New carbon monoxide alarm rules every homeowner needs to know

Clarington has launched a spring public education campaign to help residents understand new carbon monoxide (CO) alarm rules now in effect under Ontario’s Fire Code.  

As of January 1, 2026, all existing homes, multi‑unit dwellings, and care occupancies with an attached garage or appliances that use natural gas, propane, oil, or wood must have CO alarms installed on every level of the building and outside every sleeping area.  

Carbon monoxide is an invisible, odourless, and tasteless gas, which means the only way to know it’s present is with a working alarm. More than 65 per cent of carbon monoxide‑related injuries and deaths in Ontario happen in the home, according to the Province’s carbon monoxide safety guidance – making early detection essential.  

Clarington Fire and Emergency Services is encouraging residents to take a few minutes to look around their homes and make sure alarms are installed where needed and working as they should. If you’re a tenant, notify the property owner immediately if your alarms are disconnected or not working properly. 

Follow these life-saving habits to protect you and your family: 

• Monthly: Test all alarms
• Annually: Replace alarm batteries
• Every seven to 10 years: Replace alarm units (following manufacturer instructions)
• Don’t ignore the CHIRP! That’s your alarm warning you of a low battery or that it’s time for a replacement. Take action immediately to stay protected
