Trethewey & Martha Eaton

Traffic volume8-hour count · Mar 1, 2023

This is a three-leg intersection with no south leg. Traffic is heaviest from the east: 3,411 westbound vehicles entered from that leg, 51% of the total, against 336 from the north. Evening rush dominates here: 1,231 vehicles in the peak hour from 4:30 p.m., against 1,032 in the morning peak from 8:15 a.m. Trucks and buses were 5.5% of traffic, well above the typical 3.2% — a sign of a goods-movement or bus corridor. For scale, a typical counted intersection in Toronto sees 16,177 vehicles over 14 hours. The count is 4 years old — treat it as a snapshot of 2023, 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: 1,032 vehicles in the hour from 8:15 a.m. and 1,231 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 2018, with 12 collisions; 2025 recorded 6. 6 collisions (8%) involved an injury; the citywide share is 15%. 20 drivers failed to remain at the scene — 26% of collisions, a higher hit-and-run share than the city's 16%. 1 collision involved a pedestrian or cyclist (1%), a low share for a Toronto intersection. Since January 2026, 5 more collisions have been reported; they sit outside the ranking window. The most recent report on file is from Aug 29, 2026.

No one was killed or seriously injured here in 2016–2025, the ten complete years the rankings use. 1 earlier KSI collision is on file, the last on Apr 1, 2009.

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

On Trethewey Dr between Todd Baylis Blvd and Martha Eaton Way, 124 m from the corner, a 3-day count in May 2023 put the average speed at 49 km/h and the 85th-percentile speed at 58 km/h, with the fastest one in twenty at 63 km/h or more. That segment carries about 12,500 vehicles a day.

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 18 RentSafeTO-registered apartment buildings — 1,724 rental units — two social or Toronto Community Housing. The nearest is 15 Martha Eaton Way (191 m, 364 units, 23 storeys, built 1984), which scored 84 out of 100 at its July 2026 RentSafeTO evaluation. None scored below 70; the average is 86, below the 90 typical of Toronto intersections.

18 registered buildings · 1,724 units · 2 social housing · tallest 23 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.

36 thefts from vehicles and five bike thefts were reported around this corner in 2016–2025 — 6.8× the median for a Toronto intersection with any reported theft. The pace has been steady at around 4.1 a year. 64% of the vehicle thefts were from the street or other outdoor spots; 60% 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 Brookhaven-Amesbury.
