Click or Call before you dig
Whether you're building on a jobsite or in your backyard, before you dig, know what's below. Contact your One-Call Centre to have your underground utilities located and marked free of charge.
A Crossing can mean constructing or installing a temporary or permanent structure across; on, along or under a facility or pipeline right-of-way, or it can mean operating or transporting heavy equipment or machinery over or across the pipeline right-of-way or facility site. These activities have the potential to damage the pipeline, so you must apply, and if you receive permission, contact your local One-Call Centre when planning your work.
