Landowners should have dead trees professionally removed from their property as soon as possible to prevent damages to property or -injuries from falling branches.

The Private Tree Protection By-law (0254-2012) ensures the provision, protection and enhancement Mississauga’s existing tree cover while respecting a landowner’s right to make changes to the landscape of their property in an environmentally responsible manner.

If you would like to remove trees from your private property, you must ensure you comply with the Private Tree Protection By-law.

When do Landowners Need a Permit to Remove Trees?


  • Three or more trees 15 cm (six inches) or more in diameter per calendar year.
  • Three or more dead, dying or hazardous trees over 15 cm (six inches) in diameter per calendar year



  • All trees 14 cm (5.5 inches) or less in diameter.

For residents with dead or dying Ash trees on their property, a Certified Arborist can sign off on the application form to confirm that the trees are dead or dying due to Emerald Ash Borer (EAB).

If a tree is dead, dying or hazardous, the permit fee is waived and no replacement trees are required. However, landowners are encouraged to plant new species of trees to help restore and maintain our urban forest.
