Iroquoians become recognizable in the archaeological record of southern Ont
ario about AD 500, with the appearance of Princess Point sites and maize ag
riculture in the lower Grand River valley. After AD 1000, Iroquoians lived
in longhouse villages situated in the interior, north of Lake Erie, Lake On
tario, and the St. Lawrence River. This synthesis of the Iroquoian occupati
on of southern Ontario prior to European contact focuses on origins, settle
ment patterns, demography, subsistence, and sociopolitical organization. It
highlights the significant contributions to Iroquoian archaeology that hav
e been made by government and private consulting archaeologists over the la
st two decades.
