Confirmed residential mill rates for the 10 Ontario municipalities we track, how the province's assessment and tax-class system works, key dates, and how each city compares.
MPAC assesses every Ontario property using the RTC/RTQ class-code system. Values are still based on the 2016 base year, and your bill combines a municipal rate with a provincial education rate.
Confirmed residential mill rates, lowest to highest. The percentage is the rate as a share of assessed value. Linked cities have a full breakdown, 10-year trend, and a forward projection.

Rates with a year badge are confirmed for that year; others reflect the most recent confirmed bylaw, updated as municipalities finalize new rates. The average is taken across the 10 Ontario municipalities we currently track and will broaden as more are added. Always verify with the municipality before making financial decisions.
Assessment and payment timing is set locally, but the Ontario cycle generally follows this pattern.
| When | What happens |
|---|---|
| Jan 1, 2016 | Valuation date in effect — 2026 taxes still use fully phased-in January 1, 2016 values. No new province-wide update has been scheduled. |
| When changed | Assessment notice issued — MPAC mails a notice only when your property changes (sale, addition, use change). Otherwise the 2016 value carries forward. |
| March 31 | Request for Reconsideration — RfR deadline for the tax year (March 31, 2026 for 2026), or the date on your notice. Business owners may appeal directly to the ARB. |
| Apr to Jun | Council confirms tax rates — Municipalities set the year's tax rates. We update as each is confirmed. |
| Varies | Property tax instalments due — Interim and final bills with due dates set by your municipality, often in several instalments. |
