PROVINCE OVERVIEW
Ontario tree-rule guides
Ontario tree rules are highly municipal. Some cities regulate larger private trees by diameter, while others focus on woodlots, protected areas or public trees.

Why the city source matters
A province-wide summary cannot decide whether a tree is private, municipal, boundary, protected by development conditions or inside a special area. Confirm the linked municipal source before pruning or removal.
