Traffic volume14-hour count · Aug 19, 2026

Traffic is heaviest from the south: 5,661 northbound vehicles entered from that leg, 43% of the total, against 782 from the west. Evening rush dominates here: 1,502 vehicles in the peak hour from 4:45 p.m., against 814 in the morning peak from 7:30 a.m. Heavy vehicles made up 3.9% of traffic (typical: 3.2%).

Collisions 2016–2025 · within 65 m

The worst year was 2022, with 6 collisions; 2025 recorded 5. 10 collisions (32%) involved an injury; the citywide share is 15%. 4 drivers failed to remain at the scene — 13% of collisions, in line with the citywide 16%. 3 collisions involved a pedestrian or cyclist (10%) — a high share for a Toronto intersection. Since January 2026, 3 more collisions have been reported; they sit outside the ranking window. The most recent report on file is from Mar 12, 2026.

One collision in 2016–2025 left someone seriously injured; it was not fatal. 1 cyclist was among those hurt. It happened in daylight or lit conditions. The most recent was on Dec 13, 2021. The police all-collisions file records 1 fatal collision here in 2016–2025; the KSI file, which is compiled separately and geocoded to the nearest leg, places it just outside the 65 m radius.

A collision counts when its recorded location is within 65 m of the centreline node, intersection-related or not. KSI = killed or seriously injured, the basis of the danger rankings; records can lag a year or more, so the current year is outside the window. How collisions are counted.

Our own measure, not a licensed walkability rating: every point comes from a City dataset listed under Sources, and the six parts add up to the score. How the score is built · the full ranking.

Three thefts from vehicles and no bike thefts were reported around this corner in 2016–2025 — below the median of 6 for an intersection with any reported theft.

Police offset every occurrence to the nearest intersection before publishing, so these are thefts on the streets and premises around this node, not necessarily at the corner itself. Other offences are published by neighbourhood only — see Mount Olive-Silverstone-Jamestown.
