Scores are not bell-curved. Percentiles and expected scores provide context without changing the underlying model.
Explain this score
Where did the 24 come from? Each weighted contribution against a neutral 50 baseline. Green = pushed up; red = pulled down.
Sum of contributions = the headline score. A negative bar means that dimension dragged the park below the city-wide neutral baseline.
Why this park works
What limits this park
Most distinctive characteristic
Jacobs reading
Tradeoffs
- The park is enclosed by buildings (71) but the surrounding streets are quiet (edge activation 0) — frame without animation.
- 6 nearby towers cast wind and shadow without contributing canopy — passive surveillance is plentiful but human-scale comfort is not.
Performance in context
- Strong underperformer relative to its cohort — raw 24 vs an expected 39 (gap -15).
Typology classification
Classified as Civic Square: name flags as civic square + 33 buildings frame the edge. Secondary read: Neighbourhood Park (1.1 ha, framed by 26 mid-rise vs 6 towers).
Edge Activation
Within 100 m of the park edge: 43 active uses (community, cafe, transit_stop, retail, restaurant) and 13 dead/hostile uses (highway, parking_lot). Active edges keep "eyes on the park" through the day; parking lots, blank institutional walls, rail and highway frontages drain street life.

Connectivity
Connectivity blends paths, intersections, transit, entrances, and edge density. This park has 0 mapped paths/walkways and 12 sidewalk segments within 50 m; 2 street intersections within 100 m; 12 transit stops within a 400 m walk; 2 estimated access points across ~432 m of perimeter. moderate edge density — small superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
No amenities recorded — score is 0 until inventory is loaded.

Natural Comfort
Natural-comfort components for this park: ~15.4% effective canopy (0.0% from contiguous tree polygons + scattered tree density); nearest waterbody ~1085 m; 24 city-mapped trees inside the polygon (21.9/ha). Reading: exposed. Source coverage: waterbodies, street_trees. Impervious surface is approximated (Toronto's authoritative layer ships only as a raster GeoTIFF).

Enclosure / Eyes on Park
33 buildings within 25 m of the park edge (26 mid-rise, 1 low-rise, 6 tower); avg edge height 35.6 m (~12 floors); 7.6 buildings per 100 m of 432 m perimeter — strong frontage density; edges lean tall but still framed; 6 towers ≥ 40 m within 25 m of the edge. "Eyes on the park" come strongest from the 26 mid-rise edge buildings.

Border Vacuum Risk
Border-vacuum factors within 50 m of the park: Yonge Street, Yonge Street, Yonge Street, Yonge Street, parking_lot, parking_lot, parking_lot. 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.

Does this score feel accurate?
Your read of Mel Lastman Squarematters. 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.
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.
- Add or open more entrances and improve sidewalk continuity around the park. More permeability means more spontaneous use.
- 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.
- Mitigate border vacuums (highways, rail, parking) with active programming on the still-permeable edges and treat the hostile edge as a design challenge.
