Regulatory Documents

Legislative Assembly of Ontario Building

As a Local Distribution Company, London Hydro is regulated by the Ontario Energy Board (OEB) a crown corporation that is responsible for overseeing the Province’s electricity and natural gas sectors and all of its participants. London Hydro’s rate applications must be approved through a complex hearing process from the OEB. The OEB also sets the prices for Regulated Price Plan time-of-use electricity rates and approves the rates for distribution/delivery and transmission. In short, they are the regulatory policy makers and it is our job to inform you on our regulatory activities.

This page contains important information on any filings, regulatory proceedings or other matters relating to our regulator.
