IMPORTANT: Effective June 1, 2020, the Government of Ontario introduced a new fixed electricity price for Time-of-use customers of 12.8 ¢/kWh for all hours of the day, 7 days a week.
There are three time-of-use price periods:
- Off-peak is when demand for electricity is lowest;
- Mid-peak is when demand for electricity is moderate;
- On-peak is when demand is highest.
Time-of-Use prices reflect the fact that the cost to provide electricity changes throughout the day. When demand is low, less expensive sources of electricity are used. When demand rises, more expensive forms of electricity production are called upon, making prices higher. The price periods are a blending of forecast wholesale costs with the anticipated global adjustment.
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.

* Effective November 1, 2019, with changes in legislation, customers will see an increase in the prices on the Electricity line of their bills as prices will once again closely reflect the forecast cost of electricity supply. The government added an expanded rebate providing bill relief (the Ontario Electricity Rebate) will be applied to customers’ bills and reduce the pre-HST amount of the bill. The rebate will largely offset the price changes on the Electricity line. For more information, visit the Ontario government website
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.
