Dufferin & Martin Ross

Traffic volume14-hour count · Nov 30, 2023

Traffic is heaviest from the south: 10,767 northbound vehicles entered from that leg, 49% of the total, against 39 from the east. The morning and afternoon peaks are nearly equal: 3,090 vehicles in the hour from 8:15 a.m. and 3,015 from 4:00 p.m. Heavy vehicles made up 4.1% of traffic (typical: 3.2%). For scale, a typical counted intersection in Toronto sees 16,177 vehicles over 14 hours. The count is 3 years old; the City recounts intersections on an ad-hoc schedule, so volumes may have shifted since.

Peak hours: 3,090 vehicles in the hour from 8:15 a.m. and 3,015 from 4:00 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 19 collisions; 2025 recorded 18. 25 collisions (23%) involved an injury; the citywide share is 15%. 18 drivers failed to remain at the scene — 16% of collisions, in line with the citywide 16%. 2 collisions involved a pedestrian or cyclist (2%), a low share for a Toronto intersection. Since January 2026, 6 more collisions have been reported; they sit outside the ranking window. The most recent report on file is from Aug 20, 2026.

No one was killed or seriously injured here in 2016–2025, the ten complete years the rankings use. 1 earlier KSI collision is on file, the last on Jul 18, 2013.

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 Dufferin St between Martin Ross Ave and Supertest Rd, 155 m from the corner, a 2-day count in September 2019 put the average speed at 55 km/h and the 85th-percentile speed at 65 km/h, with the fastest one in twenty at 71 km/h or more. That segment carries about 31,200 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.

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 one bike theft were reported around this corner in 2016–2025 — about the median for an intersection with any reported theft. 57% of the vehicle thefts were from the street or other outdoor spots.

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 York University Heights.
