Call Before You Dig

Before starting any work in the yard, or around your house, call us for the location of underground power lines, especially if you're planning to use auguring or trenching equipment. Our service locators will confirm and mark Toronto Hydro-Electric System owned underground electrical cables.

WHAT YOU SHOULD KNOW

You should know that, under the Occupational Health and Safety Act (section 228), it is the owner's responsibility to have all underground services marked for the safety of contracted service workers prior to having any excavation work done on private property.
