Heath & Tweedsmuir

Traffic volume8-hour count · Dec 15, 2021

The east leg carries the load — 2,105 westbound vehicles, or 47% of everything entering — while the north leg brought 240. The morning and afternoon peaks are nearly equal: 667 vehicles in the hour from 8:00 a.m. and 673 from 4:00 p.m. Heavy vehicles made up 1.5% of traffic (typical: 3.2%). The citywide median for a 14-hour count is 16,177 vehicles. The count is 5 years old — treat it as a snapshot of 2021, 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: 667 vehicles in the hour from 8:00 a.m. and 673 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).

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.

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.

93 registered apartment buildings with 5,623 rental units stand within a kilometre of the corner, five of them social or Toronto Community Housing — 6.2× the median for a Toronto intersection. The nearest is 250 Heath St W (42 m, 81 units, 17 storeys, built 1975), which scored 93 out of 100 at its September 2024 RentSafeTO evaluation. None scored below 70; the average is 90, about the citywide norm.

93 registered buildings · 5,623 units · 5 social housing · tallest 30 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 ten thefts from vehicles and 11 bicycle thefts at this intersection in 2016–2025 — 3.5× the median for a Toronto intersection with any reported theft. The pace has slowed: 4 in 2023–2025, about 1.3 a year, against 2.4 a year before that. 60% of the vehicle thefts were from the street or other outdoor spots; 91% 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 Forest Hill South.
