The Ontario Archaeological Society is formed of a parent body and a number of local chapters in various cities in Ontario. The London Chapter represents the regional interests and concerns of the archaeological community in Southwestern Ontario, by providing field activities, social events, and advocacy opportunities. The chapter has sponsored a number of research projects over the years centered on local archaeology. For those interested in the archaeology of Southern Ontario a suggested reading list has been assembled recently.

A series of monthly meetings is held on the second Thursday of each month from September to April (no December meeting). The meeting starts at eight PM and is held at the Museum of Ontario Archaeology located at 1600 Attawandaron Road. Each meeting features a keynote speaker on a wide range of subjects relating to modern Archaeology.
