How we assess commercial properties

  • Depending on the characteristics of the property and the current use, we may use any one of three approaches to value the property. 
  • We use the cost approach to value most commercial properties. 
  • However, in the GTA where there are an abundance of sales, we use the direct comparison approach to establish current value assessments. Learn more about our approaches to value.
  • Occasionally, we may use the income approach to calculate the value of a commercial property.
