On the Brink is a collaborative project examining the everyday and what this means for urban areas facing gentrification. Mortensen examines Walworth, one of the last areas of central London to be cleaned and priced up. These images are juxtaposed with Celeste’s images of Toronto’s Eglinton West. Thousands of kilometres apart, both neighbourhoods are subjected to demolition and reconstruction. These photographs raise the question of how these spaces will look, feel, and function in the coming years.
