Ontario Energy Board Announces Changes to Electricity Prices

The Ontario Energy Board (OEB) announced today that electricity prices under the Regulated Price Plan (RPP) for households, small business and farms will change as of November 1, 2025. Winter Time-of-Use (TOU) hours and the change in threshold for residential customers on Tiered pricing will also take effect.

Also, effective November 1, 2025, the Ontario government’s Ontario Electricity Rebate (OER) will change to 23.5%. The OER provides a rebate on the electricity bill of residential, small business and farm customers. For a typical residential customer^[1] who uses 700 kWh of electricity per month, the OER will decrease bills by about $36 each month.

Table 1 shows the TOU prices set by the OEB for November 1, 2025, and the hours to which those prices apply.

Winter TOU Price Periods	November 1, 2025 TOU Prices
Off-Peak Weekdays 7 p.m. – 7 a.m., all day weekends and holidays	9.8 ¢/kWh

On-Peak Weekdays 7 a.m. – 11 a.m. and 5 p.m. – 7 p.m.	20.3 ¢/kWh
