Call before you dig

ON1CALL logoBuilding a new deck or fence? Digging a garden? Putting in a new pool? Planting a tree?

Before you dig, call 1-800-400-2255 or visit to request utility locates.

Requesting locates before you start digging not only keeps you safe and helps prevent costly damages, it’s also the law.

Activities that require a locate include, but are not limited to:

  • Building decks and fences
  • Installing pools
  • Paving or laying driveways
  • Planting trees
  • Creating new gardens
  • Installing light standards

Now, throughout Ontario, ON1Call handles all required utility locates, including municipal, with one simple service.

Visit or call 1-800-400-2255 for more information or to request a locate today.

The locate request service does not replace the need for building and other permits for the same types of work. Permit requests are still administered by Building Services. Visit for more information.
