Why radon matters for renters in Northwest Territories
Radon is an invisible, odourless gas that can accumulate indoors and raise long-term health risks for residents. Renters and tenants in the Northwest Territories should know how testing works, what safe guideline levels are, and how to ask a landlord to test or mitigate elevated levels. This article explains practical steps, timelines, and when to involve official bodies so you can protect your health and document concerns clearly. For general renter health guidance, see Health and Safety Issues Every Tenant Should Know When Renting and review local tenancy rights at Tenant Rights and Landlord Rights in Northwest Territories.[1]
Who is responsible for testing and mitigation?
Responsibility can vary by lease and local law. In the Northwest Territories the Residential Tenancies Office handles tenancy disputes and the Residential Tenancies Act sets obligations for landlords and tenants. If your lease is silent, start by asking the landlord in writing for testing and keep copies of communications. If the landlord refuses, you can contact the Residential Tenancies Office for guidance on formal steps and dispute resolution.[2]
How radon testing works
Short guidance to know before you test:
- Serve a written notice to your landlord requesting radon testing and keep a copy.
- Place an approved radon test kit or monitor and leave it for at least 91 days for an accurate long-term result.
- Document results with photos of the device, test dates, and any certificate or lab report you receive.
If radon levels are high: tenant steps and landlord obligations
When tests show elevated radon (Health Canada recommends action at or above 200 Bq/m3), tenants should follow these actions:
- Ask the landlord to arrange mitigation measures such as sub-slab depressurization or improved ventilation; mitigation is a repair/health issue in most jurisdictions.
- If the landlord does not act, submit a formal complaint to the Residential Tenancies Office and include your test documentation.
- Contact public health or environmental health services for radon guidance and to confirm health-based recommendations in your area.
Practical examples and forms
Common official documents and when to use them:
- Written tenant notice or letter to landlord: not always a named government form, but serve it as your first formal step; keep a dated copy and delivery proof.
- Application or complaint to the Residential Tenancies Office: used when informal requests fail; include your test results and communications as evidence.
- Laboratory test report or monitor certificate: this is the primary evidence showing radon concentration and measurement period.
If you decide to move after unresolved high radon, look for safer listings such as Find rental homes across Canada on Houseme and prioritize properties with recent radon testing or mitigation.
FAQ
- Who pays for radon testing in a rental home?
- Often the landlord pays for testing and mitigation, especially where rental habitability or health is affected, but check your lease and local rules; always start with a written request.
- How long should an accurate radon test run?
- Long-term tests of about 91 days are recommended because they account for seasonal variations; short tests give less reliable results.
- What if my landlord refuses to fix high radon levels?
- Document your requests and results, then contact the Residential Tenancies Office to learn how to file a formal complaint or application for dispute resolution.
- Can I order my own radon test as a tenant?
- Yes. Tenants can buy or rent approved test kits or hire a professional monitor and then share results with the landlord and relevant authorities.
