Most Hydro One customers have already been transitioned to time-of-use electricity pricing. If you’ve received notice that your account has changed to time-of-use prices, log in to My Account at www.hydroone.com to review your electricity usage and put the power of time-of-use to work for you.
To learn more about Time-of-Use prices and how to make them work for you, visit 10 Smart Meter Lane or review our frequently asked questions.
