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 together 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.
