Atlas & St Clair

Traffic volume8-hour count · Apr 16, 1991

This is a three-leg intersection with no south leg. Traffic is heaviest from the west: 6,619 eastbound vehicles entered from that leg, 50% of the total, against 337 from the north. The morning and afternoon peaks are nearly equal: 1,938 vehicles in the hour from 8:15 a.m. and 1,859 from 4:00 p.m. Heavy vehicles made up 4.5% of traffic (typical: 3.2%). For scale, a typical counted intersection in Toronto sees 16,177 vehicles over 14 hours. The count is 36 years old — treat it as a snapshot of 1991, 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: 1,938 vehicles in the hour from 8:15 a.m. and 1,859 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 peak year was 2025, the most recent in the window, with 8 collisions. 6 collisions (11%) involved an injury; the citywide share is 15%. 15 drivers failed to remain at the scene — 27% of collisions, a higher hit-and-run share than the city's 16%. 4 collisions involved a pedestrian or cyclist (7%) — a high share for a Toronto intersection. Since January 2026, 5 more collisions have been reported; they sit outside the ranking window. The most recent report on file is from Sep 18, 2026.

One collision in 2016–2025 left someone seriously injured; it was not fatal. It involved vehicle occupants only — no pedestrian or cyclist. It happened in darkness. The most recent was on Feb 1, 2020. 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.

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 35 RentSafeTO-registered apartment buildings — 1,313 rental units, 2.3× the median for a Toronto intersection — six social or Toronto Community Housing. The nearest is 795 St Clair Ave W (64 m, 19 units, 3 storeys, built 1929), which scored 94 out of 100 at its August 2026 RentSafeTO evaluation. None scored below 70; the average is 90, about the citywide norm.

35 registered buildings · 1,313 units · 6 social housing · tallest 19 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 ten bike thefts were reported around this corner in 2016–2025 — 2.7× the median for a Toronto intersection with any reported theft. The pace has picked up: 9 in 2023–2025, about 3.0 a year, against 1.0 a year before that. 83% of the vehicle thefts were from the street or other outdoor spots; 60% of the bike thefts were from apartment-building parking. Since January 2026, 2 more have been reported, the latest on Jun 21, 2026.

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 Wychwood.
