Both the child protection and criminal justice systems have the common goals of preventing and protecting children from harm as well as an interest in sharing information as effectively as possible in order to achieve these goals. Before recommending possible improvements, the report discusses what information about risks to children, and from what sources, is collected by or may come into the possession of the two systems; the current Canadian laws and policies that govern information-sharing in the two systems; the problems, impediments, or barriers to effective sharing of information; and the actions that have been implemented or are proposed in Federal, provincial, and territorial jurisdictions to address identified or perceived deficiencies. Various review bodies and coroners' inquests have identified deficiencies in information-sharing policies and practices relating to the handling of cases of abuse and neglect. These include misunderstandings about roles, functions, and mandates; inadequate training; problems in the collection and accessibility of information; case management problems; failure to plan based on information available; and faulty assessments of risk. Recommendations are offered for addressing identified deficiencies in the sharing and use of information shared between the two systems.
