When Disputes Arise About Sublets, Assignments, or Unauthorized Occupants
Ontario’s tenancy rules strictly regulate when a rental unit may be sublet or assigned, and when a landlord may take action against an unauthorized occupant or subtenant. These situations are governed by specific provisions of the Residential Tenancies Act, 2006, and disputes are addressed through an A2 Application before the Landlord and Tenant Board.
An A2 Application is not a general eviction or enforcement tool. It is available only in defined circumstances and is subject to strict limitation periods. Filing the wrong application or missing a deadline can prevent relief entirely.
We assist landlords throughout Ontario in assessing whether an A2 application is available and, where appropriate, preparing and advancing these applications in compliance with the Board’s requirements.
What Is an A2 Application?
An A2 Application may be brought by either a landlord or a tenant, but for very different reasons.
In general terms, an A2 application is used to address disputes involving:
- Unauthorized occupants or subtenants
- Subtenants who fail to vacate after the end of a subtenancy
- Disputes about consent to assign a tenancy in limited circumstances
An A2 application cannot be used simply because a landlord does not wish to consent to an assignment. The Act draws a critical distinction between refusing consent in principle and refusing consent unreasonably after consent is required.

Landlord A2 Applications
Unauthorized Occupants or Subtenants
A landlord may file an A2 application where:
- A tenant transferred occupancy of the rental unit without the landlord’s consent, and
- Another person is occupying the unit as an unauthorized occupant or subtenant
In these cases, a landlord may seek:
- Termination of the tenancy
- Eviction of the unauthorized occupant or subtenant
- Compensation for the period of unauthorized occupancy
These applications must be filed within 60 days after the landlord discovers the unauthorized occupancy. Missing this deadline can bar relief.
Subtenant Fails to Vacate at the End of a Subtenancy
A landlord may also file an A2 application where:
- A lawful subtenancy has ended, and
- The subtenant fails to vacate the rental unit
In these circumstances, the landlord may seek eviction of the subtenant and compensation for the period they remained in the unit after the subtenancy ended. Again, strict timelines apply, and proper documentation of the subtenancy and its end date is essential.
What the Board Will Examine
When deciding an A2 application, the Board will typically examine:
- Whether consent was required under the Act
- Whether consent was requested properly
- Whether any refusal or conditions were reasonable
- Whether statutory timelines were met
- The nature of the occupancy arrangement
- The evidence provided by the parties
These applications are highly fact-specific and often turn on written communications, timelines, and credibility.
Compensation and Monetary Claims
Depending on the circumstances, an A2 application may include claims for:
- Daily compensation equal to the rent for unauthorized occupancy
- Compensation for a subtenant remaining after the end of a subtenancy
Any monetary claims must comply with statutory limits and be supported by proper calculations and evidence.
Why A2 Applications Require Careful Assessment
A2 applications are frequently dismissed due to:
- Filing outside the applicable limitation period
- Using A2 where a different application is required
- Misunderstanding consent rules
- Inadequate evidence of unauthorized occupancy
- Procedural errors
Because A2s are technical and deadline-driven, early legal review is critical.
