Transition Zones

Height, density and use across urban neighbourhoods

Blair Scorgie

A framework for adding homes and suitable local uses between main streets, transit and established neighbourhoods, with a more gradual change in height and density.

Transition Zones considers how planning can address change across adjoining properties and blocks. The report brings together Toronto’s policy history, research and local examples to identify where the approach could apply and how it could work.

Selection criteria connect the framework to proposed housing forms, local uses and development standards. The report also sets out policy, zoning and implementation steps, supported by maps, diagrams and illustrative concepts. The framework was developed by Blair Scorgie in collaboration with Sean Hertel.
