Grenville & Bay

Traffic volume8-hour count · Mar 28, 2017

Traffic is heaviest from the north: 5,054 southbound vehicles entered from that leg, 48% of the total, against 434 from the east. Most cyclists arrived from the north (551 of 896). The morning and afternoon peaks are nearly equal: 1,385 vehicles in the hour from 8:30 a.m. and 1,445 from 4:00 p.m. Heavy vehicles made up 4.3% of traffic (typical: 3.2%). For scale, a typical counted intersection in Toronto sees 16,177 vehicles over 14 hours. The count is 10 years old — treat it as a snapshot of 2017, 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: 1,385 vehicles in the hour from 8:30 a.m. and 1,445 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).

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

The City's most recent midblock count on Bay St between College St and Grenville St (43 m away, Mar 2021) recorded volume only — about 6,432 vehicles a day — with no speed data.

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 65 RentSafeTO-registered apartment buildings — 9,776 rental units, 4.3× the median for a Toronto intersection — 13 social or Toronto Community Housing. The nearest is 32 Grenville St (91 m, 50 units, 12 storeys, built 1900), which scored 100 out of 100 at its November 2025 RentSafeTO evaluation. None scored below 70; the average is 90, about the citywide norm.

65 registered buildings · 9,776 units · 13 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.

17 thefts from vehicles and 25 bike thefts were reported around this corner in 2016–2025 — 7.0× the median for a Toronto intersection with any reported theft. The pace has been steady at around 4.2 a year. 47% of the vehicle thefts were from apartment-building parking; 44% of the bike 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 Bay-Cloverhill.
