Ontario Dig Authority Ontario One Call is now operating as Ontario Dig Authority. Submit your request online before every dig.

We're the public safety authority connecting anyone planning to dig with the infrastructure owners required to provide locates. ON1Call became a not-for-profit corporation August 11, 2011. The Ontario Underground Infrastructure Notification System Act, 2012, was passed in June 2012, thereby making ON1Call a Statutory Corporation. Under the Act, ON1Call is also responsible for ensuring compliance with the Act’s regulations. The bill stipulates that all owners of underground infrastructure must register their infrastructure with ON1Call in order for us to provide accurate nitification services to protect assets, people and property. The goal is to eliminate injuries and reduce costs due to interference with infrastructure. ON1Call is proud to provide best in class service to over 700 members and the excavating community.

Submitting a locate request is the first step.

Before you dig, you must wait for all notified infrastructure owners to respond and review your complete locate package.

Do not begin digging until you have received and reviewed all required responses.

This Fire Prevention Week, let’s remember: fire risks aren’t just inside your home; they can start underground too.

Damaging a buried gas line while digging can cause leaks, explosions, and serious emergencies.

Protect yourself, your family, and your community by submitting a free locate request before you dig.
