To ensure an adequate level of consumer protection in the energy markets, the Board developed codes of conduct for gas marketers and electricity retailers, and established a complaint resolution process for energy consumers. The Board also provides a broad range of information to energy consumers about electricity and natural gas in Ontario. The Board oversees the electricity market and ensures regulated gas and electricity monopoly utilities comply with Board decisions and orders.
