The Mass Casualty Commission is an independent public inquiry created to examine the April 18-19, 2020 mass casualty in Nova Scotia and to provide meaningful recommendations to help protect Canadians in the future. On October 21, 2020 the Government of Canada and Province of Nova Scotia each issued an Order in Council (OIC) officially establishing the Commission and announcing the appointment of the three Commissioners and the beginning of this important work.

During the Inquiry the Commissioners will listen, ask questions, and gather information as part of their investigation. At the end of the mandate, in November 2022, they will submit a report containing their findings, lessons learned, and recommendations to help prevent and respond to similar events.
