This development has been concentrated in the downtown core, especially in the former industrial areas just outside the central business district. The largest such project is CityPlace, a cluster of condo towers on former railway lands by the lake shore. This $2 billion project will eventually consist of 20 different towers housing some 12,000 people. Transit-oriented developments are also common in Toronto, such as at North York Centre and Sheppard East along the namesake subway line and Sheppard West along the subway line's future westward extension.
