If you dig in Ontario, whether it's planting a tree or building a fence, you must contact Ontario One Call.

Our Mission

We protect Ontario communities from the loss of service and harm caused by damages to underground infrastructure by educating the public on the need to Call Before You Dig.

We provide a locate request process that is reliable, timely and easy to use.


Who We Are

Established in 1996, Ontario One Call is a not-for-profit organization that acts as a communications link between buried infrastructure owners (our members) and individuals who are planning to dig in the province of Ontario. 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 One Call before they dig.

Though Ontario One Call 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, by marking the property with paint and/or sending paperwork directly to you. Locates minimize the risk of infrastructure damage, loss of service, and injury.
