Legal requirements in Alberta

What tenants should do after an alarm

If a carbon monoxide alarm sounds or you suspect a leak, follow these practical steps immediately and document everything.

  • Vacate the premises immediately if anyone is feeling unwell or if the alarm is persistent.
  • Call emergency services (911) if anyone has symptoms such as headache, nausea, dizziness, confusion, or loss of consciousness.
  • Document the incident with date, time, photos of the alarm and detector, and any symptoms you or others experienced.
  • Contact your landlord right away to report the alarm and request immediate inspection and repair.
  • If the landlord does not act promptly, consider filing a formal complaint or dispute with the provincial dispute service.
If you or others are ill, prioritize evacuation and emergency care before documentation.

FAQ
