Ontario One Call is aware of recent changes to publicly available mapping information that have resulted in some websites displaying an alternate name for Lake Ontario. We have reviewed our systems and can confirm that Ontario One Call users and the Locate Request process are not impacted. Locate requests can continue to be submitted as usual.

We will continue to monitor the information displayed through our systems and take the necessary steps to ensure Lake Ontario is correctly identified for users. Accurate location information helps excavators clearly identify where work is taking place and supports a safe, effective locate request process.

Ontario One Call remains committed to providing reliable services that help Ontarians dig safely.

When Is It Safe to Dig? Check Your Locate Status

Before you dig, make sure your locate package is complete and all notified infrastructure owners have responded.

Here are a few common locate status definitions:
▪️Notification Sent: The utility has been notified of your request.
▪️Sent to Locator: Your request has been sent to the locate team, but there is no update yet.
▪️Cleared: No physical locate is required. You should receive clearance paperwork.
▪️Completed: The dig area has been marked with paint or flags, and you should receive paperwork with instructions.

Do not begin digging until you have received and reviewed all required responses.

Check your locate status anytime at OntarioOneCall.ca.

Was your locate request suspended?

A suspended locate request means the Ontario One Call system detected an issue that needs to be reviewed before the request can move forward.

This can happen when information is missing, unclear, or may need to be corrected.

What happens next?
▪️Your request is reviewed by an Ontario One Call agent
▪️ You may receive a clarification email asking for more details
▪️ Once reviewed, your request will either be processed or you will be advised of any required changes

If your request is suspended, check your email and respond as soon as possible so your request can get back on track.

Suspensions help make sure the information is accurate before the locate process continues.
