Who sets the rate

Two bodies set St Marys's rate: St Marys council and the Province of Ontario, for schools. St Marys has no county above it, so there is no county or region portion: its own rate of 1.31% already pays for services that a county would run elsewhere. That is also why comparing St Marys's municipal rate directly against a township's understates what the township actually pays.

Total residential rate, with the tax on a $500,000 home underneath.

Each part of the rate, year by year

Over the same years the residential assessment base moved from $731M to $797M, and the residential levy collected went from $10M to $12M. A rate rising while the base also grows means the budget grew faster than property values; a rate falling while the base grows usually means the opposite. Assessment is the figure on the MPAC notice, still based on 2016 values province-wide.

Why are St Marys property taxes so high?

They are not, measured against the rest of the province. St Marys's total rate of 1.46% sits close to the Ontario middle of 1.40%: higher than 58% of 414 municipalities. A bill can still feel high when the assessment is high, because the rate is only half of the calculation.

Home values

Homes here are assessed at $229,167 per household, 25% more than the middle ($183,474). Higher values let it raise the same money per household at a lower rate.

Ontario has no official cost-of-living index for single towns. Statistics Canada’s consumer price index covers only Toronto, Ottawa and Thunder Bay here, and it measures change over time, not the gap between places. These are the costs published for each municipality: what renters paid and owners estimated in the 2021 Census, not today’s asking rents or sale prices.
