St Clair & Mould

Traffic volume14-hour count · Oct 18, 2025 · weekend

Traffic is heaviest from the east: 8,699 westbound vehicles entered from that leg, 38% of the total, against 889 from the north. Most cyclists arrived from the west (80 of 196). Evening rush dominates here: 2,041 vehicles in the peak hour from 2:15 p.m., against 1,653 in the morning peak from 9:30 a.m. Heavy vehicles made up 1.3% of traffic (typical: 3.2%). For scale, a typical counted intersection in Toronto sees 16,177 vehicles over 14 hours. The count was taken on a Saturday, so it reflects weekend traffic; the rankings compare it with weekday counts elsewhere. This is a fresh count, taken within the last year.

Peak hours: 1,653 vehicles in the hour from 9:30 a.m. and 2,041 from 2:15 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

The worst year was 2022, with 16 collisions; 2025 recorded 10. 11 collisions (12%) involved an injury; the citywide share is 15%. 14 drivers failed to remain at the scene — 15% of collisions, in line with the citywide 16%. 6 collisions involved a pedestrian or cyclist (6%), typical for the city. Since January 2026, 7 more collisions have been reported; they sit outside the ranking window. The most recent report on file is from Aug 30, 2026.

One collision in 2016–2025 left someone seriously injured; it was not fatal. 1 pedestrian was among those hurt. It happened in daylight or lit conditions. The most recent was on Feb 27, 2025. Going back to 2006, the total is 3.

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.

Speeds here, last measured in 2022

On St Clair Ave W between Castleton Ave and Mould Ave, 56 m from the corner, a 3-day count in October 2022 put the average speed at 55 km/h and the 85th-percentile speed at 64 km/h, with the fastest one in twenty at 69 km/h or more. 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. 3 speed humps slow traffic on Mould Avenue between St Clair Ave W and Pritchard Ave.

Midblock counts are automatic counters laid across the road for one to seven days; 85% of drivers were at or below the 85th-percentile speed. A reading is not the speed through the intersection itself, and posted limits are not in the count data. How speeds are read.

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.

Seven thefts from vehicles and no bike thefts were reported around this corner in 2016–2025 — about the median for an intersection with any reported theft. 71% of the vehicle thefts were from the street or other outdoor spots. Since January 2026, 3 more have been reported, the latest on Apr 27, 2026.

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 Rockcliffe-Smythe.
