Tree Canopy Study
The City of Toronto is conducting a forestry inventory called the Tree Canopy Study. The purpose of this project is to better understand the trees, shrubs, and other kinds of vegetation which provide valuable health and social benefits to the citizens of Toronto.

The results of this plot-based sample inventory will be compared to a previous survey undertaken in 2008. Analysis of survey results will provide information on significant changes over the ten-year period between surveys and help us manage our urban forests.

In order to accomplish this survey, 412 sample plots have been randomly identified around the City in order to collect data and information about the status of trees and vegetation. Some of these plots are located in residential areas, some in business areas, as well as in parks and other open spaces. Urban Forestry has contracted BioForest Technologies Inc. to undertake this data collection. BioForest will send crews (consisting of two people per crew) around the City this summer to record the number, size and condition of trees and shrubs within each plot.

To carry out this study, a using a software tool called i-Tree (see http://www.itreetools.org/) is used.

Data collection will take place between late May and late August when the trees are in full foliage. Surveys will take place between the hours of 8:00 a.m. and 4:00 p.m. Monday to Friday. Prior to entering a property, crews will knock on the door and advise occupants of their presence on the property. They will possess an identification tag. Under no circumstance will there by any need for the crew members to enter your residence.


The City of Toronto has an estimated 10.2 million trees, the majority of which are on private property (6.1 million). There are approximately 600,000 street trees and 3.5 million trees in parks and ravines.

Urban Forestry maintains approximately 600,000 street trees and 3.5 million trees in parks and ravines.
