Tree Equity Score 2025 - Outer Urban

This layer displays calculated 2025 Tree Equity Scores for the Outer Urban Official Plan Transect. Other transects (Suburban/Outer Urban/Inner Urban/Downtown Core) are also available.

This layer displays calculated 2025 Tree Equity Scores for the Outer Urban Official Plan Transect. The layer was produced using a modified version of the American Forests methodology, where a Tree Canopy Goal was created based on a Transect-level building density calculation. Tree Equity Scores were calculated at the census tract level for all Official Plan designated residential areas within the urban boundary. Canopy cover was calculated using the 2022 Canopy Cover Assessment. The Priority Index was calculated using data from 2021 Census, 2019-2020 Canadian Community Health Survey, and 2022 Landsat thermal band imagery. More information on the methodology used to create the data can be found on the City of Ottawa website. 

This layer was produced by Climate Change and Resiliency Services, Strategic Initiatives Department, to guide the selection of priority areas for tree planting under the Tree Planting Strategy. 

Accuracy: Data are complete and there are no known issues. The Tree Equity Score analysis was created using 2021 census data to provide information on socio-economic and demographic data. Census data was combined with urban heat and canopy cover data to produce a Tree Equity Score. The analysis was performed only for urban, residential areas of the census tracts. Results of the analysis have been used to identify and prioritize areas of in need of tree canopy cover.
