Tenant Rights & Landlord Obligations in Ontario

This article is part of our complete guide to leasing in Ontario. It covers the day-to-day side of tenant rights in Ontario, from repairs and heat to deposits and rent increases.

What Tenant Rights in Ontario Does the Law Protect?

The Residential Tenancies Act, 2006 protects tenant rights in Ontario for most residential rentals. That includes a Mississauga condo and a basement apartment in St Catharines alike. The Act requires the landlord to maintain the unit, supply vital services and give notice before entering. It also sets strict rules on rent, deposits and evictions. In return, the tenant must pay rent on time, keep the unit reasonably clean and repair damage they cause.

There’s one important exception. The Landlord and Tenant Board’s guide to the Residential Tenancies Act says the Act doesn’t apply if the tenant must share a kitchen or bathroom with the landlord. Under the Act, that exemption covers sharing with the owner or certain close family members, such as a spouse, child or parent, who live in the building. Sharing a kitchen with other tenants doesn’t remove the Act’s protection on its own. The Act has other exemptions too, so check before assuming it doesn’t apply.

Most disputes we see don’t start with bad intentions. Instead, they start with an assumption. Some people think a lease clause overrides the Act, or that rent can be held back. Others think a lease simply ends when its term is up. None of those is true in Ontario.

What Are a Landlord’s Obligations for Repairs?

An Ontario landlord must keep the unit and the building in good repair and meet health, safety and maintenance standards. That covers the structure, plumbing, heating, electrical systems and any appliances the lease includes. According to the Board’s guide, this applies even if the tenant knew about the problem when they signed.

Responsibility runs both ways, though. The tenant must keep the unit reasonably clean and repair or pay for damage they or their guests cause. However, a tenant isn’t responsible for normal wear and tear, such as faded paint or a worn carpet.

Tenant Rights in Ontario When Repairs Aren’t Done

Put every repair request in writing, with photos and dates. A text can work as a record, but a dated letter or email is far easier to prove at a hearing. Then allow a reasonable time. A furnace failure in January calls for an immediate response, while a loose cabinet door can wait.

If nothing happens, a tenant can file a T6 application about maintenance with the Board. The Board can order the work done and may reduce the rent for the period the problem lasted. What a tenant shouldn’t do is stop paying rent over repairs. The Board’s guide warns that a tenant who withholds rent without the Board’s approval can be evicted.

That warning carries more weight since September 21, 2026. Under the changes now in force at the Board, the rules at an arrears hearing are stricter. If a landlord files for unpaid rent on or after that date, the tenant must pay the landlord half the arrears claimed before raising repair or other issues. That payment, along with a written list of the issues, is due at least seven days before the hearing.

Which Vital Services Do Tenant Rights in Ontario Cover?

Vital services in Ontario are heat, electricity, fuel, gas, and hot and cold water. A landlord can’t shut off or interfere with any of them, even when the tenant owes rent. Cutting a service to pressure a tenant is one of the most serious breaches of the Act. In that case, the tenant can apply to the Board on a T2.

Minimum Heat Rules for Tenants in Ontario

For heat, the Board’s guide sets the vital service period from September 1 to June 15. The province’s maintenance standards require at least 20°C in living areas. Many municipalities, though, set their own rules in a property standards bylaw. For example, Toronto’s heating bylaw requires at least 21°C from October 1 to May 15 where the landlord supplies heat.

So landlords in Mississauga, Hamilton and St Catharines should check their own city’s bylaw before the heating season. Tenants with no heat should contact the landlord in writing first. If the problem continues, call the city’s property standards office.

Air Conditioners in Rental Units

Ontario has also added rules for cooling. Ontario’s guide to renting says a tenant without central air can install a window or portable air conditioner. They must notify the landlord in writing and follow laws such as municipal bylaws. If electricity is included in the rent, the landlord can add a seasonal increase for an air conditioner installed on or after July 1, 2026. According to the Board’s guide, the increase can’t exceed the actual cost of the electricity to run it, or a reasonable estimate. The usual 12-month and 90-day rules don’t apply to this charge, and the rent must drop by the same amount when the unit is removed or no longer used.

What Are Tenant Rights in Ontario Around Privacy and Entry?

A tenant in Ontario has a right to privacy and reasonable enjoyment of their home. In other words, the landlord can’t substantially interfere with how they live there. For most entries, the landlord must give at least 24 hours’ written notice. The written notice must state the reason for entry, the date, and the time of entry, which must be between 8 a.m. and 8 p.m. Repairs, inspections and showings to a potential buyer all fall into that category.

Entry without written notice is allowed only in limited cases. Examples include an emergency, the tenant’s consent at the time, or showings to new tenants after notice to end the tenancy. For those showings, the landlord must enter between 8 a.m. and 8 p.m. and make reasonable efforts to tell the tenant beforehand. Our article on access and showings during a tenancy in Ontario covers each of these rules in detail.

How Much Rent Deposit Can an Ontario Landlord Collect?

An Ontario landlord can collect a rent deposit of no more than one month’s rent or the rent for one rental period, whichever is less. For a weekly tenancy, that means one week’s rent. The deposit can only be used as rent for the last rental period before the tenant moves out. It can’t be held back for damage or cleaning. Every year, the landlord must also pay the tenant interest on that deposit at the rent increase guideline rate.

That rate is 2.1% for 2026 and 1.9% for 2027. Beyond that, a landlord may take a key deposit, but it must be refundable and no more than the expected cost of replacing the keys or fobs. Damage deposits and pet deposits, on the other hand, aren’t allowed.

