Landlord Duty to Mitigate Eviction Losses in Ontario

Tenants in Ontario who face eviction may wonder what duties their landlord has after a notice or application is issued. One important obligation is that landlords must try to reduce or “mitigate” financial losses caused by a tenant leaving early or being evicted. This guide explains, in plain language, what mitigation means for renters, what actions a landlord is expected to take, and how tenants can document attempts to re-rent a unit or reduce damages. You will find practical steps to protect your rights, the official forms and tribunal contacts to use, and examples of common scenarios like unpaid rent or illegal entry. The goal is to help renters respond confidently and access the correct resources in Ontario.

What mitigation means for renters in Ontario

Mitigation means a landlord must take reasonable steps to reduce financial loss when a tenancy ends early, for example by actively trying to re-rent the unit. Landlords cannot simply leave a unit vacant and claim all lost rent without showing they tried to find a replacement tenant. The Residential Tenancies Act, 2006 sets the legal framework for these duties and what tenants and landlords can expect.^[2]

Common landlord actions that show mitigation

• Advertise the unit promptly and fairly to reach potential renters.
• Document showings, inquiries and applications to prove active efforts.
• Offer reasonable rent or flexible terms when market conditions require it.
• Allow reasonable access for viewings while respecting tenant privacy and notice rules.
• Keep records of contacts, ads, screening results and any refusals.

What tenants should do to protect themselves

If you are a tenant facing eviction or early termination, take practical, clear steps to protect your position:

• Keep copies of all notices, emails and messages about the tenancy and any payments.
• Save rent receipts, bank records or screenshots showing payments or arrears discussions.
• Ask the landlord in writing for details of their re-rental efforts if they claim losses.
• Attend any tribunal hearings and bring your records and witnesses if asked.

Official forms and when to use them

Landlords and tenants use specific forms when there is an eviction or dispute. Common documents include the landlord notice and tribunal applications; for example, landlords often start with a notice such as an N4 (notice to end tenancy for non-payment) and then file an L1 application to the Landlord and Tenant Board if the issue is not resolved. The official Landlord and Tenant Board forms list explains form names and use and shows how to file applications.^[1]

How the tribunal evaluates mitigation

The Landlord and Tenant Board will look at whether the landlord acted reasonably and in a timely way to reduce losses. That includes whether the landlord:

• Placed ads and showed the unit within a reasonable time.
• Took reasonable steps on rent level or lease terms to attract tenants.
• Kept records proving the above and considered suitable applicants.

Example scenarios

If a tenant leaves owing rent and the landlord advertises the unit the same week, screens applicants, and re-rents at a similar rate, the landlord may only recover the short gap of rent between tenancies. If the landlord does not advertise or refuses reasonable applicants, the board may reduce or deny claimed losses.
