In 2024, Oakville staff wrote a report promising council “metrics regarding the number of issued removal permits.” Read all twelve pages and the metric never shows up. It does report how many trees came down before and after the town’s 2017 bylaw, how many replacements were planted instead of paid for, and the split council had in front of it when it changed the cash-in-lieu rules at the same meeting.
Oakville Publishes No Tree-Permit Statistics
There is no annual report on Oakville’s Private Tree Protection By-law. There is no open dataset of permit outcomes. The town’s public data portal carries a “Trees” layer with over 217,000 records, but it covers street and park trees the town owns, not the private removals the bylaw regulates. A separate ArcGIS layer tracks live permit applications, useful for checking a specific address, but it holds a rolling window of roughly the past twelve months and keeps no history: as of August 10, 2026, it showed 867 permits.
Oakville isn’t unusual here. Toronto, Mississauga, and Burlington publish nothing shaped like tree-permit statistics either. The closest thing Toronto ever published, a street-tree dataset, is now marked retired. The only reason anyone outside a planning department has ever seen permit-level data for any of these cities is an academic study, published in Arboriculture and Urban Forestry, that requested Toronto’s raw records directly, tree by tree, because no public version existed to download.
One Report, One Data Source
The single exception for Oakville is a March 2024 staff report to council, built on a consultant study by the University of Toronto and the Ontario Woodlot Association using LiDAR and GIS canopy modelling. It was commissioned to check the bylaw’s performance against the town’s 40 percent canopy-by-2057 target, not to become a public statistics release, and it shows in how the numbers are presented: two aggregated six-year windows, 2011 to 2016 and 2018 to 2023, with 2017 itself dropped from both sides as the transition year the bylaw took effect.
Removals excluding high-risk, ash, and dead trees fell from 7,789 in the earlier window to 4,718 in the later one, a 39 percent decline. Canopy removed over the same comparison fell further, from 379,758 to 166,678 square metres, a 56 percent drop.
Canopy loss falling faster than the removal count means the average removed tree got smaller: 48.8 square metres of canopy per tree in the earlier window against 35.3 in the later one. The report does not explain that shift.
Where the Replacement Trees Went
Every approved removal in Oakville can come with a replanting condition, sized by a stepped table that runs roughly one replacement tree per 10 centimetres of trunk diameter removed. The report’s replacement-condition count rose from 232 in the earlier window to 10,566 in the later one, close to a 45-fold increase.
For the later window, the report splits the 10,566 required replacements into trees planted and cash paid.
Within the current window, 5,127 replacements were planted and 5,439, or 51.5 percent, became cash payments instead.
Why Council Tightened Cash-in-Lieu the Same Meeting
Council received this report on March 25, 2024, and at that same meeting approved a procedure restricting cash-in-lieu to cases where a property has no room left to plant. Just under half of the required replacement trees were planted, and the rest became payments to the town.
Trees preserved through consultation and site visits, meaning removals avoided through consultation and a site visit with the town’s Forestry Services staff rather than a permit condition, rose from 2 in the earlier window to more than 345 in the later one. The town went from almost never talking a homeowner out of a removal to doing it several dozen times a year on average.
No follow-up report has been published since March 2024. Staff committed only to updating council “in future private tree protection by-law updates,” with no set schedule.

Get the replacement plan right in the first submission and the application stays out of a cash-in-lieu conversation with the town. The Arborist Group prepares tree removal reports for Oakville applications, sized against the bylaw’s stepped replacement table before the application goes in, not after a reviewer sends it back.
