As a tenant in Ontario you have the right to live in a safe rental home and to be told about known hazards like asbestos or lead. This guide explains what tenants can expect from landlords, practical steps to report suspected asbestos or lead, and how to request testing or repairs without legal jargon. It covers which provincial rules and tribunal handle residential tenancy issues in Ontario, what official forms you may need, and everyday examples so you can act confidently when you find crumbling plaster, peeling paint, or dust that might be hazardous.
Asbestos and Lead in Ontario Rentals
Older buildings may contain asbestos in insulation, floor tiles, or textured ceilings, and lead in paint or plumbing. Landlords are responsible under Ontario law to maintain rental units in a good state of repair and fit for habitation; tenants can request repairs or apply to the Landlord and Tenant Board if hazards are not addressed. See the Residential Tenancies Act for the legal obligations that apply in Ontario.[1]
Recognizing common signs
- Cracked or damaged drywall, falling ceiling texture, or disturbed insulation that releases dust.
- Peeling or chipping paint on window sills, doors, or trim in buildings built before 1990.
- Unexplained dust, persistent discoloration, or a musty smell near old pipes or renovation areas.
If you suspect asbestos or lead, avoid disturbing the area, limit access, and notify the landlord in writing explaining what you found and where. Keep a copy of your message and photos.
What landlords must do
- Investigate reported hazards and arrange professional testing or safe containment when necessary.
- Arrange and pay for required repairs or abatement to make the unit safe and habitable.
- Provide clear instructions and timelines to tenants about access and safety while work is done.
When repairs are urgent or a landlord does not act, tenants can request help through formal channels and, if necessary, file an application with the Landlord and Tenant Board for an order to compel repairs or seek compensation.[2]
How to report, document, and request action
Follow clear steps when you find possible asbestos or lead: gather evidence, inform the landlord in writing, request professional testing, and keep records. If the landlord does not respond, you can file an application with the Landlord and Tenant Board or contact local public health authorities for lead concerns. Use plain, dated messages and keep copies of everything you send or receive.
- Gather evidence: take photos, note dates, describe symptoms or visible damage, and keep any related receipts.
- Notify the landlord in writing and request testing or repairs; be specific about location and hazard.
- If no prompt action, contact your local public health unit for lead advice or the Ministry of Labour for asbestos guidance.
- File an application with the Landlord and Tenant Board if the landlord refuses to act or if repairs are delayed.
Example: You find flaking paint around a window sill and report it to the landlord by email with photos. If the landlord does not arrange testing within a reasonable time, you send a follow-up and prepare to file with the Board, attaching your written requests and photos as evidence.
Tenant forms and official resources
Official forms and guidance are available from provincial authorities. Tenants looking to start a formal application or find model letters can use the Landlord and Tenant Board forms and guidance, and consult public health or workplace safety pages for testing guidance.[2]
- Landlord and Tenant Board forms (application forms and guides) — use these to file applications about repairs or tenant rights.
- Health Canada and Ontario public health guidance on lead — explains exposure, testing, and prevention steps.[3]
- Ontario Ministry of Labour resources on asbestos controls for building work and contractor requirements.
Practical tips for tenants
- Ask for written confirmation of any testing or remediation schedule and a copy of the contractor report once work is finished.
- If you have health concerns, see a physician and ask for documentation linking symptoms to a suspected exposure.
