Property Tax & Assessment Appeal Appraisals
Independent Property Valuations for MPAC Assessment Reviews & Property Assessment Appeals
If you believe your property's assessed value does not accurately reflect its market value for the applicable valuation date, you may have options to challenge the assessment.
A professional real estate appraisal can provide independent market evidence to help property owners and their advisors better understand the value of the property and determine whether the assessed value is supportable.
Cade Appraisals Inc. provides independent property tax and assessment appeal appraisals for residential, commercial, industrial, multi-residential, rural, agricultural and other real estate.
Our role is to provide an objective and well-supported opinion of property value. We do not determine your property taxes or guarantee the outcome of an assessment review or appeal.
Understanding Property Assessment in Ontario
In Ontario, property assessments are administered by the Municipal Property Assessment Corporation, commonly known as MPAC.
Property assessment and property taxes are related, but they are not the same thing.
The assessed value is the value assigned to the property for taxation purposes. Municipalities then use property assessments together with applicable tax rates to calculate property taxes.
If you believe the assessed value or classification of your property is incorrect, Ontario provides processes through which the assessment can be reviewed or appealed.
What Is a Property Assessment Appeal Appraisal?
A property assessment appeal appraisal is an independent professional valuation prepared to provide market evidence regarding the value of a property for assessment-related purposes.
The appraisal examines the property itself together with relevant market information applicable to the required valuation date.
Depending on the assignment, the appraiser may consider:
Property location
Lot size and characteristics
Building size
Age and condition
Quality of construction
Renovations and improvements
Property use
Zoning
Income-producing characteristics
Comparable property sales
Market conditions
Other characteristics affecting value
The objective is to develop an independent opinion of value supported by relevant market evidence.
What If I Disagree With My MPAC Assessment?
If you disagree with your property's assessed value or classification, you may be able to file a Request for Reconsideration, commonly called an RfR.
MPAC describes the RfR as an opportunity to have the assessment reviewed in detail. There is no fee to file an RfR. Supporting information can be submitted as part of the review, including photographs, sales information and reports.
This is where an independent appraisal may be valuable.
Rather than simply stating that you believe the assessment is too high or too low, an appraisal provides professional valuation analysis supported by property and market evidence.
What Is a Request for Reconsideration?
A Request for Reconsideration asks MPAC to review a property's assessment.
Property owners may file an RfR if they believe their assessed value or property classification is incorrect or if information about the property needs to be corrected.
For properties classified as residential, farm or managed forest, an RfR generally must be completed before the owner can appeal the assessment to Ontario's Assessment Review Board.
Deadlines are important. MPAC advises property owners to refer to their Property Assessment Notice for the applicable RfR deadline.
What Is the Assessment Review Board?
The Assessment Review Board, commonly called the ARB, is an independent Ontario tribunal that hears property assessment appeals, including disputes concerning assessed value and property classification.
If a property owner remains dissatisfied after the applicable MPAC reconsideration process, an appeal may be available through the ARB.
The exact procedure depends on the property classification and circumstances, so property owners should confirm current requirements directly with MPAC and the Assessment Review Board before proceeding.
How Can an Appraisal Help With a Property Assessment Dispute?
A successful valuation argument should be based on market evidence rather than simply comparing tax bills with neighbours.
A professional appraisal can provide an independent analysis of the property and relevant market data for the appropriate effective date.
Depending on the circumstances, an appraisal may help identify:
Differences between the subject property and comparable properties
Physical characteristics affecting value
Location influences
Condition issues
Functional limitations
Land characteristics
Relevant comparable sales
Market conditions applicable to the valuation date
Other property-specific factors affecting market value
The appraisal provides valuation evidence. MPAC or the Assessment Review Board ultimately determines the outcome of the assessment matter.
What If MPAC Has Incorrect Information About My Property?
Sometimes the issue may involve the property information itself rather than simply a disagreement about value.
For example, MPAC specifically identifies incorrect building size or land area as examples of property information an owner may seek to correct through a Request for Reconsideration.
Other property characteristics may also be relevant depending on the situation.
When completing an appraisal, the appraiser independently researches and observes property characteristics relevant to the valuation assignment.
Differences between available records and the actual property should be investigated rather than automatically assumed to be correct.
Comparable Sales Matter
One of the most important components of many property valuation assignments is the analysis of comparable sales.
However, simply finding a nearby property that sold for less does not necessarily prove that an assessment is incorrect.
