Tenant Cooling Rights During Heatwaves in Northwest Territories

Maintenance & Repairs Northwest Territories 5 min read · published March 09, 2026 Flag of Northwest Territories

With rising summer temperatures and increased heatwaves in the Northwest Territories, tenants are increasingly concerned about keeping their homes cool and safe. Understanding your rights around cooling, landlord responsibilities, and tenant options is important, especially during extreme weather events. This guide covers the essentials for cooling rights, maintenance duties, legislation, and practical steps to help tenants stay comfortable and healthy in their rental homes.

Landlord Responsibilities for Cooling in the Northwest Territories

In the Northwest Territories, landlord and tenant relationships are regulated under the Residential Tenancies Act (RTA)[1]. While the Act addresses minimum standards for maintenance and health, it does not require landlords to provide air conditioning or cooling systems in rental units. However, landlords must keep rental units in a condition that is safe and healthy for occupants year-round.

Cooling equipment is not mandated by the Act, and landlords aren’t required to provide AC unless your lease says so. If heat is a problem, request practical accommodations in writing and document conditions; contact the Residential Tenancies Office if health or safety is at stake.
  • Heating is mandatory: Landlords are legally required to provide adequate heat, but there is no equivalent mandate for cooling systems such as air conditioning.
  • Fans or window AC units are not guaranteed unless specifically included in your lease.
  • During heatwaves, landlords must still address issues that create unsafe living conditions, such as lack of ventilation or windows that cannot be opened.

Providing a healthy indoor environment is part of the general Obligations of Landlords and Tenants: Rights and Responsibilities Explained, even if specific cooling devices are not required by law.

Is Air Conditioning a Requirement?

Unlike heating or basic plumbing, air conditioning is not considered an essential service under the NWT Residential Tenancies Act. If your unit came with air conditioning or another cooling system, it must be properly maintained by the landlord. Otherwise, you may request permission to install your own system, but this often requires written consent.

Heat-related illnesses can escalate quickly. If you or others are at risk, contact a healthcare provider and report unsafe conditions to your landlord; escalate to the RTO if the issue remains unresolved.

Maintaining Health and Safety During Heatwaves

Extreme heat can pose a serious health risk, especially for vulnerable tenants. While there is no explicit legal right to cooling, landlords are obligated to ensure the premises are not hazardous to tenant health. This is especially important for seniors, tenants with medical issues, or families with young children.

  • Block sunlight using curtains or shades
  • Open windows and create cross-ventilation if possible
  • Use portable fans, being sure to follow manufacturer safety guidelines
  • Stay hydrated and check public advisories during heatwaves

If your apartment becomes dangerously hot due to a failure of ventilation or sealed shut windows, this could be considered a Health and Safety Issue Every Tenant Should Know When Renting. In such cases, you may have grounds to request repairs or modifications for a safe and habitable environment.

How to Address Cooling Issues with Your Landlord

If your unit is unreasonably hot and you believe it could impact your health or safety, it is important to address the issue constructively with your landlord. Document the temperature and living conditions as evidence.

Keep a running log of daily temperatures, dates, and any health or comfort impacts, and save all emails or texts. When you request repairs, propose reasonable targets and timelines in writing to help your case.
  • Communicate in writing: Email or write a letter to your landlord describing the problem and requesting a solution (e.g., repair of stuck windows, installation of a portable fan).
  • Keep a record of all communications.
  • If your landlord fails to respond, you may file a complaint or application with the Residential Tenancies Office (RTO).

Filing a Complaint or Seeking Tribunal Assistance

The official body handling rental disputes in the Northwest Territories is the Residential Tenancies Office (RTO). If you are unable to resolve your issue with the landlord, you can file a complaint or an application for dispute resolution.

  • Form: Application to the Rental Officer (RTA-002)
  • When to use: If your landlord fails to address unsafe conditions during a heatwave despite reasonable notice.
  • How to submit: Complete RTA-002 and submit it in person, by email, or mail to the Residential Tenancies Office. Provide all supporting documentation (e.g., communication records, photos, health impacts).
Before escalating, always try to resolve the issue with your landlord directly. Provide clear documentation and allow a reasonable time for response.
Escalation should come after documenting efforts and attempting resolution; when you file with the RTO, attach all correspondence and evidence to support your claims.

What the Law Covers – and What It Doesn’t

The Residential Tenancies Act (NWT) mostly ensures your rental is safe and fit for occupancy, but it stops short of mandating specific cooling equipment. If you face heat-related health issues inside your home, consider whether a general health and safety argument applies. Severe cases may be reviewed by the Rental Officer, especially when vulnerable tenants are involved.
