In this episode of The Backroads Bill Podcast, amateur historian and author Paul Ozorak joins the conversation to explore the Cold War bunkers, fallout reporting posts, radar stations, and abandoned military installations that still remain across Northern Ontario and beyond.
The discussion begins with a bunker recently exposed at Samuel de Champlain Provincial Park after the June 2025 storm brought down surrounding trees. From there, Paul explains why Canada built so much military infrastructure during the Cold War, how fallout reporting posts were used, and what made places like the Diefenbunker and North Bay’s underground complex so important.
