This talk explores how Canadian urban waterfronts can learn from global practices of tactical urbanism based on forms of the public bath. It builds upon a line of thought initiated in my publication The Architecture of Bathing: Body, Landscape, Art (MIT, 2020). It will look at projects by community members, artists and architects, and trace their origins and supports. Examining a series of initiatives from around the world, we will discover networks of tactical urbanisms which are both wild and sustainable while engaging deeply in regional communities, politics and ecologies.
