Dundas & Markham

Traffic volume14-hour count · Nov 14, 2023

Traffic is heaviest from the east: 5,505 westbound vehicles entered from that leg, 49% of the total, against 5 from the south. Most cyclists arrived from the west (822 of 1,659). Evening rush dominates here: 1,075 vehicles in the peak hour from 4:30 p.m., against 824 in the morning peak from 8:00 a.m. Heavy vehicles made up 1.6% of traffic (typical: 3.2%). For scale, a typical counted intersection in Toronto sees 16,177 vehicles over 14 hours. The count is 3 years old; the City recounts intersections on an ad-hoc schedule, so volumes may have shifted since.

Peak hours: 824 vehicles in the hour from 8:00 a.m. and 1,075 from 4:30 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

The worst year was 2016, with 11 collisions; 2025 recorded 7. 10 collisions (14%) involved an injury; the citywide share is 15%. 10 drivers failed to remain at the scene — 14% of collisions, in line with the citywide 16%. 9 collisions involved a pedestrian or cyclist (13%) — a high share for a Toronto intersection.

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.

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 18 RentSafeTO-registered apartment buildings — 1,005 rental units — nine social or Toronto Community Housing. The nearest is 115 Euclid Ave (443 m, 16 units, 3 storeys, built 1930), which scored 88 out of 100 at its July 2026 RentSafeTO evaluation. None scored below 70; the average is 84, below the 90 typical of Toronto intersections.

18 registered buildings · 1,005 units · 9 social housing · tallest 14 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.

Four thefts from vehicles and six bike thefts were reported around this corner in 2016–2025 — about the median for an intersection with any reported theft. The pace has slowed: 1 in 2023–2025, about 0.3 a year, against 1.3 a year before that. 33% 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 Trinity-Bellwoods.
