This report comes from a Corus employee at their new Diamond Schmitt-designed headquarters, namely Corus Quay, on Dockside Drive in Toronto's East Bayfront brownfield redevelopment area:

"There are birds trapped in this building from when they started building it. Everyone is too nice to kill them so they just fly around and try to eat my salad. Plus the slide just opened and so people are lined up beside my desk waiting to go down it. Of course the top of the slide is NEXT TO MY DESK." 

So, no photos of the birds, but here's Corus' slide:

I'd be lining up too.
