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.
