Mississauga has one of the strictest tree protection bylaws in the GTA. Here's what homeowners need to know before removing a tree.
Mississauga's tree protection bylaw has a 15 cm diameter threshold — one of the lowest in the GTA. This means more trees on your property are likely protected compared to neighbouring cities like Toronto (30 cm) or Brampton (30 cm).
A permit is required to remove any private tree with a trunk diameter of 15 cm or more, measured at 1.4 metres above ground. This includes dead or dying trees — you still need a permit, though the fees are waived for those cases.
Trees in interior courtyards are not exempt from the permit process. Replacement trees, regardless of size, also cannot be injured or removed without a permit.
An ISA certified arborist report is required for all permit applications. The report assesses the tree's health, condition, structural integrity, and vigor. The only exceptions are for trees that are clearly dead, hazardous, or confirmed infected with Emerald Ash Borer.
Mississauga requires one replacement tree for every 15 cm of diameter of the tree being removed. For example, removing a 45 cm tree means planting 3 replacement trees. If you can't plant on your property, you may be able to pay cash-in-lieu.
Get your arborist report prepared. It must document the tree species, diameter, health condition, and reason for removal.
