Ontario Landlord Responsibilities: The Complete 2026 Legal Checklist

Updated: June 23rd 2026

When you are a landlord in Canada, you need to be sure that the unit that you rent out is aligned with the regulations and rules regarding maintenance, safety, and health. You may ask, “As a landlord, what are my rights?” The Residential Tenancies Act outlines the obligations that come with leasing a home to tenants in Ontario.

We’ve compiled all the necessary information that you need to know. Let’s dive in!

What is the Residential Tenancies Act (RTA)?

The Residential Tenancies Act, in short, the ‘Act,’ is an Ontario law that covers tenant and landlord responsibilities as well as landlord and tenant rights in Ontario. This law provides essential information about the rules, and its goal is to protect residential tenants from illegal evictions and rent increases, as well as establish obligations for residential rents. This way, the law can balance tenant rights and landlord responsibilities in Ontario and resolve disputes between them. People who live in rental housing are covered by the RTA, and it doesn’t apply to people who live in prison, emergency shelters, nursing homes or hospitals, units that are used temporarily or seasonally, student dormitories or residents, etc. 

Landlords who violate tenants’ rights or don’t complete their obligations, such as charging extra fees, harassment, preventing the delivery of heat, water, or electricity, etc., can be subject to an offence. Once the tenant feels like the landlord or their employee is violating tenant rights, they can complain to the Rental Housing Enforcement Unit (RHEU). Once the complaint is made, the RHEU will examine the issues and will try to find solutions to them. 

Owning a rental property in Ontario comes with significant legal obligations – and the penalties for getting them wrong can be steep. A single LTB order against you can cost thousands of dollars, force you to provide rent abatements, or result in administrative fines under the Residential Tenancies Act (RTA). In more serious cases, a landlord can face a $50,000 fine under the Fire Protection and Prevention Act for something as straightforward as a missing smoke alarm.

The reality is that most compliance failures aren’t deliberate. Landlords run into trouble because Ontario’s rental rules are spread across multiple pieces of legislation – the RTA, the Ontario Building Code, municipal property standards bylaws, the Human Rights Code, and fire safety regulations – and nobody hands you a plain-language summary when you buy your first rental property.

This checklist does exactly that. Below is a complete breakdown of every major legal duty Ontario landlords carry under the RTA and related legislation, updated for 2026, so you can protect your investment and stay on the right side of the Landlord and Tenant Board.

1. Maintenance & Repair – RTA Section 20

This is the cornerstone of your obligations as an Ontario landlord. Under RTA Section 20, you are legally required to maintain your rental property in a good state of repair, fit for habitation, and compliant with health, safety, and housing standards – even if the tenant was aware of any deficiencies before signing the lease.

That last part matters more than most landlords realize. A lease clause stating “tenant accepts the unit as-is” or “tenant is responsible for all maintenance” is completely unenforceable under Ontario law. You cannot contract out of your repair obligations, regardless of what both parties agreed to in writing.

What “Good State of Repair” Means in Practice

The standard isn’t perfection – it’s habitability and safety. A good-state-of-repair property includes:

• Structural soundness: roof, walls, foundation, ceilings, and floors
• Functioning plumbing, electrical systems, and HVAC
• Working doors, windows, and locks – including exterior security
• Pest-free conditions (you are responsible for extermination unless the tenant caused the infestation through their own conduct)
• Common areas kept clean, well-lit, and free of hazards
• Appliances included in the lease agreement in working order

One important nuance: if an appliance was provided with the unit as part of the tenancy agreement (even if it’s older), you are responsible for maintaining or replacing it. If the tenant brought their own appliance and it breaks down, that’s their responsibility.

Repair Response Time Expectations

The RTA doesn’t prescribe exact timelines, but the LTB evaluates what’s “reasonable” based on the urgency of the situation:

• Emergency repairs – no heat in winter, burst pipe, gas leak, loss of hot water: respond the same day, within hours where possible
• Urgent but non-emergency repairs – broken oven, plumbing drip, malfunctioning lock: within 24–72 hours
• Non-urgent repairs – cosmetic damage, minor fixture issues: within a reasonable period, typically 7–14 days

Delayed repairs are consistently one of the top reasons tenants file T6 Maintenance Applications at the LTB, often resulting in a rent abatement – a retroactive rent reduction you have to pay back for the period the issue went unresolved. Documenting your repair requests and your response times is essential protection.

