The Ontario Regional Common Ground Alliance (ORCGA) is a Canadian organization focused on promoting damage prevention strategies for underground infrastructure in Ontario. It collaborates with various sectors to enhance public safety, protect the environment, and maintain service integrity by advocating for best practices in damage prevention.

ORCGA offers key services that include developing tools and services to prevent damage to underground utilities, raising awareness through educational initiatives, and supporting legislative efforts like the “One Call” legislation. This legislation requires excavators to contact a central service before digging to identify underground utilities. The organization works with over 460 member organizations from construction, utilities, and government sectors, helping them implement effective damage prevention practices.
