Ontario Residential Tenancy Law: RTA, LTB, Evictions, and Rent Increases

March 2026 · 15 min read

Ontario residential tenancy law is governed by the Residential Tenancies Act, 2006, SO 2006, c 17 (RTA). The Act covers virtually all residential rental units in Ontario and is administered by the Landlord and Tenant Board (LTB). Understanding the RTA framework — rent control, eviction grounds, N-forms, and LTB procedure — is essential for lawyers advising landlords and tenants in Ontario's highly contested rental market.

1. Scope and Coverage

The RTA applies to most residential rental units in Ontario. Key exemptions where the RTA does not apply:

• Units rented by non-profit housing co-operatives
• Units in buildings where the owner lives and shares a kitchen or bathroom
• Vacation or tourist accommodations used for less than 14 consecutive days
• University and college student residences
• Commercial units

New residential units first occupied for residential purposes after November 15, 2018 are exempt from rent control under the 2018 amendments. All units rented on or before that date remain subject to the annual rent increase guideline.

2. Rent Control and Rent Increases

For rent-controlled units (first occupied on or before November 15, 2018), a landlord may only increase rent once in a 12-month period and only by the amount permitted by the annual Rent Increase Guideline published by the Ontario government each year. The guideline is typically tied to the Ontario Consumer Price Index.

A landlord wishing to increase rent must give 90 days written notice of the increase using Form N1. Notices shorter than 90 days are invalid.

Above-guideline increases (AGIs) are available in limited circumstances:

• Extraordinary increases in operating costs (municipal taxes, hydro, natural gas)
• Capital expenditures — eligible capital work completed that benefits the tenants
• Security service costs

An AGI application is filed with the LTB. Tenants receive notice and may dispute the application. AGI hearings can be lengthy and complex — expert evidence on the cost calculations is frequently required.

3. Eviction Grounds and N-Forms

Eviction of a tenant requires a valid ground under the RTA and a Notice to Terminate served using the appropriate N-form. There is no "no-fault" eviction in Ontario except in specific statutory circumstances.

3.1 Own Use Evictions — N12

An N12 notice is served where the landlord, a family member, or a purchaser requires the unit for their own occupation. Requirements:

• The landlord must intend in good faith to use the unit as a principal residence for at least one year
• One month's compensation must be paid to the tenant (or substitute equivalent rent-free month)
• For purchaser's own use: the sale agreement must require vacant possession and the purchaser must file an affidavit of good faith intention

Where the landlord fails to use the unit as required — or re-rents within one year to another tenant at a higher rent — the evicted tenant may apply to the LTB for remedies including reinstatement or up to 12 months' rent as a penalty (s. 57).

3.2 Demolition and Renoviction — N13

"Renovictions" — evictions for major renovations requiring vacant possession — have been significantly tightened. The landlord must:

• Obtain all necessary building permits before the N13 takes effect
• Offer the tenant the right of first refusal to re-occupy the unit after renovations at no more than the lawful rent that was charged before eviction
• Pay the tenant 3 months' rent as compensation

The LTB will scrutinize whether the work genuinely required vacant possession and whether the permits are in order. Applications filed without proper permits are typically dismissed.

4. LTB Applications and Procedure

4.1 Filing an Application

After serving the appropriate N-form and waiting the required notice period (or where the tenant has not vacated voluntarily), the landlord files an Application to Evict with the LTB. The main applications are:

• L1: Application to evict for non-payment of rent and collect rent owed
• L2: Application to evict for reasons other than non-payment (behaviour, own use, demolition)
• L3: Application to collect rent the tenant agreed to pay after termination
• L4: Application to evict following a mediated/conditional order

Tenants may file their own applications:

• T1: Application for a rent rebate (rent paid above the lawful rent)
• T2: Application about landlord rights and obligations (illegal entry, harassment, interference with reasonable enjoyment)
• T3: Application to reduce rent or services
• T5: Application where landlord gave notice of termination in bad faith
• T6: Application about maintenance and repair

4.2 LTB Hearings

LTB hearings are conducted in-person, by telephone, or by videoconference. Since the pandemic, most LTB hearings are conducted by videoconference through a "hearing block" system — multiple applications are scheduled in the same hearing block, with the adjudicator hearing cases sequentially.

