Regulated standard
Green Button is part of Ontario’s energy plan, implemented consistently across participating utilities under O. Reg. 633/21.
A regulated initiative for Ontario utilities, account holders and third parties to share energy data in the Green Button standard, with the guidance and tools to put it to work.

Ontario Utility Green Button solutions are a regulated requirement under O. Reg. 633/21. More than fifty electricity and natural gas utilities are in scope, alongside water utilities that participate voluntarily.
Green Button gives account holders a simple, secure way to access their own energy information and to authorize trusted third parties to receive it, in one consistent standard across every participating utility.

Green Button Ontario supports the OEB Industry-Led Working Group, an open forum where distributors and stakeholders have collaborated since 2022, contributing thousands of volunteer hours to make Green Button work consistently across the province.
