Hydro Ottawa offers many different options to allow you to make simple, on-time payments. Choose the method that’s most convenient for you. Once you’ve selected an option, please ensure you allow sufficient time for the payment to reach us by the due date. This time varies according to your payment option.

Automated Payment

Sign up for one of our automated payment plans and say goodbye to cheques and postage costs. It’s automatic, so you can be sure your payment will be made on time every month. Your bill will detail your account charges as well as the date of withdrawal from your bank account. There are two plans to choose from:

Pre-Authorized Payment

Once you have enrolled in our Pre-Authorized Payment Plan (PAP), the amount due will be automatically deducted from your bank account on the due date each month.

Equal Monthly Payment Plan

Our Equal Monthly Payment Plan (EMPP) allows you to spread your annual electricity costs evenly through the year for easier budgeting and a more predictable monthly bill. With EMPP, you pay the same amount every month. Learn more.

To enrol in one of our automated payment plans, select one of the options below. Your account must be up-to-date prior to registration.

Credit Card

It’s easy and convenient. At least five days before your bill is due, use your credit card to pay online or by telephone. Be sure to have your account number and credit card in hand. MasterCard is the only accepted credit card.

As of March 31, 2014, Hydro Ottawa is no longer permitted to accept Visa credit cards as a method of payment. Paymentus, our third party credit card payment processing service, has implemented this change due to a notification by VISA Canada that charging a fee to the purchaser for each payment processed is no longer permitted under the Visa International Operating Regulations.

While convenient, it is important to note that credit card payments are subject to a $5.95 fee for every $275 charged, not including the fee. Multiple transactions are permitted. This fee covers the handling and processing charges. The service fee is collected by Paymentus. Hydro Ottawa does not receive any portion of the fee.


If you are mailing a cheque or money order, please be sure to:

  • Send your payment at least five days before the due date;
  • Write your 20-digit account number on the front of your cheque or money order;
  • Include the remittance stub (the bottom portion of your bill below the dotted line); and
  • Place a stamp on the self-addressed envelope that was included with your bill. If using your own envelope, address it to:

Hydro Ottawa
PO Box 4483
Toronto, Ontario
M5W 5Z1

Note: Do not send cash by mail.


Bring the remittance stub (the bottom portion of your bill below the dotted line) to your bank or an automatic bank machine to make a payment on your account. You can also set up online payments to Hydro Ottawa. Choose your financial institution below.

Western Union

You can send bill payments to Hydro Ottawa by using Western Union’s Bill Payment Service. Western Union payments are considered ‘secured’ payments.

You’ll need Hydro Ottawa’s Code City, Code Province and your Hydro Ottawa account number in order to process your bill payment. The Code City for Hydro Ottawa is “OHEC Ontario” and the Code Province is “ON.” You’ll receive a Money Transfer Control Number (MTCN) on your receipt as confirmation that the payment was sent to Hydro Ottawa. Once your payment is made and your MTCN confirmed, Hydro Ottawa will receive automatic confirmation of your payment.
