Smell Gas? Act Fast!

In its pure state, natural gas is odourless. For your safety, we add an odourant called mercaptan, to give it a distinctive smell. The best way to describe the smell is rotten eggs, but it can also be identified as a blend of other things, such as: sulphur, garbage, and boiled eggs. However it's described, the smell is distinctive and intentional so that people notice and can act appropriately.

Our noses can identify a wide variety of smells. But how accurate are they and can they recognize natural gas? We challenged three families to put their noses to the test. Let’s see how they did:

Signs of a natural gas leak:

  • Smell - a distinctive rotten egg or sulphur like odour
  • Sound - Hissing, roaring or whistling
  • Sight - Damaged connections to natural gas appliances or vegetation that is dead or dying for no reason around your natural gas meter or gas lines

If you suspect a natural gas leak:

  • Act quickly and remain calm
  • Go outside or leave the area immediately
  • Call our 24-hour Emergency Number: 1-866-763-5427
  • Never assume someone else has already called to report a natural gas leak
