Low Income Seniors Utility Rebate
Low-income seniors may now qualify for additional financial assistance through the new Seniors Utility Rebate.
If you qualify for the current Seniors Property Tax Rebate you will automatically qualify for the water related rebate, provided the property has an active metered water account. If you’re already receiving the tax rebate, no action is required to start receiving the utility rebate. The utility rebate will appear as a $175 credit on the June 2025 property tax bill.
If you are not receiving the Seniors Property Tax Rebate (65+) and want to to learn more visit the City's Tax Assistance Programs.
The Water, Wastewater and Stormwater program is self-sustaining. Revenue comes from billing residents for water use.
You are charged for water use based on your water meter reading. You receive a bill for your water use from Hamilton Utilities Billing (HUB). If you have questions regarding your water bill or payment options, contact Hamilton Utilities Billing, call 905-546-8630 or email [email protected].

What water rates pay for
Delivery of safe, reliable drinking water to citizens and businesses of Hamilton. Hamilton’s water comes from Lake Ontario and our water treatment and distribution systems make it ready for you to drink straight from the tap.
Collection and treatment of wastewater and stormwater. Collecting and treating rain water, storm run-off and sanitary waste from domestic, commercial, and industrial activity is key to preventing source water pollution and protecting public health.
Operating, maintaining, replacing and rehabilitating aging water, wastewater and stormwater sewer systems including:
Water meter installation, reading and maintenance. In addition to measuring consumption allowing us to charge fairly based on volumetric use, metering provides an incentive for water conservation and preservation of this invaluable, life-sustaining resource.
Capital infrastructure investments to improve water and wastewater processes ensuring fiscal and environmental sustainability. The current replacement value of our water, wastewater and stormwater infrastructure is $10 billion.
New Provincial Legislation that is reducing revenue from development charges and costs from other regulatory changes.
Reducing costs
In an effort to reduce costs the City of Hamilton has:

Water Rates
Stormwater Funding
The City will implement a stormwater fee starting in 2027. This fee will be a more fair and equitable way for property owners to pay for stormwater services in Hamilton than the current approach.
How do we compare to other municipalities?
Hamilton’s water, wastewater and stormwater rates are among the lowest in Ontario. Hamilton has the third lowest water costs in 2024 at $965 for 200 m3/year amongst the cities in our region as shown below:
Why are rates increasing?
The majority of the water rate increase is due to new provincial legislation that is reducing revenue from development charges and costs from other regulatory changes. The remainder of the water rate increase represents the increased costs of delivering water, wastewater and stormwater services. Water and wastewater budgets contain fixed costs that do not change in direct proportion to water consumption. The cost to distribute, collect and treat municipal water and wastewater throughout the City remains relatively constant, regardless of the volume consumed by all residents.
A portion of your bill is used for capital renewal and expansion of the City’s overall water/wastewater/stormwater infrastructure which has a replacement value of $14 billion. Aging City infrastructure becomes more costly to operate, maintain and replace with over 20% of the City’s water and sewer mains being more than 80 years old.
