The morning and afternoon peaks are nearly equal: 548 vehicles in the hour from 8:15 a.m. and 566 from 5:15 p.m. Heavy vehicles made up 2.5% of traffic (typical: 3.2%). The citywide median for a 14-hour count is 16,177 vehicles. The count is recent, so it reflects current conditions.

Peak hours: 548 vehicles in the hour from 8:15 a.m. and 566 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).

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.

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.

19 registered apartment buildings with 839 rental units stand within a kilometre of the corner, one of them social or Toronto Community Housing. The nearest is 456 Palmerston Blvd (141 m, 32 units, 4 storeys, built 1904), which scored 81 out of 100 at its August 2025 RentSafeTO evaluation. One building of the 19 scored below 70; the average is 86, below the 90 typical of Toronto intersections.

19 registered buildings · 839 units · 1 social housing · tallest 24 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 eight thefts from vehicles and nine bicycle thefts at this intersection in 2016–2025 — 2.8× the median for a Toronto intersection with any reported theft. The pace has been steady at around 1.7 a year. 88% of the vehicle thefts were from the street or other outdoor spots; 44% of the bike thefts were from apartment-building parking.

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 Palmerston-Little Italy.
