When the Municipal Property Assessment Corporation, (an Ontario Crown corporation reporting to the Minister of Finance) released its report on the effect of wind turbines on property assessments (again, we caution readers that this is assessment, not appraisal), Wind Concerns Ontario released a statement to the effect that the report had a number of deficiencies, or  at least unusual parameters to the study, and that it was a “self-serving exercise.”
You may review our statement again here.
What we didn’t say was that there were aspects of the report that were unprofessional.
Just as the report on health effects by Colby et al in 2010 bizarrely claimed that not only was there no evidence of health problems from turbine noise there was so little evidence that no further research was warranted, the MPAC study spent considerable time trying to lay waste to the work done by Ontario real estate appraiser Ben Lansink. Mr Lansink, an AACI (accredited appraiser Canadian Institute), has appeared before numerous tribunals and in court as an expert witness on “injurious affection”; he studied several areas of Ontario where wind power projects operate, and documented the effect on property value.
Reviewers Michael McCann and Wayne Gulden have now done formal critiques of the MPAC study, and while criticizing its methodology and results,  also claim that the action of an Ontario Crown corporation to discredit a professional real estate appraiser were uncalled for.

The interesting thing is that the chief appraiser at MPAC is himself an AACI, i.e., not just an assessor, so there is a case to be made about the work done under his supervision, with regard to a fellow member of the Appraisal Institute of Canada. They have rules about such things. Those interested should contact the Institute’s Professional Practice section.
