Episode 422: On St. Patrick's Day, 1960, five Italian immigrant construction workers — Pasquale Allegrezza, Giovanni Carriglio, Giovanni Fusillo, and brothers Alessandro and Guido Mantella — died beneath the Don River in Toronto's Hogg's Hollow neighbourhood. They were trapped in a tunnel less than two metres wide with no fire extinguishers, no hard hats, and no way out. The fire was preventable. The violations were known. A foreman had been fired for raising them. No one was ever charged. This is the story of five men whose names were nearly forgotten — and the laws that exist today because they died.
