Tree removal rules in Richmond Hill, ON
A plain-English guide to what Richmond Hill publishes about tree removal and protection. The first question is whether the rule covers your private tree at all—not every City tree bylaw is a private-yard permit bylaw.
CITY-SPECIFIC SUMMARY
What Richmond Hill actually regulates
Richmond Hill’s published tree and bylaw rules, in plain English:
Richmond Hill requires a permit before injuring or removing a private tree with a diameter of 15 cm or more measured at 1.4 m above grade.
The Tree Preservation By-law also covers injury, so roots, grading and construction around a protected tree can matter even when removal is not planned.
Regional context
Richmond Hill applies its own municipal tree rules within Ontario. See the Ontario tree-rule overview for province-wide context; this page focuses on the ownership, diameter and site rules published for Richmond Hill.

Open Richmond Hill’s rule ↗City / boulevard tree
Do not self-authorizeIf the trunk is on Richmond Hill municipal land, a boulevard or road allowance, do not self-authorize pruning or removal. Confirm ownership and use the municipality’s tree process.
Check ownership rules ↗Boundary tree
Ownership mattersIf the trunk sits on or very near a property line in Richmond Hill, confirm ownership before work. Municipal tree rules do not replace private-law rights involving a co-owned or neighbouring tree.
