Electricity prices change in response to supply and demand. Here is an overview of pricing in Ontario's electricity market, including access to historical information.
Residential and small business customers that pay TOU electricity prices can choose to switch to tiered pricing. With tiered prices, customers pay a set rate for electricity up to a certain level of consumption. The rate increases for all additional electricity used when consumption by these customers exceeds that threshold. Learn more about electricity pricing in Ontario.
Historical TOU prices can be found on the OEB website.
