Special Tenancy Situations Manitoba 4 min read · published March 29, 2026 Flag of Manitoba

Tenants often discover mould or experience poor indoor air quality that affects health and comfort. In Manitoba, renters have rights to a safe, habitable home and practical steps to address mould, ventilation problems, and related repairs. This guide explains how to identify mould and poor air quality, when to tell your landlord, how to document issues, and which official forms and tribunals can help if repairs aren’t made. It also walks through tenant remedies, timelines, and safety considerations in plain language so you can act confidently. Whether you rent an apartment, house, or room in Manitoba, these clear steps focus on protecting your health and housing stability while navigating provincial rules.

What mould and poor air quality mean for tenants

Mould is a sign that moisture and ventilation problems exist. Even small patches can release spores and odours that worsen asthma, allergies, and other respiratory concerns. Tenants in Manitoba are entitled to a dwelling that meets basic health and safety standards under provincial rules, and landlords are responsible for maintaining the structure and major systems that prevent dampness and mould growth.[2]

In most regions, tenants are entitled to basic habitability standards.

When to notify your landlord and how to do it

Report mould or air-quality problems to your landlord as soon as you notice them and request repairs in writing. If you need more information about health and safety obligations as a renter, see Health and Safety Issues Every Tenant Should Know When Renting.

  • Tell your landlord in writing within a reasonable time, explaining when you first noticed the issue.
  • Use an official form or a dated written notice to request repairs; keep a copy for your records.
  • Keep photos, videos, and a short log of damp events as evidence if the problem persists.
  • If the problem is an immediate health or safety risk, call your landlord and follow up in writing.
Detailed documentation increases your chances of success in disputes.

Documenting the problem and preserving evidence

Good documentation is the strongest tool a tenant has when mould or poor air quality is a dispute factor. Date-stamped photos, a short written log of symptoms (for you or household members), and copies of all written communications help show the severity and timeline of the issue.

  • Photograph affected areas, ventilation units, and any sources of water ingress.
  • Keep a daily or weekly log of visible mould, odours, and any health symptoms.
  • Save copies of emails, texts, repair requests, and receipts for any remediation you pay for.

Official tribunal, legislation, and forms

Disputes about repairs and habitability are handled by Manitoba’s official Residential Tenancies Branch, which explains timelines and options for filing an application for dispute resolution.[1] The provincial law is the Residential Tenancies Act (Manitoba), which sets out rights and responsibilities for landlords and tenants.[2] The branch publishes official forms and guidance on how to file applications and notices.[3]

Common official forms you may need:

  • Application for Dispute Resolution (official form) — use this to ask the branch to order repairs or to resolve a disagreement when a landlord does not adequately respond. Example: you reported mould in writing and the landlord did not repair ventilation; you file the application with your evidence.
  • Notice to Repair or Request for Entry forms — use these when you need to ask the landlord to address a specific repair or to arrange inspection access. Example: a persistent leak behind a cabinet needs inspection and repair.
  • Receipts and Rent Payment Records — keep these when you pay for emergency repairs you asked your landlord to make; they support claims for reimbursement when appropriate.

If you decide to look for alternative housing while a dispute is ongoing, consider searching listings on reliable platforms like Find rental homes across Canada on Houseme to compare options quickly.

Respond to legal notices within deadlines to avoid losing rights.

FAQ

Can I withhold rent if my unit has mould?
Withholding rent without following official procedures can put you at risk of eviction; instead, notify your landlord in writing, document the problem, and consider filing an Application for Dispute Resolution if repairs are not made.

The Residential Tenancies Branch handles disputes about repairs and habitability under the Residential Tenancies Act; you can apply for dispute resolution to request orders for repairs.[1]

How-To

  2. Notify your landlord in writing, request repairs, and include a reasonable deadline (for example, 14 days for non-urgent repairs).
  3. Gather evidence: photos, videos, copies of communications, medical notes if relevant, and receipts for any immediate repairs you pay for.
  4. File an Application for Dispute Resolution with the Residential Tenancies Branch if the landlord does not act; attach your evidence and copies of notices.
  5. Attend the hearing or mediation, present your documentation clearly, and follow any orders or timelines the tribunal sets.
