I am posting the original description from the site because I really like the idea of it and I'd like to keep it around.
The Toronto Psychogeography Society is a loose collection of relentless flâneurs, explorers and walkers. The word psychogeography was coined by the Situationist Guy Debord. It describes the specific effects of the geographical environment on the emotions and behaviour of individuals. The streets of Toronto become a playground, and each route presents a new urban adventure as participants step out of their daily routine and explore the city's overlooked corners to imagine the dynamics of a better future urban environment.
