The earliest Iroquoian settlement in Toronto occurred around 900 CE. Iroquoian villages during this period were located on high, fortified grounds, with access to wetlands and waterways to facilitate hunting, fishing, trade, and military operations. Iroquoian villages typically lasted a period of 10 to 20 years, before its inhabitants relocated to a new site. Several Huron villages dating back to the 1200s have been excavated in Toronto, including a Huron ossuary in Scarborough. From the 1300s to the 1500s, the Iroquoian inhabitants of the area migrated north of Toronto, joining the developing Huron confederacy. During this period, the Huron confederacy used Toronto as a hinterland for hunting, with the Toronto Passage continuing to see use as a north–south route. The northeast portion of Toronto also held two 14th century Huron burial mounds, known today as Taber Hill.
