The Commission has engaged independent researchers and report writers to prepare Commissioned Reports to explore issues in its mandate.

What are Commissioned Reports?

An important part of the Mass Casualty Commission’s work is to explore the causes, context and circumstances giving rise to the April 2020 mass casualty in Nova Scotia. To support this work, the Commission has commissioned two kinds of reports: Technical Reports and Expert Reports.

  • Technical Reports provide factual information about matters such as the structure of policing in Nova Scotia. These reports will support the Commission’s work by providing an objective and factual account of some of the key government and policy structures that are relevant to its mandate. In selecting report writers for Technical Reports, the Commission focused on the independence and relevant experience of the report writers.
  • Expert Reports gather and analyze public policy, academic research and lessons learned from previous mass casualties. These reports will help further the Commission’s mandate by analyzing matters such as policing, emergency services responses, communications with the public and how best to support individuals and communities following a mass casualty. In selecting writers for the reports, the Commission focused on the Canadian legal criteria for expert witnesses including independence, the suitability and reliability of research methods, depth of knowledge and the necessity of a report written on the matter.

Commissioned Reports will be shared with Participants first to allow them to prepare for the Commission’s public proceedings. The reports will then be made public as part of the Commission’s proceedings.

Steps to create Commissioned Reports

Commission Expert Reports
  • 1. Engage report writers

    Report writers are engaged to write independent reports about issues in the Commission’s mandate. Topics include:

    • Police resources & decision-making
    • Public communications
    • Understanding mass casualties
    • Supporting communities after a mass casualty
    • Gender-based and intimate partner violence
    • Access to firearms
  • 2. Share with Participants

    Commissioned Reports are shared with Participants so they can prepare for public proceedings and make submissions.

  • 3. Share with public

    Commissioned Reports are shared publicly on the Commission’s website and discussed during public proceedings. Report authors and other experts may be invited to take part in public proceedings such as roundtables.

  • 4. Inform findings and recommendations

    Commissioned Reports help to inform the Commissioners’ findings and recommendations.

Phase 2 Commissioned Reports

A list of the Commissioned Reports for the Commission’s Phase 2 work (exploring the broader context and issues) is below. Additional Commissioned Reports may be prepared to respond to questions raised by Participants and to assist the Commissioners as they draft recommendations to help make communities safer.

  • Supporting Survivors and Communities after Mass Shootings

    This report addresses the needs of survivors and communities in the wake of mass casualty events. The report draws from the author’s empirical research with survivors and communities to provide recommendations about how survivors’ and communities’ needs should be understood, how these needs may change over time, and how they may change with the context of a given event and the community in which it occurs. The report also explains how needs for support may be distributed within a community beyond the circle of those most directly affected by the events.

  • Rigorous Forensic Psychological Assessment Practices

    This report defines the field of forensic psychological assessment and draws upon decades of research and scholarship from and about fundamental basic science and forensic science, as well as clinical and forensic psychology, to lay out eight best practices that may be used by law enforcement agencies and courts to evaluate the rigor and value of a psychological evaluation. We review the scientific and evidence basis for techniques used by psychological evaluators, and describe best practices for and limitations of psychological assessments in a manner that is generalizable to various kinds of psychological assessments, including psychological autopsies and behavioral profiling as used by law enforcement agencies. Although both psychological autopsies and behavioural profiling depart somewhat from typical forensic psychological practice, both can be considered forms of forensic psychological assessment, and as such we opine that the norms, values, and expectations for best practice in forensic psychological assessment should apply to these techniques. This report will aid the Commission in assessing the extent to which the "Psychological Autopsy" and "Behavioural Profiles" produced with respect to the perpetrator of the April 2020 mass casualty that took place in Nova Scotia reflects evidence-based techniques and best practices in forensic psychology.

  • Culture in police organizations: Definitions, research and challenges

    Dr. Campeau draws on policing studies literature but also on the sociology of culture and organizational culture to define and understand culture, and specifically police culture. Her core argument is that culture is a resource or repertoire of tools that police can draw on in a given situation, rather than being a set list of beliefs or values that fully determine how a given police officer will act in a given moment. She also explores the differences between the cultural resources drawn upon front line members and those used by police officers who serve in management roles. Finally, Dr. Campeau draws on her own ethnographic research with police officers in Ontario to describe how this understanding of police culture as a resource aids interpretation and understanding of police work.

  • Exercising Judgment: Understanding Police Discretion in Canada

    This report provides a critical examination of the scholarly literature on the nature of police discretion, focusing on how the working culture and organization of law enforcement agencies fundamentally structures the exercise of police discretion and associated powers, such as the powers of arrest, detention, and use of force. In particular, this report highlights some of the key barriers to making police discretion more transparent, information sharing more routine, and oversight more effective. The report attends to comparative examples from non-Canadian jurisdictions to identify some best practices and promising approaches to ensuring that police services are subject to meaningful legal oversight and accountable to the diverse communities they serve.

  • The History of Gun Control in Canada

    This report provides a legal history of firearms regulation in Canada. The report explains the strategies that have been used to address the dangers associated with firearms (in particular semi-automatic long guns) and address the debates that have played out within Canadian public policy about these strategies. This report addresses the enforcement of firearms regulation and the smuggling and illegal trafficking of firearms and associated paraphernalia. Where possible, the author identifies the strength and shortcomings of past legislative approaches and of plausible alternative approaches. Where possible, the report identifies what (kinds of) weapons have been implicated in mass casualty events in Canada, with reference to specific examples and the legislative or policy response, if any, to these events.

  • The Health and Safety of Survival Sex Workers in Halifax and Truro, Nova Scotia

    This report investigates the health and safety of survival sex workers in the Halifax Regional Municipality (HRM) and in rural areas of the province by examining 1) how sex workers experience community safety in Nova Scotia; 2) how they ensure their own safety; and 3) their relations with community agencies such as the police, the health care system, and other community service providers. Our investigation also looks at barriers to reporting victimization, including distrust of the provincial health care system and distrust of the police. Throughout, this report centres and addresses the experiences of sex workers who are marginalized due to Indigeneity, racialization, because they are 2SLGBTQ+ (or engage in sexual activity with 2SLGBTQ+), or for other reasons.
