Having Trouble Paying Your Electricity Bill?

Posted October 28th, 2022

Contact your utility right away to find out about payment options.  Payment arrangements with Grimsby Power can help you avoid late payment charges and potential disconnection of service.

Eligible customers can access bill payment support programs such as the Low-income Energy Assistance Program (LEAP) and the Ontario Electricity Support Program (OESP). And, to protect low-income customers, there are also special customer service rules that include allowing more time to pay overdue amounts under an arrears payment plan. Learn more about these programs and customer service rules at OEB.ca/billhelp

IMPORTANT: Electricity and natural gas distributors cannot disconnect residential customers for non-payment during the winter disconnection ban period of November 15 to April 30. However, because they can continue to charge late payment fees on past due amounts, it is important you remain in contact with your utility during this period and explore payment options that may be available to you.
