Toronto intersections with the most fatal collisions
Ranked by fatal collisions, recorded within 65 m of the intersection, 2016–2025 — the last ten complete years. 319 intersections have at least one. Counts, not blame: a high number can reflect volume as much as design, so daily vehicles are shown beside each.
#1 is Dundas & Sherbourne with 4 fatal collisions in 2016–2025.
What "dangerous" means here. Killed-or-seriously-injured (KSI) collisions are the most serious subset of all collisions; property-damage and minor-injury collisions are not included. Records can take a year or more to be finalized, so the most recent year is always incomplete — that's why the window ends in 2025.
