So-called "heritage preservation" must address not just exteriors but also interiors. Sure, Toronto has lots of beautiful old bank buildings (Americans joke that Toronto had a bank on every corner, whereas their cities had a tavern on every corner), but much of the beauty was on the inside. Even if the buildings still stand, many of these marble, granite and wood interiors were replaced with formica counters and cubicle offices over the past decades -- a serious loss and an insult to interior design. The building at 49 Yonge has not only a beautiful exterior but also a grand, airy, spacious interior from its former life as a banking hall, beautifully maintained and respected by the current occupant, The Irish Embassy (an excellent establishment, if you haven't been there). It deserves to be preserved in a way we can all continue to experience and enjoy it. If the interior can't be preserved in a way that is respectful, functional and accessible, then the heritage objective is moot.
