Ontario Landlord and Tenant Board (LTB) handles residential landlord-tenant disputes under Canadian law. Both landlords and tenants may file applications here — landlords typically seek eviction or rent repayment, while tenants seek return of security deposits, enforcement of habitability obligations, or protection from unlawful actions. Common disputes include rent arrears and eviction applications (L1/T1), above-guideline rent increase disputes, illegal eviction and lockout complaints, maintenance and repair applications, and last month's rent deposit disputes. Ontario limits annual rent increases, making disputes about unauthorized rent increases a significant category of applications. Ontario prohibits security deposits entirely — only a last month's rent deposit is allowed. Rent increases for most units are subject to the annual rent increase guideline. The LTB handles all residential tenancy disputes and has experienced significant backlogs — hearing wait times can be several months. ThreadLock helps both landlords and tenants build a documented, chronological record of communications, incidents, and property condition — the kind of organized evidence that resolves these disputes faster.
Both individual landlords and business entities (corporations, property management companies) may file with the tribunal. Tenants may also file applications to enforce their rights, recover deposits, or challenge improper actions. Note: Ontario prohibits security deposits — only a last month's rent deposit is permitted by law. You must file with the tribunal that has jurisdiction over the property location. If you are the tenant, you may also contact a tenant rights organization or legal aid office in Ontario before filing to understand your options. Fee waivers may be available for low-income filers — ask the tribunal clerk or office.
Pre-filing notice requirement: 14 days for nonpayment (N4 Notice); 20 days for substantial interference. This notice must be properly served — typically by hand delivery, certified mail, or posting on the door — and the notice period must fully expire before you file with the tribunal. Failure to give proper notice is a common reason cases are dismissed.
To begin a dispute in Ontario, file an application with the Ontario Landlord and Tenant Board (LTB). The filing fee is $186 (L1 — rent arrears and eviction); $57 (L2 — eviction for other reasons). If you are a tenant filing against a landlord (for deposit return, habitability, or unlawful entry), the process is similar — complete the appropriate form and pay the applicable fee.
The tribunal will review the application, notify the other party, and schedule a hearing or mediation session. Many Canadian residential tenancy tribunals conduct hearings by phone or video. Bring all relevant documents — lease, rent receipts, communications, photos — to the hearing.
The tribunal can issue a variety of orders: payment of rent arrears, return of a security deposit, possession of the rental unit, or compensation for damages. Tribunal orders are legally enforceable. Security deposits: Ontario prohibits security deposits — no deposit return deadline applies.
Landlord-tenant disputes are won or lost on documentation. The Ontario Landlord and Tenant Board (LTB) expects organized, chronological evidence — not narrative arguments. Whatever the dispute type, the starting point is always the same: the lease agreement, the rental payment history, and the written communications between landlord and tenant.
For Ontario disputes involving rent arrears and eviction applications (L1/T1), above-guideline rent increase disputes, illegal eviction and lockout complaints, maintenance and repair applications, and last month's rent deposit disputes, the evidence that most often determines outcomes includes: dated photographs of property condition at move-in and move-out, text message and email records showing what was communicated and when, maintenance request logs showing when issues were reported and whether they were addressed, and copies of all notices with proof of service. Courts and tribunals cannot award what you cannot prove — bring every document that supports your position.
ThreadLock's incident journal is designed exactly for this purpose: log events as they happen with date, time, and attached photos or documents. If a landlord fails to make a repair, document it the day you notice it. If a tenant misses rent, document every communication about it. The timeline builder assembles those records into a chronological view of the tenancy, and the exhibit export tool produces a labeled PDF packet ready to hand to a judge, tribunal officer, or opposing party at the hearing.
How much notice does a landlord need to give before evicting a tenant in Ontario?
The required notice depends on the reason. For nonpayment of rent: 14 days for nonpayment (N4 Notice); 20 days for substantial interference. A landlord who files without giving proper notice first may have the case dismissed. The notice must be properly served — not just sent — and the full notice period must expire before filing.
Can a landlord charge a security deposit in Ontario?
No. Ontario prohibits security deposits. last month's rent only A landlord who collects an unauthorized deposit may be required to return it with interest.
What happens if a tenant does not leave after receiving a notice to quit?
If the tenant does not vacate or remedy the issue within the notice period, the landlord may file an eviction application with the Ontario Landlord and Tenant Board (LTB). If the tribunal grants possession, the landlord receives a writ that allows law enforcement to remove the tenant if they still do not leave voluntarily. A landlord may not change locks, remove belongings, or shut off utilities to force a tenant out — that is an illegal lockout regardless of the circumstances.
What can a tenant do if the landlord fails to make necessary repairs?
Tenants in Ontario have the right to a habitable rental unit. If a landlord fails to make repairs after being notified in writing, a tenant may be able to file a complaint with the Ontario Landlord and Tenant Board (LTB), withhold rent (in some jurisdictions), or pursue other remedies under Ontario law. Document every repair request in writing with the date sent — this record is essential if the matter goes to tribunal.
Are there limits on how much a landlord can raise rent in Ontario?
Yes. Ontario limits annual rent increases. Landlords must follow the required notice periods and stay within the applicable guideline or cap. Tenants who receive an above-guideline increase notice may challenge it through the tribunal within the applicable time limit.
