Ontario Court of Appeal: Landlord’s Estate Cannot Pursue N12 Own-Use Eviction After Death

On 16 July 2026 the Court of Appeal for Ontario released Miller Estate v. Arguelles, 2026 ONCA 518. The decision clarifies two important points about “landlord’s own use” (N12) evictions under the Residential Tenancies Act, 2006 (RTA).

First, only an individual can rely on the own-use ground in section 48. An estate is not an “individual,” so an N12 served by a landlord who later dies cannot be continued by the estate for the same purpose. Second, the mandatory requirement in section 71.1 to disclose every prior N12 notice on the eviction application is substantive; the Landlord and Tenant Board cannot cure a missing disclosure by amendment at the hearing.

These holdings have immediate practical consequences for tenants facing N12 applications and for landlords or estate trustees who wish to recover possession for personal or family use.

Brief facts

The tenant had lived in the unit since 2017. The landlord (Ms. M) and her son served an N12 in March 2022 stating the unit was required for Ms. M’s child. A second N12 was served in June 2022. The son filed the L2 application based on the June notice but did not disclose the earlier March notice. Ms. M died in December 2022, before the hearing. The Board substituted the Estate as applicant, allowed the missing disclosure to be added, and ordered eviction. The Divisional Court upheld the order. The tenant appealed.

Key holdings

The Court of Appeal allowed the appeal and quashed the application as a nullity.

1. Standing under s. 48 – Subsections 48(1) and (5) require that an individual landlord (or certain close relatives) intends to occupy the unit. The criteria must exist at the time of termination, not merely when the notice is served. Because Ms. M had died, neither her son nor the Estate met the statutory definition of an individual who could occupy or whose child could occupy. The Estate therefore lacked standing to pursue the own-use claim.

1. Mandatory disclosure under s. 71.1 – An applicant must disclose every N12 notice previously given to the tenant in respect of the same rental unit. Failure to do so is a fatal defect that the Board cannot remedy by amendment. The omission rendered the application invalid from the outset.

What this means for tenants

If you receive an N12 and the named landlord later dies, or if the L2 application fails to list every earlier N12, you may have a strong ground to argue the application is invalid. The Court emphasized that administrative efficiency at the LTB cannot override the clear statutory requirements or the remedial purpose of the RTA. Tenants should keep copies of every notice they receive and raise these points early, ideally with legal advice or at the hearing.

What this means for landlords and estate trustees

• Serve N12s carefully and ensure the intended occupant still qualifies under s. 48 at the moment the tenancy is to end.
• On every L2 application, disclose all prior N12s for that unit. Omitting one is not a technicality the Board can fix.
• If the original landlord dies, the estate generally cannot continue an own-use claim based on the deceased’s intention. Other grounds (for example, purchaser’s own use under s. 49, or non-payment) may still be available, but the pure “own use” route under s. 48 will usually fail.

Practical next steps

1. Review any outstanding N12 or L2 for completeness of disclosure and the current status of the named landlord.
2. Confirm the intended occupant still meets the statutory relationship tests.
3. If you are a tenant and believe the application is defective, file a response or raise the issue at the earliest opportunity.
4. Estate trustees should obtain independent advice before filing or continuing an own-use application.
