A railway in Toronto's downtown core could soon see a massive new community of condos, office towers, and green spaces sitting on top of it.

CRAFT Development Corporationhas released updated renderings and a new concept video for theORCA Project.

First pitched to the city in 2017, the ORCA Project proposes a 16-acre development that will sit elevated above the active rail corridor located just south of Front Street.

The railway tracks, which make up the Union Station Rail Corridor, have cut across this stretch of Toronto since the 1850s.

The development would transform 16 acres of land into space for towers, retail, office spaces, and parkland. Photo via ORCA Project.

In an attempt to utilize the precious airspace above the tracks, ORCA proposes building a deck overtop that stretches from Blue Jays Way to Bathurst Street.

That platform will allow a mixed-use development made up of residential towers ranging in height, rooftop terraces, plazas, walkways and a 36-storey office building.

CRAFT has acquired the air rights for the site from the Canadian National Railway to bring that vision to life.

Intended to be the project's centrepiece is a new 12-acre park proposed as theRail Deck Park, which would include public art, lawns, and trees that could connect to the existing Northern Linear Park in CityPlace.
