Disclaimer
The law requires you to contact all facility owners having plant in or near your work area.
Ontario One Call is doing a great job of simplifying this process for its member companies. However, not all public utilities are members.
Therefore, this section of our site has been developed to help you contact both member and non-members utility companies.
This list has been carefully researched, but may not be complete or entirely accurate. It is meant as a guide to help you, not as
the complete guide to utility companies in Ontario.
If you find any errors or omissions in this information please CONTACT US to let us know.
