Canada-wide tree rule guide
Dead & hazard trees
A dead or hazardous tree is often treated differently, but it does not automatically mean “no permit.”
What to check.
Some cities offer an exemption, declaration or simplified application. Others still require a permit or evidence from an arborist. Emergency work can also have its own notification process.
Why there is no national yes/no answer.
Canadian municipalities use very different systems. Some regulate most larger private trees. Some regulate only woodlots, environmental lands or development sites. Others focus almost entirely on public trees. The city guide is where Tree Rules Canada publishes the local source-derived answer.
Research note
This page explains a research process, not legal or arboricultural advice. Confirm the current rule with the municipality and use a qualified arborist where tree health or structural risk is in question.
