Effective November 1, 2026 Ontario began its winter electricity pricing schedule with modest declines in time of use rates, but at the same time the provincial rebate that reduces consumer bills will shrink sharply. The Ontario Energy Board set lower winter time of use and tiered rates for households, small businesses and farms, while the Ontario Electricity Rebate moved to 15.7 percent from 23.5 percent, a change that will blunt much of the immediate cash relief consumers might expect from the lower kilowatt hour prices.
What is changing on bills this winter
The Ontario Energy Board announced the new Regulated Price Plan schedules in mid October and specified that the winter time of use pricing and other rate changes take effect on November 1. Under the new numbers off peak, mid peak and on peak time of use prices are lower year over year. The board also adjusted tiered thresholds for winter months and reactivated winter hours that run through April 30, 2027.
At the same time, the provincial rebate that appears as a percentage reduction on a customer bill will be lowered to 15.7 percent. The OEB estimates the net effect for a typical home using about 700 kilowatt hours a month will be a rebate worth roughly twenty three dollars per month this winter, down from about thirty six dollars under last winter's rebate level.
Why lower rates but a smaller rebate
The OEB frames the change as a technical result of lower year over year supply cost forecasts for the provincial electricity system. When expected wholesale costs fall the regulator reduces the per kilowatt hour RPP prices it sets. Regulators and the provincial government say those lower price forecasts mean the rebate program can be reduced while leaving overall bill pressure roughly consistent with recent years.
Analysts and some consumer advocates note the arithmetic obscures distributional effects. A smaller percentage rebate reduces the cushioning effect of the OER on larger bills, and customers with high winter consumption, including those who heat with electric resistance systems, may see less benefit. At the same time customers who can shift usage into off peak windows will benefit proportionally more from the lower time of use prices.
Political and economic stakes
The rebate has been a visible policy lever in Ontario electricity politics since its introduction, and changes to it are politically sensitive. The cut to the OER reduces direct provincial support on bills at a time when energy costs figure strongly in household budgets, and may influence perceptions of the provincial government ahead of future fiscal milestones.
From a business perspective the changes matter for small enterprises that face electricity as a non discretionary operating cost. Lower per kilowatt hour prices reduce marginal consumption costs, but the smaller rebate reduces an across the board discount that many small retailers and farms rely on. Businesses with flexible load and the ability to shift operations to off peak windows will gain more than those with fixed daytime loads.
What consumers and businesses can do
For households and small firms the regulator and utilities are encouraging demand shifting to off peak hours where prices are lowest. Simple actions such as running major appliances in the evening or on weekends and adjusting thermostats when possible can lower bills. The OEB also highlights existing support programs for low income households and the winter disconnection ban which runs from November 15 through April 30, designed to prevent winter shut offs for residential customers.
Longer term, the rebate reduction increases the relative financial case for investments in energy efficiency and distributed generation such as rooftop solar and heat pumps for space heating. Industry and clean energy groups note that smaller bill rebates mean the upfront economics of efficiency and electrification projects improve modestly, a dynamic that could accelerate demand for those products and services.
Why this matters beyond Ontario
Ontario is Canada’s largest provincial electricity market and its pricing and policy choices influence generators, distributors and equipment suppliers across the country. Changes to the OER also feed conversations in other provinces about how governments share the cost of energy with ratepayers, and how short term affordability measures interact with long term system planning such as new generation investments or import contracts to manage winter supply.
The OEB decision underlines a recurring policy trade off in energy management, between lower per unit prices calibrated to wholesale forecasts and targeted assistance that smooths bills for households. For businesses and consumers the immediate task is to understand the math on their own bills, and to consider whether behavior changes or investments in efficiency could protect them from future volatility.
As the winter pricing schedule remains in place until April 30, 2027 the combination of lower time of use prices and a smaller rebate will be reflected in monthly bills over the coming months, giving households and small businesses time to adapt their consumption patterns and consider longer term investments to reduce electricity exposure.
