Well, I'm a great believer that it's because of the character in the stories that it tells. You can look at some of these beautiful buildings we lost, and you almost want to cry over what we have lost over the past, especially in Toronto where there certainly was in the 1950s and 1960s a real priority placed. You have lost the story of what the city was about. You actually lose particular buildings. The beautiful residence that was once the home of the Lieutenant Governor of Ontario—gone. It was a place that, if it was maintained today, would be far more attractive for people to visit than, say, Casa Loma or something.
Also, some people point to the environmental benefits of the reuse of buildings, instead of dumping the materials and so on and demolition, but I really think it's the character building and the history storytelling that really make the biggest difference.
