Beginning November 1, 2020, you can choose to switch from Time-of-Use (TOU) electricity prices to Tiered prices.

With TOU, the price you pay depends on when you use electricity. With Tiered prices, you can use a certain amount of electricity each month at a lower price. Once that limit is exceeded, a higher price applies.

If you want to continue paying TOU prices, no action is required.

About TOU prices

With TOU prices, the price depends on when you use electricity. People use electricity differently depending on the season, so the TOU price periods are different in the winter than they are in the summer.

About tiered prices

With Tiered prices, you can use a certain amount of electricity each month at a lower price. Once that limit (called a threshold) is exceeded, a higher price applies.

For residential customers, the threshold normally changes with the season to reflect changing usage patterns. For example, there are fewer hours of daylight in the winter and some customers use electric heating.

In the winter period (November 1 – April 30), the Tier threshold for residential customers is 1,000 kWh so that households can use more power at the lower price. In the summer period (May 1 – October 31), the Tier threshold for residential customers is 600 kWh.

For small business customers, the Tier threshold is 750 kWh all year round.

Tiered prices give you the flexibility to use electricity at any time of day at the same price, although that price will change if you exceed the threshold during the month.

Considering a switch

Consider the factors below to determine if the switch is right for you. Make sure you have some of your recent electricity bills handy as you go through the information below. 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).

Who's eligible to switch

  • The choice between TOU and Tiered prices is available to nearly all residential and small business customers that have smart meters and are billed on TOU. Some residential and small business customers are charged Tiered prices because their meters can't be used to bill TOU prices. They can't switch to TOU prices at this time.
  • If you live in a condominium or apartment that has its own individual meter and your bill comes from a company other than EPCOR, you are a customer of a unit sub-meter provider (USMP). Customers of USMPs also can't switch to Tiered prices. That decision can only be made for the building as a whole by the "master consumer," who is the person that retained a USMP for the property. In most cases, the master consumer is the property manager, landlord or condominium board.
  • Customers that are buying their electricity from an energy retailer pay the electricity price set out in their contract.  Once they have left their retail contract, they will have a choice between paying TOU or Tiered prices. For details about your energy contract, contact your energy retailer.

Switching to Tiered prices

Below, are the rules for switching to Tiered prices. These rules also apply if you later want to switch back to TOU prices.

  • Fill out the election form to notify us that you want to switch. You should have a recent electricity bill on hand when filling out the form, as you will need to provide your account number.
  • Submit your election form to EPCOR via email to or mail at:
    • EPCOR
      43 Stewart Road
      Collingwood, Ontario L9Y 4M7  

  • We will notify you within 10 business days of when you can expect to start being billed on Tiered prices or why your election form can't be processed (for instance, if you're not authorized to make changes to the account or the account can't be verified). 
  • A switch from TOU to Tiered prices can only take effect at the start of a billing period. You are billed for a 30-day period, and the start and end dates are identified on your electricity bill.
  • After you submit your election form, we will start charging you Tiered prices as of your next billing period, provided we receive the form at least 10 business days before that billing period starts and there are no issues with your form (see above).
  • If you have chosen to switch to Tiered prices and later decide you want to go back to TOU prices, you can do so at any time. The process described above applies.
