In today's Photo of the Day, which was submitted to the UrbanToronto Flickr Pool by edk7, we are shown the underside of the iconic Slaight-Gattuso stairway at the Art Gallery of Ontario (AGO). Part of Frank Gehry-led 2008 renovation of the institution, this wooden helix staircase is the central design element within the gallery's Walker Court.
