This plaque is part of a campaign started in 2020 by the Royal United Services Institute of Regina, a local organization of civilians and retired military personnel, to install a series of twelve commemorative plaques around the cenotaph. It was unveiled on July 27, 2021. The plaques explain Canada's wartime history.

The D-Day Plaque commemorates Canadians who landed on the beaches of Normandy on D-Day, 6 June 1944, and helped begin the liberation of Western Europe.
