A memorial service is planned for Sunday in central Nova Scotia to honour the 22 people killed by a lone gunman one year ago.

The closed service at Truro’s First United Church, which will be live-streamed on Facebook and local media, is slated to begin at 3:00 p.m. local time.

A province-wide moment of silence will be observed as the ceremony begins, and the service is expected to feature several musical performances and speeches from spiritual teachers and political leaders.

Premier Iain Rankin is scheduled to attend the event, organized by the Nova Scotia Remembers Legacy Society.

The anniversary was also expected to be marked by a peaceful march to the R.C.M.P. detachment in nearby Bible Hill, where some of the victim’s relatives planned to express their dismay with the Mounties’ response to one of the worst mass killings in Canadian history.

The R.C.M.P.’s commanding officer in Nova Scotia, Assistant Commissioner Lee Bergerman, issued a statement saying the police force would observe a moment of silence at 2:00 p.m. on Monday to honour the victims, including R.C.M.P. Constable Heidi Stevenson, who was fatally shot by the gunman.
