Assessed value is the MPAC value on your assessment notice, not market value. Ontario has kept assessments at January 1, 2016 values since 2017, so a home bought recently is usually assessed well below its purchase price. Estimates exclude local improvement charges, business improvement area levies and any rebates.

About these numbers

What is an effective tax rate?
Total property taxes billed to a class divided by that class's taxable assessment. It is the average rate actually paid, so it can differ slightly from the rate printed in the municipal by-law when a municipality applies different rates to subclasses, phase-ins or special area levies.
Why is my bill different?
Your bill depends on your own assessed value, any special area charges, capping or phase-in adjustments and local improvement charges. Use the rate here to compare municipalities, and your assessment notice to estimate your own bill.
Where does the data come from?
Every Ontario municipality files an audited Financial Information Return with the Ministry of Municipal Affairs and Housing. These pages use Schedule 26A, "Taxation and Payments-in-Lieu Summary", for 2016 through 2024. Cornwall's latest return was updated 2026-09-29. See the methodology.
