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 September 11, 2021. The plaques explain Canada's wartime history.

The Afghanistan plaque commemorates the more than 40,000 Canadians who served in the region. This was the largest deployment of our troops since the Second World War. The conflict lasted more than 12 years— the longest in Canada's history.
