Most cyclists arrived from the north (557 of 1,365). The morning and afternoon peaks are nearly equal: 292 vehicles in the hour from 8:15 a.m. and 293 from 4:45 p.m. Heavy vehicles made up 3.5% 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: 292 vehicles in the hour from 8:15 a.m. and 293 from 4:45 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.

How fast traffic moves here

The City's counter on Brock Ave between Seaforth Ave and Florence St (171 m away) recorded an average of 35 km/h in its 7-day count in June 2022; 85% of drivers were at or under 43 km/h. That segment carries about 3,500 vehicles a day. The reading is 4 years old; the City counts on request rather than on a schedule. Seaforth Ave between Lane W of Brock and S of Seaforth and O'hara Ave measured slower: 19 km/h on average and an 85th percentile of 28 km/h (Sep 2026). At the school-zone speed sign on Dufferin St (338 m away, 30 km/h limit), 36% of the 266,392 vehicles logged in August 2026 were doing 40 km/h or more — a high share for a school zone.

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.

61 registered apartment buildings with 4,993 rental units stand within a kilometre of the corner, 18 of them social or Toronto Community Housing — 4.1× the median for a Toronto intersection.

One building of the 61 scored below 70; the average is 89, about the citywide norm.

61 registered buildings · 4,993 units · 18 social housing · tallest 20 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 two thefts from vehicles and four bicycle thefts at this intersection in 2016–2025 — about the median for an intersection with any reported theft.

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 Roncesvalles.
