Mississauga First Nation is signatory to the Robinson Huron Treaty of 1850 and resides within its traditional territory. The community is located at the mouth of the river which shared its name, The Mississaugi. Spoken in the Anishnaabemowin language, it is Misswezhaging, which means “many outlets”. Although the community is located with the “reserve” boundary, the Traditional Territory extends towards the Huron Watershed.

Mississauga ancestors and current Mississauga’s travel the extent of the Mississaugi River utilizing its abundant resources. The river begins at Lake Huron and extends as far as Bark Lake and beyond. Mississauga First Nation descends from the Anishnawbek Nations that settled throughout the Lake Huron watershed long before the arrival of the French and British.
