Bay & St Mary

Traffic volume14-hour count · Oct 9, 2025

The north leg carries the load — 8,207 southbound vehicles, or 46% of everything entering — while the east leg brought 764. Most cyclists arrived from the north (1,028 of 2,201). The afternoon peak is the heavier one — 1,543 vehicles in the hour from 5:15 p.m., 20% above the morning peak from 9:00 a.m. (1,291). Heavy vehicles made up 3.1% of traffic (typical: 3.2%). The citywide median for a 14-hour count is 16,177 vehicles. The count is 13 months old; the City recounts intersections on an ad-hoc schedule, so volumes may have shifted since.

Peak hours: 1,291 vehicles in the hour from 9:00 a.m. and 1,543 from 5:15 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

2019 was the peak year (13 collisions), and 2025 closed with 5. 17% of collisions here involved an injury, in line with the 15% citywide. 13 drivers failed to remain at the scene — 19% of collisions, in line with the citywide 16%. People walking or cycling were involved in 11% of collisions here (citywide: 5%). Since January 2026, 4 more collisions have been reported; they sit outside the ranking window. The most recent report on file is from Aug 13, 2026.

The KSI record for this intersection is empty back to 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.

Speeds here, last measured in 2019

The City's counter on St Mary St between St Nicholas St and La Scala Lane (100 m away) recorded an average of 23 km/h in its 3-day count in May 2019; 85% of drivers were at or under 32 km/h. That segment carries about 2,500 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.

68 registered apartment buildings with 8,674 rental units stand within a kilometre of the corner, five of them social or Toronto Community Housing — 4.5× the median for a Toronto intersection. The nearest is 1101 Bay St (36 m, 265 units, 28 storeys, built 1979), which scored 87 out of 100 at its June 2026 RentSafeTO evaluation. Two buildings of the 68 scored below 70; the average is 88, about the citywide norm.

68 registered buildings · 8,674 units · 5 social housing · tallest 51 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.

Toronto Police place 14 thefts from vehicles and six bicycle thefts at this intersection in 2016–2025 — 3.3× the median for a Toronto intersection with any reported theft. The pace has picked up: 10 in 2023–2025, about 3.3 a year, against 1.4 a year before that. 50% of the vehicle thefts were from apartment-building parking; 83% of the bike thefts were from the street or other outdoor spots. Since January 2026, 1 more has been reported, the latest on Jan 19, 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 Bay-Cloverhill.
