Associate Lisa Dietrich talks with Torontales’ journalist Sarah-Joyce Battersby about Toronto’s mysterious PATH system. The PATH, a puzzling, peculiar, yet widely used underground walkway system in Toronto’s financial district, has been a central focus of Dietrich’s research over the past 7 years, serving as the topic of her architecture thesis at HafenCity University in Hamburg, Germany, and more recently as the theme of her guided walking tour with Jane’s Walk.
