Trethewey & Irving

Traffic volume8-hour count · Feb 28, 2023

Traffic is heaviest from the north: 3,944 southbound vehicles entered from that leg, 58% of the total, against 225 from the west. The morning and afternoon peaks are nearly equal: 1,200 vehicles in the hour from 8:00 a.m. and 1,135 from 4:15 p.m. Trucks and buses were 5.7% 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 4 years old — treat it as a snapshot of 2023, 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: 1,200 vehicles in the hour from 8:00 a.m. and 1,135 from 4:15 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 2019, with 10 collisions; 2025 recorded 4. 12 collisions (24%) involved an injury; the citywide share is 15%. 4 drivers failed to remain at the scene — 8% of collisions, below the citywide 16%. 2 collisions involved a pedestrian or cyclist (4%), typical for the city. Since January 2026, 3 more collisions have been reported; they sit outside the ranking window. The most recent report on file is from May 31, 2026.

Neither of the two serious-injury collisions in 2016–2025 was fatal. 1 cyclist and 1 motorcyclist were among those hurt. Both happened in darkness. The most recent was on Jul 13, 2018. 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.

How fast traffic moves here

On Trethewey Dr between Yore Rd and Yorktown Dr, 112 m from the corner, a 3-day count in May 2023 put the average speed at 47 km/h and the 85th-percentile speed at 54 km/h, with the fastest one in twenty at 59 km/h or more. That segment carries about 10,700 vehicles a day. Irving Rd between Keele St and Greenacres Rd measured slower: 39 km/h on average and an 85th percentile of 47 km/h (Apr 2019).

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.
