Carbon Monoxide

Important note: If your carbon monoxide detector sounds or you believe you're suffering symptoms of carbon monoxide poisoning, exit the building or vehicle and call the fire department using 911!


The carbon monoxide regulation (O. Reg. 194/14) has now become law in Ontario and comes into force as of October 15, 2014.  O. Reg. 194/14 amends the Fire Code and introduces mandatory installation, replacement, testing and maintenance requirements for CO alarms in residential dwellings.  It is the owner’s/landlord’s responsibility under the Ontario Fire Code to ensure both installation and maintenance of carbon monoxide alarms.  Both O. Reg. 194/14 as well as the Fire Code (amended to include the new CO provisions) are available through e-laws.
