenant laws are some of the most detailed in Canada. Whether you're a first-time landlord or a seasoned property owner, understanding these rules isn't optional. It's the foundation of everything you do.
The Residential Tenancies Act (RTA): Your Bible
The Residential Tenancies Act, 2006 is the primary legislation governing rental housing in Ontario. It covers everything from rent increases to evictions, maintenance obligations to privacy rights.
If you own rental property in Ontario, you need to know this law. Not all of it, necessarily, but the parts that affect your day-to-day operations. Let's break it down.
Landlord Rights
Yes, landlords have rights too. Here are the key ones:
Right to Collect Rent
You're entitled to receive rent on the agreed-upon date. If rent is late, you can serve an N4 Notice to End a Tenancy Early for Non-payment. The tenant then has 14 days to pay the full amount or vacate.
Right to Enter the Unit
You can enter a rental unit, but only under specific circumstances:
- 24 hours written notice for inspections, repairs, or showing the unit (between 8 AM and 8 PM)
- Without notice only in emergencies or if the tenant consents at the time of entry
- To show the unit to prospective tenants after a notice of termination has been given
Right to Reasonable Enjoyment of Your Property
Tenants cannot damage your property, disturb other tenants, or engage in illegal activities. If they do, you have grounds to take action through the LTB.
Right to Increase Rent
You can increase rent once every 12 months with at least 90 days' notice using an N1 form. The increase is limited to the provincial guideline (2.5% for 2024) unless your unit is exempt or you apply to the LTB for an above-guideline increase.
Landlord Responsibilities
Rights come with obligations. Here are yours:
Maintain the Property
You must keep the rental unit and the building in a good state of repair. This includes:
- Structural integrity, plumbing, heating, and electrical systems
- Compliance with health, safety, and maintenance standards
- Working smoke detectors and carbon monoxide detectors on every floor
- Adequate heat (minimum 20 degrees Celsius from September 1 to June 15)
You can't avoid maintenance because a tenant is behind on rent. These are separate obligations.
Provide the Standard Lease
Since April 30, 2018, most residential landlords must use the Ontario Standard Lease. If you don't provide one within 21 days of a tenant's written request, the tenant can withhold one month's rent.
Respect Tenant Privacy
A rental unit is the tenant's home. You cannot:
- Enter without proper notice (except emergencies)
- Install cameras in private areas
- Monitor tenant activities
- Share tenant information without consent
Return the Rent Deposit
In Ontario, you can only collect a last month's rent deposit, not a damage deposit. This deposit can only be applied to the last month of the tenancy. You must pay interest on this deposit annually at the guideline rate.
Tenant Rights
Understanding tenant rights helps you avoid costly mistakes:
Right to Quiet Enjoyment
Tenants have the right to reasonable enjoyment of their unit without interference from the landlord. This is broad and includes freedom from harassment, unreasonable entry, and disruption of services.
Right to Maintenance
Tenants can file a T6 Application with the LTB if you fail to maintain the property. The LTB can order you to make repairs and may reduce rent until they're completed.
Right Against Illegal Lockouts
Even if a tenant owes months of rent, you cannot change the locks or physically remove them. Only the Sheriff can enforce an eviction order from the LTB.
Right to Assign or Sublet
Tenants can request to assign their lease or sublet the unit. You can't unreasonably refuse. If you do, the tenant may be able to end the tenancy on 30 days' notice.
The Ontario Standard Lease
The standard lease is a government-created form that ensures certain rights can't be contracted away. Key points:
- Illegal clauses are void. Even if a tenant signs a clause banning pets or guests, it's unenforceable.
- No-pet clauses are generally void (with exceptions for condos with no-pet rules).
- Post-dated cheques cannot be required.
- Automatic rent increases beyond the guideline are void.
Rent Deposit Rules
This trips up many new landlords. In Ontario:
- You can collect a last month's rent deposit (LMR) equal to one month's rent
- You cannot collect a security or damage deposit
- The LMR must be applied to the tenant's last month only
- You must pay interest on the deposit each year at the guideline rate
- You can collect a key deposit only for the actual cost of replacing keys
Staying Organized and Compliant
Compliance is much easier when you're organized. Keeping track of notice periods, deposit interest, maintenance requests, and lease terms manually is a recipe for mistakes.

Common Mistakes to Avoid
- Collecting a damage deposit. It's illegal in Ontario. Period.
- Not using the Standard Lease. This can cost you a month's rent.
- Entering without notice. Even for "quick checks," you need 24 hours notice.
- Retaliating against tenants who exercise their rights (like filing a maintenance complaint).
- Issuing an N12 in bad faith. Using a personal-use eviction when you don't actually plan to move in can result in fines up to $50,000.

When in Doubt
The RTA is complex. When you're unsure about a situation, consult the Landlord and Tenant Board's website or seek legal advice. The cost of a consultation is nothing compared to the cost of getting it wrong.
Knowledge is your best protection. Stay informed, stay organized, and treat your rental properties like the business they are.