If a repair emergency happens in the middle of the night, your obligations don’t pause until business hours. Understanding exactly when you’re legally required to respond to after-hours tenant emergencies is something every Ontario landlord needs to know before a crisis hits.

Our emergency property management service handles urgent repair coordination around the clock, so your tenants get a response and you stay protected.

2. Providing Essential Services – RTA Section 21

Under RTA Section 21, a landlord must not withhold or interfere with the supply of any vital service they are contractually responsible for providing. This applies to heat, electricity, gas, hot and cold water, and air conditioning where it is central to the unit.

This is one of the most serious obligations in the RTA. Cutting off essential services – even as pressure to collect unpaid rent – is illegal and can result in an urgent LTB application by the tenant, an immediate restoration order, and significant financial penalties against you.

Ontario’s minimum heating standard: Indoor temperatures must be maintained at a minimum of 21°C from September 1 to June 15. Toronto’s municipal bylaw sets the standard even higher at 21°C year-round in occupied rental units, with a cooling standard of 26°C during summer months.

If a tenant falls behind on rent, the correct legal process is to issue an N4 (Notice to End Tenancy for Non-Payment of Rent) and file an L1 application at the LTB if the arrears aren’t resolved. Interrupting heat or water is never a legal alternative – and it tends to result in far greater costs than the rent arrears themselves.

3. Right of Entry – The 24-Hour Written Notice Rule

Under RTA Section 27, you have the right to enter your rental unit – but only under specific conditions and for specific purposes. The standard rule is:

• Written notice must be given at least 24 hours in advance
• Entry must occur between 8 a.m. and 8 p.m.
• The notice must state the specific reason for entry and the date and approximate time you plan to enter

Slipping a verbal heads-up or a text message to your tenant the morning of the visit does not meet this requirement. The notice must be in writing, and it must give a full 24 hours – not “sometime tomorrow.”

Permitted Reasons for Entry

• Carrying out a repair, inspection, or maintenance
• Showing the unit to prospective tenants or purchasers
• An emergency where immediate entry is necessary to prevent harm or serious damage
• Any other reason permitted under the RTA (e.g., an agreed-upon purpose)

When You Can Enter Without Notice

The only exception to the 24-hour rule is a genuine emergency – a fire, flooding, gas leak, or a situation where waiting would cause serious harm to someone or significant property damage. This exception is deliberately narrow. A non-functioning appliance or a routine inspection you forgot to schedule does not qualify.

Repeated entry without proper notice, or entry at unreasonable hours, is one of the most common grounds for a T2 application (tenant harassment) at the LTB. Even well-intentioned landlords have faced rent abatements and fines for this.

When you need routine or move-out inspections done correctly and documented in a way that will stand up if challenged, our professional property inspection service handles the entire process in full compliance with RTA entry requirements.

4. Rent Receipts and Rent Increases

Rent Receipts

Under RTA Section 109, you must provide a rent receipt to any tenant who pays in cash and requests one. Best practice is to issue receipts for every payment method – it creates a clear paper trail and protects you if a dispute ever arises about what was paid and when.

The 2026 Rent Increase Guideline

Ontario’s rent increase guideline for 2026 is 2.5%. This is the maximum percentage you can raise rent for most existing tenants in a given year without filing an Above Guideline Increase (AGI) application at the LTB.

Key rules every Ontario landlord must follow when raising rent:

• You must give at least 90 days’ written notice before the increase takes effect – not 89, not 85
• You can only raise rent once every 12 months per tenancy
• Notice must be given on the official N1 form from the LTB – a letter or email is not sufficient
• Rent control applies to units first occupied for residential purposes before November 15, 2018
• Units first occupied after November 15, 2018 are exempt from rent control – you can increase by any percentage – but the 90-day notice requirement and 12-month cap on frequency still apply

One mistake landlords make with newer builds: assuming the rent control exemption means fewer rules overall. The process requirements are identical; only the percentage ceiling changes.

For a step-by-step walkthrough of how to properly serve a rent increase notice in Ontario – including what voids an N1 and how to avoid a successful tenant challenge – that post covers every detail.

Keeping track of guideline changes, preparing compliant N1 notices, and making sure increases go out on time is exactly the kind of task that slips through the cracks for self-managing landlords. Our rent collection and rent management service handles all of it.

