Carbon Monoxide Detector Requirements in Manitoba

Safety & Security Manitoba 3 min read · published June 24, 2026 Flag of Manitoba

As a renter in Manitoba, you should know where carbon monoxide (CO) detectors must be installed, who is responsible for providing and maintaining them, and what to do if a detector is missing or not working. This guide explains tenant and landlord responsibilities in plain language, practical steps to stay safe, and how to use official forms or request dispute resolution if the issue is not fixed. It focuses on real situations tenants face—rent increases, repairs and safety concerns—so you can act confidently and know where to get help in Manitoba.

What the law requires

Manitoba requires functioning carbon monoxide detectors in rental homes where fuel-burning appliances, attached garages, or other CO sources are present. The Residential Tenancies Branch is the provincial body that oversees these requirements and dispute resolution services [1]. Landlords generally must provide detectors and ensure they work at the start of a tenancy; tenants must report issues promptly and allow reasonable access for repairs.

Carbon monoxide is an odorless gas that can be deadly if detectors are missing or not working.

Basic compliance checklist

  • Safety: Ensure a working CO detector is installed outside each sleeping area and on every storey with potential CO sources.
  • Documentation: Keep records and photos of detectors and any repair or replacement requests.
  • Maintenance: Replace batteries and test detectors regularly; follow manufacturer instructions for lifespan and replacement.
  • Report: Notify your landlord in writing if a detector is missing or faulty, and request repair or replacement.

If a landlord does not act after you report a problem, you can apply for dispute resolution through the Residential Tenancies Branch. The RTB website has the official forms and guidance for filing applications [2].

Tenant and landlord responsibilities

Landlords are responsible for supplying and installing detectors and ensuring the rental unit is safe at the beginning of your tenancy. Tenants are responsible for routine upkeep, such as testing detectors and replacing batteries if the device uses replaceable batteries. Always report problems in writing and keep a copy of the message.

Send repair requests by email or text and save a dated copy as proof.

If you are searching for a new rental and want to confirm detector or safety features before you sign, consider using housing search tools such as Houseme - your rental solution in Canada [3] to find listings and contact landlords about safety details.

When to use official forms

  • Application for Dispute Resolution: Use this when a landlord fails to fix a missing or defective CO detector after you reported it; for example, you reported the issue in writing and waited the required time without action.
  • Notice to End Tenancy (if applicable): Only use this if you and your landlord agree to end the tenancy due to an unresolved safety issue and you both follow the notice rules.

Practical example: You texted your landlord about a dead CO detector and gave them 7 days to fix it. If nothing happens, file an Application for Dispute Resolution with the Residential Tenancies Branch and include dated copies of your messages and photos.

FAQ

Who must provide carbon monoxide detectors in a rental?
Landlords must provide and install required CO detectors before a tenancy begins; tenants should test them and report problems immediately.
What should I do if my detector is not working?
Report it in writing to the landlord, keep a copy as proof, and if the landlord does not act, apply for dispute resolution with the Residential Tenancies Branch.

  2. Record tests: Keep a dated log or photos of your tests and any communications about detector issues.
