Harris Plant Building - a Palace of purification
This plant was build in 1932-1941, in is in Art Deco style. There are 5 buildings, all recently renovated (2010-2011).
The plant was under renovation when I visited, so I photographed the only building, which is finished.
There is another Toronto photographer (Faryndale) on Panoramio.
He has some fantastic photos of this plant. He does not communicate with other users, but he makes an beautiful record of Toronto streets.
