Toronto policy and missing middle housing: case studies for policy reform
Bibliographic record
Abstract
This paper examines how the Toronto Official Plan and zoning bylaw have limit the market from effectively responding to housing demand. These documents protect Toronto’s ‘stable’ neighbourhoods from increased density and restrict development of affordable missing middle housing forms which could provide ground-related housing in desired areas. Policy which limits housing options in existing communities has contributed to negative social, economic, and environmental outcomes within cities. Recognizing the negative impacts of exclusionary zoning, jurisdictions across North America are reforming policy and zoning bylaws to permit multi-unit housing in areas zoned for single-detached housing. This paper reviews reform processes in several jurisdictions and recommends that Toronto reform its Official Plan and zoning bylaw to permit increased housing options across the city, conduct outreach to change opinions on increased density, incentivize production of missing middle housing, and use land value capture tools to limit increases in land values brought about by rezoning. KEYWORDS missing middle housing, yellowbelt, stable neighbourhoods, Toronto, zoning

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
