Martin Grove & Dewitt

Traffic volume14-hour count · Nov 29, 2023

This is a three-leg intersection with no east leg. Traffic is heaviest from the south: 3,146 northbound vehicles entered from that leg, 55% of the total, against 161 from the west. Evening rush dominates here: 1,105 vehicles in the peak hour from 4:00 p.m., against 919 in the morning peak from 7:45 a.m. Heavy vehicles made up 3.5% 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: 919 vehicles in the hour from 7:45 a.m. and 1,105 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).

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 Martin Grove Rd between Dewitt Rd and Winterton Dr, 348 m from the corner, a 3-day count in May 2026 put the average speed at 46 km/h and the 85th-percentile speed at 55 km/h, with the fastest one in twenty at 62 km/h or more. That segment carries about 9,800 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.

The nearest is 7 Richgrove Dr (854 m, 129 units, 11 storeys, built 1969), which scored 99 out of 100 at its November 2025 RentSafeTO evaluation. None scored below 70; the average is 96, above the 90 typical of Toronto intersections.

3 registered buildings · 494 units · tallest 22 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 no bike thefts were reported around this corner 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 Princess-Rosethorn.
