Before You Dig, Get A Locate!


Digging a garden? Building a fence? Planting a tree? Installing a walkway or light standard?

Never assume you know the location or depth of a cable. Call Ontario One Call before you dig!

To request a FREE underground cable locate, contact Ontario One Call:

Avoid danger!
Underground excavation accounts for more than 20 per cent of power line contacts, and the information you get from Ontario One Call can prevent not only costly repairs due to accidental cable dig-ins but it may also save your life.

If you are planning to dig, drill, blast, auger or drive stakes (including fence post spikes) into the ground, it is essential that you call Ontario One Call before you dig.

Ontario One Call will notify all its members who may have underground facilities near or at the proposed dig and arrange for FREE field locates, where appropriate. Please call at least five working days prior to digging to schedule this service. During the busy spring season additional notice may be required.

It's the Law!
Arranging to have underground utilities located before you dig is also the law; reference the Ontario Occupational Health and Safety Act Construction Projects section 228.
