Ooh, torches and pitchforks!
Yes, that's exactly what I'm proposing. Let the grubby hordes of Toronto trample the beautiful gardens of Osgoode like so many cattle. Let them bring their crumpled-up Tim Hortons cups and sleeping bags and stink. Let them use it as a shortcut to hither and yon. Let them pound it into mud.
I think what I like best about this idea is the howling it provokes. The beauty of the gardens would certainly be sacrificed, but if I was playing SimCity with the place, it's a sacrifice I would make. To my mind, the space is wasted because the fence creates a space that's semi-private, gives a sense of equisite exclusivity, and can't easily be traversed as a shortcut from point A to point B - which really is the only reason people traverse anything. In other words, it's exactly what Osgoode wants it to be. Since it's not broken, I say fix it.
Also, have I told you how much I love the Ryerson business school?
