Dear Stakeholders,
As of November 1, 2026, Ontario Regulation 34/26, Continuation After Expiry of Validity Period, is in effect.
This optional pathway allows eligible excavators to continue digging after their locate validity period expires, provided all prescribed requirements remain satisfied.
The maximum period is 180 days from when the last locate document was provided, including the original locate validity period. It is not an additional 180 days after expiry.
Before using Continuing to Dig
Confirm that your site meets the requirements, including:
- No transmission infrastructure at the dig site.
- Excavation at least one metre below the lowest identified underground infrastructure.
- Continued care and control of the site by the excavator.
You must submit a statement and two undertakings through Ontario Dig Authority’s web portal between 15 and 10 days before your most recent locate expires. You must maintain access for affected underground infrastructure owners to conduct inspections and keep the required locate and confirmation documents at the site.
If the required conditions are no longer met, stop excavation, notify Ontario Dig Authority and obtain new locates before continuing.

Continuing to Dig is optional. There is no requirement to begin using it on November 1. Take the time you need to understand the requirements and determine whether it suits your projects and internal processes. If your projects do not qualify, or if you choose not to use the pathway, you can request relocates and new locates as usual.
