You can’t see or taste natural gas so we made sure you can smell it. A harmless gas called mercaptan is added to natural gas to make it smell like rotten eggs (or sulphur). Natural gas isn’t toxic but it’s highly flammable. Here’s what to do if you smell that smell:

DO get everyone out of the house as soon as possible.
DO call Union Gas at 1-877-969-0999 or 911 from a neighbour’s home or a safe distance away.

DON'T call from inside your home or garage.
DON'T turn electrical switches or appliances on or off.
DON'T smoke or use lighters or matches.
DON'T start motors or motor vehicles on the property.

Make sure everyone in your household knows what to do if they smell a gas leak. Visit to learn more about natural gas safety today.

Smoke alarms and carbon monoxide (CO) alarms can’t detect a gas leak. For added protection, get a natural gas alarm, or a combination natural gas/smoke/CO alarm, available at most hardware and home improvement stores.
