Power is personal

Residential and small business customers can choose to switch between Time-of-Use, Ultra-Low Overnight and Tiered prices. Whatever plan you choose, one thing remains certain: the less electricity you use, the less you pay. Switching price plans will not affect your eligibility for the Ontario Electricity Rebate or other government programs like the Ontario Electricity Support Program.

Considering a switch? Learn more about price plans

If you don’t want to switch your price plan, you don’t need to do anything. You will stay on your current price plan. If you do want to switch to a different price plan, submit a request to change your plan.

You might qualify for the Ontario Electricity Support Program

You could get a monthly, on-bill credit of $35 or more. The Government of Ontario has changed eligibility for the Ontario Electricity Support Program (OESP) program, so more Ontarians now qualify. The credit amount depends on the number of people living in the home and the combined annual household after-tax income.  

Beware of energy scams: Home energy assessments, audits, inspections and home visits are not required to apply for the OESP.   Apply now or learn more at
