Ottawa Arborist Reports

Tree Information Reports for City of Ottawa tree permits, infill building permits and tree assessments

An arborist report in Ottawa is what the City calls a Tree Information Report. You need one to remove a private tree 30 cm or more across on an urban lot of one hectare or less, to remove a City tree, or for infill development. Tree King's arborists write the report and handle the removal once the permit is issued. Call 613-627-2017 for a free quote.

When you need an arborist report

Ottawa's Tree Protection By-law (2020-340) came into effect on January 1, 2021. Under it, a City tree permit application is a Tree Information Report prepared by an arborist, submitted online with the permit fee. You need one when you are:

  • Removing a distinctive tree: a private tree 30 cm or more in diameter at 1.3 m above the ground, on a lot of one hectare or less inside the urban area.
  • Removing a City-owned tree, anywhere in Ottawa.
  • Building infill: a report is required with Committee of Adjustment and building permit applications for infill in the urban area.
  • Relying on the dead-tree exemption, which applies to a tree that is dead as confirmed by an arborist. A photo alone is weaker evidence than a written confirmation.

Not sure if your tree counts? We will tell you first whether it needs a permit at all. The full rules, fees and exemptions are in our guide to Ottawa tree removal permits.

Tree Information Reports

Short report or full report?

Schedule C of the by-law sets out two versions. A short report covers a removal with no development involved: the location, species, size, ownership and condition of each tree, the reason for removing it, and the arborist's recommendation. A full report for infill development adds site plans, protection measures for the trees being kept, boundary tree consent and replacement trees. Where a removal is justified by the tree's condition, the City can ask for more detail, including a tree risk assessment.

For everything that goes into each version, read when you need an arborist report in Ottawa.

Arborist assessments when you are not removing anything

A permit is not the only reason to have a tree looked at. An assessment is worth it if you:

  • Have a large tree near your house, your neighbour's property or the sidewalk and want to know whether it is a risk.
  • Notice signs of a sick tree, such as fungus growing on it, discoloured leaves or dead branches.

A tree can look healthy and still have problems that only get worse if nobody deals with them. An arborist is trained to spot them while they are small, so you can treat the tree and keep it instead of losing it.

Tree King prepares Tree Information Reports for Ottawa homeowners and, once the permit is issued, does the work too: tree removal, pruning and stump grinding. One company answers the permit question, writes the report and takes the tree down, anywhere in the City of Ottawa. See the areas we serve.

Arborist report questions

Frequently Asked Questions

In Ottawa's urban area, removing a private tree 30 cm or more across (measured 1.3 m up the trunk) on a lot of one hectare or less needs a City permit, and the application is a Tree Information Report written by an arborist. Removing a City-owned tree needs one anywhere in the city, and so does infill development.

The main exceptions are a tree that is an immediate threat to public health and safety, an ash tree infested with emerald ash borer, and a tree that is dead as confirmed by an arborist. Larger and rural properties follow different rules, covered in our Ottawa tree removal permit guide.
