Traffic and safety
The City's latest turning-movement count, every police-reported collision within 65 m, speeds on these streets
Traffic volume8-hour count · Dec 9, 2021
The west leg carries the load — 6,260 eastbound vehicles, or 51% of everything entering — while the north leg brought 260. The afternoon peak is the heavier one — 1,860 vehicles in the hour from 4:30 p.m., 21% above the morning peak from 8:30 a.m. (1,540). Heavy vehicles made up 4.3% of traffic (typical: 3.2%). The citywide median for a 14-hour count is 16,177 vehicles. The count is 5 years old — treat it as a snapshot of 2021, not today's volume. It was an 8-hour count, which is not directly comparable with the 14-hour counts the City has used since September 2023.
Peak hours: 1,540 vehicles in the hour from 8:30 a.m. and 1,860 from 4:30 p.m. (approach figures are vehicles entering from that leg over the whole count — one day's traffic, not an annual average).
Collisions 2016–2025 · within 65 m
2017 was the peak year (2 collisions), and 2025 closed with 1. 0% of collisions here involved an injury. 1 driver failed to remain at the scene — 13% of collisions. None of the collisions in the window involved a pedestrian or cyclist. Since January 2026, 1 more collision has been reported; they sit outside the ranking window. The most recent report on file is from Sep 25, 2026.
The KSI record for this intersection is empty back to 2006.

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.
How fast traffic moves here
The City's counter on St Clair Ave W between Castleton Ave and Mould Ave (285 m away) recorded an average of 55 km/h in its 3-day count in October 2022; 85% of drivers were at or under 64 km/h. That segment carries about 24,500 vehicles a day. The reading is 4 years old; the City counts on request rather than on a schedule. Mariposa Ave between Lane N of St Clair and E of Mariposa and Pritchard Ave measured slower: 33 km/h on average and an 85th percentile of 43 km/h (Apr 2019). At the school-zone speed sign on Priscilla Ave (352 m away, 30 km/h limit), 3.3% of the 6,966 vehicles logged in August 2026 were doing 40 km/h or more — a small minority.
