Cornwall's 2026 residential mill rate is 7.5000 mills, plus an education levy of 2.5000 mills. On the local median assessed home value of $347,050, that combination works out to roughly $2,603 per year before other municipal charges.

The commercial mill rate in Cornwall is 10.5000 mills, higher than the residential rate. Municipal mill rates set the tax charged per $1,000 of assessed property value and typically change annually with council budgets and reassessments.

How to read this

One mill equals $1 of tax per $1,000 of assessed value. Rates are compiled from provincial open schedules and municipal tax bylaws, then normalized to mills where the source allows. Assessment systems differ (BC Assessment, Ontario MPAC phase-in, Alberta market value, Nova Scotia capped assessment), so cross-province rate rankings are not dollar rankings until bases align.

Start with the residential mill rate and the sample bill on a median assessed home, then ask whether education or regional levies sit on top. Municipal rate is the piece council sets; your notice may show a higher total. Compare cities on a similar assessed value, and keep class in mind (residential vs commercial or multi-residential).

Use the calculator for a rough personal estimate, then confirm the current tax bylaw and your assessment notice before budgeting or a purchase decision. Method detail: methodology.
