Stormwater Fee Estimator Tool Launches

The City of Hamilton is making important strides toward protecting our waterways, preventing local flooding, and preparing for future environmental challenges. Beginning April 2026, a new stormwater fee will be introduced to ensure that maintaining our stormwater infrastructure is done in a fair, sustainable, and financially responsible way.

Currently, funding for stormwater management in Hamilton comes from wastewater fees based on drinking water usage — a system that doesn’t fully reflect the real impact properties have on runoff and infrastructure wear. The new system will shift to a load-based model, meaning the fee you pay will be based on the runoff your property generates.

Residential properties like single-family homes, duplexes, townhomes, and small multiplexes will see a simple fixed rate, while non-residential and larger multi-residential properties will pay based on the amount of hard surfaces they have, such as driveways and rooftops. This approach aimed to ensure that everyone contributes fairly to the upkeep of our shared infrastructure.

Standing Up for Rural Fairness

From the beginning, Councillor Mark Tadeson strongly advocated for the exclusion of rural farms and properties not connected to the built system from the new stormwater tax, recognizing the unique realities of rural living and the benefit of these high-greenspace properties to water management. Although Council ultimately did not support this exemption, Mark remains committed to fighting for fair and equitable treatment of rural property owners. He will continue to push for solutions that respect the rural character of Ward 11 and ensure that all residents are treated fairly.

Incentive Programs and Tools

To support residents and businesses before the new fee begins, the City has launched several important initiatives:

✅ Stormwater Incentive Program

Homeowners can access the Rain Ready Rebate through Green Venture for installing rain barrels, permeable driveways, and other runoff-reducing features.Farms, parks, and other non-residential properties may automatically qualify for a Green Space Credit.Large properties and commercial owners can apply for additional credits, including up to 50% off for installing stormwater-reducing features, or up to 90% off if stormwater is safely discharged directly into Lake Ontario.

✅ Fee Estimator Tool

Why This Matters for Ward 11

Councillor Mark Tadeson is committed advocating for rural and suburban areas like Ward 11, fighting that they be represented fairly in city initiatives. While rural areas may have fewer hard surfaces, roadways and driveways - the argument is that they still contribute runoff, and responsible stormwater management benefits all property owners by reducing erosion, preserving farmland, and protecting our cherished natural landscapes.

Mark continues to advocate for clear communication, support for residents, and minimal disruption as these changes are implemented. These programs are designed to reward proactive environmental stewardship, build resilience against climate change, and keep our communities strong for generations to come.