5. Privacy and Quiet Enjoyment – RTA Section 22

Under RTA Section 22, you must not substantially interfere with a tenant’s reasonable enjoyment of the rental unit or the residential complex. This provision – commonly called the right to “quiet enjoyment” – applies to your conduct as a landlord, the conduct of people you’re responsible for, and conditions in the building that are within your control to fix.

Quiet enjoyment violations that landlords are most commonly found guilty of at the LTB:

• Harassing, threatening, or pressuring a tenant to vacate outside of a legal eviction process
• Repeatedly entering the unit without proper 24-hour notice
• Failing to address persistent noise, pests, or disrepair that substantially disrupts the tenant’s use of the unit
• Removing appliances, changing locks, or interfering with access to the unit or common areas
• Allowing renovations to drag on without a reasonable timeline or interim accommodation

A T2 Application filed by a tenant for interference with quiet enjoyment can result in a rent abatement, a fine of up to $50,000 for an individual landlord, and an order requiring you to stop the offending conduct. These penalties aren’t theoretical – the LTB issues them regularly.

Many quiet enjoyment violations stem from landlords not fully understanding where the legal lines are in Ontario landlord-tenant relations. That post is worth reading before you find yourself in a dispute.

6. Property Standards and Safety Compliance

The RTA governs the landlord-tenant relationship, but your property also has to comply with Ontario’s Building Code, Fire Code, and municipal property standards bylaws. These rules exist independently of the RTA – meaning a tenant doesn’t need to file at the LTB to trigger a property standards inspection. They can call the city directly.

Smoke Alarms

• Required on every storey of the unit and outside every sleeping area
• Must be tested and confirmed working at the start of each new tenancy
• Landlords who fail to install or maintain working smoke alarms face fines of up to $50,000 under the Fire Protection and Prevention Act

Carbon Monoxide Alarms

• Required adjacent to every sleeping area in units with a fuel-burning appliance (gas furnace, gas stove, fireplace) or an attached garage
• Must be tested at the same time as smoke alarms at every tenancy turnover

Fire Egress

All exit routes must be unobstructed and in working order at all times. This connects directly to tenant conduct issues like hoarding – where a tenant creates a blockage, the landlord still faces exposure if a bylaw officer or fire marshal visits and finds the exit compromised.

Electrical Safety

Wiring, panels, and outlets must meet the Ontario Electrical Safety Code. After major electrical work, an ESA inspection certificate may be required before the work is considered complete. Older properties in particular should be reviewed periodically for compliance.

Municipal property standards vary: Toronto, Mississauga, Brampton, Hamilton, and other municipalities each maintain bylaws that can exceed provincial minimums on things like exterior maintenance, window condition, temperature standards, and lighting. Check with your local municipality for the specific requirements that apply to your property.

The gap between what landlords think the rules are and what the rules actually are is significant. The most common compliance mistakes Ontario landlords make often involve exactly these property standards requirements – and they’re avoidable with the right process in place.

7. Responsibilities When a Tenant Vacates

Move-out is one of the highest-risk points in any tenancy. Disputes over the condition of the unit, the return of deposits, and damage charges are common – and without proper documentation, landlords often lose at the LTB even when they’re in the right.

Last Month’s Rent Deposit Rules

Ontario does not allow security deposits or damage deposits. The only deposit you are legally permitted to collect is a last month’s rent (LMR) deposit, and it must be applied to the final month of rent – not to repair damages, cleaning costs, or any other expense.

You are legally required to pay annual interest on the LMR deposit. The rate tracks the rent increase guideline each year, which means the interest owed for 2026 accrues at 2.5%. This can be either paid directly to the tenant or credited against the last month’s rent calculation when the tenancy ends. Landlords who fail to track and pay this interest can face an LTB application from the tenant to recover it.

The Move-Out Inspection

Conduct a documented move-out inspection as soon as possible after the tenant vacates – ideally on the same day. Compare the unit’s condition against your move-in inspection records, with date-stamped photographs of both. This documentation is your primary protection if you intend to pursue the tenant for damages beyond normal wear and tear at the LTB.

A critical point: normal wear and tear – minor scuffs on walls, carpet compression from furniture, small nail holes – is your cost, not the tenant’s. Only damage that goes beyond ordinary use can be claimed. The LTB draws this line carefully, and “it looked better before they moved in” is not enough without documented evidence of the specific damage and its repair cost.

Our move-in and move-out management service handles condition reports, photographic documentation, key collection, and deficiency recording at both ends of a tenancy – giving you the paper trail you need if a dispute ever lands at the LTB.

