Disconnect gas

Ensuring worker and public safety is our number one priority. Before any demolition work can begin on a property, the natural gas service must be safely disconnected by Enbridge Gas and natural gas lines must be located to avoid damage.

What you need to do

Before you dig - The law requires you to contact Ontario One Call to locate and mark underground pipes. Call 1-800-400-2255 or submit your request online. This 24/7 service is offered free of charge.

Disconnect gas - Contact us at 1-877-362-7434 to get started. We require a minimum of 44 days from the time your payment is received to the date the work is completed.

What we will do

  • Apply for a permit with the municipality.
  • Visit the site to assess the necessary resources and the cost to complete the work.
  • Provide a quote for the expected work. Our fee is regulated by the Ontario Energy Board. We require written confirmation that the property owner accepts these charges and consents to the cut off. If we don’t receive confirmation by a specified date, we can’t proceed with the work. At that point, the work request will be terminated.
  • Request underground utility locates for the area where we’ll be working.
  • Contact you to provide a scheduled cut-off date.
