Call Before You Dig to Locate Underground Lines

Call Before You Dig to Locate Underground Lines

If you plan to do any digging, make sure you contact ON1Call at least a week before you dig. Don’t risk rupturing a gas line or cutting through a communications cable. Call if you are planting a tree, putting in a deck or fencing, or even just driving in a stake or post. Some pipes and lines are just below the surface.


Open 24 hours a day, seven days a week, ON1Call is a free service that shows you where gas lines, water mains, electrical or fibre-optic lines are located on your property.  Call 1-800-400-2255 or go to www.on1call.com to make your locate request. ON1Call will need:

  • the address where the digging will be taking place (including the nearest intersection)
  • a description of the work being done
  • your phone number and email address

Severed underground lines could cause explosions, flooding and/or a loss of essential services – and you could even be liable for restoration costs and potential legal action. Learn more.
