Tree removal rules in Caledon, ON
A plain-English guide to what Caledon 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 Caledon actually regulates
Caledon’s published tree and bylaw rules, in plain English:
Caledon's Tree Preservation By-law that took effect in 2026 regulates specified private trees outside woodlands, including trees at or above its 30 cm diameter threshold.
The Town provides exemptions for circumstances such as some dead or hazardous trees, but owners still need to use the current bylaw process to determine whether an exemption applies.
Regional context
Caledon 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 Caledon.

Construction and tree protection in Caledon
The source reviewed for Caledon does not justify assuming that ordinary yard construction is always outside tree rules. If work could affect a City tree, boundary tree, protected area or a tree retained through development approval, confirm the municipal requirements before excavation or root disturbance.

Open Caledon’s rule ↗City / boulevard tree
Do not self-authorizeIf the trunk is on Caledon 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 Caledon, confirm ownership before work. Municipal tree rules do not replace private-law rights involving a co-owned or neighbouring tree.
Check local application rules ↗Development site
Often stricterIn Caledon, development work such as demolition, additions or subdivision can bring tree-retention, arborist or replacement requirements into the approval path; use the linked development-tree source for the site.
