Tax Department Relocation

Effective July 13, 2026, the Tax Department has relocated to the main floor of the Cornwall Civic Complex (100 Water St. East).

In-person tax and water bill payments are no longer accepted at City Hall. Please visit our new office at the Civic Complex for all in-person services. Free parking is available on-site.

The secure drop box outside City Hall remains available, and online or pre-authorized banking methods remain unchanged. Please contact (613) 930-2787 ext. 2317 or send us an email at billing@cornwall.ca for more information.

Important Notice: Unsolicited Water Testing Offers

Jan 20, 2026
The City of Cornwall is warning residents about unsolicited packages being left at homes, asking homeowners to provide water samples for “free water quality analysis.”
These offers are not affiliated with the City and are often linked to high-pressure sales tactics promoting costly and unnecessary in-home water treatment systems.
Your drinking water is safe. Cornwall’s water supply is rigorously tested and monitored to meet all provincial safety and quality standards.

Verified test results are published each year in our Annual Drinking Water Quality Report → https://loom.ly/Jv4DSC0

If you have questions or concerns about your water:
