Property Assessment Information

Assessment Cycle Updates

On March 22, 2008 Bill 187, the Budget Measures and Interim Appropriation Act, 2007, introduced measures that transform Ontario's property tax assessment system by implementing a four-year assessment cycle with a four-year assessment phase-in. This means that re-assessments will only happen every four years (2008, 2012, 2016) and increases in assessment will be phased in equally over four years instead of being added to the roll in the year of re-assessment.The phase-in of assessments will apply to all property classes.To illustrate, the following table below shows the timing of the present valuation cycle and the timing of future reassessments with applicable valuation dates.

Reassessment Year Valuation Date for
Reassessment
Tax Years to which the
Valuation Date would Apply
Present Cycle
2006 January 1, 2005 2006, 2007, 2008
Four-Year Reassessment Cycle
2009 January 1, 2008 2009, 2010, 2011, 2012
2013 January 1, 2012 2013, 2014, 2015, 2016
2017 January 1, 2016 2017, 2018, 2019, 2020
2021 January 1, 2020 2021, 2022, 2023, 2024

The following provides an example of the phase-in of an assessment increase:

 Property Classification Residential
 Property value as of January 1, 2008 $220,000
 Property value as of January 1, 2005 $180,000
 Over 3 Years the property's value changed by  $ 40,000


Therefore, the "phase-in" of the assessment increase would be:

 2009 Tax Year  $190,000
 2010 Tax Year  $200,000
 2011 Tax Year  $210,000
 2012 Tax Year $220,000


The phase-in benefits property owners in that those with increases in assessment significantly above the average won't be faced with a corresponding significant increase in taxes in the year of re-assessment; the increase will be phased over four years.

Assessment Appeal Process

The government has established a two-stage appeal process with clearer filing deadlines and standardized information disclosure protocols. The two steps involve (1) filing a Request for Reconsideration (RfR) and (2) appealing to the ARB.

Beginning in 2009, filing a RfR is the mandatory first step for properties in the residential, farm and managed forest property classes. Filing a RfR is not a mandatory first step for all other property classes (for example, business classes). For 2009 and subsequent years a RfR is a pre-condition for appealing properties in residential, farm and managed forest property classes.

The deadline for filing a RfR for 2009 and subsequent years is:

  • Regular Assessment Notices - March 31 of taxation year
  • Supplementary/Omitted Notices - within 90 days of Notice mailing

If a property owner is not satisfied with the results of the RfR they may appeal to the Assessment Review Board. ARB Appeal deadlines for 2009 are:

  • Regular Assessment Notices - 90 days after the mailing of the results of the RfR or March 31 of the tax year for property owners in business classes who do not file an RfR
  • Supplementary/Omitted Notices - 90 days after Notice mailing where RfR is not a pre-condition of appeal
