An RCMP officer who was among 22 people killed in the 2020 Nova Scotia mass shooting was remembered today during a regimental service in Halifax that recalled her brave actions. People lined a street leading to the service for Const. Heidi Stevenson, watching as Mounties and municipal police marched, bagpipers and drummers played, and a hearse brought the officer's urn to the ceremony at the Cole Harbour hockey arena.
