Wind turbines near or on properties
For the 2012 and 2016 Assessment Updates, we surveyed the assessed values of properties within five kilometres of industrial wind turbines (IWTs) to determine if the properties had been fairly and accurately valued.
Impact of wind turbines on residential assessed property values
We conducted studies for the 2012 and 2016 assessments to compare the sales of Ontario properties located within five kilometres of industrial wind turbines (IWTs) with sales of properties located more than five kilometres away. Independent, third-party reviewers supported our conclusion that the assessments of properties near turbines were fair and accurate.
Our studies undergo rigorous independent third-party peer reviews before we publish them. The 2016 and 2012 reviews were conducted by Robert J. Gloudemans and include appendices describing the study parameters and documenting the analyses.
