Gas Line Locating in Ontario

Usually, but not by pointing an instrument at the plastic itself. Polyethylene gas pipe is non-conductive, so an electromagnetic locator traces the tracer wire buried alongside it, which means the locate depends on that wire existing, being continuous, and having an accessible point at a riser, meter, valve box, or test station. Where there is no usable wire, the locator falls back to ground penetrating radar, which can image the pipe when soil conditions allow but degrades badly in wet clay, and to acoustic pipe locating where the line can be accessed. Say up front whether the run is plastic and whether tracer wire was installed, because it changes the equipment the service provider brings and what they can honestly promise. If nothing produces a confident trace, the right answer is to expose the line with vacuum excavation rather than dig on an assumption.

No. A suspected gas leak is an emergency, not a scheduling problem. Leave the area on foot immediately and take everyone with you, and do not light anything, operate switches or garage doors, use a phone, or start a vehicle while you are still near the smell. From a safe distance, call 911 and your gas utility’s emergency number; gas utilities respond to reported leaks around the clock. Treat a hissing or roaring sound near a gas line, bubbling in standing water, and a patch of dead or dying vegetation over the run the same way. Locating and leak pinpointing happen after the line has been made safe, never before.

Private locating is quoted per job rather than off a published rate. What moves the number is how much ground has to be covered, how many utilities are in play, whether the lines are metallic or plastic, how reachable the meters, valves, and tracer wire access points are, and whether you need surface marks only or a drawing and GPS data as well. Across Ontario the number also moves with travel distance and local ground conditions, so companies quote the specific job. Describe it once through Utility Hotline and locating companies working that part of Ontario send you their own quotes.

Only on the public side. Ontario One Call (1-800-400-2255) is free, is required by law before excavation in most jurisdictions, and notifies its member facility owners so they mark the lines they own, which generally means up to the meter or the right-of-way. Membership is not universal, so how much of a service lateral gets marked can vary from one system to the next. Nothing on the private side, meaning past the meter or the property line, is in scope anywhere in Ontario, and that is the ground a private locating company covers. Place the ticket, book the private locate, and use both.

Coverage is settled one request at a time rather than off a published service-area map. Gas Line Locating requests arrive from cities across Ontario, spanning the Central Canada, and go to the companies working that particular ground, since gas lines are routine work for a private locating company. Coverage runs deeper around the larger metros, and some crews travel for rural, agricultural, and multi-site work. Tell us the job site and we send your request to the companies covering it.
