A significant transformation is on the horizon for a vast parking lot located at 4105 Kingston Rd., near Guildwood GO station in Scarborough, Ontario. The provincial government has tabled a Transit-Oriented Community (TOC) project, which aims to replace the surface parking lot with a complex of six towers as tall as 60 storeys. This project is part of a larger initiative to promote transit use and infuse density into areas surrounding transit stations.
The Proposed Transit-Oriented Community (TOC) Project
The new TOC project is a progressive step towards utilizing underutilized land and promoting transit use. The proposal plans to replace the commuter lot serving the regional rail station with a complex of six towers, introducing 2,534 new residential units to the site, currently underbuilt.
Design and Plan
Following the TOC model of integrating density with transit, the proposed complex’s tallest towers would be placed closest to the GO station. The tallest tower would measure just shy of 193 metres. Although the heights are significant in the local context, the plan would rank as just the 37th-tallest building in Toronto if completed today.
Green Spaces and Parking Facilities
The project also aims to offset the concrete density by incorporating a network of parkland and open spaces. These will include both public and privately-owned public spaces, combining for almost 5,600 square metres. While the large surface parking lot would be lost, the TOC plans to incorporate new commuter parking, as well as pick-up/drop-off areas serving the station’s significant share of riders relying on cars to get to and from Guildwood GO. The complex’s underground parking garage would contain 709 replacement parking spaces for Metrolinx, along with an additional 760 commuter spaces at-grade.
Future TOC Projects
This is not the only TOC project in the pipeline. Recently, Infrastructure Ontario dropped plans for an even larger seven-tower complex set to replace surface parking over at Clarkson GO station. Both these new TOC proposals would replace commuter lots and feature strikingly similar designs from Zeidler Architecture.
