Taxation and Finance Ontario 3 Minutes Read · published May 24, 2026 Flag of Ontario

Richmond Hill, Ontario property owners who disagree with their MPAC assessment can request a review and, if needed, appeal to the provincial tribunal that handles assessment disputes. This guide explains the roles of MPAC and the assessment tribunal, the steps to challenge an assessment, common outcomes, enforcement implications for municipal taxes, and where to find official forms and contacts.

Overview of the appeal process

Assessment challenges in Ontario start with the Municipal Property Assessment Corporation (MPAC). Many owners begin with a Request for Reconsideration (RFR) or contact MPAC for a review before pursuing a formal hearing with the provincial tribunal. If you progress to a hearing, the Assessment Review Board or its current tribunal body handles disputes and renders binding decisions. See MPAC and the tribunal for official steps and forms MPAC guidance[1] and Tribunals Ontario - assessment tribunal[2].

Penalties & Enforcement

Appealing an assessment changes the assessed value used to calculate municipal taxes, but filing an appeal does not automatically change tax billing or collection by the City of Richmond Hill. The city's tax collection and penalty rules remain in force while appeals proceed; for details on tax payment obligations and collection, consult the City of Richmond Hill tax pages Richmond Hill tax information[3].
