The City of Mississauga reviewed the Private and Public Tree Protection By-laws to ensure that they reflect current best practices.

Council approved the updated Public Protection Tree By-law and Private Tree Protection By-law and they took effect on April 1, 2022. These changes ensure that the City’s tree by-laws meet current urban forestry standards and help protect Mississauga’s tree canopy.

Public Tree Protection By-law updates

  • Clearer definition of what is a “City tree” and “shared tree” – both fall under the Public Tree By-law
  • You require a permit to injure a tree located on public property
  • You’re not allowed to store materials, equipment or anything that would affect the health of a tree’s roots
  • You’ll need approval to work within the tree protection zone and any grade (ground) changes are not allowed
  • Liquid, gaseous or solid substances are not allowed to be in contact with the tree’s root system
  • You’re not allowed to remove any woody debris, like branches, that have fallen or been cut down by the City in a natural area
  • You’re not allowed to plant trees on public land – a tree planted on public land falls under the Public Tree By-law

Private Tree Protection By-law updates

  • You need a permit to injure, destroy or remove any individual tree 15 cm (6 inches) in diameter or greater. A tree that size is typically a well-established, semi-mature tree that contributes to the overall health of an urban forest
  • We may refuse a permit based on the health of the tree
  • Trees located in interior courtyards are no longer exempt from the tree removal permit process
  • If you have a tree removal permit, you’ll need to notify the City when you begin planting replacement trees. Replacement trees ensure the recovery of removed trees that are healthy based on their size
  • A tree replacement is required for every 15 cm (6 inches) of diameter of the tree removed. For example, if you remove a tree with a diameter of 45 cm (18 inches), three replacement trees are required
  • Replacement trees, no matter the size, cannot be injured or removed without a permit

The City also amended the User Fees and Charges By-law to include the new permit fees for tree removal: $304 for one tree removal permit and $109.86 for each additional tree removal permit.”


So, that’s it. You cannot remove trees anywhere on your own property if the diameter of the trunk is 6 inches (15 cm) or more without permission. Otherwise, you face fines, including the replacement of the tree which can be costly.
