Residential Electricity Rates

If you’re a residential or small business customer that pays Time-of-Use (TOU) electricity prices, you can choose to switch to Tiered* prices. 

If you want to continue paying TOU prices, no action is required. If you would like to learn more about your pricing options, visit

To switch from TOU to Tiered prices, you can notify us by completing an election form or by contacting us at (519) 661-5503, Monday through Friday, 8:30 am - 4:00 pm.

You may wish to continue paying TOU prices for your electricity. In that case, no action is required.

About TOU Pricing

With TOU prices, the price depends on when you use electricity. You can help manage your electricity costs by shifting your usage to lower price periods when possible.

There are three TOU periods:

  • Off-peak: When demand for electricity is lowest. Ontario households use most of their electricity – nearly two thirds of it – during off-peak hours.
  • Mid-peak: When demand for electricity is moderate. These periods are during the daytime, but not the busiest times of day.
  • On-peak: When demand for electricity is generally higher. These are the busier times of day - generally when people are cooking, starting up their computers and running heaters or air conditioners.

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 Pricing

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.

Ontario Electricity Rebate per bill (18.9%)

*In calculating your bill, your consumption amount will be adjusted to account for heat loss. When electricity is delivered over a power line, it is normal for a small amount of power to be consumed or lost as heat. Equipment such as wires and transformers consume power before it gets to your home or business. The adjustment factor accounts for these losses.

** Monthly Administration charge applies to non-retailer affiliated customers only.

***Adjustment Factor Charge is kWh x 0.0315 x Electricity Rate. For Example: 200kWh x 0.0315 Adjustment Factor x Electricity Rate = 6.3 kWh x $0.128/kWh = $0.806.


****Volumetric Rate Riders include the following: Rate Rider for Disposition of Deferral/Variance Accounts $(0.0005); Rate Rider for Disposition of Lost Revenue Adjustment Mechanism Variance Account $0.0005; Rate Rider for Disposition of Capacity Based Recovery Account $(0.0002)


***Volumetric Rate Riders would include the Rate Rider for Disposition of Global Adjustment of $0.0045/kWh for those customers who do not pay Regulated Price Plan prices.
