5 Most Evil Inmates of Millhaven | Inside Canada's Most Infamous Prison | The Prison Files

Deep in the bleak, wind-swept landscape of eastern Ontario, sitting heavily on the edge of Lake Ontario, looms a massive concrete fortress that has struck fear into the hearts of criminals for over half a century. This is Millhaven Institution, universally known to generations of guards and inmates simply as Canada’s ultimate destination for the uncontainable. Opened in 1971 amidst a chaotic, emergency transfer of prisoners during a deadly riot at nearby Kingston Penitentiary, this maximum-security fortress serves one singular, grim purpose: to hold the most calculated, volatile, and notorious offenders the rest of the federal correctional system cannot handle. Behind these heavily armored, high-tech perimeter walls sits a stark world of intense surveillance, specialized control units, and the Regional Treatment Centre. In this chilling episode of The Prison Files, we unmask five of the most calculated, notorious, and disturbing inmates to ever enter this living hell—men whose crimes were so severe that they earned a permanent spot inside Canada's ultimate maximum-security cage. From the terrifying, cold-blooded predatory path of schoolgirl killer Paul Bernardo and the deceptive garden plot burials of Toronto serial killer Bruce McArthur, to the dark, calculated alliances of thrill-killers Dellen Millard and Mark Smich, and the harrowing family betrayal of the Kingston Mills honor killings by Hamed Shafia, we break down their harrowing profiles, their psychological motives, and the brutal reality of serving a life sentence behind Canadian glass. Watch until the end to understand the extreme layout, the history of high-profile lockups, and the specialized security measures the facility uses to ensure that once an inmate enters the razor wire of Millhaven, they are separated from civil society forever. Stay sharp, stay vigilant.
