Business rates and charges

Understanding current rates and how they're set.

Rates as of May 1, 2022

The Ontario Energy Board (OEB) announced no changes to the Time-of-Use (TOU) and Tiered electricity rates for May 1. However, May 1 marks the start of the summer TOU hours and Tier thresholds. This change impacts all customers under the Regulated Price Plan (RPP).

In addition, the Smart Metering Entity charge (part of the Delivery Charge) is being reduced from $0.56 to $0.42 per 30 days effective May 1, 2022. This is only applicable to small business customers.

These rates will automatically be applied to your bill — no customer action is required.

Summer Tiered pricing per 30 days from May 1, 2022 to October 31, 2022

Tier 1Non-residential customers: for electricity used up to 750 kWh/month9.8¢ per kWh

Most General Service customers with a monthly demand greater than 50 kW – who don’t have a contract with a retailer – pay the wholesale electricity price and Global Adjustment electricity charge. Toronto Hydro collects both charges from you, without mark-up, on behalf of the Independent Electricity System Operator (IESO).

Customers with interval meters are charged the Hourly Ontario Energy Price (HOEP), which is the hourly price that’s charged to Toronto Hydro, for their electricity consumption. Customers without interval meters are charged a weighted average hourly price based on consumption patterns of similar consumers. Customers may also choose a contract offered by a licensed electricity retailer.

You may choose to purchase your electricity from another company by entering a contract with a licensed electricity retailer. Your contract specifies a fixed electricity price for a set number of years. Unlike Toronto Hydro's rates, the fixed price is not regulated by the OEB. Please visit the OEB's Retail Energy Contracts page for more details.

Delivery Charges

Toronto Hydro received approval from the OEB to implement changes to its Delivery Charges, effective January 1, 2022.

Delivery Charges cover the cost of delivering electricity from the generator to Toronto Hydro, and then to your home or business. This includes costs to build and maintain transmission and distribution lines, towers and poles, and to operate provincial and local electricity systems.

Additional charges

Effective July 1, 2010, a Harmonized Sales Tax (HST) of 13% is applied to electricity bills. The implementation of HST is mandated by the Province of Ontario. For information on HST, please visit the Ontario Ministry of Revenue or call the HST hotline at 1-800-337-7222.

The provincial government announced a decrease in the OER from 18.9% to 17.0%, effective November 1, 2021 . The Ontario government introduced the OER as an expanded rebate providing bill relief that will be applied to customer bills, largely offsetting price changes on the electricity line. The rebate will be applied to bills for most residential consumers, long-term care homes, farms and many small businesses.

These charges are applied to current customers who have an unmetered electric water heater billed by Toronto Hydro on a flat rate basis. Toronto Hydro no longer offers this flat rate billing option for new customers.

As of May 1, 2002, flat rate (unmetered) water heater energy usage is billed on an estimated average daily kWh basis. Your estimated usage is determined by the size of your water heater, the wattage of the water heater electric elements and on the number of days in the billing period. If you have an unmetered electric water heater, you’re being billed on the higher tiered rate of the Regulated Price Plan.
