Private Tree Protection By-law

The City of Mississauga is establishing a sustainable tree canopy through the implementation of new guidelines for tree removal on private property. The Private Tree Protection By-law (0254-2012) will protect and enhance 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.

Whether you are a homeowner, a business owner or a developer wishing to remove trees from private property, you must comply with the Private Tree Protection By-lawPDF Document.


A certified arborist can sign off on the application form to confirm that the Ash trees are dead or dying due to Emerald Ash Borer. This will help to streamline the application approval process for Ash trees.

As with any dead or dying tree there will be no fee required.
