Canadian photographer Maureen O'Connor's work is always one of the highlights for me of the Toronto Outdoor Art Fair. If I don't find her booth on my own meanderings, I make a point of seeking it out. I can't leave until I've seen her new photos.
All of the animals in her pictures are live — there's no taxidermy and no posing. The creatures, which to my understanding live in rehabilitation sanctuaries, are brought to the abandoned buildings and allowed to explore.
You can see all O'Connor's work at maureenfaithoconnor.com. The above are all from the Threshold series, but the Inclusion, Departures, and Cuban series are also excellent.
