Saint-Jean-sur-Richelieu tree rules

Authorization is required for a tree at least 10 cm DBH measured 1.3 m above ground. Removing a cedar hedge does not require this authorization.

The City includes actions that cause death—such as topping, poisoning, damaging roots or burying the trunk/root area—not just cutting the trunk. Normal pruning does not require a certificate when it does not compromise survival.

Examples include dead/seriously diseased/irreversibly declining trees, real imminent danger or serious demonstrated damage, unavoidable conflict with an authorized project, or prescribed silvicultural work. Minor nuisances such as leaves, shade, pollen or surface roots without serious damage are not enough.

The City publishes a $75-per-tree fee when the tree sits within the footprint of an authorized proposed construction; other cases such as dead, diseased or dangerous trees are free. Typical processing is 10–15 business days once the application is complete and fees are paid.

Once issued, the authorization certificate is valid for 12 months.

Replacement is generally required. Deciduous replacements must be at least 50 mm stem diameter at stump height; conifers at least 2 m tall. The first five replacements are normally due within 12 months, with up to 24 months for additional required trees.

The trees must be clearly marked, the City must be notified at least two business days before work, and the permit must remain visible from the street during the work.
