I went to a couple of places in City Hall that I have never been to before - up on the Podium Green Roof terrace, into the Mayor's office, the Council Chambers and to the top of the building on the observation deck, during the 2010 Toronto Doors Open event.
The green roof terrace opens space that was previously closed to the public right beside the council chambers. Green stuff came alive with two alien green things wandering the terrace - they might have been undercover security in advance of the G20.
Mayor David Miller joined others for the official opening of the green roof that looks down on Nathan Phillips Square. He has a nice office in City Hall with a decorating motif in his office suite.
There were also a few kids dressed on stilts and in costumes like a butterfly and a swan.
On top of City Hall the observation deck is on the 27th floor and provides a nice view of downtown Toronto. Also Below are two of the friendly Doors Open volunteers helping to keep things running smoothly during the event.
