Toronto’s Most Dangerous Relic | The Hearn Power Plant

Once a cornerstone of Ontario’s power grid, the Hearn Generating Station loomed over Toronto’s waterfront, silently shaping the city’s growth. At its peak, it supplied 10% of the province’s electricity—fueling industry, innovation, and modern life. But behind its brick facade was a dangerous maze of turbines, steam, and human effort. This was no ordinary power plant—it was a colossal machine that ran 24/7, with lives on the line.

In this episode, we trace the rise, operation, and dramatic decline of the Hearn Station. From its ambitious beginnings on reclaimed marshland to its role in powering a growing metropolis, we uncover the political battles, technological triumphs, and personal stories that defined its legacy. Today, it’s abandoned—but not forgotten.
