Home safety rules do not always make headlines, but some changes are important to pause and take note of. As of January 1, 2026, Ontario updated its Fire Code to expand where carbon monoxide detectors are required in homes.

In this video, I walk through what has changed, who it applies to, and why it matters for homeowners, buyers, and sellers across Ontario. Here are the key takeaways:

What Has Changed Under the New Rules

• Carbon monoxide detectors are now required on every level of the home, not just near sleeping areas.
• This applies to homes with a fuel-burning appliance, a fireplace, or an attached garage.
• The rules are already in effect as of January 1, 2026.

Which Homes Are Affected

• Detached homes, semi-detached homes, townhouses, and cottages.
• Condominium units where a fuel-burning appliance, fireplace, or attached garage is present.
• In apartment and condominium buildings, public corridor requirements are handled by building management.

Carbon monoxide is colourless and odourless, which is why these updates focus on earlier warnings and safer exits. For many homeowners, this may simply mean checking existing alarms or adding an additional unit on another floor.

Home safety is something Melanie and I always keep an eye on, especially when rules change quietly in the background. If you have questions about how these requirements apply to your home or a property you are considering buying or selling, feel free to reach out anytime.
