Assessment Review Board (ARB) – Toronto, ON

Assessment Review Board (ARB) – Toronto

The Assessment Review Board (ARB) is an independent adjudicative tribunal established under the authority of the Province of Ontario to hear appeals regarding property assessment and classification. Operating under the umbrella of Tribunals Ontario, the ARB plays a critical role in the municipal taxation system by ensuring that property assessments, which form the basis for calculating property taxes, are fair, accurate, and consistent. The board’s Toronto office, located at 15 Grosvenor Street, serves as the administrative center for processing appeals from across the province, although the impact of its decisions is felt locally by homeowners and businesses. The ARB operates under the Assessment Act and has the authority to change the Current Value Assessment (CVA) and the tax classification of a property, but it does not directly set property tax rates, which is a function of municipal councils.

Mandate and Scope of Authority

The primary function of the ARB is to resolve disputes between property owners and the Municipal Property Assessment Corporation (MPAC). MPAC is responsible for assessing all properties in Ontario, and when an owner disagrees with that assessment, the ARB is the final arbiter of fact. The board handles a wide variety of cases, ranging from single-family residential homes to large, complex industrial and commercial complexes. Key areas of adjudication include:

• Assessment Appeals: Determining if the assessed value of a property reflects its true market value as of the legislated valuation date.
• Classification Appeals: Deciding if a property has been placed in the correct tax class (e.g., residential, commercial, industrial, farm, or managed forest), which significantly impacts the tax rate applied.
• Tax Exemptions: Hearing disputes regarding whether a property qualifies for exemption from taxation, such as those owned by charitable or religious organizations.
• Sickness and Poverty Applications: In specific circumstances, the board may hear appeals related to tax relief applications made to municipalities.

The Appeal Process and Requirements

The process for bringing a matter before the ARB is structured and governed by strict deadlines. For residential, farm, and managed forest properties, a property owner must first file a Request for Reconsideration (RfR) with MPAC before they can appeal to the ARB. This step is mandatory and allows MPAC to review the data without formal litigation. If the owner is not satisfied with the RfR outcome, they may then file an appeal with the ARB. For commercial and industrial properties, owners can appeal directly to the ARB without the RfR step. Appeals must be filed by March 31st of the tax year in question. The board utilizes a ‘Schedule of Events’ to manage cases, setting firm dates for the exchange of documents, evidence, and statements of issues. This ensures that all parties-the property owner, MPAC, and the municipality-are prepared and that cases move efficiently toward resolution.

Mediation and Hearings

The ARB places a strong emphasis on dispute resolution prior to a full hearing. Many cases are resolved through mediation or settlement conferences, where a board member facilitates a discussion between the parties to reach a mutually instantaneous agreement. If a settlement cannot be reached, the matter proceeds to a hearing. Hearings may be conducted in writing, by teleconference, by video conference, or in rare cases, in person. The board member acts as the decision-maker, hearing sworn testimony, reviewing expert appraisal reports, and applying the law to determine the correct assessment. The burden of proof typically lies with MPAC to demonstrate that their assessment is correct, but the appellant must also provide cogent evidence to support a different value. Decisions made by the ARB are binding, though they can be appealed to the Divisional Court on points of law.

Practical Information for Appellants

Accessing the services of the ARB requires payment of filing fees, which vary depending on the property type. Fee waivers are available for individuals who meet financial eligibility criteria. It is important for appellants to understand that the ARB is a separate entity from the municipality that sends the tax bill. Winning an assessment appeal may result in a retroactive adjustment to taxes owed, which the municipality will process after the ARB issues its decision. The office at 15 Grosvenor Street is part of a government complex with high security; visitors must have valid identification and an appointment. The board provides services in both English and French, respecting Ontario’s bilingual status.
