What is the difference between a private and public utility locate?

Public utilities are defined as those owned by large utility providers and include the mass distribution network of services such as sanitation, water, gas, electricity, and communication which connect us together. This includes connecting us to our cities, homes, and places of work.  These utilities are considered publicly managed and owned up to a cut off point otherwise known as a “demarcation point”, which is usually situated on the outside of a house, building, property, or in maintenance and mechanical rooms. The cut off or “demarcation point” is usually identified by a metering system, transformer or vault. Utilities that continue after the demarcation point are owned by the property owner and considered private utilities. Private utilities may include:

  • Lights or signs on the property
  • Buried storage tanks and lines, including fuel tanks and water discharge tanks
  • Electrical lines going out to sheds or secondary buildings
  • Sewer and septic tanks, systems and piping
  • Security cameras
  • Automatic gates, parking kiosks
  • Gas lines to bbq or pool heaters


Keeping Employees safe is very important when it comes to the working in the unknown.  Its often very hard to understand the dangers of excavating and drilling when the hazards are buried beneath your feet.  Imagine if you could easily see Ontario’s underground world, to expose how thousands of kilometers of unseen water, oil, electric, sewage and telecommunication infrastructure was keeping businesses and homes connected with data, power, heat, water, sanitation and communications.  Ontario One Call can help to identify registered underground services in the area, except they do not identify and mark privately owned services.  Landshark Locates will identify and mark the existence of private utilities such as water, gas, electrical, and communications on your work site to prevent injury to workers and damages caused by a utility hit.


Ontario One Call can identify many utilities that are owned by utility companies and municipalities. Landshark Locates can mark and identify utility services that are not covered by Ontario One Call.  Utilities such as water, gas, electric, and communication lines may be run out to other buildings on site that are owned by the property owner.   These are considered private and will not be marked by an Ontario One Call Request.

The Ontario Regional Common Ground Alliance (ORCGA) is an organization promoting efficient and effective damage prevention for Ontario’s vital underground infrastructure. It has put togeather publicizations for the best practices to follow and some of the laws that mandate private and public locates to be completed prior to excavation.  Information on the following regulatory acts listed below is for information purpose only, and are not to be used as legal advice.

This comes right from the ORCGA best practices publication for damage prevention.

4-2: Privately Owned Facility Awareness (New 02/2008) Practice Statement

– Prior to excavating, the excavator must be aware that privately owned buried facilities may exist within the work area and should request the private facility owner (e.g. landowner) to locate his/her underground facilities. Practice Description – Privately owned underground facilities may not be marked by representatives of the public facility owners beyond the demarcation point of each facility (e.g. Private Property). The private facility owner is responsible for identifying the location of these buried facilities. Identification activities may include, but are not limited to: provision of maps, provision of engineering drawings from previous workings and/or retaining or authorizing the deployment of a private locator.

Ontario Regulation 213/92 (Construction Projects) Section 228, Occupational Health and Safety Act (Ontario Regional Common Ground Alliance Best Practices Version 8.0 – June 2014, page 54)

Other regulations that pertain to both private and public locates:

(b) each member that owns or operates underground infrastructure that may be affected by an excavation or dig has properly provided locates for its affected underground infrastructure or has stated in writing that none of its underground infrastructure will be affected by the excavation or dig; and

(c) if locates are properly provided, the excavator has ensured that the locate markings on the ground do not conflict with the written information provided respecting the underground infrastructure. 2012, c. 4, s. 7 (2).

Technical Standards and Safety Act, 2000, Ontario Regulation 210/01, Oil and Gas Pipeline Systems

O. Reg. 22/04, s. 10 (3).
