There are three time-of-use price periods:
- Off-peak is when demand for electricity is lowest; it costs 8.7/kWh.
- Mid-peak is when demand for electricity is moderate; it costs 13.2/kWh.
- On-peak is when demand is highest; it costs 18.0/kWh.
People use electricity differently throughout the year. The Ontario Energy Board has therefore created two sets of peak prices, which apply only to weekdays. Electricity is at its cheapest price on weekends and holidays all day throughout the year.

May 1 – October 31
In Summer, electricity use peaks during the hottest part of the afternoon, when air conditioners are running on high. On-peak hours are mid-day.
November 1 – April 30
In Winter, less daylight means electricity use peaks twice: once in the morning when people wake up and turn on their lights and appliances, then again when people get home from work. There are two sets of on-peak hours to reflect this.
