Trethewey & Todd Baylis

Traffic volume8-hour count · Mar 1, 2023

The east leg carries the load — 3,909 westbound vehicles, or 47% of everything entering — while the north leg brought 103. The morning and afternoon peaks are nearly equal: 1,271 vehicles in the hour from 8:15 a.m. and 1,364 from 4:30 p.m. Trucks and buses were 6.5% of traffic, well above the typical 3.2% — a sign of a goods-movement or bus corridor. The citywide median for a 14-hour count is 16,177 vehicles. 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: 1,271 vehicles in the hour from 8:15 a.m. and 1,364 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

2016 was the peak year (9 collisions), and 2025 closed with 5. 16% of collisions here involved an injury, in line with the 15% citywide. 7 drivers failed to remain at the scene — 13% of collisions, below the citywide 16%. People walking or cycling were involved in 5% of collisions here (citywide: 5%). Since January 2026, 6 more collisions have been reported; they sit outside the ranking window. The most recent report on file is from Jun 9, 2026.

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.

How fast traffic moves here

The City's counter on Trethewey Dr between Todd Baylis Blvd and Martha Eaton Way (121 m away) recorded an average of 49 km/h in its 3-day count in May 2023; 85% of drivers were at or under 58 km/h. 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.

24 registered apartment buildings with 1,411 rental units stand within a kilometre of the corner. The nearest is 15 Martha Eaton Way (223 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.

24 registered buildings · 1,411 units · 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.

Toronto Police place one theft from a vehicle and no bicycle thefts at this intersection in 2016–2025.

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.
