Asbestos Disclosure Requirements for Ontario Tenants

Safety & Security Ontario 3 min read · published June 24, 2026 Flag of Ontario

Living in an older building can raise questions about asbestos and how it affects renters. As a tenant in Ontario, you have rights to a safe home and to information about hazards that affect habitability. Landlords have responsibilities under provincial law and health or occupational safety rules, and there are practical steps tenants can take if they suspect asbestos: ask for records, request testing, or report safety concerns to the right authorities. This guide explains what Ontario law requires, where to find official forms and tribunal help, how to document concerns, and what to expect during inspections or repairs, using clear language aimed at tenants who need actionable, trustworthy advice.

What Ontario law says about asbestos

Ontario's Residential Tenancies Act, 2006 requires landlords to maintain a rental unit in a good state of repair and fit for habitation[1]. The RTA does not include a specific asbestos disclosure form, but other laws and workplace regulations require information when asbestos work is done. For tenant safety, Ontario's asbestos guidance and occupational rules explain how building owners and contractors must handle asbestos and notify affected people[3].

Landlords must ensure units are safe even if a specific asbestos disclosure form is not required under tenancy law.

Landlord and tenant responsibilities

Landlords should know where asbestos-containing materials are located, avoid disturbing them, and hire licensed professionals for removal or repair. Tenants should report concerns promptly and keep written requests and records. If a landlord takes no action, tenants can seek remedies through the Landlord and Tenant Board[2] or health and safety authorities.

  • Ask the landlord in writing for any asbestos records or surveys.
  • Request a licensed asbestos inspection or testing before any renovation or work that could disturb building materials.
  • Keep dated copies of emails, photos, and receipts as evidence of requests and any remediation work.
  • If urgent health or safety risks are ignored, apply to the Landlord and Tenant Board or contact local public health for next steps.
Clear written requests and photos improve the chances of timely repairs or safe abatement.

When to involve other authorities

If workers are at risk during repairs, the Ministry of Labour enforces asbestos rules for workplaces; for uncontrolled exposure affecting residents, contact public health or your municipality. The Landlord and Tenant Board handles disputes about repairs and maintenance and can order remedies or rent reductions.[2]

How to get an inspection or repairs

  1. Contact your landlord in writing and clearly request an asbestos inspection or survey, stating the location and your concerns.
  2. Ask the landlord to hire a licensed asbestos assessor and to provide the assessor's report in writing.
  3. If the landlord refuses, file an application or request a hearing with the Landlord and Tenant Board to seek repairs or abatement orders.
  4. For immediate health risks or if workers may be exposed, contact the Ministry of Labour or local public health for enforcement and guidance.
Keep all communications and any test reports stored safely and backed up.
