Why this park works

Ashbridges Bay Park works because its amenity diversity score (27) is in the top tier.

What limits this park

Ashbridges Bay Park is held back by enclosure (24, bottom quartile)— no mid-rise frontage to provide eyes on the park; border-vacuum risk is also elevated (100).

Most distinctive characteristic

Most distinctive feature: exceptionally low enclosure (24, bottom quartile).

Jacobs reading

Ashbridges Bay Park is currently underperforming on both axes — neither integrated into the city nor offering deep natural respite. A candidate for design intervention.

Performance in context

  • Strong underperformer relative to its cohort — raw 24 vs an expected 37 (gap -13).

0.0 / 100

Within 100 m of the park edge: 0 active uses (none) and 5 dead/hostile uses (parking_lot, highway). Active edges keep "eyes on the park" through the day; parking lots, blank institutional walls, rail and highway frontages drain street life.

Connectivity

51.6 / 100

Connectivity blends paths, intersections, transit, entrances, and edge density. This park has 65 mapped paths/walkways and 93 sidewalk segments within 50 m; 8 street intersections within 100 m; 1 transit stops within a 400 m walk; 12 estimated access points across ~4,732 m of perimeter. low edge density — significant superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity

20% weightmeasured 75%
27.3 / 100

3 distinct amenity types in the park (fitness, picnic, washroom). Diversity, not raw count, drives the score so a park with many distinct activity types can outrank a larger park that repeats the same use.

19 buildings within 25 m of the park edge (0 mid-rise, 19 low-rise, 0 tower); avg edge height 3.5 m (~1 floors); 0.4 buildings per 100 m of 4,732 m perimeter — thin frontage — significant blank-edge share; edges are barely there or single-storey; no towers immediately adjacent. "Eyes on the park" come strongest from the 0 mid-rise edge buildings.

Border Vacuum Risk

100.0 risk

Border-vacuum factors within 50 m of the park: parking_lot, Lake Shore Boulevard East, Emdaabiimok Avenue, Lake Shore Boulevard East. Jacobs warned that highways, rail, parking lots and blank institutional edges act as "vacuums" — they suppress foot traffic and isolate the park from its neighbourhood.

Human activity signals — not available

No activity signals have landed for this park yet. The model has scored its physical form but it can’t yet say how often it’s programmed, photographed, or walked through. See /data-ethics for what we will and will not collect.

Does this score feel accurate?

Your read of Ashbridges Bay Parkmatters. We’re testing whether the model lines up with how people actually use the park. Submissions are stored locally; no account needed.

Tell us how this park feels

We measure structure (canopy, edges, connectivity). You measure feeling. Both matter — and disagreement is itself useful civic data.

Rate this park on as many dimensions as you have an opinion about. 1 = not at all · 5 = strongly. Skip the ones you don't feel sure about. Aggregated only — no comments stored at the row level.

What would improve this park?

Generated from the weakest measured dimensions — a starting point, not a prescription.

  • Activate the edges: encourage cafés, retail or community uses on the streets that face the park; replace blank or parking-lot edges where possible.
  • Diversify what people can do in the park — playground, washroom, water, shade, performance, sport, garden — even small additions raise this score.
  • Increase canopy and reduce paved area. Shade and water features extend usable hours and seasons.
  • Encourage mid-rise, windowed frontages around the park so residents have direct sightlines onto it.
  • Mitigate border vacuums (highways, rail, parking) with active programming on the still-permeable edges and treat the hostile edge as a design challenge.
