Ontario One Call Is Now Ontario Dig Authority: What Contractors Need to Know
If you dig in Ontario, you know the name Ontario One Call. As of October 1, 2026, the organization is called Ontario Dig Authority. The name is new, but the job is the same: help people dig safely and avoid underground damage.
What changed
The name, the branding, and the website. Organizations that still use the old branding are expected to switch before the 2027 digging season. Expect to see both names for a while, so don't be thrown if a supplier, municipality, or client still says Ontario One Call.
What did not change
You still need to request a locate before you dig.
Utility owners still mark their own public lines.
Lines on private property are still the property owner's responsibility.
Digging without following the proper process can still lead to fines. Since May 2024, the authority can issue them.
What contractors should do now
Update your crew training, safety documents, and bookmarks with the new name.
Check the official site for current contact details and request steps.
Tell your clients, since many homeowners still search for the old name.
Keep your records of each locate request with your job file.
The part the name change doesn't cover: private lines
Whatever it's called, the public system marks public lines. It does not mark the water, fire, gas, electrical, or communication lines on private property. Those need a private utility locate, and that's where TraceIQ comes in.
