Ontario electricity prices and winter periods change November 1
New RPP prices take effect alongside a 15.7% rebate and winter tier threshold. Lower electricity prices do not by themselves establish a lower total bill.

New Ontario Regulated Price Plan electricity prices take effect November 1, alongside winter time-of-use hours and the seasonal residential tier threshold. The Ontario Energy Board announced the changes on October 16. The effective date is new today; the announcement itself is not a newly issued November 1 decision.
The winter time-of-use prices are 9.1 Canadian cents per kilowatt-hour off-peak, 14.6 cents mid-peak and 18.9 cents on-peak. Weekday on-peak periods are 7 a.m. to 11 a.m. and 5 p.m. to 7 p.m.; mid-peak is 11 a.m. to 5 p.m. Off-peak covers weekday nights, weekends and holidays. These are electricity prices, not the entire delivered bill.
Under the Ultra-Low Overnight plan, the overnight price is 3.7 cents per kilowatt-hour from 11 p.m. to 7 a.m. every day. Its weekday 4 p.m. to 9 p.m. on-peak price is 37.7 cents. The low overnight figure therefore should not be presented as an all-day rate or proof that the plan is cheapest for every household.
For residential customers on tiered pricing, the first 1,000 kilowatt-hours per month cost 11.2 cents per kilowatt-hour and usage above that threshold costs 13.2 cents. Non-residential tiered customers retain a 750-kilowatt-hour threshold. The winter residential threshold provides 400 more kilowatt-hours at the lower price than the summer threshold.
The Ontario Electricity Rebate also changes to 15.7% from November 1. The OEB says RPP electricity prices are decreasing year over year, allowing a reduction in the rebate, while the overall rate of customer-bill increases remains consistent with previous years. A lower electricity price alone does not establish a lower total bill. The OEB’s example of about CAD23 a month describes the rebate for a typical 700-kilowatt-hour customer, not a new CAD23 saving versus the previous bill.
Residential, small-business and farm customers can choose among time-of-use, tiered and Ultra-Low Overnight pricing where eligible. Individual bill effects vary with usage and the serving utility. The OEB separately lists a November 15 to April 30 winter residential non-payment disconnection ban; that protection does not begin on the November 1 tariff-change date.
