GET THE SCOPE RIGHT
Start with assessment, then choose the response.
Risk depends on the likelihood of failure and what could be affected. Ask the assessing professional to explain the concern, practical options and any recommended urgency. Removal, pruning, further investigation or monitoring may be discussed; the appropriate approach requires site-specific judgement.
Do not enter an unsafe area to measure the trunk, inspect roots or take photographs.
Guelph tree permit guidance →Common questions
Does calling a tree hazardous make it permit-exempt?
No. The City lists exemptions, including certain high-risk situations with professional certification. Ask City staff how the exemption applies and what documentation is needed.
Can you assess a tree from my description?
A description can help route an enquiry but cannot establish safety. Arrange an appropriate on-site assessment and keep clear of any immediate hazard.
Local requirements: City of Guelph tree permit guidance. Your property’s circumstances determine what applies.
