Ontario One Call Information

Ontario Dig Authority, formerly known as Ontario One Call, regulates Ontario's excavating community, promotes dig safe and click before you dig messaging, and provides a locate request system that connects those planning to dig with buried infrastructure owners. In 2012, the Ontario Underground Infrastructure Notification System Act was passed, which stipulates that by law, anyone in the province of Ontario must contact Ontario Dig Authority before they dig. Though Ontario Dig Authority does not physically mark the lines, pipes, or cables, we relay all dig information to the buried infrastructure owners so they can mark (locate) based on the request you submit. Buried infrastructure owners will then deliver locates. Locates minimize the risk of infrastructure damage, loss of service, and injury.
