About Us

Ontario One Call acts as the 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. In addition to our contact centre, we are also responsible for public education, industry outreach, and compliance.

As a Public Safety Authority, Ontario One Call is focused on guiding construction, infrastructure and excavation industries towards creating efficiencies and improvements across the province. Ontario One Call is a not-for-profit governed by a Board of Directors representative of the underground infrastructure and excavation industries.
