This is a list of prisons and other secure correctional facilities in Canada, not including local jails. In Canada, all offenders who receive a sentence of 24 months or greater must serve their sentence in a federal correctional facility administered by the Correctional Service of Canada (CSC). Any offender who receives a sentence less than 24 months, or who is incarcerated while awaiting trial or sentencing, must serve their sentence in a provincial/territorial correctional facility. Members of the Canadian Armed Forces who are sentenced under military law serve their sentences at detention barracks designated by the Department of National Defence. For inmates with serious mental health conditions, CSC has 5 regional treatment centres. In addition, CSC also provides healing lodges specifically for Indigenous offenders, designed with the intention "to address factors that led to their incarceration and prepare them for reintegration into society." CSC currently funds and/or operates 10 healing lodges across Canada, while others are operated by local Indigenous communities or partner organizations.
