My wife and I live in Toronto and have watched the Listener from the beginning. We get a chuckle out of the fact that St. Luke's emergencyentranceis really the emergency entrance to Sick Kids on University. But, try as we might, we can't isolate what building they use to shoot the exterior of the IIB Building. We see it many times in every episode. There are street car tracks running out in front of it. We'd really be curious to know what this building is and where it is. Any ideas?
