Detecting a Natural Gas Leak

If you suspect a natural gas leak, immediately call the TransGas 24-hour emergency line at 1-306-777-9800. 

This number is also posted on all of our gas line marker signs.

The natural gas in many transmission lines is not odourized with the additive that gives the gas a sulpher or rotten egg smell. If there is a leak, you may not smell the scent of rotten eggs.

While they rarely occur, here’s how to spot a possible leak: 

Visually

• A steam-like cloud in the air or a frost-like appearance on the ground when the temperature is above zero
• Discoloured plants or dead/dying vegetation along the right-of-way
• Dirt blowing up from the ground
• Bubbling water in wet areas

By sound

• If you hear an unusual hissing, whistling or roaring noise, there may be a natural gas leak

By smell

• You may smell an odour similar to diesel fuel, light oil or propane
