Quick Summary

Teiaiagon was a settlement site occupied by the Seneca people by the 1660s, located at the mouth of the Humber River in what is now Toronto, Ontario, Canada. This area was historically a significant trade route, known as the Toronto Passage, connecting the Humber River to Georgian Bay. Before European arrival, various First Nations peoples inhabited the region, utilizing this passage for trade. The dynamics of these relationships changed with the arrival of Europeans, leading to complex alliances and conflicts, further impacted by the introduction of firearms and diseases. By the end of the 17th century, the Seneca abandoned Teiaiagon, and the Mississauga (Ojibwa) occupied the area.1
