If my rental unit is condemned or becomes impossible to live in due to an unforeseeable event, does the doctrine of frustration end my tenancy in Ontario, and what should I do next?
Gutoski Legal Services can help you understand when the doctrine of frustration applies to a residential tenancy in Ontario, such as after a fire, flood, or municipality condemnation that makes the unit impossible to occupy, and what recourse you may have as a tenant (including how this affects security of tenure) under section 19 of the Residential Tenancies Act, 2006, and related LTB tribunal reasoning like Residential Tenancies Act, 2006, S.O. 2006, Chapter 17, section 19 If your unit cannot be physically lived in because it is officially prohibited or uninhabitable for an unknown or lengthy time, the tenancy may be deemed frustrated and end by operation of law, so you should document conditions, get the condemnation/repair timelines in writing, ask for any required notices, and discuss practical next steps promptly with a paralegal who can review your situation and prepare tenant-protective instructions for your circumstances with Gutoski Legal Services at (289) 902-0227.

Understanding When the Doctrine of Frustration Applies to a Residential Tenancy and What Recourse Does a Tenant Have?
Certain events, such as a major fire, flood or serious water damage, tornado or windstorm, or some other unforeseen circumstances, including changes in law, may arise with the result being that occupancy of the residential premises becomes impossible. When the tenancy becomes impossible due to an unforeseeable outside force, sometimes called a force majeure event, the contractual obligations of both the landlord and the tenant, whether during a lease period or after the tenure converts to a month-to-month, are deemed frustrated and the tenancy arrangements come to an end as per section 19 of the Residential Tenancies Act, 2006, S.O. 2006, Chapter 17 where it is said:

19 The doctrine of frustration of contract and the Frustrated Contracts Act apply with respect to tenancy agreements.
Condemnation
Sometimes a rental unit becomes unoccupiable due to an order issued by the local municipality that condemns the premises. This type of situation occurred and was the issue within the case of AS v. CJM, TSL-05808-10 (Re), 2010 CanLII 58985 where it was said:
1. At the hearing before me the parties filed an order dated September 27, 2010 issued by the City of Toronto that says the residential complex is unsafe and that occupancy of the rental unit is prohibited.
2. As I explained at the hearing section 19 of the Residential Tenancies Act, 2006 (the ‘Act’) says: “The doctrine of frustration of contract and the Frustrated Contracts Act apply with respect to tenancy agreements.” Essentially the doctrine of frustration says that when a contract becomes impossible of performance, then the contract has come to an end. As the doctrine applies to residential tenancy agreements what this means is that when a residential complex cannot be physically lived in anymore because it has been condemned, the tenancy has come to an end by operation of law.
3. As a result, an order will issue declaring the tenancy termination by operation of the doctrine of frustration.
Accordingly, and apparently, despite that premises may become condemned due to the neglect of the landlord, as a matter of law, frustration of the tenancy agreement, and thereby termination of the tenancy agreement with corresponding termination of the tenancy, results when the premises are officially condemned.
Ceasing of Security of Tenure
Where a tenancy agreement is deemed frustrated, such as in circumstances where a fire requires restorative work that will be extensive and take considerable time, the security of tenure, including first right of refusal to return following restorative work, is absent. Only where the restorative work can be done in a reasonable amount of time will the tenancy agreement be without frustration and therefore with security of tenure protected as per the case of Y.Y. v. A.T. and L.W., TEL-32649-12 (Re), 2013 CanLII 51226 where it was said:
1. The Residential Tenancies Act, 2006 did apply to this unit from June 1, 2012 until December 1, 2012. At that time the unit was deemed uninhabitable and the tenancy agreement became frustrated pursuant to the Frustrated Contracts Act and as permitted under section 19 of the Residential Tenancies Act, 2006 (RTA).
2. As a result of the lengthy period of time required to make repairs to the unit there is no foreseeable date that the Tenants would be permitted back into the rental unit. There is no requirement under the RTA for the Landlord to offer the Tenants first right of refusal when the unit does become habitable.
3. Based on the evidence provided and the fact this vacancy of the rental unit is not for a short period of time I have deemed the rental contract to be frustrated as of December 1, 2012.
Summary Comment
When a serious force majeure event occurs, rendering the premises unoccupiable for an unforeseeable length of time, the tenancy agreement, whether within a lease period or month-to-month period, becomes frustrated and all obligations cease including the security of tenure usually enjoyed by the tenant.
