Landowners and neighbors

Whether you’re planting a tree, digging a trench or building a fence, you need to be aware of the underground utilities  including gas, electric and water  on your property before you dig. Safe digging is as simple as calling your local One-Call Centre or visiting ClickBeforeYouDig.com three to five business days before starting your job.


I won't put a post in the ground without making sure you guys have been here and marked everything.”

Signs of a potential pipeline leak

Although a pipeline leak is rare, it is important to know how to recognize the signs. Use your senses of smell, sight and hearing to detect a potential pipeline leak.

What you may smell


Natural gas
  • Transmission lines that transport natural gas across Canada are rarely odourized, but may have a slight hydrocarbon smell. Distribution lines that transport natural gas to homes and businesses are odourized and could smell skunk-like or similar to rotten eggs.
Oil
  • Many petroleum products have a distinct smell. Crude oil can possess a rotten egg, gasoline, tar or skunk-like odor.
