HALIFAX -- The joint federal-provincial inquiry into the April 2020 tragedy in Nova Scotia made its first public presentation Thursday, and announced who will be participating in its proceedings. The Mass Casualty Commission is tasked with examining the events leading up to and including April 18 and 19, during which a gunman killed 22 people in over a 13-hour rampage throughout a number of Nova Scotia communities. In March, the Commission issued a call for applications from individuals and groups with direct interest in the subjects being examined by the inquiry. In a news release, the Commission says it received 60 applications for participation. In Thursday's virtual announcement, it released the names of individuals and organizations that will be part of the proceedings.
