Ministry of Energy 
The Ministry of Energy works with many partners inside and outside of government to develop the electricity generation, transmission, distribution and other energy-related facilities that help power the Ontario economy.  It's responsibility is to ensure that Ontario’s electricity needs are met in a sustainable manner.  Developing renewable energy sources and fostering a conservation-oriented culture are cornerstones of Ontario's balanced plan to provide clean and reliable energy.

The OEB regulates both the electricity and natural gas sectors of Ontario.  This includes licensing generators, transmitters, distributors and retailers. It is also responsible for setting just and reasonable rates for the regulated entities.

Independent Electricity System Operator (IESO)

The IESO manages Ontario's electricity system and operates the wholesale electricity market. It forecasts the demand for electricity and ensures there are available supplies to meet that demand. The IESO web site is a source for information regarding current and historical load levels for the province as well as load reduction warnings and appeals.  On January 1, 2015, the IESO merged with the Ontario Power Authority. The IESO now oversees conservation programs.

Electrical Safety Authority (ESA)

The Electrical Safety Authority (ESA) is responsible for public electrical safety in Ontario as designated by Ontario Regulation 89/99. The ESA operates as an Administrative Authority under the Electricity Act 1998 and an Administrative Agreement with the Ministry of Government Services. The ESA had little impact on distribution utilities until 2004 when regulations were passed to have ESA monitor and inspect utility activity. This has resulted in increased costs to develop standards and processes and undertake audits to meet ESA requirements.
