Utility performance and monitoring

Yearbooks provide a detailed look at the entire natural gas and electricity distribution systems in Ontario for a specific year, starting with 2005.

They are packed with data – ranging from financials and operating information to reliability and customer service statistics. You can find out the following, and more:

  • The frequency of interruptions to electricity supply by a variety of causes, including adverse weather and scheduled outages
  • The total number of Ontario natural gas customers and the total volume of gas they used in 2015
  • Operating and maintenance expenses for electricity and gas utilities this year, and in previous years
  • Financial data for each of the province’s electricity and natural gas utilities
  • The number of days electricity and natural gas utilities take to reconnect a customer
  • And unusual events like, the one-time effect the December, 2013 ice storm had on electricity distribution reliability

  • 2016 (xlsx)
  • 2013–2016 disconnection and late payment data by utility (pdf) (Sep 27-17)

    • In relation to these figures it is important to note that with the passage of enabling legislation in February 2017, the OEB moved swiftly to ban the winter disconnection of homes by electricity utilities.

    • As well, the OEB is further reviewing policies and practices on disconnections and arrears payments as part of the Customer Service Rules review currently underway.  This includes the launch of an online survey at www.oeb.ca/customerservicesurvey to gather input from residential and small business consumers on these and other questions about customer service rules. Public input via the survey is a priority for the OEB CSR review and will be open until early November.
