What is the average monthly hydro bill in Ontario?

As of my knowledge cutoff in September 2021, the average monthly hydro bill in Ontario for residential customers was approximately $150, according to the Ontario Energy Board. However, please note that electricity rates can vary depending on factors such as the energy provider, local distribution company, time of use, and electricity consumption patterns. For the most up-to-date information, it's best to contact your local electricity provider or visit the Ontario Energy Board's website.
