The OEB has issued a letter summarizing the outcomes of its initial pilot on intervenor categorization and required collaboration (Item #3 of the OEB’s 10‑Point Action Plan). Feedback from participating parties indicates that coordinated participation can reduce duplicative interrogatories and support a more efficient adjudicative process. Building on these lessons, the OEB will undertake a second pilot as part of Enbridge Gas’s 2027–2030 DSM Proceeding (EB‑2025‑0295). Further details will be provided in Procedural Order No. 1.
