Ontario's Residential Tenancies Act, 2006 (RTA) governs the relationship between most landlords and tenants in the province. Whether you own one basement apartment or a fifty-unit building, the RTA applies to you — and the penalties for getting it wrong range from rent abatements to fines to orders requiring you to pay the tenant's moving costs. This guide covers the practical essentials every Ontario landlord needs to know.
Disclaimer: This guide is for general informational purposes only and is not legal advice. Ontario tenancy law is complex and fact-specific. Consult a qualified legal professional or the Landlord and Tenant Board (LTB) directly for advice specific to your situation.
Overview of the Residential Tenancies Act
The RTA is administered by the Landlord and Tenant Board (LTB), a quasi-judicial tribunal that resolves disputes between landlords and tenants. The legislation applies to most residential rental units in Ontario — including houses, apartments, condominiums, and secondary suites — with a few exceptions: social housing, non-profit housing co-operatives, accommodation where the tenant shares kitchen or bathroom facilities with the owner, and certain transitional housing are not covered.
The core principle of the RTA is rent control combined with secure tenancy. Once a tenant is in place, their rent can only be increased within prescribed annual guidelines (or above-guideline with LTB approval), and their tenancy can only be ended for specific reasons set out in the Act. Landlords cannot simply evict a tenant because they want to or because the tenancy is "month-to-month." The RTA provides significant tenant protections by design, and landlords who treat the Act as optional do so at significant financial and legal risk.
One important caveat: rent control in Ontario as of November 15, 2018, applies only to rental units first occupied for residential purposes before November 15, 2018. Units first occupied for the first time for residential purposes after that date are exempt from rent increase guidelines. This means a purpose-built rental unit completed in 2020 or a basement apartment in a house converted to rental use in 2019 can have rent increased by any amount, without LTB approval, on proper notice.
The Key N-Forms: What They Are and When to Use Them
The LTB uses a standardized set of forms for notices and applications. The "N" series are notices that landlords serve on tenants before filing an application with the LTB. Each form triggers a specific legal process with its own timelines, requirements, and consequences for errors.
N1 — Notice of Rent Increase
Used to give a tenant notice of a rent increase within the annual guideline. Must be given at least 90 days before the proposed increase takes effect. The increase must not exceed the annual rent increase guideline published by the Ontario Ministry of Municipal Affairs and Housing. The 2025 guideline is 2.5%. The N1 must state the current rent, the new rent, and the date the increase is effective. If you fail to give proper notice or exceed the guideline without LTB approval, the increase is void. You cannot retroactively collect guideline increases you failed to properly implement.
N4 — Notice to End a Tenancy Early for Non-Payment of Rent
Served when a tenant is in arrears of rent. The N4 gives the tenant 14 days to pay all outstanding rent (or 7 days if rent is paid weekly or daily). If the tenant pays the full amount owing before the termination date on the notice, the N4 becomes void and the tenancy continues. If the tenant does not pay, the landlord may apply to the LTB using Form L1. Critical: the N4 must state the exact amount owing to the penny. Overstating or understating the arrears amount can invalidate the form. The termination date on the N4 must be calculated correctly from the date of service.
N5 — Notice to End a Tenancy for Interfering with Others, Damage, or Overcrowding
Covers a range of tenant conduct issues: wilful or negligent damage to the unit or building, unreasonably disturbing the enjoyment of other occupants, having more occupants than permitted, and related violations. The N5 is a "cure or quit" notice — the tenant has 7 days to correct the problem. If they do, the notice is void and cannot be used to make an LTB application (for a first N5). A second N5 served within 6 months of a first N5 does not give the tenant an opportunity to cure; the landlord may proceed directly to an L2 application. The N5 must describe the specific incidents with dates.
N8 — Notice to End a Tenancy at the End of the Term
Used when the landlord wants to end the tenancy for reasons such as the tenant's persistent late payment of rent, or the tenancy being purchased by a buyer who required vacant possession (if no N12 applies). The N8 for persistent late payment requires a 60-day notice period terminating at the end of a rental period. The LTB will not automatically grant an eviction on an N8; the landlord must file an L2 application and attend a hearing where the Member considers the totality of the circumstances.
