St Clair & Marsh

Traffic volume8-hour count · Apr 29, 2015

This is a three-leg intersection with no north leg. Traffic is heaviest from the east: 6,693 westbound vehicles entered from that leg, 50% of the total, against 72 from the south. Evening rush dominates here: 2,249 vehicles in the peak hour from 2:00 p.m., against 2,049 in the morning peak from 7:30 a.m. Trucks and buses were 5.1% of traffic, well above the typical 3.2% — a sign of a goods-movement or bus corridor. For scale, a typical counted intersection in Toronto sees 16,177 vehicles over 14 hours. The count is 12 years old — treat it as a snapshot of 2015, 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: 2,049 vehicles in the hour from 7:30 a.m. and 2,249 from 2:00 p.m. (approach figures are vehicles entering from that leg over the whole count — one day's traffic, not an annual average).

The most recent report on file is from Aug 16, 2026.

No collision involving a death or serious injury has been recorded within 65 m of this intersection since the record begins in 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.

Speeds here, last measured in 2019

On St Clair Ave E between Birchmount Rd and North Woodrow Blvd, 359 m from the corner, a 2-day count in September 2019 put the average speed at 64 km/h and the 85th-percentile speed at 72 km/h, with the fastest one in twenty at 78 km/h or more. That segment carries about 27,100 vehicles a day. The reading is 7 years old; the City counts on request rather than on a schedule.

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.

Police records place no theft from a vehicle or bicycle theft at this intersection in 2016–2025.

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 Clairlea-Birchmount.
