As a long-standing member of the OAS and the Ottawa Chapter, Peggi was a driving force behind the development of a public archaeology component of the Chapter's activities. The commitment and creative enthusiasm introduced by Peggi,  led to a broadening of programme mandate and a continuing public interface with the regional communities of Eastern Ontario.

Over the past ten years, the Ottawa Chapter has developed an active public archaeology programme in Eastern Ontario, working with provincial parks, municipal agencies and the school system. The Ottawa Chapter is aware that many OAS members, institutions and organizations work diligently towards the preservation and advancement of archaeology through activities, programmes and formal educational studies.

The recognition of these contributions through the official award process of the OAS is now possible with the "Peggi Armstrong Public Archaeology Award".
