Property Value Assessment
What it means to you

In the spring of 2016, residents received their updated property assessment notices from the Municipal Property Assessment Corporation (MPAC) based on a January 1, 2016 valuation date.

How Municipal Tax is Cal​​cul​ated

Municipal tax i​s calculated by multiplying your property's current year phased-in assessment by the City's tax rate as approved by City Council​This means that any increase in tax you may see is not always due to the City raising the tax rate. An increase in tax may also be based on a change in your assessed property value as well as the assessed value of everyone else's property in the municipality.

An increase in assessed value does not necessarily result in an increase in property taxes. Your asse​​ssed value is used to determine your share of the total taxes, so if the increase in your assessed value is the same as the average assessment increase for the City of Barrie, you would not experience an assessment-related increase in taxes. If, however, your assessed value increase is higher than the average, you may experience an assessment-related increase.

MPAC's Phase-in Program​​

This 2016 assessment is the third reassessment since 2005 however, in order to smooth out housing market changes, the increase in assessment values will be phased in over a four-year period, from 2017 to 2020. Below is an example of how the phase-in program works.

Valuation DateJan 1/12Jan 1/16Jan 1/16Jan 1/16Jan 1/16

Assessed Value for Tax Purposes$218,000$224,000$230,000$236,000$242,000
Phase in amount calculation = (242,000 – 218,000) / 4 = 6,000.

Frequently Asked Questions
Prepared by MPAC​

Who is MPAC?

MPAC is a non-share capital, not-for-profit corporation responsible for providing Ontario property owners, tenants, municipalities, and government and business stakeholders with consistent and accurate property assessments in accordance with the Assessment Act and related regulations.

Why does MPAC assess my property?

Each municipality across Ontario uses MPAC’s current value assessment and classification of your property to set municipal tax rates and collect property taxes.

How has MPAC assessed my property?

Based on January 1, 2016 data, MPAC analyzed property sales in your community and also considered other features impacting market value such as location, lot dimensions, living area, age of the property, renovations or additions, and quality of construction. The next province-wide assessment will take place in 2020.

How will my property assessment affect my taxes?

An increase in assessed value of your property does not necessarily mean an increase in your property taxes. Only if your property value has surpassed the average percentage change of residential properties in your municipal/local taxing authority (as indicated on your notice) will you possibly pay an increase. In addition, to ease tax-payers, property value increases from 2016 will be phased in gradually over the following four years.  Conversely, any property value decrease will be applied immediately.

How can I tell if the assessment is accurate?

You can determine accuracy in three ways: First, ask yourself whether you could have sold your property on January 1, 2016 for the assessed value on your notice; Second, check your property details included on the notice and online at AboutMyProperty™ at, as well as that of up to 24 comparable properties of your choice and six selected by MPAC, free of charge; Third, check the December/January selling prices of houses in your neighborhood.

What can I do if my assessed value is incorrect?

If you disagree with MPAC's assessment or classification of the subject property, you can file a Request for Reconsideration (RfR) and MPAC will review your assessment, free of charge.   The deadline to File and RfR is included on each property owner's Notice.

Starting in 2016 (for the 2017 property tax year) You can request MPAC review your assessment within 120 days from the Issue Date of your Property Assessment Notice to file a free RfR, to ensure you receive a fair and consistent review of property assessment.  the issue date and property owner's unique RfR deadline has been included on every Property Assessment Notice.

There are two ways to file an RfR:

  • At  Property owners are able to attach documents, pictures and reports to accompany their RfR, as well as check the status of their request.  Property owners may also mail or fax their form to MPAC.   Forms are found at
  • Write a letter to request an RfR.  The letter should include the 19-digit Roll Number found on the Property Assessment Notice, the owner's full name, address and phone number, and the reasons why their assessment is incorrect, including any information obtained to support your request.
Where can I get more information?
