Call Before You Dig

Are you thinking of digging as part of a project or home improvement (such as building a fence, flower bed, deck, etc)? Contact Ontario One Call at 1-800-400-2255 before you dig. It is the law. Ontario One Call is a call centre that receives dig locate requests to make sure homeowners, diggers and property owners are safe when digging.

Ontario One Call alerts the infrastructure owners of your digging plans and contact information. Infrastructure owners can then provide locates, drawing, and/or clearances, lowering the risk of property damage, lost of utilities, injury, and penalties/fines.

Locates can be markings on the ground or a statement/email from the infrastructure owner that its buried infrastructure will not be affected by the digging.

You can visit the Ontario One Call website to learn more about their services.
