Call Before You Dig – Locates
Everyone is required to have underground utilities located and marked before doing any kind of digging.
Anyone needing to request locates for underground infrastructure contact Ontario One Call.
It is important to find out what is underground before starting a project because damaging buried utilities is dangerous. If a utility is damaged, it could be harmful to the person digging and essential services such as electricity, telephone or water could be interrupted.
When to Request Locates
A locate must be requested at most 30 calendar days prior to the expected excavation time. It may take up to five business days to complete a locate request and mark York Region utilities.
Homeowners require a locate before digging for any reason. For example:
- Putting in a new pool
- Installing a sprinkler system
- Digging holes for a deck or fence
- Planting a tree or creating a new garden
- Landscaping projects
Contractors require a locate for all of the activities above and before starting projects such as:
- Road repairs
- Utility repairs and installations
- Putting in or widening a driveway
