For the first time, Ontario is allowing the customer to opt-out of Time of Use electricity prices and choose Tiered Pricing instead. Depending on your household needs, usage, and times during the day when most electricity is being used, you could save some money. Starting November 1st, 2020, new winter TOU and Tiered prices apply, and TOU customers will resume paying TOU prices that are different at different times of the day.

Not everyone will benefit from tiered pricing. Not sure which is the right fit for you? Use the calculator to see if switching is the right choice.
