December 22, 2020 - To support Ontarians staying home during the rapidly evolving COVID-19 situation, the Government of Ontario is holding the price of electricity at 8.5 ¢/kWh for electricity used from January 1, 2021 until the end of the day on January 28, 2021. This fixed price will apply to customers on Time-of-Use (TOU) or Tiered pricing. Read the government’s news release from December 22, 2020, and our FAQ.

Accordingly, our bill calculator reflects the fixed 8.5 ¢/kWh price currently in effect.


Compare Time-of-Use to Tiered pricing

Residential and small business customers that pay Time-of-Use (TOU) electricity prices can choose to switch to Tiered prices. Find out more about switching from TOU to Tiered prices.

Power is personal. Depending on how much electricity you use and when you use it, one price plan may suit you better than the other. Use our calculator to see what your total bill would look like under both TOU and Tiered prices, taking into account the other rates charged by your electricity utility (Delivery and Regulatory) and the Ontario Electricity Rebate.

To switch from TOU to Tiered prices, you must notify your utility by completing a form (called an election form). You can get the election form on your utility’s website or by contacting them.


  • Get your utility bill, or several months of bills. To use the calculator most effectively, you’ll want to know how much electricity you use and when you use it. You can find this information on the Electricity line of your bills or contact your utility for more detailed information about your electricity use.
  • Remember, your monthly use and usage pattern may be different in the winter season than it is in the summer season. Keep in mind the effect of COVID-19 on your electricity use (for instance, you may be working from home when you normally wouldn’t be).


See how your bill might look on an energy contract

Compare your current bill from your local utility with what to expect if you sign an energy contract with an energy retailer (also called an electricity retailer or a natural gas marketer). The bill calculator uses the regulated rates for each utility in Ontario. You can enter the contract price offered by the energy retailer to compare.
