St Clair & Tweedsmuir

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

This is a three-leg intersection with no south leg. Traffic is heaviest from the east: 7,890 westbound vehicles entered from that leg, 50% of the total, against 692 from the north. Most cyclists arrived from the west (183 of 352). Evening rush dominates here: 1,379 vehicles in the peak hour from 5:30 p.m., against 1,124 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: 1,124 vehicles in the hour from 9:30 a.m. and 1,379 from 5:30 p.m. (approach figures are vehicles entering from that leg over the whole count — one day's traffic, not an annual average).

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

On Tweedsmuir Ave between St Clair Ave W and Heath St W, 142 m from the corner, a 3-day count in September 2020 put the average speed at 26 km/h and the 85th-percentile speed at 34 km/h, with the fastest one in twenty at 39 km/h or more.
