Peel Region and Halton Region publish no incident-level open data feed, so they are not in this table — the map covers them through police news releases, local news and community reports instead.
What counts as assault
In Toronto and Durham it is the category “Assault”; in York Region, “Assaults”. It is the largest single category in the GTA's open data, and it spans a wide range of severity — from minor altercations to serious attacks — which the source data does not separate on the map. A high count here is not, by itself, a measure of how dangerous a place feels.
How the map shows it
On the live map, assault reports carry the pink Assault marker and its own filter chip — the button above opens the map with every other type switched off, so you see only this type. Zoom into a city or drop a pin with “Near me” and the panel counts only what is inside your ring and your date range.
