Tree Bylaws in Mississauga

Mississauga updated its private tree protection rules significantly with By-law 0021-2022, which replaced the former By-law 0474-2005 in April 2022. The current bylaw protects all private trees with a diameter of 15 cm or more, which is a lower threshold than many neighbouring municipalities. That means even relatively young trees on your property may need a permit before removal.

The application process requires an arborist report, and the city charges a fee of $399.77 (including HST) for the first tree, plus $139.72 for each additional healthy tree. Dead or dying trees have no fee. Replanting requirements are tied directly to the size of the tree being removed: one replacement tree is required for every 15 cm of trunk diameter, and a security deposit is required. If you cannot replant on site, cash-in-lieu payments apply.

Mississauga's rapid development means tree permits often intersect with construction and site plan approvals. We work with property owners, developers, and contractors across the city to prepare reports that meet Mississauga's specific requirements and keep projects on schedule.
