Property Tax by Province

Ontario legislation currently mandates a four-year assessment cycle.

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

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.

Mastering Ontario’s Complex Assessment and Tax Framework
Ontario’s property tax system is shaped by deferred reassessments, varying municipal practices, and opaque MPAC methodologies that leave many property owners without clear insight into valuation accuracy. Our Ontario property tax professionals provide the analytical depth and strategic guidance needed to navigate this landscape, minimize liability, and protect portfolio value.
Challenge Property Assessments with Expert-Led Appeals
Independent valuation analyses are conducted annually to benchmark your property’s fair and equitable assessment. When discrepancies with MPAC’s determinations are identified, we manage the entire appeal process, from building defensible valuation evidence and preparing all documentation to representing your interests in both formal and informal proceedings. Each step is designed to secure an accurate and defensible assessment.
Secure Provincial Credits
Ontario offers a range of provincial tax credits, rebates, and relief programs that can reduce overall tax exposure. Our specialists interpret eligibility criteria, documentation requirements, and application timing to ensure your business captures all available incentives and unlocks meaningful financial savings.
Gain Access to Critical Tax Data
Our proprietary technology consolidates Ontario’s fragmented assessment and taxation data into a unified, real-time platform. With advanced analytics and clear portfolio visibility, our experts develop informed, data-driven strategies that enhance decision-making, improve compliance, and strengthen long-term tax performance.
