Key findings

1. The Toronto Park Catalogue is bimodal

Of 3,273 parks, only 220 (7%) score above 50 on both urban integration and natural comfort. The Toronto Park Catalogue divides cleanly into urban social parks (good for daily life, exposed to heat) and ecological retreats (cooled and shaded, hard to reach). Genuine balanced hybrids are rare.

Each dot is one Toronto park. The split is structural, not accidental. See the ravine paradox essay.

2. Parkettes outperform expectations

505 pocket parks (under 1 ha) average 34.0 on the overall score versus the citywide mean of 34.6. Tightly framed by mid-rise rowhouses, well-served by transit, with multiple access points along their tiny perimeters, parkettes capture the urban-form conditions Jacobs argued for almost by accident. The biggest gainers in this build are all small downtown parkettes. Read the essay →

3. Ravines excel ecologically but disconnect socially

1,115 parks (34%) land in the high-natural / low-urban quadrant: the largest quadrant outside “underperforming”. Ravine and conservation parks score above 90 on natural comfort while their connectivity stays below 15. The same conditions that make the ravine valuable as ecosystem also make it inaccessible for everyday urban use.

4. Waterfront parks are highly connected but weakly enclosed

Toronto’s lakefront strip is exceptionally well-served by transit and pedestrian infrastructure, and the waterfront parks score correspondingly well on connectivity. They score poorly on enclosure: there is almost no built edge between Lake Shore Boulevard and the water, so the parks have little frame and little “eyes on the park”. The result is parks that reach a lot of people without offering much social grain. See the list →

5. Mid-rise neighbourhoods produce the strongest balanced parks

The parks with the highest enclosure scores in the city are nearly all surrounded by 3 to 7 storey buildings, the form most of pre-war Toronto was built in. New builds at this scale have largely stopped; tower-and-podium has replaced them. The data picks up the difference clearly.

6. Tower-in-the-park landscapes consistently underperform

The auto-detected tower-shadow pattern surfaces parks where the enclosure score is technically high but driven by tower walls rather than mid-rise frontage. These parks pay the comfort and shadow costs without getting the ground-floor activity. The model says the urban form here doesn’t deliver the conditions Jacobs described, and that has stayed remarkably consistent across the Toronto Park Catalogue.
