Ontario One Call (OOC) is a Public Safety Administrative Authority; protecting Ontario by enabling safe digging. At OOC, public safety is at the heart of everything we do.

Since 2012, in Ontario, it's the law that any party planning to dig must contact OOC before they dig. OOC connects people planning to dig with the owners of underground pipes, cables, and other infrastructure to help prevent costly damages, service disruptions, and safety hazards. We also regulate an efficient locate system, foster industry wide collaboration, and promote safe, timely excavation across Ontario.

OOC is governed by a diverse Board of Directors, with experienced leaders representing underground infrastructure owners, excavators, ministry appointees and others dedicated to protecting Ontarians. Together, we work to shape a safer Ontario through collaboration, regulation, and education.

Safe Excavation starts with us.
