Installing a fence? Paving your driveway? Digging anywhere on your property? Then you will require a locate.

A locate will show where any underground hydro lines may be so injury to persons or damage to equipment may be avoided. Greater Sudbury Hydro provides free underground cable locates during normal business hours.

It’s the law to request a locate before digging. Not doing so could result in serious injury and/or damage to  distribution system equipment. It’s for your safety and those around you.

To request a locate of underground cables on your property contact Ontario One Call:
