Underground locates

Digging near Your House?

Before you dig, call Ontario One Call at 1-800-400-2255 or visit their website.

The City and other services have underground locates running in many backyards, front yards and side lots. Underneath your house, you could find:

  • Gas pipelines
  • Electrical services
  • Telephone and cable TV infrastructure
  • Water and sewer connections
  • Streetlight or traffic signal wiring

Ontario One Call co-ordinates with all organizations who own infrastructure in your area.

Therefore, all residents and excavators must call before they dig. Locates are free to obtain and should be requested at least 5 days prior to any planned excavation. You may not proceed with your digging until all locates are identified. If locates are not obtained and infrastructure is damaged, the homeowner and/or contractor is 100 per cent responsible for all costs associated with repairs.

Do You Need Emergency Locates?
