111 Waterloo St., Suite # 606
Located on Waterloo St., right across from "Old Victoria Hospital". Hill and South Streets are the adjacent side streets. It's just inside (east) of Wellington Rd and below (south of) Horton St..
Free parking in the building lot. Yes, there is a kiosk at the entrance, it is unmanned, ignore it and come on in.
I've attached a map, and pictures of the building. Many of you will recognize it.
