Ontario Dig Authority Rebranding Information Guide
On October 1, 2026, Ontario One Call rebranded to Ontario Dig Authority.
This change reflects the evolution of our organization and the role we play in supporting damage prevention across Ontario. While our name and brand have changed, our operations, services, responsibilities, and stakeholder requirements remain unchanged.
Stakeholders should continue to use our services as they do today.

Available Assets
Download the new Ontario Dig Authority brand assets and brand guidelines to support your transition planning.
Beginning October 1, 2026, all new materials should use the Ontario Dig Authority brand. Existing social media posts, printed materials, presentations, and other previously published content do not need to be updated or removed. This is not a retroactive rebrand.
During the Asset Transition Period from November 2026 through March 2027, organizations should update active digital assets, such as websites and online resources, and incorporate the new brand into new materials as they are created. Existing printed inventory can continue to be used until it is naturally replaced.
