De Grassi & Dundas

Traffic volume8-hour count · Jul 8, 2020

This is a three-leg intersection with no north leg. Traffic is heaviest from the east: 3,217 westbound vehicles entered from that leg, 54% of the total, against 414 from the south. Most cyclists arrived from the east (398 of 794). Evening rush dominates here: 855 vehicles in the peak hour from 4:15 p.m., against 702 in the morning peak from 8:30 a.m. Trucks and buses were 7.9% 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 6 years old — treat it as a snapshot of 2020, 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: 702 vehicles in the hour from 8:30 a.m. and 855 from 4:15 p.m. (approach figures are vehicles entering from that leg over the whole count — one day's traffic, not an annual average).

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.

How fast traffic moves here

On Dundas St E between Wardell St and Logan Ave, 166 m from the corner, a 7-day count in June 2022 put the average speed at 40 km/h and the 85th-percentile speed at 48 km/h, with the fastest one in twenty at 52 km/h or more. That segment carries about 11,400 vehicles a day. The reading is 4 years old; the City counts on request rather than on a schedule.

At the school-zone speed sign on Dundas St E (132 m away, 40 km/h limit), 0.0% of the 11,385 vehicles logged in August 2026 were doing 50 km/h or more — almost none. 6 speed humps slow traffic on de Grassi Street between Queen St E and Dundas St E.

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 nine RentSafeTO-registered apartment buildings — 396 rental units — seven social or Toronto Community Housing. The nearest is 859 Dundas St E (406 m, 29 units, 4 storeys, built 1973), which scored 96 out of 100 at its December 2025 RentSafeTO evaluation. One building of the 9 scored below 70; the average is 86, below the 90 typical of Toronto intersections.

9 registered buildings · 396 units · 7 social housing · 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.

Six thefts from vehicles and one bike theft were reported around this corner in 2016–2025 — about the median for an intersection with any reported theft. 50% of the vehicle thefts were from the street or other outdoor spots. Since January 2026, 1 more has been reported, the latest on Jan 25, 2026.

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 South Riverdale.
