What should I do if I smell gas from my furnace?

If you smell gas from your furnace, leave your home immediately and call Enbridge Gas at 1-866-763-5427 from outside your house. Do not turn any lights on or off, don't use electrical switches, and don't try to locate the source of the leak.

Once you're safely outside, call Enbridge's 24-hour emergency line - they will dispatch a technician immediately to shut off your gas supply and investigate the leak. Never ignore a gas smell as natural gas leaks can lead to explosions or carbon monoxide poisoning. Even a small leak can become dangerous quickly, especially in enclosed spaces like basements where furnaces are typically located.

After Enbridge has made your home safe, you'll need a TSSA-licensed gas technician to inspect your furnace and repair any issues before the gas can be restored. In Ottawa's cold climate, gas leaks often occur due to aging connections, cracked heat exchangers, or loose fittings that expand and contract with temperature changes. These repairs must be completed by a licensed professional - attempting DIY repairs on gas appliances is both dangerous and illegal in Ontario.

Do not re-enter your home until Enbridge gives you the all-clear. If you're displaced overnight due to a gas leak, document everything for insurance purposes. Most homeowner's insurance policies cover temporary accommodation costs when your home is uninhabitable due to gas leaks or other emergencies.

Once the immediate danger is resolved, have your furnace thoroughly inspected to prevent future leaks. Regular annual maintenance can catch potential gas leak issues before they become emergencies, keeping your Ottawa home safe through our harsh winters.
