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.

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.
