Unauthorized Personnel Allowed is a photographic series documenting the Ontario Line subway's construction, rapidly reshaping the Don River's Lower and Western branches, the neighbourhoods of Thorncliffe Park, Flemingdon Park, and around the now-shuttered Ontario Science Centre. Through repeatedly walking the landscape and responding to the continual changes, Toward uses the camera as a mnemonic device to process and archive the active construction and redevelopment of the land. Unauthorized Personnel Allowed questions how the surrounding landscape is documented while in flux and how the photographic process has historically been used to obfuscate these changes brought on by human dominance over nature.
