On July 30, 1974, at the Valcartier Cadet Training Center, an accidental grenade explosion claimed the lives of six cadets and wounded dozens more. In 1975, a rock that was originally near the barracks where the incident took place was used as a cenotaph and placed near the headquarters in the center of the camp. During the 1990s reconstruction of the camp, the rock was moved back to approximately where it was initially, not far from the 1974 accident.
1974 Valcartier Cadet Memorial was erected by the 1974 accident responders and Army Cadet League of Canada.
