Understanding current rates and how they're set.

Rates as of January 1, 2025

Effective January 1, 2025, following approval from the Ontario Energy Board (OEB), we’ve updated our Delivery Charges. The OEB also announced that as of January 1, 2025, changes to Regulatory Charges are in effect.

Electricity Rates

Eligible customers on the Regulated Price Plan (RPP) have the option to choose between Time-of-Use (TOU), Ultra-Low Overnight (ULO) and Tiered price plans. Visit our Customer Choice page to learn more and determine which plan works best for you.

As of November 1, the OEB moved to winter time periods. TOU rates are listed in the following table, which also indicates the hours to which these rates apply.

Winter price periods from November 1, 2024 to April 30, 2025

As of November 1, the OEB moved to winter tier thresholds. The Tier threshold for small business customers is 750 kWh all year round.

Winter pricing tiers from November 1, 2024 to April 30, 2025

Price tier Description Price
Tier 1 Non-residential customers: for electricity used up to 750 kWh/month 9.3¢ per kWh
Tier 2 Non-residential customers: for electricity used above 750 kWh/month 11.0¢ per kWh

These rates cover the cost of electricity purchased on your behalf. Toronto Hydro collects this cost from you, without mark-up, and pays it directly to our suppliers.

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, 2025.

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.

Regulatory Charges

The OEB announced an update to Regulatory Charges, effective January 1, 2025. Regulatory Charges cover the costs of administering the wholesale electricity system and maintaining the reliability of the provincial grid.

Refer to the following table for current charges. For an explanation of the charge, please refer to the list of terms and definitions at the bottom of the page.

Regulatory Charges

Charge name Rate
Capacity Based Recovery (applicable for Class B customers) $0.0004 per kWh
Standard Supply Service – Administration (if applicable) $0.25 per 30 days
Wholesale Market Service $0.0056 per kWh

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 Finance website or call the HST hotline at 1-800-337-7222.

The provincial government announced a change to the OER from 19.3% to 13.1%, effective November 1, 2024. The Ontario government introduced the OER as an expanded rebate providing bill relief that is applied to customer bills, largely offsetting price changes on the electricity line. The rebate is 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 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.

If you have any questions, please visit our contact page to reach us by phone or using our online contact form.
