Important Notice to Municipal Water Customers in the cities of Guelph, Hamilton, Markham & Vaughan

Alectra Utilities is the current billing service provider on behalf of the cities of Guelph, Hamilton, Markham, and Vaughan for water and wastewater charges. Starting in spring 2026 for Hamilton, and summer 2026 for Guelph, your water and wastewater charges will be billed directly to you by your local municipality and will no longer appear on the electricity bill you receive from Alectra Utilities.

More information will be provided in 2025/2026, until then, no action is needed. You will continue to receive a combined electricity and water bill from Alectra Utilities until this transition occurs.

Alectra Utilities is working with each of the cities to ensure a smooth transition. More information will be provided to customers as we transfer water billing services back to your local municipality.

Hamilton Water Billing – Spring 2026

Starting in spring 2026, the City of Hamilton is transitioning water, wastewater and stormwater billing from Alectra Utilities, enabling the Hamilton Utilities Billing (HUB) team to manage water meter reading, billing and customer service. Until the transition occurs, water-related billing and payments will remain the same.

Alectra Utilities will continue to provide electricity customer care and billing services for Hamilton. There is no change to your electricity service. After the water billing transition to HUB in spring 2026, your electricity bills will no longer include water and wastewater charges.

Pre-authorized Payments

Customers currently enrolled in pre-authorized payments with Alectra will need to re-enrol with Hamilton Utilities Billing before the transition in April 2026. If you would like to continue this convenient bill payment method, please re-enrol before March 20, 2026, to allow sufficient processing time.

Existing pre-authorized payment arrangements with Alectra will not transfer automatically. To support a smooth transition, all affected residents have been mailed step-by-step instructions outlining how to transfer their pre-authorized payment to Hamilton Utilities Billing ahead of the transition, along with a prepaid, addressed envelope for convenience.

For more information on how to re-enrol for HUB pre-authorized payments, please visit: Hamilton.ca/HUB

We’re committed to keeping you informed about these important changes. As we get closer to the transition in spring 2026, we will provide more details about how these changes will affect you.
