Mold issues in rental homes are a serious health and legal concern. While many high-profile mold case wins come out of Ontario, Alberta tenants are increasingly aware of their own rights and protections. By understanding how successful tenants in Ontario have approached mold disputes, you can better navigate similar problems here in Alberta.

Why Mold in Rentals Matters

Mold can cause significant health problems and property damage. Alberta law requires landlords to provide safe, habitable housing. Mold or water damage that is not addressed could violate these requirements. Learning from Ontario's experiences, Alberta tenants have strong reasons—and legal grounds—to seek action when mold is found.

Lessons from Ontario Mold Case Wins

Ontario tribunals have ruled in favour of tenants when landlords failed to repair mold or address underlying moisture issues. Key takeaways include:

• Documenting the mold problem with photos, dated notes, and correspondence is essential.
• Reporting the issue in writing to the landlord as soon as it’s discovered.
• Following up persistently if repairs are not made.
• Seeking compensation for harm or loss only after giving the landlord a reasonable chance to fix the problem.

Even though legal decisions in Ontario don't set precedents in Alberta, tenants here can use similar documentation and complaint processes to strengthen their cases.

Your Rights in Alberta: Understanding the Law

In Alberta, the Residential Tenancies Act (RTA) requires landlords to maintain rental properties in a good, safe state of repair and fit for habitation^[1]. If mold is caused by factors beyond the tenant's control (e.g., leaks, poor ventilation not caused by the tenant), addressing it falls on the landlord.

Common Steps for Alberta Tenants Facing Mold Problems

1. Take clear photos/videos of affected areas, noting dates.
2. Report the mold issue to your landlord in writing, keeping a copy for yourself.
3. If there's no quick response, send a formal registered letter repeating your concerns and requesting repairs.
4. If the landlord refuses or ignores you, prepare to contact the Residential Tenancy Dispute Resolution Service (RTDRS) or provincial health authorities.

Tip: Keep all correspondence and evidence organized. This helps if your case goes to dispute resolution.

Who Handles Tenant Disputes in Alberta?

In Alberta, the Residential Tenancy Dispute Resolution Service (RTDRS) provides a faster, less formal alternative to court for rental disputes. The RTDRS can order repairs, compensation, or even end a tenancy over serious problems like mold.

Relevant Forms and How to Use Them

• Application for Tenancy Dispute Resolution (RTDRS Form 1) – Use this form to file a dispute if the landlord won't fix mold or repair issues. Download the RTDRS Application Form. Example: After giving your landlord at least 14 days' notice to repair, you can apply to the RTDRS using this form to request an order for repairs or compensation.
• Notice to Remedy a Substantial Breach (Form 14-Day Notice) – If mold affects health and safety, tenants can serve this notice to landlords to demand urgent repair. If not resolved in 14 days, the lease can be terminated. Official 14-Day Notice Form

Your Obligations: What Tenants Must Do

Tenants must keep the rental reasonably clean and not cause damage, but they are not responsible for repairs due to ordinary wear, leaks, or construction defects. Review your duties in Obligations of Landlords and Tenants: Rights and Responsibilities Explained.

Health and Safety: When to Get Help

If mold poses a serious health risk, contact Alberta Health Services Environmental Public Health (AHS EPH) for inspection and direction. Unresolved mold may also fall under "emergency repairs" according to Alberta legislation.
