Most tenants in Ontario know that the Landlord and Tenant Board is the primary forum for resolving disputes with a landlord. What far fewer tenants realize is that certain claims against a landlord can and should be pursued through Ontario Small Claims Court rather than the Board. Understanding which forum applies to which type of claim is not just a procedural question. Filing in the wrong venue can result in delays, dismissal, and wasted time that could have been avoided entirely.

The short answer is yes, a tenant can sue a landlord in Small Claims Court in Ontario, but only where the specific matter falls outside the exclusive jurisdiction of the Landlord and Tenant Board. Knowing where that line is drawn is the key to making the right decision before any documents are filed.

When the Landlord and Tenant Board Has Exclusive Jurisdiction

The Landlord and Tenant Board operates under the Residential Tenancies Act, 2006 and has exclusive jurisdiction over most disputes arising directly from the landlord and tenant relationship while the tenancy is active. This includes applications for rent reductions, maintenance and repair failures, illegal rent increases, harassment by a landlord, and unlawful entry into a rental unit. For matters of this nature that occur during an ongoing tenancy, the LTB is the correct and mandatory forum.

Attempting to bring an active tenancy dispute to Small Claims Court when the LTB has exclusive jurisdiction over it is a jurisdictional error that can result in the claim being dismissed without a hearing on the merits. This is one of the most important reasons to seek qualified legal advice before deciding where to file. The distinction between what the LTB handles and what falls to Small Claims Court is not always obvious, and getting it wrong costs both time and money.

When Small Claims Court Is the Right Forum

There are specific circumstances in which Small Claims Court is the appropriate forum for a tenant’s claim against a landlord. One of the most common arises after a tenancy has ended. Under section 87(1) of the Residential Tenancies Act, 2006, the LTB generally loses jurisdiction over monetary claims between landlords and tenants once the tenant has vacated the rental unit. At that point, claims for unreturned deposits, unpaid compensation, or other monetary amounts owed by the landlord may be pursued through Small Claims Court up to the current $50,000 jurisdictional limit.

Small Claims Court is also the appropriate venue for claims that fall entirely outside the scope of the Residential Tenancies Act, such as disputes arising from a breach of contract that is not directly governed by the RTA, or tort claims involving negligence or property damage caused by a landlord’s conduct. MTS Paralegal Services P.C. has previously addressed the distinction between these two forums in detail at mtsparalegalservices.com, and that resource is worth reviewing before making any filing decisions.

Common Tenant Claims Against Landlords in Small Claims Court

Several types of monetary claims from tenants against former landlords are regularly brought before Ontario Small Claims Court. Unreturned last month’s rent deposits are among the most frequent. Where a landlord fails to return or properly apply a last month’s rent deposit after a tenancy ends, and the matter cannot be addressed through the LTB due to jurisdiction or timing, Small Claims Court provides an accessible path to recovery.

Claims for damages caused by a landlord’s negligence, such as property damage resulting from a landlord’s failure to maintain the building in a good state of repair, may also be pursued in Small Claims Court where the facts support a claim in negligence or breach of contract rather than a breach of the Residential Tenancies Act. Enforcement of existing LTB orders that a landlord has failed to comply with can also involve Small Claims Court enforcement mechanisms, including garnishment of the landlord’s bank account or wages.

What Evidence a Tenant Needs to Build a Strong Claim

As with any Small Claims Court matter, the quality and organization of the evidence presented determines the strength of the case. A tenant pursuing a claim against a former landlord should gather every relevant document before filing, including the lease agreement, rent payment records, any written communications with the landlord, move-in and move-out inspection reports, receipts for any deposits paid, photographs of the rental unit, and any prior LTB orders or decisions related to the tenancy.

A demand letter sent to the landlord before filing a claim is strongly advisable in every case. It demonstrates that reasonable steps were taken to resolve the matter without litigation, establishes a clear record of the amount being claimed and the basis for the claim, and creates additional documentary evidence that supports the tenant’s position. The two-year limitation period under the Limitations Act, 2002 applies to Small Claims Court claims, meaning the matter must generally be filed within two years of when the tenant knew or ought to have known the claim arose.
