Took this set back in 2011 (about a year before those photos in the article):

Here's a birds-eye view on Bing maps (Google Maps have since been updated).
At one point they had another train car, an H6 I believe, but it was removed much quicker. It was much closer to the building (though it was off the tracks). Almost got spotted both by two TTC drivers - one standing on the roof of the building having a smoke and one pulling into the yard in one of the new Toronto Rockets, and by some firefighters who were doing drills (or something) next door at the airport.
I'd heard that they were used by Toronto Police to train on, but I'm not sure how accurate that is. When I first visited it was clear nobody had been there for a while, but there was also a step stool inside the door so that people could easily get in/out.
