Your safety comes first

Millions of Ontarians depend on natural gas to stay warm, prepare meals and heat water—it’s a safe, affordable, reliable energy source.

As a property owner, you’re responsible for maintaining the natural gas line that extends past the gas meter into your home and for the safe operation, maintenance and repair of natural gas appliances.

We’re committed to keeping you safe at home, work and play. Review the information below and then download our safety checklist for handy reminders and tips, such as when to test CO alarms or who to call if your basement floods. Print and post it somewhere you can refer to it easily, from season to season.
