Join the One Million Trees program as we celebrate our 10-year anniversary and help enhance Mississauga’s open spaces and forested areas for future generations to enjoy.

Whether you participate in a City tree planting event or plant on your private property, each tree counts. Add your tree to our tally and have it count towards the City’s goal of planting one million trees.

Why plant trees

There are 2.1 million trees in Mississauga which improve the environment, health and quality of life for all. Trees provide many benefits by helping:

  • Improve air quality and clean air
  • Reduce smog and the effects of pollution
  • Create shade
  • Provide habitat for birds and other wildlife
  • Decrease energy demand for cooling in summer (by shading buildings) and heat in winter (through windbreaks)
  • Prevent flooding and reduce peak stormwater run-off volumes
  • Increase property values and aesthetics that strengthen communities
  • Encourage healthy living and mental well-being
