The vast majority of homes and small businesses in Ontario are billed for their electricity using time-of-use rates set by the Ontario Energy Board. Understanding how time-of-use rates work is a first step towards helping to manage your electricity costs. 

Time-of-use rates divide the day into three rate periods:

  • Off-peak, when demand for electricity is lowest. 
  • Mid-peak when demand for electricity is moderate.
  • On peak when demand for electricity is highest.

The rate you pay for electricity in each of these periods reflects the costs of supplying electricity at that time of day. When demand for electricity is lower, electricity is less expensive. More expensive sources of electricity are used when demand is higher, which in turn makes the price higher.

There is both a Winter and Summer schedule for Time-of-use pricing which are set by the Ontario Energy Board and are reviewed every 6 months. For additional information on time-of-use pricing and time periods, visit the Ontario Energy Board Web site.
