I visited Casa Loma with a friend in October and had a beautiful few hours exploring this interesting space. The audio tour really is worth it and they go to great lengths to expose everyone to the depths of history and detail there. Working in the furniture trade it is of particular value to those interested in heritage and history and really adds texture to a visit to Toronto. My small criticism is that you have to go back to the bowels of the castle to return your audio set but otherwise very nice stop.