The landlord also can’t require post-dated cheques or automatic payments, although the two sides can agree to them. In addition, a landlord must give a free rent receipt on request. A former tenant can ask for one up to 12 months after moving out.

How Do Rent Increases Work for Tenants in Ontario?

In most cases, an Ontario landlord can raise the rent only once every 12 months. Seasonal air conditioner charges, covered above, are the main exception. The landlord must also give at least 90 days’ written notice on the proper form. For units covered by rent control, the increase can’t exceed the provincial guideline without the Board’s approval. The guideline is 2.1% for 2026 and 1.9% for 2027.

Units first occupied for residential purposes after November 15, 2018 are generally exempt, so there’s no cap on the increase. However, the 12-month rule and 90-day notice still apply. Many newer condo rentals in Toronto, Mississauga and Burlington fall into this group. That’s why a tenant should ask when the unit was first occupied before signing.

Above-Guideline Increases

A landlord can apply to the Board for an increase above the guideline. Grounds include major capital work such as a new roof, security services, or an extraordinary rise in municipal taxes. Increases for capital work or security services can’t be more than 3% above the guideline in any year. Tenants can attend the hearing and challenge the application.

A tenant charged more than the law allows can apply to the Board on a T1 for a rebate. Timing matters here, so tenants who suspect an illegal increase should apply as soon as possible rather than wait.

Can a Lease Override Tenant Rights in Ontario?

No, a lease can’t override tenant rights in Ontario. Most private residential tenancies entered into on or after April 30, 2018 must use the Ontario Standard Lease. If a tenant asks in writing and doesn’t receive it within 21 days, they can withhold one month’s rent. If the landlord still hasn’t provided it 30 days after the tenant withheld that rent, the tenant doesn’t have to repay it. Still, they can’t withhold more than one month.

Any term that conflicts with the Act is void, even if both sides signed it. For example, a clause banning pets is void. A condo corporation’s own rules, however, can still restrict pets in that building. Clauses banning overnight guests or making the tenant pay for all repairs don’t hold up either. For the full list, read our articles on illegal lease clauses in Ontario and Ontario lease clauses.

Can a Landlord Evict a Tenant Without the Board?

No. An Ontario landlord can end a tenancy only for a reason the Act allows, using the right notice. If the tenant doesn’t leave, the landlord needs an eviction order from the Board. Only the Sheriff can enforce that order. A lease doesn’t end just because its term is up; it continues month to month on the same terms.

Changing the locks, removing a tenant’s belongings or cutting off utilities to force someone out is illegal. Since July 1, 2026, the maximum fine for an offence under the Act is $100,000 for an individual. For a corporation, it’s $500,000, as Ontario’s renting guide confirms.

Tenant Rights in Ontario: Rule Changes Since September 2026

Several rules affecting landlords and tenant rights in Ontario changed on September 21, 2026. First, an N4 notice for unpaid rent now gives 7 days to pay instead of 14. Second, persistent late payment has a definition. It means rent received over seven days late at least three times in six months. Other patterns of late payment may also qualify, so this isn’t a seven-day grace period. Finally, a landlord giving at least 120 days’ notice on an N12 for their own use no longer owes compensation. That exception doesn’t apply to an N12 given for a purchaser’s own use.

We cover these notices in our articles on how residential leases end in Ontario and N12 notices in Ontario. If you plan to sell a rented home, also read about selling a tenanted property in Ontario.

How Do Tenants Enforce Their Rights in Ontario?

Tenants enforce their rights in Ontario by documenting the problem and asking the landlord in writing to fix it. If that fails, they apply to the Landlord and Tenant Board. Here’s the order we suggest:

• Document it. Keep photos, dates, and copies of every message and notice.
• Write to the landlord. Describe the problem and what you’re asking for, and keep a copy.
• Allow a reasonable time. Emergencies such as no heat or flooding need an immediate response.
• Choose the right application. Use a T6 for maintenance and a T1 for money owed. A T2 covers interference, illegal entry, harassment and vital services.
• Prepare for the hearing. Bring your timeline, photos and copies of your written requests.

A T1, T2 or T6 costs $48 through the Tribunals Ontario Portal, or $53 otherwise, according to the Board’s fees page. A tenant who can’t afford the fee can file a fee waiver request. Meanwhile, a landlord’s L1 or L2 application costs $186 online or $201 on paper.

Landlord Obligations When a Tenant Breaks the Rules

Landlords follow the same discipline. First, record the problem. Next, serve the correct N-form, such as an N4 for unpaid rent or an N5 for damage. Then check that notice’s instructions for when you can file. An L1 for unpaid rent comes after the N4 period ends, but the waiting rules for an L2 depend on the notice and the grounds. A wrong form can send a landlord back to the start, so many hire a licensed paralegal.

What Mistakes Cost Landlords and Tenants the Most?

The most expensive mistakes we see landlords and tenants make are avoidable. Here are the ones that come up most often:

• Withholding rent over repairs. It risks eviction and, since September 2026, can limit what a tenant can raise at an arrears hearing.
• Entering without written notice. Even a friendly maintenance visit can count as illegal entry.
• Collecting illegal deposits. Damage and pet deposits aren’t allowed, whatever the lease says.
• Using a homemade lease. Most new tenancies must use the Ontario Standard Lease.
• Leaving without proper notice. Tenants usually need 60 days’ written notice, ending on the last day of a rental period.
• Not reviewing the rent for years. A large gap from market rent can complicate a later sale.
