Arborist Reports in Mississauga
An arborist report is a written assessment of a tree's condition, value or risk, prepared by a certified arborist and formatted to meet specific requirements. In Mississauga, arborist reports are required for tree removal permit applications, construction projects near protected trees, development applications, and certain legal disputes involving trees on shared property lines.
Our arborist has over 30 years of experience in the GTA and is ISA certified. He knows what the City of Mississauga requires in a report, what level planners expect for development applications, and how to structure risk assessments for legal or insurance purposes. When you need a report that will actually be accepted, this is the experience level that matters.
When You Need an Arborist Report in Mississauga
Tree Removal Permits
Mississauga requires an arborist report as part of the permit application when removing trees 15cm diameter or larger on private property. The report must document the species, size, condition and the reason for removal. For dead or hazardous trees the report supports the application. For healthy trees the bar is higher the report needs to justify removal on condition or site-related grounds. We prepare these reports regularly and know exactly what the City needs to see.
Construction and Renovation Projects
If you are adding an addition, building a detached garage, replacing a driveway, or doing any significant excavation near protected trees, Mississauga building permit requirements will likely require an arborist report before the permit is issued. The report assesses which trees are within the construction impact zone, what protection measures are required during construction, and what the post-construction monitoring plan looks like. Getting this report done early in your planning process can save you from redesigning the project later.
Development Applications
Larger development projects severances, rezoning applications, site plan approvals require a detailed tree inventory and preservation plan as part of the submission package. This involves identifying, tagging and assessing every tree on or near the subject property, classifying them by condition and significance, and providing a detailed plan for which trees will be retained and protected through construction. Our arborist has prepared these reports for residential and commercial development applications across the GTA.
Private Risk Assessments
You do not need a permit application to get an arborist report. Many Mississauga homeowners commission risk assessments on their own trees when they are concerned about structural integrity particularly after storm damage, after a hard winter, or when they notice something that looks wrong. A written risk assessment documents the condition of the tree and the recommended action, which is also useful for insurance purposes if a claim ever arises.
Neighbour and Boundary Tree Disputes
Disputes about trees on or near property lines sometimes require an independent arborist assessment to establish the facts. Who owns the tree, what condition is it in, is it a risk, what value does it have these are questions a written arborist report can help resolve. We provide neutral, professional assessments in these situations.
What Our Arborist Reports Include
Every report is formatted to meet the requirements of its specific purpose. A permit support report is different from a construction impact assessment, which is different from a risk assessment. The core elements in most reports include: site and tree location description, species identification, diameter at breast height (measured at 1.4m per ISA standard), crown spread and height, overall condition rating, structural assessment, relevant defects or concerns, and recommendations with supporting rationale.
Reports are delivered as a signed PDF document from the certifying arborist. We include site photos, a simple site plan sketch where required, and any supporting data the application or project needs. Turnaround time is typically five to seven business days from the site visit, faster for urgent situations.
Other Arborist Report Types
Beyond permit reports and risk assessments, our ISA certified arborist prepares several other types of documentation. Tree appraisal reports establish the monetary value of a tree using ISA trunk formula or comparable methods, used for insurance claims, property disputes, and litigation support. Remedial Work Reports address Orders to Comply issued by the municipality, documenting current tree conditions and outlining practical mitigation steps that satisfy the compliance requirement. Exploratory root excavation reports document root location, depth and proximity to foundations or utilities using air spade or hand excavation where the underground situation needs to be physically confirmed before construction or engineering decisions are made. If your situation requires documentation not listed here, contact us to confirm what format is needed before booking a site visit.

Does Mississauga require an arborist report for every tree removal permit?
Yes, an arborist report is required as part of every private tree removal permit application in Mississauga for trees 15cm diameter or larger. The City will not process the permit application without it. The report must be prepared by a certified arborist and must document the species, size and condition of the tree being removed.
Can you prepare the permit application as well as the report?
Yes. We can prepare the arborist report and manage the permit application submission on your behalf. This is the easier option for most homeowners we know the City's system, we know the format they want, and we handle the back-and-forth if the City has questions about the application.
Will my arborist report be accepted by the City of Mississauga?
Our reports are prepared by an ISA certified arborist with over 30 years of GTA experience and are formatted to meet City of Mississauga requirements. We have not had a report rejected on format or content grounds. If the City has follow-up questions we respond to them as part of the service.