N12 — Notice to End a Tenancy Because the Landlord, a Purchaser, or a Family Member Requires the Unit
The "own-use" eviction notice. Used when the landlord, a member of the landlord's immediate family, or a purchaser of the property genuinely intends to occupy the unit personally. The N12 requires at minimum 60 days' notice terminating on the last day of a rental period, and the stated person must actually intend to move in for at least 12 months. Critically: upon service of an N12, the landlord must pay the tenant compensation equal to one month's rent before the termination date, or offer another acceptable unit. Failure to pay the compensation voids the N12. Bad-faith N12 applications — using own-use eviction to remove a tenant in order to re-rent at a higher rate — are a serious offence. Tenants who are displaced by a bad-faith N12 can file a T5 application; the LTB can order up to 12 months' rent as a penalty plus moving costs and other damages.
The LTB Process: Filing, Hearings, and Enforcement
After serving the appropriate notice and waiting out the notice period, if the tenant has not remedied the situation or vacated voluntarily, the landlord files an application with the LTB. The most common landlord applications are:
- L1 — Application to evict a tenant for nonpayment of rent and collect arrears
- L2 — Application to end a tenancy (used with N5, N8, N12, and other notices)
- L3 — Application to end a tenancy where tenant has given notice but not vacated
- L9 — Application to collect unpaid rent without seeking eviction
Filing fees apply (currently $201 for L1 applications as of 2024). Once an application is filed, the LTB schedules a hearing — currently via phone or video conference for most matters, with in-person available for certain complex cases. Wait times have been a persistent problem at the LTB; as of 2024–2025, non-emergency hearings are often scheduled 3–6 months after filing.
At the hearing, both parties present their evidence and arguments. Members are adjudicators who can consider the circumstances and, in many cases, exercise discretion. For example, on an L1 for arrears, a Member may grant a "pay and stay" order giving the tenant additional time to pay rather than ordering immediate eviction — even over the landlord's objection — if the circumstances warrant it.
If the LTB issues an eviction order and the tenant does not vacate, the landlord must enforce the order through the Court Enforcement Office (Sheriff). Landlords cannot physically remove a tenant themselves, change the locks, or cut services to force a vacancy — these are illegal and constitute an unlawful eviction, exposing the landlord to significant liability.
Above-Guideline Increases (AGI)
In exceptional circumstances, landlords can apply to the LTB for a rent increase above the annual guideline. The AGI process requires the landlord to file an L5 application and demonstrate one of three qualifying grounds:
- Extraordinary increases in operating costs: Unusually large increases in property taxes, heating costs, or water/sewer costs that exceed the guideline's built-in cost assumptions.
- Capital expenditure: Major renovations or replacements that materially improve the property and extend its useful life — such as a new roof, new windows, or a new HVAC system. The eligible capital cost is amortized over a set period (varies by category) and converted into an annual per-unit dollar amount that is added to the guideline increase.
- Security services: New or increased security services that benefit tenants.
The AGI process is time-consuming and document-intensive. Landlords must provide detailed financial records, invoices, and property condition reports. Tenants have the right to participate in AGI hearings and challenge the claimed costs. If granted, an AGI order specifies the maximum additional percentage increase permitted over the guideline, typically over a 3-year amortization period for capital expenditures.
Landlords considering major capital work should consult a property management lawyer before commencing the project to ensure the work qualifies and is documented in a way that supports an AGI application.
Security Deposit Rules: What Ontario Permits
This is one of the most commonly misunderstood areas of Ontario tenancy law: Ontario does not permit security deposits.
Under the RTA, a landlord may only collect:
- A rent deposit (commonly called "last month's rent deposit") equal to no more than one rental period's rent. This deposit can only be applied to the last period of the tenancy — it cannot be held indefinitely as a damage deposit.
- A key deposit in an amount no greater than the actual cost of replacing the key, fob, or access card.
A landlord cannot collect a security deposit, damage deposit, or any other deposit as a condition of renting. Any amount collected in excess of what is permitted under the RTA is illegal and must be returned. Tenants can file a T1 application to have illegal charges returned, plus interest.
The rent deposit must earn interest at the same rate as the annual rent increase guideline, and must be accounted for at the end of the tenancy. When the tenancy ends, the deposit is applied to the last month's rent — the landlord cannot use it to cover cleaning costs or damage. Damage claims must be pursued separately through the LTB's T2/L2 process or Small Claims Court.
Entry Rules: When Can a Landlord Enter?
A landlord's right to enter a tenant's unit is strictly regulated under the RTA. Unauthorized entry violates the tenant's right to quiet enjoyment and is a serious breach — tenants can seek rent abatements for repeated unauthorized entry.
