It’s free, required by law, and one of the simplest ways to protect yourself and those around you.
Dig informed. Keep Ontario connected and safe.

Request your locate before you dig at OntarioOneCall.ca.

Always contact Ontario One Call before you dig. Locate requests are free and required by law.

Whether you are a contractor or a homeowner, taking a few minutes to request a locate helps protect workers, families, and the essential services we all rely on.

Dig safe. Plan ahead. Protect Ontario.
