Toronto – November 4, 2026 – Carbon Monoxide Awareness Week is a timely reminder that a few simple precautions can help Ontario homeowners keep their homes and families safe.
“Home safety starts with being aware and building a few good habits,” says Peter Balasubramanian, President and CEO of Tarion, the independent consumer protection organization that administers Ontario’s new home warranty program. “Testing your carbon monoxide alarms, maintaining equipment, and keeping vents clear and air flowing are some straightforward steps that homeowners should make sure are part of their regular maintenance routine.”
This year, there are updated carbon monoxide alarm requirements under Ontario’s Fire Code. As of January 1, 2026, existing homes with a fuel-burning appliance, fireplace, or attached garage must have a carbon monoxide alarm adjacent to each sleeping area and have one on every floor of your home. Homeowners that have any questions about how the requirements may apply to their home are encouraged to contact their local fire department if they have questions.
This Carbon Monoxide Awareness Week, Tarion is encouraging homeowners to take the following practical steps:
Check your carbon monoxide alarms
Test each alarm regularly and follow the manufacturer’s instructions for installation, maintenance, battery replacement, and end-of-life replacement. Check that alarms are installed in the required locations and consider marking the replacement date directly on each device so it is easy to remember. When purchasing a new alarm, look for the mark of a recognized Canadian standards testing agency, such as CSA, cUL, ULC or cETL.
Maintain fuel-burning appliances
Have furnaces, fireplaces, water heaters and other fuel-burning appliances inspected and maintained by a qualified professional in accordance with the manufacturer’s recommendations. Check furnace filters regularly and clean or replace them when they become dirty to help keep the air in your home clean and circulating freely.
Keep vents and chimneys clear
Snow, ice and debris can block exterior vents and chimneys. Check them regularly, particularly following heavy snowfall or severe weather, and keep the openings clear so appliances can vent properly.
Use vehicles and fuel-burning equipment outdoors
Never leave a vehicle running inside an attached garage, even when the garage door is open. Barbecues, generators and other portable fuel-burning equipment should only be used outdoors and away from doors, windows, vents and other openings into the home.
Know what to do if an alarm sounds
Make sure everyone in the household recognizes the alarm and knows what to do. If a carbon monoxide alarm sounds, leave the home immediately and call 9-1-1 or local emergency services from outside. Do not return until emergency responders say it is safe. Possible signs of exposure can include headache, nausea, dizziness, confusion and drowsiness, but a working alarm provides the most important early warning because carbon monoxide cannot be seen or smelled.
Whether you have recently moved into a new home or have lived there for years, Carbon Monoxide Awareness Week is a good opportunity to walk through your home, check your alarms and make these precautions part of your regular maintenance routine. A few minutes of attention can help keep your home safe throughout the heating season and all year long.
