Duplex & Castlefield

Traffic volume14-hour count · Jun 4, 2024

Traffic is heaviest from the north: 3,931 southbound vehicles entered from that leg, 48% of the total, against 43 from the east. Most cyclists arrived from the north (227 of 445). The morning and afternoon peaks are nearly equal: 830 vehicles in the hour from 8:15 a.m. and 771 from 4:30 p.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 is 2 years old; the City recounts intersections on an ad-hoc schedule, so volumes may have shifted since.

Peak hours: 830 vehicles in the hour from 8:15 a.m. and 771 from 4:30 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 2024, with 3 collisions; 2025 recorded 2. 3 collisions (17%) involved an injury. 3 drivers failed to remain at the scene — 17% of collisions. None of the collisions in the window involved a pedestrian or cyclist. Since January 2026, 1 more collision has been reported; they sit outside the ranking window. The most recent report on file is from May 20, 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.

How fast traffic moves here

On Castlefield Ave between Duplex Ave and Rosewell Ave, 159 m from the corner, a 24-hour count in November 2012 put the average speed at 36 km/h and the 85th-percentile speed at 45 km/h, with the fastest one in twenty at 50 km/h or more. That segment carries about 1,400 vehicles a day. The reading is 14 years old; the City counts on request rather than on a schedule. Duplex Ave between Montgomery Ave and Roselawn Ave measured slower: 35 km/h on average and an 85th percentile of 42 km/h (Apr 2011). At the school-zone speed sign on Erskine Ave (250 m away, 30 km/h limit), 1.5% of the 91,477 vehicles logged in August 2026 were doing 40 km/h or more — a small minority.

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.

Within a kilometre there are 76 RentSafeTO-registered apartment buildings — 9,049 rental units, 5.1× the median for a Toronto intersection — ten social or Toronto Community Housing. The nearest is 487 Duplex Ave (170 m, 36 units, 3 storeys, built 1900), which scored 82 out of 100 at its December 2025 RentSafeTO evaluation. One building of the 76 scored below 70; the average is 92, about the citywide norm.

76 registered buildings · 9,049 units · 10 social housing · tallest 39 storeys. The score is the City's RentSafeTO evaluation out of 100; buildings of three or more storeys and ten or more units are registered, condominiums and houses are not. Each building links to its full record on LandlordReport.

Six 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. 50% of the vehicle thefts were from house driveways and garages.

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 Yonge-Eglinton.
