About Natural Gas

What is natural gas?

Natural gas is the cleanest burning fossil fuel and is produced from decomposing plants and animals, pressed for millions of years under tons of rock and soil. It is composed of 95 percent methane, four per cent ethane and one per cent nitrogen, propane, butane and other gases. This raw gas is sent to a processing facility to become predominantly methane.

For more information on natural gas, download our Safety Data Sheet (SDS) in English or French, or visit the Canadian Gas Association.

What does natural gas smell like?

In its pure state, natural gas is odourless. To help identify a gas leak, we add a substance called Mercaptan to make the gas smell like rotten eggs.

Make sure your family members can identify the smell of natural gas and know what to do if a leak is suspected.

How is natural gas transported to my home?

Most of the natural gas used in Canada comes from Alberta and other western provinces. Recently, rich reserves of this resource have been discovered off the coasts of Nova Scotia, Newfoundland and Labrador. Some natural gas also comes from the United States.

Natural gas is transported through a network of gas pipelines that extends across North America, right to your home.

Several distributors, such as Enbridge, control the redistribution of natural gas. View our service area.

How safe is natural gas?

Natural gas is one of the safest sources of energy. However, it is highly flammable and, like any burning fuel, can produce odourless carbon monoxide.

For your safety, Enbridge provides free 24-hour emergency service every day of the year.