The LTB applies rules of natural justice but is not bound by the strict rules of evidence. Documents may be admitted without formal authentication. However, best practices include:

• Preparing a disclosure package in advance and providing to the other party
• Organizing rent ledgers and payment records clearly
• Preparing witness evidence in advance (especially for factual disputes about N5/N7 grounds)
• Filing a Tenant Duty Counsel consultation form in advance if the tenant is unrepresented

4.3 Section 83 Relief from Eviction

Even where a landlord proves the grounds for eviction, s. 83 requires the LTB to consider whether it would be unfair to grant the eviction order — having regard to all the circumstances. The LTB may:

• Delay the eviction to a future date to give the tenant time to find housing
• Make a conditional order (e.g., the eviction is stayed provided the tenant pays outstanding rent by a deadline)
• Refuse the eviction order entirely in exceptional circumstances

Section 83 relief is mandatory consideration for all eviction grounds except those involving impaired safety or illegal acts — where s. 83 provides the LTB with discretion but no mandatory obligation to consider relief.

5. Tenant Rights and Landlord Obligations

5.1 Maintenance and Repair

Landlords must maintain rental units in a good state of repair and fit for habitation, complying with all applicable health, safety, housing, and maintenance standards (s. 20). This duty cannot be contracted out of — any provision in a lease purporting to make the tenant responsible for major maintenance is void.

A tenant who files a T6 maintenance application may obtain a rent abatement proportional to the interference with enjoyment of the unit. Severe maintenance failures — mold, pest infestations, lack of heat — have resulted in abatements of 20-40% of rent for the period of the failure.

5.2 Entry by Landlord

A landlord may enter a rental unit only in limited circumstances (s. 27):

• In emergency
• After giving 24 hours' written notice with time of entry between 8 AM and 8 PM and a reason for entry
• By agreement
• After giving notice in the case of showing units to prospective tenants or purchasers

Unauthorized entry — including entry without 24-hour notice or outside permitted hours — can result in a T2 application and an order for rent abatement or a fine against the landlord.

6. Enforcement of LTB Orders

An LTB eviction order authorizes the Sheriff (now the Court Enforcement Office) to enforce the eviction. The landlord must file the order with the Court Enforcement Office and pay the filing fee. The Sheriff will attend on a scheduled date to remove the tenant if they have not vacated voluntarily.

A landlord may not self-help evict — changing locks, removing doors, or physically removing a tenant without a Sheriff enforcement is an illegal eviction under s. 31 and exposes the landlord to significant damages.

Monetary orders from the LTB (for rent arrears or tenant applications for rebates) may be enforced in the Small Claims Court or the Superior Court if the amount exceeds Small Claims Court jurisdiction.

7. Practical Tips for Landlord and Tenant Counsel

• Get the N-form right the first time: Errors in N-forms — wrong dates, wrong amounts, wrong statutory grounds — typically require re-starting the notice process. Verify the correct form, correct rent amount, and correct calculation of the notice period before serving.
• For N4 (non-payment): verify the exact arrears: The N4 must state the correct amount owing. Over-stated amounts can result in the Board voiding the notice. The tenant's right to void the N4 by paying within 14 days makes accuracy critical.
• For N12 own-use: prepare the affidavit in advance: The purchaser's affidavit of intention must be filed with the L2 application. Courts have set aside N12 orders where the affidavit was insufficient or the good faith intention was questionable.
• Offer section 83 evidence proactively: For tenant counsel, file evidence of hardship, housing search efforts, dependency of children, and any disability in advance. For landlord counsel, consider what s. 83 factors apply and address them in submissions.
• Track the one-year own-use obligation: After an N12 eviction, the landlord must occupy for at least one year. Advise landlord clients of this obligation explicitly and in writing.

Conclusion

Ontario residential tenancy law is highly protective of tenants and procedurally demanding for landlords. The N-form system, notice periods, and LTB procedure must be followed exactly — procedural errors typically restart the clock. Lawyers advising in this space must be familiar not only with the statutory grounds but with the LTB's adjudicative practices, which have become increasingly nuanced as the rental market has intensified.
