Restructuring
Ontario Hydro was restructured on April 1, 1999 into five separate entities: Ontario Power Generation, the Ontario Hydro Services Company, the Independent Electricity System Operator (originally named the Independent Electricity Market Operator), the Electrical Safety Authority, and Ontario Electricity Financial Corporation.
On May 1, 2000 the Ontario Hydro Services Company was renamed Hydro One Incorporated and reorganized as a holding company with four subsidiaries:
- Hydro One Networks Inc.
- Hydro One Remote Communities Inc.
- Hydro One Telecom Inc.
- Hydro One Brampton.
Between 1998 to 2000, Hydro One acquired 88 municipal electrical utilities. Numerous local/municipal distribution companies were also consolidated during this time.
In May 2002 the provincial government went ahead with the launch of an open electricity market, even though generating and distribution remained under control of the government.
Effective December 8, 2006, President and CEO Tom Parkinson's resignation was accepted . His resignation was prompted by a controversy surrounding use of company property and improper processing of personal expenses uncovered by the Ontario Auditor General.
Hydro One also owns the distribution Utility for the city of Brampton Ontario. This is another Subsidiary known as Hydro One Brampton. This subsidiary operates separately from the main Hydro One corporation and operates only in the city of Brampton.
