Ontario One Call is now operating as Ontario Dig Authority.

Better Service with new technology


Starting today, Ontario One Call transitioned to an upgraded phone system to serve you better. The current phone numbers remain unchanged.  

While you may notice a different voice and an updated phone menu when you call, be assured that you’re still reaching the same team dedicated to supporting you. 

Our Support Services team remains available 24/7 for assistance. Standard Locate requests continue to be submitted online at www.ontarioonecall.ca. For any questions or assistance, please email us at solutions@ontarioonecall.ca
