Underlying infrastructures organize and manage complex systems of movement and exchange and can set the stage for future development. However, when developed as a mechanism primarily devoted to solving transportation engineering issues, they can contribute to the creation of inhospitable places in a city. This thesis project primarily explores how transit infrastructure, specifically the development of the new Ontario Transit Line in Toronto can act as a public agency to reinvigorate the transit desert community of Thorncliffe Park. Specifically, the project examines infrastructure under the following lens: as a community builder and public amenity; as a spatial definer and connector; and the train line as an animator of the public realm. This thesis argues that infrastructure, conceived as architecture, through a lens of agency can still provide efficient access and diverse modes of transportation to other parts of the city, while creating a connected, integrated, and engaging community fabric.
