Land OwnerCity of Toronto
Historically, Sun Valley was used as a landfill for many years until its closure in 1965. Beneath the ground, waste is compacted 20 to 25 meters deep throughout the site’s 8.4 hectares. After the landfill was closed, the area was covered over with topsoil and allowed to revert to a naturalized state.
Although the current early stages of Sun Valley’s naturalization resemble a meadow habitat, the ultimate goal is to restore parts of the area to a forest ecosystem. With the help of community volunteers, extensive plantings of native trees and shrubs will assist the natural regeneration of the site. Since 2004, approximately 5000 trees have been planted in Sun Valley. The re-vegetation of Sun Valley will connect it with the adjacent forest of Crothers Woods, which is designated as an Environmentally Significant Area.
