Newmarket’s urban canopy is made up of both public and private trees and is a valuable infrastructure asset. The replacement value of Newmarket’s trees exceeds $350,000,000.​ The 2016 Urban Forestry Study showed that these trees help to:

  • Avoid more than 200,000 cubic metres of water runoff each year, a service valued at nearly $500,000. 
  • Reduce erosion, improve air quality, and increase property values. 
  • Reduce residential energy costs by more than $3,000,000 per year.
