Scene was shot Built in 1941 atop a former amusement park, the R. C. Harris plant currently provides almost half of Toronto's drinking water. The building was designed in the art-deco style and is known colloquially as the Palace of Purification for its grand architecture both inside and out. The plant was named after Rowland Caldwell Harris, who was Toronto's Commissioner of Works at the time of construction.
