When It Is Unclear Whether the Residential Tenancies Act Applies
In some situations, it is not clear whether a rental unit or residential complex is governed by the Residential Tenancies Act, 2006 (RTA). This threshold issue can determine whether the Landlord and Tenant Board has jurisdiction over a dispute at all.
An A1 Application allows a landlord or tenant to ask the Board to determine whether all or part of the RTA applies to a particular rental unit or residential complex. These applications are technical and fact-specific, and the outcome often affects whether other applications can proceed.
We assist landlords throughout Ontario in assessing whether an A1 application is appropriate and in preparing and presenting these applications before the Board.
What Is an A1 Application?
An A1 Application is used to obtain a determination from the Board on whether the RTA applies to a rental unit or residential complex, or whether only certain provisions of the Act apply.
An A1 application may determine:
- Whether the tenancy is governed by the RTA
- Whether the Board has jurisdiction to hear related applications
- Whether other landlord or tenant applications may proceed
An A1 application does not determine eviction, rent arrears, or damages. Its purpose is jurisdictional.

Common Situations Where an A1 Application Arises
Landlords may need to consider an A1 application in situations such as:
- Disputes about whether a unit is exempt from the RTA
- Shared accommodation arrangements where the applicability of the Act is unclear
- Questions about whether a unit is residential in nature
- Situations where only part of the RTA may apply
- Jurisdictional objections raised in response to other applications
Because jurisdictional issues can arise unexpectedly, A1 applications are often closely connected to other proceedings.
What the Board Will Examine
When deciding an A1 application, the Board typically examines:
- The nature and use of the rental unit or complex
- The facts surrounding the occupancy arrangement
- Whether any statutory exemptions apply
- Whether all or part of the RTA governs the tenancy
- The evidence provided by both parties
The Board’s focus is on legal characterization rather than fairness, making careful presentation of facts and documentation essential.
Relationship to Other LTB Applications
An A1 application is often brought before or alongside other applications. In some cases, resolving the A1 issue first is necessary to determine whether the Board can proceed with related matters.
How and when an A1 application is filed — and how it is coordinated with other proceedings — can have significant procedural consequences.
How We Assist with A1 Applications
We assist landlords with:
- Assessing whether an A1 application is appropriate
- Identifying jurisdictional risks and implications
- Preparing the A1 application and supporting materials
- Coordinating A1 proceedings with related LTB matters

Early assessment can help prevent wasted time, dismissed applications, or unintended jurisdictional consequences.
