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. St Catharines's latest return was updated 2026-03-25. See the methodology.
