Northern Toll: The impact of the drug toxicity crisis in Northern Ontario corrections examines how an increasingly lethal drug supply, strained services and disruptions in continuity of care can increase the risk of fatal drug poisoning for Northern Ontario’s correctional population. The report highlights how the transition back to the community is a particularly dangerous time. Without stable housing, timely access to treatment, or coordinated in-reach supports, the danger can quickly escalate. Drawing on discussions in Thunder Bay, Sault Ste. Marie, and Sudbury, the report brings together local perspectives on the crisis and identifies opportunities for a health-focused response to reduce preventable deaths.
