Duty to Mitigate: Ontario Eviction Damage Cases

Tenants facing eviction-related damage claims in Ontario often worry about responsibility for repairs, lost rent, or compensation. The duty to mitigate means both landlords and tenants must take reasonable steps to reduce losses after a breach, like finding a new tenant or documenting condition. This plain-language guide explains how the duty to mitigate works under Ontario rules, what tenants should do when notified of damage claims, which official forms and Tribunal contacts to use, and how to present evidence to limit liability. You’ll get practical action steps, timelines, and examples designed for renters who want to protect their rights while cooperating with the legal process.

What the duty to mitigate means

In Ontario the duty to mitigate requires reasonable efforts to reduce loss after a tenancy ends or when a landlord claims damages; it applies in eviction and damage cases handled by the Landlord and Tenant Board Landlord and Tenant Board^[1] and sits alongside the Residential Tenancies Act, 2006 Residential Tenancies Act, 2006^[2]. For tenants this usually means documenting the unit, responding to notices, and looking for replacement housing so a landlord can reasonably re-rent the unit.

How this applies to eviction and damage cases in Ontario

When a landlord claims damages after an eviction or tenancy breach, the Tribunal will consider whether both sides took reasonable steps to limit losses. Landlords should advertise and try to re-rent, and tenants should avoid unnecessary destruction, allow reasonable access for showings or repairs, and keep records. Landlords have procedures and forms for claims; you can review guidance and forms on the LTB site LTB forms and guides^[3]. For practical guidance on how landlords handle end-of-tenancy matters, see How Landlords Should Handle End of Tenancy Issues Properly and Legally.

Filing forms and timelines

Landlords normally start a claim at the LTB using their application forms and may claim unpaid rent, repairs or other compensation; tenants should check the specific form and timeline on the LTB forms page LTB forms and guides^[3]. Examples: Form L1 (Application to the LTB to end a tenancy and evict for non-payment or other grounds) is used when a landlord seeks to end the tenancy; a tenant can file the required written response and present mitigation evidence at the hearing. Always follow the instructions on the notice for how and when to file your response so you don't lose the chance to be heard.
