Property Tax by Province

01

Ontario legislation currently mandates a four-year assessment cycle.

02

Province-wide reassessments have been deferred since 2020. As a result, property taxes in 2026 will continue to be based on assessed values that reflect 2016 assessment data.

03

The Municipal Property Assessment Corporation (MPAC) determines assessed values using a mass appraisal system informed by the direct comparison, income, and cost approaches, depending on property type.

Our Ontario property tax professionals provide the analytical depth and strategic guidance needed to navigate this landscape, minimize liability, and protect portfolio value.
