OTTAWA — Three Mounties killed in a shooting rampage in New Brunswick were remembered today in Ottawa, along with a Toronto police constable and a Saskatchewan conservation officer who also died in the line of duty.

Hundreds of police and peace officers from across Canada and as far away the U.K. honoured the five slain officers at a memorial held annually for those killed while keeping the country and Canadians safe.

Constables Douglas Larche, Dave Ross and Fabrice Gevaudan were killed and two other RCMP officers were injured on June 4 in Moncton.

Justin Bourque, 24, has since been found guilty of three counts of first-degree murder and two counts of attempted murder in connection with the shootings although he has yet to be sentenced.

Toronto police Const. John Zivicic died last November after his cruiser was involved in a collision.

Saskatchewan conservation officer Justin Knackstedt was killed after being hit by an SUV while he was directing traffic at the scene of a crash in May 2013 near Saskatoon.

Public Safety Minister Steven Blaney told the memorial the officers represented all of those who protect citizens and communities from people who threaten their safety and security.
