This update includes information about documents that have been added to the Commission website.

Since public proceedings adjourned in September, we have been working to ensure that all necessary documents are available on our website. Today, we have added a number of documents including Participant submissions, outstanding summaries, and two additional exhibits.

Throughout proceedings, Participants, including those most affected, families, first responders, governments, and organizations, were able to provide oral and written submissions on evidence entered into the record. The final written submissions from Participants are now posted, as well as submissions from Phase 1 and 2 of the Commission’s work.

We have also issued an order marking two exhibits. The order is available on the website. It directs that two documents deemed appropriate to include in the Commission’s public record but received after the last public proceeding date be marked as exhibits. These two exhibits are available in the source materials library.

As you may know, throughout our process we have been summarizing documents that contain particularly sensitive information, for example, graphic content, material that may be subject to copyright rules or personal health information. The original source materials were accessible to Participants and accredited media under a non-publication undertaking and marked as exhibits. Some outstanding summaries are now available to the public in the source materials libraries. Links in Foundational Documents to summarized materials will take the reader directly to the summary.

We will continue to keep you up to date as we make progress in our work preparing the final report. You can sign up to receive these updates by visiting the home page of our website. Please continue to stay engaged and prepared to help put the coming recommendations into action. We thank everyone for their continued commitment and interest in the work of the Commission.

We appreciate that this material continues to be difficult. If you or someone you know needs help, please make use of the wellness support resources listed on our website.
