We energize life for customers and communities across Ontario by delivering electricity safely and reliably to homes and businesses in Ontario. The Ontario Energy Board (OEB) approved 2021 delivery rates that are reflected on the Delivery line on your bill. The new rates will apply to your usage starting on January 1, 2021.

Energy tools

Residential, seasonal and general service energy billed customers will see a decrease to their delivery rates. The amount your bill will change depends on your rate class, how much electricity you use, the changes to Electricity and the reduced Ontario Electricity Rebate. Please see the bill impact table below for details.

The Delivery line is the only part of the bill that's from us. Although we collect the other line items on your bill, but they are simply passed on to other organizations (such as IESO) without any markup. 

Here’s a summary of the other changes that you’ll see on your bill:

1) The Electricity line – The Government of Ontario is providing a COVID-19 Recovery Rate for households and small businesses that pay Time-of-Use (TOU) or Tiered pricing. Customers will be billed a new flat price of 8.5 cents per kWh, 24 hours a day, seven days a week starting on January 1, 2021 until February 22, 2021. To see if you’re billed TOU or Tiered prices, please see page two of your bill (next to the Electricity line). Click here to see where this information lies on your bill.

2) The Ontario Electricity Rebate – The Government of Ontario reduced the amount of the rebate to 21.2% (from 33.2%) of the bill before HST, effective January 1, 2021.

For customers who pay the spot market price or have a contract with a retailer:

3) Global Adjustment (GA) line – As part of the commitment to reduce electricity costs for Ontario households and businesses, the Government of Ontario will fund a portion of GA associated with the costs of non-hydro renewable energy contracts (i.e., wind, solar and bioenergy). This will reduce the cost of electricity. The amount customers will save depends on how much electricity they use.
Note: The amount customers will save will be slightly offset by the recovery of the GA deferral.

1Residential medium density and low density customers have Distribution Rate Protection, which is a cap of $36.86 on the monthly service charge and distribution volume charge.

2Residential customers with a low density rate class get additional rate protection under the Rural and Remote Rate Protection program (currently at $60.50 per month). This credit is rolled up into the Delivery line and doesn’t display separately on the bill.

3The bill impacts for General Service Demand, General Service Urban Demand, Distributed Generation and Sub Transmission have been calculated based on the weighted average hourly spot price (WAHSP). Customers billed on WAHSP will pay a reduced Global Adjustment rate. Bill impacts for all other rate classes have been calculated using the flat electricity price of 8.5 cents per kWh.