Landlord vs Tenant Responsibilities – At a Glance

Understanding where your obligations end and the tenant’s begin prevents a significant portion of disputes. Here’s a clear breakdown:

Responsibility	Landlord	Tenant
Structural repairs and maintenance	✅ Yes	❌ No
Appliances provided with the unit	✅ Yes	❌ No
Appliances brought by the tenant	❌ No	✅ Yes
Pest control (general infestation)	✅ Yes	❌ No
Pest control (tenant-caused infestation)	❌ No	✅ Yes
Ordinary cleanliness of the unit	❌ No	✅ Yes
Smoke and CO alarm installation	✅ Yes	❌ No
Smoke and CO alarm testing during tenancy	✅ At turnover	✅ Ongoing
Common area maintenance and lighting	✅ Yes	❌ No
Utilities included in rent	✅ Yes	❌ No
Notifying landlord of needed repairs	❌ No	✅ Yes
Damage caused by tenant or guests	❌ No	✅ Yes
Normal wear and tear	✅ Landlord absorbs	❌ Not tenant’s cost
Garbage disposal (unit-specific)	❌ No	✅ Yes
Keeping exits and common areas clear	Shared	✅ Yes (unit access)

Frequently Asked Questions

Q: What happens if I don’t make repairs on time in Ontario? A tenant can file a T6 Maintenance Application at the LTB. If the board finds you failed your obligations under RTA s.20, it can order you to carry out the repairs, pay a rent abatement retroactively covering the period the issue existed, and in some cases cover the tenant’s LTB filing costs. Persistent or serious violations can also attract administrative fines.

Q: Can I raise rent by more than 2.5% in 2026? For units subject to rent control – first occupied before November 15, 2018 – the maximum is 2.5% without an Above Guideline Increase (AGI) application to the LTB. For units exempt from rent control – first occupied after November 15, 2018 – there is no percentage cap, but the 90-day N1 notice requirement and the 12-month frequency limit still apply in full.

Q: Am I responsible for repairs if the tenant caused the damage? You are still responsible for completing the repair – the unit must be kept in good repair regardless of who caused the issue. However, you can recover the cost by serving an N5 notice for damage or pursuing the matter at the LTB. The critical distinction the board makes is between ordinary wear and tear (absorbed by the landlord) and damage caused by the tenant or their guests (recoverable from the tenant).

Q: Can I collect a damage deposit in Ontario? No. Ontario prohibits damage deposits entirely. The only deposit you can legally collect is a last month’s rent deposit, and that money can only be applied to the final month of rent – not repairs, cleaning, or any other cost.

Q: How much notice do I need to give before entering a tenant’s unit? At least 24 hours’ written notice, specifying the reason for entry and the planned date and time (between 8 a.m. and 8 p.m.). Emergency entry – for situations involving immediate risk of harm or serious property damage – is the only exception and does not require advance notice.

Q: What is the LTB backlog, and how does it affect landlords in 2026? The LTB has faced persistent hearing delays since 2020. As of 2026, contested applications in some regions are taking six months to over a year to reach a hearing. This makes proactive compliance – staying current on your obligations, documenting everything, and resolving disputes before they escalate – far more valuable than treating the LTB as your first line of response to tenant issues.

Q: Do I have to pay interest on a last month’s rent deposit? Yes. Interest accrues annually at the rent increase guideline rate – 2.5% for 2026. You can pay this directly to the tenant or credit it against the last month’s rent when the tenancy ends. Failing to track and apply this interest is one of the small but consistent mistakes that shows up in LTB applications against landlords.

Let a Professional Handle It

Staying current on every obligation – repair timelines, entry rules, guideline-compliant rent increases, LMR interest, safety inspections, municipal bylaw changes – is more than most landlords bargained for when they bought a rental property. The rules change, the forms change, and the LTB shows little sympathy for landlords who missed a procedural requirement even when their underlying position is reasonable.

Most self-managing landlords eventually miss something. A professional property manager keeps that from becoming an LTB problem.

• Full-service residential property management – End-to-end management that keeps your property compliant year-round. 
• Professional property inspection services – Documented inspections at move-in, move-out, and throughout the tenancy. → Rent collection and increase management – Guideline tracking, N1 preparation, and consistent enforcement.
• Move-in and move-out management z Condition reports and documentation that protect you at both ends of a tenancy.
