Information collected covered demographic variables, criminal history, performance while on release, the nature of the violation leading to suspension, action and decisions taken, and time periods in the suspension/revocation process. Data were analyzed to determine the reasons for suspension, the concordance between decisions by the Correctional Service of Canada (CSC) and the National Parole Board (NPB), outcomes according to the nature of the violation, case factors associated with decision outcomes, and time delays. In addition to file reviews, interviews were conducted with 32 NPB members and 161 CSC parole staff across Canada. This report describes the suspension/revocation process, reviews the research literature on parole and parole revocation, and summarizes developments in law and regulations that have shaped the process in the past 10 years. Recommendations are under the following headings: CSC documentation, time delay, criteria for suspensions and revocations, and criteria for re-credit of remission.
