An Act to amend the Corrections and Conditional Release Act

Bill S-205 (45-1), known as Tona's Law, is a Senate Private Member's Bill from Senator Kim Pate (Independent Senators Group) to curb solitary confinement in federal prisons. It would amend the Corrections and Conditional Release Act to cap stays in isolation, which Correctional Service Canada calls structured intervention units, at 48 hours unless a Superior Court orders otherwise, require that anyone with a serious mental-health condition be moved to a hospital rather than held in isolation, and add independent oversight and legal remedies for prisoners whose rights are breached. It is named after Tona Mills, an Indigenous woman who developed isolation-induced schizophrenia after more than a decade in segregation. Public Safety Canada reported a 36 percent rise in isolation stays of 61 days or more between 2021 and 2024. Pate has pressed the issue since the 2018 reforms; an earlier version of the bill died when the 2025 election was called, and this version is before a Senate committee.
