Canada's federal leaders paid their respects Saturday on the eighth anniversary of the attacks at the National War Memorial and Parliament Hill.
Prime Minister Justin Trudeau saying he joins Canadians in paying tribute to Cpl. Nathan Cirillo, who died in 2014 while guarding the Tomb of the Unknown Soldier in Ottawa.
"Today, we remember the selflessness and compassion of bystanders and members of our parliamentary family who acted without hesitation to protect us, and we salute the first responders who put themselves in harm's way to ensure their safety," Trudeau said.
"The National War Memorial was built to commemorate the response of Canadians in times of war. It has since become a symbol of the sacrifice of all our military personnel who have lost their lives in the line of duty. Parliament Hill symbolizes the values that define us as Canadians: freedom, peace, and inclusion. We will always stand up against violence and terrorism to ensure these values are protected."
After killing Cirillo, the gunman, Michael Zihaf Bibeau, stormed Centre Block on Parliament Hill with a rifle and was later taken down by Kevin Vickers, then sergeant-at-arms of the House of Commons.
Trudeau also recognized Warrant Officer Patrice Vincent, who died two days earlier in a separate attack in Saint-Jean-sur-Richelieu, Que.
Conservative Leader Pierre Poilievre also acknowledged the anniversary, , "We mourn the loss of W.O. Patrice Vincent & Cpl. Nathan Cirillo. And we renew our pledge to fight and stand up to terror here at home and around the world."
NDP Leader Jagmeet Singh are with the loved ones of both Cirillo and Vincent, "who tragically lost their lives. As well as all first responders who risked their safety."
Defence Minister said, "We remember them for their service to Canada, and our thoughts remain with their families and loved ones."