Properties can differ significantly in:
Location
Lot size
Building size
Age
Condition
Quality
Renovations
Basement finish
Garage facilities
Outbuildings
Views
Waterfront characteristics
Property use
Zoning
Other features
The appraiser analyzes these differences to determine which sales provide meaningful evidence regarding the value of the subject property.
The Valuation Date Matters
This is particularly important for property assessment work.
The question is not necessarily:
“What is my property worth today?”
The relevant question may instead be:
“What was my property worth as of the valuation date applicable to the assessment?”
Ontario's Assessment Review Board explains that property assessments are based on
current value as of a specific date.
For 2026, MPAC's current forms state that assessments continue to reflect the legislated valuation date of January 1, 2016, unless changes to the property apply.
Because assessment cycles and valuation dates can change, the correct effective date should always be confirmed for the particular tax year and assessment being challenged.
Property Assessment vs. Current Market Value
A homeowner may look at their assessment and compare it with what homes are selling for today.
That comparison can be misleading if the assessment relates to a different valuation date.
Real estate markets change.
Prices can increase or decrease because of supply and demand, financing conditions, buyer behaviour and broader economic conditions.
For an assessment-related appraisal, the appraiser must analyze the property within the appropriate valuation framework and effective date rather than simply applying today's market value.
Residential Property Assessment Appraisals
Residential assessment disputes may involve:
Detached homes
Semi-detached homes
Townhouses
Condominiums
Luxury homes
Waterfront properties
Cottages
Rural residences
Large residential properties
Unique homes
Properties with significant condition issues
The appraisal considers the characteristics of the property and relevant market evidence for
the assignment.
Commercial & Investment Property Assessment Appraisals
Assessment disputes are not limited to homeowners.
Commercial, industrial, multi-residential and other income-producing properties can involve more complex valuation considerations.
Depending on the property, analysis may include:
Comparable sales
Rental income
Operating expenses
Market rents
Vacancy
Capitalization rates
Property use
Zoning
Land characteristics
Other market evidence
The appropriate valuation methodology depends on the property and the appraisal assignment.
Rural, Agricultural & Unique Properties
Some properties are particularly difficult to compare using standardized assessment information alone.
Rural and agricultural properties may contain a combination of land, residences, barns, workshops, outbuildings and other improvements.
Waterfront properties may differ in frontage, shoreline, access, views and lot utility.
Large or unusual properties may have very few directly comparable transactions.
In these situations, professional appraisal analysis can help identify and evaluate the characteristics that market participants recognize when determining value.
Will an Appraisal Automatically Lower My Property Assessment?
No.
Obtaining an appraisal does not guarantee that MPAC or the Assessment Review Board will change your assessment.
In fact, an independent appraisal may conclude that the assessed value is reasonable, lower than market value or higher than the appraiser's opinion of value.
An appraiser's responsibility is not to produce a predetermined number.
The purpose is to provide an independent and supportable opinion of value based on the available evidence.
That independence is particularly important when an appraisal may be relied upon in a dispute or appeal.
Frequently Asked Questions About Property Assessment Appeals
Can I challenge my MPAC property assessment?
Yes. MPAC provides a Request for Reconsideration process for owners who disagree with
their assessed value or classification. Depending on the property type and circumstances, an appeal to the Assessment Review Board may also be available.
Does it cost money to file a Request for Reconsideration?
MPAC states that filing a Request for Reconsideration is free.
Do homeowners have to file an RfR before appealing to the ARB?
For residential, farm and managed forest properties, MPAC states that owners must first file a Request for Reconsideration before becoming eligible to appeal to the Assessment Review Board. Different rules apply to some non-residential properties.
Can an appraisal guarantee my assessment will be reduced?
No. An appraisal provides independent valuation evidence. MPAC or the Assessment Review Board determines whether an assessment should be changed.
Can you appraise commercial property for an assessment appeal?
Yes. Depending on the assignment, appraisal services can be provided for residential, commercial, industrial, multi-residential, rural and other real estate.
What if my property's information is incorrect?
Incorrect property information may be relevant to an assessment review. MPAC specifically allows property owners to raise property-data concerns through its Request for Reconsideration process.
Should I get an appraisal before filing an appeal?
That depends on the property, value in dispute and stage of the process. Because there are filing deadlines and procedural requirements, it is a good idea to understand the applicable MPAC or ARB process before commissioning valuation work.
