Dealing with Mould and Air Quality in Northwest Territories Rentals

Mould and indoor air quality problems can quickly turn your rental into an unhealthy place to live. If you’re renting in the Northwest Territories, it's important to know how to spot mould, what your rights are, and what steps to take when problems arise. Protecting your health and comfort starts with clear information and knowing where to seek help.

Understanding Mould and Indoor Air Quality Risks

Mould thrives in damp spots and can lead to respiratory problems, allergies, and other health issues. Poor indoor air quality, including lingering moisture, dust, and pollutants, poses further risks to your well-being. Spotting early signs, such as musty odours, visible spots, or excessive condensation, is crucial.

Your Rights and Responsibilities Under Northwest Territories Law

Rental housing in the Northwest Territories is covered by the Residential Tenancies Act of the Northwest Territories^[1]. Both tenants and landlords must work together to maintain a safe, healthy environment.

• Landlord’s duty: Ensure the rental is maintained in a safe, habitable condition, free from hazards including mould.
• Tenant’s duty: Keep your space reasonably clean and promptly alert your landlord of issues that could lead to damage or health risks.

Common Causes of Mould in Northern Rentals

Due to the cold climate, rental homes in the Northwest Territories may develop moisture problems, leading to mould growth on windows, walls, or ceilings. Inadequate ventilation and water leaks are frequent culprits. Prevent mould by ensuring bathroom and kitchen fans work and reporting water leaks quickly.

What to Do If You Discover Mould or Air Quality Problems

Here’s what to do when you notice mould or suspect indoor air quality issues in your rental:

• Document the issue: Take clear photos and note locations, dates, and any health symptoms.
• Notify your landlord in writing: Send a detailed letter (email or traditional mail) describing the problem and requesting urgent repairs. Keep a record of your communication.
• Give reasonable time to respond: Landlords must act within a reasonable timeframe to address repair and safety issues.
• Keep records: Keep copies of all correspondence, photos, and any medical documentation if the issue affects your health.

Making a Formal Complaint or Requesting Inspection

If your landlord doesn’t respond, you can take further steps:

• Apply to the Rental Office of the Northwest Territories: They handle all tenancy disputes and maintenance complaints.
• Form: Application to the Rental Officer (Form 1) – Used to bring unresolved maintenance, repair, or health/safety issues to the attention of the Rental Office.
