This update shares a recap of this week, including information discussed during witness testimony, as well as details surrounding the upcoming break in public proceedings.

What Happened This Week

This week, we heard testimony from two senior RCMP officers. First, Chief Superintendent Darren Campbell, who served as Support Services Officer for RCMP H Division during the mass casualty. He spoke to his experience and roles, information management during a critical incident, public communications during and after April 18 and 19, 2020, post-event learning, and further context regarding his involvement during the mass casualty. We then heard from Chief Superintendent Chris Leather, who was Criminal Operations Officer for the RCMP in Nova Scotia at the time of the mass casualty. He discussed his activities on April 18 and 19, 2020, post-event communications, internal and inter-agency communication after the mass casualty, the establishment and activity of the Issues Management Team, and lessons learned. Both officers spoke to their experience and roles, and information management during a critical incident, and responded to questions from the Commission counsel and Participant counsel.

Recordings of this week’s proceedings are available on the Commission website, so you can watch public proceedings and follow our work at a time that works best for you.

Proceedings Resume August 22

Proceedings will resume the week of August 22, when we will hear from two senior RCMP witnesses: retired Assistant Commissioner Lee Bergerman and Commissioner Brenda Lucki. In the meantime, the Commission’s work will continue, including preparing for the coming witnesses and for the activities focused on developing recommendations to help keep communities safer.

Please note, the next update will be sent the week before public proceedings resume.
