For 30 years I’ve been conducting comparative studies in downtown Toronto’s commercial and residential neighbourhoods, documenting the ways in which they shift and change over time. The ever-growing archive of images documents the survival, transformation and, sometimes, demise, of various relatively ordinary structures as they continually change, in function and facade. Toronto is full of such structures, which constantly undergo alterations, in a pragmatic adaptation to changes in building materials, in design attitudes, and, indeed, in social values, having layer upon layer of new, often discordant details added to their surfaces.
