Identifying a Leak

Pipelines are recognized as the safest method of transporting refined petroleum products and other oil and gas products over long distances. Although pipeline leaks are very rare, it’s important to know the signs and what to do if you suspect a leak.

If you suspect a pipeline leak, stop what you are doing and move to a safe location.

Call 9-1-1 and then call our Emergency Services hotline to ensure public safety: 1-800-361-0608.

How do you know if there is a pipeline leak?

Potential signs include:

  • Dead or discoloured vegetation on or near the pipeline right-of-way.
  • Visible flow or pooling of a petroleum product, like gasoline or diesel.
  • An unusual oil stain on land or the appearance of a sheen or bubbles in water.
  • The smell of gasoline or oil, whether prominent or faint.
