How Yukon Tenants Can Address Mould and Air Quality Issues

Safety & Security Yukon 5 min read · published March 09, 2026 Flag of Yukon

If you're renting in Yukon and discover mould or indoor air quality issues, it's important to understand your rights and how to get help. Mould can threaten your health and must be taken seriously. This guide explains what tenants and landlords must do, what steps you can take, relevant legislation, and support options.

Under Yukon law, landlords must keep rental units safe and habitable and address health risks like mould promptly. If repairs aren’t made, you can file a dispute with the Yukon Residential Tenancies Office to seek a remedy.

Understanding Mould and Indoor Air Quality Issues in Yukon Rentals

Mould grows in damp, poorly ventilated areas and can cause allergic reactions or worsen health conditions like asthma. In rental homes, mould or persistent dampness can indicate problems with the property such as leaks or insufficient ventilation. Both tenants and landlords share certain responsibilities for keeping homes safe and habitable.

Why Indoor Air Quality Matters

Poor air quality doesn't just mean discomfort. Exposure to mould spores can cause respiratory issues, trigger asthma, and even lead to more serious health effects for children, seniors, and those with weakened immune systems.

Mould is often a sign of a moisture problem (leaks, condensation, ventilation). Resolving the underlying moisture issue is essential, not just cleaning mould off surfaces.

Landlord and Tenant Responsibilities for Mould

Under Yukon's Residential Landlord and Tenant Act[1], landlords must provide and maintain rental properties in a state that is safe and fit for habitation. That includes addressing issues that could affect health, like mould or air quality caused by water intrusion, ventilation problems, or building defects. Tenants are responsible for keeping the rental clean and promptly reporting maintenance issues.

  • Landlords must fix leaks, address building faults, and ensure repairs that impact safety and health.
  • Tenants should report signs of mould or air quality problems—as soon as they're noticed—and take reasonable care not to contribute to damp conditions.

What to Do if You Discover Mould or Air Quality Issues

As a tenant, your first step is to let your landlord know, in writing, about the mould or problem area. Describe the affected area, what you've noticed (smell, visible growth, dampness), and the impact on your living conditions. Keep a copy for your records.

Tip: include the date you first noticed the mould, attach photos, and note any health symptoms; send your notice in writing (email or letter) to create a reliable record.

If the issue poses a risk to health or safety and your landlord doesn't respond promptly, you may have the right to request repairs, withhold rent in serious situations (as outlined by law), or make an official complaint. Always use the proper process—do not simply stop paying rent without written direction from the Residential Tenancies Office.

Caution: witholding rent without an order can jeopardize your rights; use the Residential Tenancies Office process to obtain proper authority before withholding payments.

Common Signs of Mould and Air Quality Concerns

  • Visible spots of black, green, or white growth on walls, ceilings, or windows
  • Musty odours or persistent dampness
  • Condensation on windows or walls
  • Unexplained allergy or respiratory symptoms worsening at home

If you're unsure about your symptoms or need inspection, you can contact Environmental Health Services via Government of Yukon for advice.

Fact: Environmental Health Services can assess health risks and advise actions; if a landlord won’t address a serious risk, contacting them is a legitimate step.

Steps for Tenants: How to Seek Action and Repairs

  1. 1. Notify your landlord in writing. Clearly state the problem and ask for repairs or inspection. Attach photos if possible.
  2. 2. Give your landlord a reasonable opportunity to investigate and fix the problem.
  3. 3. Document everything. Keep a record of communication, photographs, and any worsening of the issue or health symptoms.
  4. 4. If no action is taken: File a complaint with the Yukon Residential Tenancies Office (RTO), the official authority for rental disputes in the territory.
Tip: Having detailed records can help your case if you need to escalate your complaint to the RTO or seek further remedies.
