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. We visited a Boys and Girls Club in Scarborough to give them a whiff of what natural gas smells like, check out the video.

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 called to report a natural gas leak

Follow these safety precautions:

  • Don't use phones or any electronics near the leak
  • Don't turn appliances or lights on or off
  • Don't smoke or use lights or matches
  • Don't start any vehicles or motors

If leaking natural gas is burning, call 911. Don't attempt to put the fire out yourself.

Most often natural gas leaks are detected by smell. However, a hissing sound, damaged connection or dead or dying vegetation in the area around your natural gas meter, appliances or gas lines may also be signs of a leak.
