In case you missed it, the Commission held a brief virtual proceeding today to mark additional documents as exhibits.

Although public proceedings concluded on September 23, we reconvened briefly today to mark additional documents as exhibits.

The Commission requires any outstanding documents that should be part of the public record and that may inform our final report to be marked as exhibits. Participants, counsel, and Commission teams worked to bring forward groupings of final documents including supporting material for public proceedings that were not previously marked; transcripts of recent interviews; correspondence between the Commission and Participants for the public record; and documents produced to the Commission after the completion of public proceedings.

We have been under time constraints throughout this inquiry and with this complex mandate, but we are committed to completing the final report within our timeframe, ensuring it is both rigorous and comprehensive.

These documents exhibited today were shared with Participants in advance, and we are providing time for any Participants who want to make submissions based on any of the additional documents. We know this is not optimal, but we continue to believe Participant input is important while we also strive to work within our timeframe.

We are appreciative of the effort that Participants and counsel have put into reviewing material. This appreciation also extends to the public and the media. Our hope is that you will review the documents of interest to you in the coming weeks and months.

To assist you, all transcripts from public proceedings are available on the Commission’s website, where you will also find proceedings webcasts, the Foundational Documents and source materials, investigations supplementary reports, commissioned reports and much more information about both what happened on April 18 and 19, 2020, and how and why it happened.

Addenda and errata to Foundational Documents arising from our work have been added to the website, along with related source materials. Addenda include additional material, and errata include the correction of any errors.

Thank You to Families and Community Stakeholders

We reiterate our thanks to the many people who met with us during the final few weeks of public proceedings, including those who took part in community stakeholder sessions, and especially to the family members who joined us in small group sessions to speak again about their experiences of the mass casualty and suggested recommendations. These conversations were challenging, took a lot of courage, and will make a strong contribution to our ongoing work. Thank you all.

As we have said, we are focused on preparing the final report, and we remain committed to making sure recommendations are clear and implementable. Public safety is a shared responsibility and opportunity. It will take many people in many settings and roles to help make our communities safer.

As always, pathways to mental health, wellness and other supports are available if you or a loved one need them.
