Tenants in Nunavut often face mould or dampness due to cold climate, building design and ventilation challenges. This guide explains tenant and landlord responsibilities under local tenancy rules, practical steps to document problems, when to ask for repairs, and how to escalate unresolved issues. It uses plain language to help renters know how to notify landlords, preserve evidence, and access official forms and the tribunal or court that handles residential tenancy disputes in Nunavut. Whether you rent an apartment, house, or public housing, this summary helps you protect your health, exercise your rights, and reduce the chance of misunderstandings with your landlord.

Causes and health risks

Mould and dampness in Nunavut commonly result from condensation, poor ventilation, snow and ice intrusion, plumbing leaks, or insufficient heating. Damp conditions can increase respiratory symptoms, trigger allergies, and damage building materials. If you or household members have health concerns, document symptoms and environmental conditions and discuss them with your landlord and a health professional. For more about tenant health and habitability standards see Health and Safety Issues Every Tenant Should Know When Renting.

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

Who is responsible for repairs?

Under Nunavut tenancy rules the landlord typically must keep a rental unit in a reasonable state of repair and fit for habitation; tenants must take reasonable care and report problems promptly. Tenants should notify the landlord in writing, give a reasonable chance to fix the issue, and keep copies of all communications. For a clear summary of mutual duties see Obligations of Landlords and Tenants: Rights and Responsibilities Explained. Specific legislation and resources are available from the territorial justice department and related agencies[1].

Keep dated photos and a repair log to document the problem.

Immediate steps tenants should take

  • Document the problem with clear photos, dates and short notes describing where and when you first noticed mould or leaks.
  • Notify your landlord in writing and keep a copy; state the problem, desired repair and a reasonable time for response.
  • Request repairs promptly and keep receipts for any minor emergency expenses you pay with the landlord's prior consent.
  • Use temporary measures to limit damage, such as increasing ventilation or using a dehumidifier while awaiting repairs.

Official forms and escalation

There may not be a single standardized provincial form for every notice in Nunavut. Tenants commonly use a written notice to the landlord describing the defect and requesting repairs; public housing tenants can file repair requests with the Nunavut Housing Corporation; and unresolved disputes may require an application to the tribunal or court that handles tenancy matters in the territory[2][3]. Practical examples:

  • Written Notice to Landlord (no official number): Use this when you first report mould, include dates, photos and a reasonable repair deadline.
  • Nunavut Housing Corporation repair request (public housing): Use this for repairs in public housing units; follow the Corporation's reporting process to preserve your rights.
  • Application to the Nunavut Court or tribunal (forms vary): If repairs are not made, you may need to file an application asking the tribunal or court to order repairs or compensation.
Respond to legal notices within deadlines to avoid losing rights.

FAQ

Who must fix mould in my rental in Nunavut?
Landlords are generally responsible for maintaining a unit in a habitable condition; tenants should report issues promptly and allow access for repairs.
Can I withhold rent until mould is fixed?
Withholding rent is risky and often not allowed; follow written notice steps, document the problem, and apply to the tribunal or court if necessary rather than withholding rent.
How long should I wait for repairs?
Expect a reasonable time for repairs depending on severity; urgent health or safety issues should be raised immediately and followed up in writing if not addressed.

How-To

  2. Send a written notice to the landlord that describes the issue, requests specific repairs, and sets a reasonable deadline.
  3. Request repairs and provide access; keep copies of receipts if you pay for agreed emergency fixes.
  4. If the landlord does not fix the problem, apply to the tribunal or court and attach your evidence and copies of notices.
  5. Take interim health precautions: ventilate, remove mouldy items, and consult a health professional if needed.

Key Takeaways

  • Document mould and dampness with dated photos and a concise repair log.
  • Notify your landlord in writing and keep copies of all communications.
