Seaforth & Lansdowne

Traffic volume14-hour count · Mar 24, 2024 · weekend

The north leg carries the load — 3,688 southbound vehicles, or 42% of everything entering — while the east leg brought 204. The afternoon peak is the heavier one — 834 vehicles in the hour from 3:15 p.m., 36% above the morning peak from 9:30 a.m. (615). Heavy vehicles made up 2.6% of traffic (typical: 3.2%). The citywide median for a 14-hour count is 16,177 vehicles. The count was taken on a Sunday, so it reflects weekend traffic; the rankings compare it with weekday counts elsewhere. The count is 3 years old; the City recounts intersections on an ad-hoc schedule, so volumes may have shifted since.

Peak hours: 615 vehicles in the hour from 9:30 a.m. and 834 from 3:15 p.m. (approach figures are vehicles entering from that leg over the whole count — one day's traffic, not an annual average).

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.

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.

Each building links to its full record on LandlordReport.

Toronto Police place five thefts from vehicles and one bicycle theft at this intersection in 2016–2025 — about the median for an intersection with any reported theft. 40% of the vehicle thefts were from the street or other outdoor spots. Since January 2026, 1 more has been reported, the latest on May 16, 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 Roncesvalles.
