On Wednesday, April 27, members of the Commission team facilitated the first of several roundtable discussions to come. This was an opportunity for us to hear directly from people with knowledge and experience on the subjects of police paraphernalia and police impersonation. Creating the space and time for this discussion allowed us to better understand the issues related to how and why various aspects of the mass casualty could have happened (for example, how someone can access or create police paraphernalia). The learnings from the roundtable, like perspectives on collecting police paraphernalia or the significance it has during certain events, will inform the recommendations included in our final report to help prevent and respond to similar incidents in the future.

Members of the roundtable reflected a diverse range of perspectives including a former police chief, a social justice lawyer, a professor of criminology, a collector of police paraphernalia, and a representative from RCMP Veterans Nova Scotia who is also a Participant.

To learn more about the roundtable topics and the members, visit the website’s new roundtables webpage. For documents related to roundtables, please visit the Research and Commissioned Reports webpage.

Commissioned Reports

This week the Commission released the first seven Commissioned Reports. These reports are prepared by independent writers and focus on public policy, academic research and lessons learned from previous mass casualties. Commissioned Reports are necessary to explore the causes, contexts and circumstances that may have contributed to the mass casualty. This work will help us better understand the related issues outlined in the mandate including access to firearms, gender-based and intimate partner violence and police policies.

The reports shared this week included:

More than 20 reports will be shared over the course of our work. A full list of reports is available on the website.

Interim Report

The interim report is an important checkpoint that shares details on the work we have been doing thus far on behalf of Canadians to meet the requirements of the mandate. The Commission has submitted the interim report to the governments of Canada and Nova Scotia in advance of the due date this Sunday, May 1, 2022, as outlined in the Orders in Council. We plan to share the report on the Commission website on Monday, May 2.

Our work is still underway, which means this report does not include recommendations or findings. Over the spring and summer, proceedings will continue to provide clarity about what happened, and how and why it happened. At the end of the mandate, the Commission will submit a final report to the governments of Canada and Nova Scotia containing findings, and recommendations to help prevent and respond to similar events in the future.

Commission Source Material

The source materials related to the Police Paraphernalia and Replica RCMP Cruiser Foundational Documents that were tabled Monday, April 25 are now available on the website. Source materials related to Foundational Documents will continue to be added to the website two business days after they have been marked as evidence during proceedings. In some rare instances, there may be further delay for individual documents that are being reviewed or summarized.

Source materials that do not relate to a specific Foundational Document can now be found on the Foundational Document page when filtering source material by “Additional Exhibits”.

In rare instances, a source material may need to be removed from the website after it has been posted. This has occurred very infrequently as a result of claims of privilege or private information, such as information that could identify a minor, or medical information. When this happens, the document is removed out of an abundance of caution and re-posted once appropriately reviewed and updated if required. For more information, visit our website.

Venue Change for Proceedings

The venues for public proceedings change periodically so please use the registration portal or website calendar to confirm locations on the date you wish to attend. For the week of May 2, public proceedings will be held at the Dartmouth Hilton Hotel. Members of the public can register to attend proceedings in person on the website.

As always, you can watch the webcasts or listen to live audio from the proceedings by calling 1-877-385-4099 (toll free) and entering code 1742076 followed by the # sign. Recordings of the webcasts along with transcripts are available, so that you may engage in this work at a time that works best for you.

Thanks to your continuing engagement, we are making progress in our work, sharing answers with the public about what happened, and exploring how and why it happened. Please remember, supports are available if you or someone you know needs help, both on-site at the proceedings and through the website.
