Doors Open Toronto ended just over a week ago, but images from the yearly event just keep on rolling in to our Forum and Flickr Pool. Today's Photo of the Day, submitted by Flickr member Frank Lemire, takes us inside of the R.C. Harris Water Treatment Plant at Queen and Victoria Park. Opened in 1941, this beautiful piece of Art Deco infrastructure has had its exterior featured in many films and television shows, but the inside of the facility is certainly one of the city's most impressive interior spaces.
