For projects small and big... call or click before you dig.

From planting rose bushes to building a new fence or even when installing a dock, first call or click to get a FREE underground utility locate. You will be provided with a response from various utilities indicating whether or not there is underground infrastructure within your requested dig area so you can work safely.

Digging without a locate not only puts your safety at risk, but could also make you liable for repair costs if you or your contractor damage any underground infrastructure, such as: electricity cables, gas pipes, water and sewer or communication cables.

This service is free, it's easy and it's the law.

Here's how to request an Underground Cable Locate

1. Submit an e-ticket at or contact Ontario One Call at 1-800-400-2255. The service is available 24/7.

2. To help you plan your work, Ontario One Call will need at least five business days' notice. A service representative will clearly mark where cables run through your property and provide you with a locate sheet that includes a diagram of where your underground facilities are located.

3. If markings are not required, you will still receive a response from the utility to indicate that your work area is clear.

4. Once you have your locates it is important that you practice safe digging and follow any additional instructions provided by each utility.

5. Visit Ontario One Call or Dig Safe for more information.
