Ontario One Call is Now Ontario Dig Authority

As of October 1, 2026, Ontario One Call has a new name: Ontario Dig Authority.

While the name and brand have changed, its services, operations and responsibilities remain the same. Ontario Dig Authority continues to connect anyone planning to dig with buried infrastructure owners so underground utilities can be located before excavation begins.

If you're planning a project that involves digging; whether you're planting a tree, building a fence or deck, landscaping or completing a larger excavation - you must request a locate before you dig.

Locates are free and help protect you, your property and the underground infrastructure we all rely on.