The standard rule is 24 hours' written notice, specifying the reason and the time of entry (between 8 a.m. and 8 p.m.). Permitted reasons include:
- To carry out repairs or maintenance
- To inspect the state of repair
- For a purpose agreed to in writing with the tenant
- To show the unit to prospective tenants (if the tenancy has been terminated or the tenant has given notice)
- To show the unit to prospective buyers (requires 24 hours' notice, must be agreed upon in tenancy agreement or with tenant consent, or after LTB order)
No advance notice is required only in genuine emergencies — fire, flooding, gas leak, or a situation where immediate entry is necessary to protect life or property. Using "emergency" as a pretext for routine inspections is not permitted.
Notice can be waived by the tenant — if a tenant calls and asks you to come fix something today, that constitutes implied consent. Document any tenant-requested entries with a brief note or text message for your records.
Maintenance Obligations
Under section 20 of the RTA, a landlord is responsible for providing and maintaining a residential complex and each rental unit in a good state of repair and fit for habitation, complying with all health, safety, housing, and maintenance standards. This obligation exists regardless of what the lease says and regardless of the age of the building at the time the tenancy began.
Practically, this means landlords must:
- Respond to maintenance requests within a reasonable time (emergency repairs — no heat in winter, water leak — require urgent response)
- Maintain all plumbing, heating, electrical, and structural components in working order
- Ensure the unit meets provincial housing standards (Ontario Property Standards apply in most municipalities)
- Provide adequate heat (minimum 20°C between September 1 and June 15 in most Ontario municipalities)
- Keep common areas clean and safe
Tenants can file a T6 application for maintenance issues. The LTB can order rent abatements retroactively to the date the problem arose, order the landlord to do the repairs, and in egregious cases, allow the tenant to terminate the tenancy. The "I don't have to fix it because it was broken when they moved in" argument does not hold up at the LTB.
2025 Rent Increase Guideline
The Ontario government announced the 2025 rent increase guideline is 2.5%. This is the maximum amount by which a landlord can increase a sitting tenant's rent in 2025 without LTB approval (for units subject to rent control — i.e., first occupied for residential purposes before November 15, 2018).
Key points about the guideline:
- The increase can only be taken once every 12 months
- The 2025 guideline of 2.5% is higher than recent years (2023: 2.5%, 2024: 2.5%)
- An N1 notice must be served at least 90 days before the effective date
- Skipped guideline increases do not accumulate — if you didn't take the 2024 increase, you cannot take 5% in 2025 to catch up
- For exempt units (post-November 15, 2018 first occupancy), there is no statutory cap on rent increases, but the 90-day notice requirement for N1 still applies
Common Mistakes Ontario Landlords Make
Collecting an illegal deposit. Many landlords — particularly new ones from provinces or countries where security deposits are standard — collect a damage deposit at the start of the tenancy. This is illegal in Ontario. Refund it immediately if you realize you've done it.
Signing a fixed-term lease and assuming it prevents eviction difficulty. In Ontario, at the end of a fixed-term tenancy, the tenancy automatically converts to a month-to-month tenancy on the same terms. A tenant who stays past the end date of a one-year lease is not "holding over" unlawfully — they have full RTA protections as a month-to-month tenant.
Serving an N12 without paying compensation. The one-month compensation payment is a hard requirement, not a formality. The LTB will dismiss an N12 application if compensation was not paid before the termination date.
Using a custom lease instead of the Standard Lease. Ontario mandates the use of the Standard Lease Form (Ontario Regulation 9/18) for most residential tenancies. Tenants can demand a standard lease; if the landlord does not provide one within 21 days, the tenant may withhold one month's rent. Any terms in a lease that are inconsistent with or waive RTA rights are void.
Attempting a "cash for keys" without proper documentation. Paying a tenant to vacate is legal and often practical, but the agreement must be properly documented and the tenant must receive independent legal advice (or at minimum be informed of their rights) or the agreement may be set aside by the LTB as unconscionable.
Resources for Ontario Landlords
The Landlord and Tenant Board website publishes all standard forms, the current guideline, and detailed guides for each form. The Residential Tenancies Act, 2006 is available in full on e-Laws. For complex situations — own-use evictions, AGI applications, large arrears files — retain a paralegal or lawyer who specializes in residential tenancy law; the cost is almost always less than the cost of a procedural error that derails an LTB application.
