Call Before You Dig – line location

Are you planning to build a fence? Or digging a hole for any reason? We can help you stay safe. Calling before you dig can prevent:

  • service outages;
  • equipment damage;
  • costly repairs;
  • environmental pollution;
  • personal injury or death.

Call before you dig to arrange for us to check and mark your property for electrical and/or natural gas lines. The service is free to locate Manitoba Hydro-owned underground facilities.

Call 1-888-624-9376 or in Winnipeg call 204-480-1212. Remember to also contact other utilities.

Manitoba Hydro is not a member of any external call/click before you dig services. You must call us directly before you excavate to mark all electrical and/or natural gas lines. We cannot accept email requests for appointments.

View information about safe excavation.

A Safety Watch is required for all excavations within 3 metres of a cable or pipeline.

From April 1 to October 31, call at least one week ahead to book an appointment. From November 1 to March 31, we require at least three business days notice.

Your responsibilities

  • A locate form must be obtained prior to excavation, and specific instructions on the form must be followed.
  • If work has not started within 14 days after the locate was completed, you must again notify us to re-mark the work area and provide an updated electric and/or natural gas facilities locate form.
  • Contractors must ensure that everyone on the worksite is aware of the presence of all gas and electric facilities and ensure that the locate form is kept at the excavation site until the excavation and backfill are complete.
  • The location markings must be maintained and kept visible by the person or contractor doing the excavation. Be careful that site operators do not remove the line location markings.

Homeowner information.

Professional excavators information.

In the event that Manitoba Hydro fibre optic cables are present contractors will be referred by the Manitoba Hydro Facilities Locator to the Manitoba Hydro communications department for more information.

Note: Manitoba Hydro only locates facilities that it owns and has no knowledge of or responsibility for privately-owned facilities. Electric conductors or gas pipes installed past the meter are owned privately by the property owner and, at times, are installed below ground before it enters the building. Outbuildings that are heated or have electrical power, wells, septic system pumps and hot tubs are other examples where privately-owned buried facilities may exist.

Planning & designing large projects

Determining the location of existing Manitoba Hydro Underground Structures within the work area should be one of the first priorities of any work. Knowing the location of all utilities infrastructure allows the third party to plan work proactively, mitigating the need for costly design changes or delays during construction.


All projects involving ground disturbance must submit detailed drawings of proposed work and include any gas or electrical line in the work area. Drawings shall be submitted at least four weeks before the start of any excavation work to the Gas Distribution Engineering Department.

Drawings will be reviewed by Manitoba Hydro at no cost and a letter providing details of any work restrictions, specific requirements or costs will be provided to the contractor.


Contact Manitoba Hydro in Winnipeg at 204-480-5900 or outside Winnipeg at 1-888-624-9376.

You will be referred to the local office for further instruction.
