Repairing Units After Flood or Water Damage in Ontario

Maintenance & Repairs Ontario 4 min read · published March 09, 2026 Flag of Ontario

Flood or water damage can leave renters overwhelmed. If you rent in Ontario, you have practical rights and steps to follow to keep yourself safe and protect your legal position. Start by ensuring everyone is safe, report the issue to your landlord in writing, and document damage with photos and notes. Landlords are generally responsible for restoring basic habitability, but repairs, timelines, and temporary relocation options depend on the lease and the Residential Tenancies Act. This article explains what to do immediately, how to request repairs, which official forms and tribunal to use, how to document losses, and when to seek help. Clear records and timely action give tenants the best chance of a fair repair outcome.

What to do immediately after flood or water damage

First, ensure personal safety and turn off electricity if there is any risk. If the water source is obvious and safe to stop, do so, then contact your landlord immediately and follow up in writing so there is a clear record of the request for repairs. Include the date, time, location of damage and a short description of the visible harm. If immediate hazards exist, call emergency services.

Document every step with photos and dated notes.

When you contact your landlord, be specific about the repairs you need and request a timeline. If the landlord does not respond or refuses necessary repairs, you may be able to file an application with the Landlord and Tenant Board for an order to require repairs or rent abatement[1].

Landlord responsibilities and timelines

Under Ontario rules the Residential Tenancies Act sets basic habitability obligations that generally require landlords to keep rental units in a good state of repair and fit for habitation. What counts as "reasonable time" depends on the severity of damage: emergencies and vital services require immediate action while non-urgent repairs have longer timelines. If you and your landlord cannot agree on timing, the Landlord and Tenant Board can be asked to decide and issue orders based on the evidence and the law[2].

Respond to legal notices within deadlines to avoid losing rights.

Documenting damage and saving evidence

Good documentation makes a strong case. Keep dated records of communications, photos, and receipts for expenses related to temporary fixes or relocation.

  • Take clear photos and videos from multiple angles and note the date and time.
  • Keep a dated written log of events, conversations, and when services arrived.
  • Keep receipts for temporary accommodation, cleaning, or emergency services and note why they were necessary.
  • Send written notice to your landlord describing the damage and keep a copy for your records.
Detailed documentation increases your chances of success in disputes.

Temporary repairs, relocation and payment issues

If immediate temporary repairs are needed to prevent further damage, the landlord should arrange or approve them. If the landlord refuses and the situation is urgent, arrange emergency repairs and keep all receipts; you may be able to seek reimbursement. If the unit is uninhabitable, discuss temporary relocation and who pays for reasonable costs.

If you pay for emergency repairs or temporary housing, keep detailed receipts and written explanations of why the expenses were necessary. In disputes, the Board will consider the reasonableness of costs and whether the tenant gave the landlord an opportunity to act.

When to file with the Landlord and Tenant Board

If the landlord does not make timely repairs you can file an application with the Landlord and Tenant Board for an order to fix the problem or for rent abatement. The Board handles residential tenancy disputes in Ontario and accepts applications and evidence online and by mail[3]. You should include copies of your written notices, photos, receipts, and a short timeline of events when you file.
