Up to 400 people from as far away as Montreal and Michigan are expected to attend this weekend's Aamjiwnaang Water Gathering and Toxic Tour.
Spokesperson Vanessa Gray says they're focusing on water, and the health impacts nearby industry has on the environment and health of their community.
First Nations culture says they have a sacred responsibility to protect the water, realizing that neither they, nor industry in the Chemical Valley are going anywhere.
"We will have to figure out another way where Indigenous Peoples have the right to consultations, the right to decision-making on our traditional territories," says Gray. "The system is built on white supremacy and this is what we are speaking out against and this is why this gathering is Indigenous knowledge -focused."
The community is invited to take part in Sunday's Toxic Tour that begins at noon at Rainbow Park.
Gray says a walk through Chemical Valley gives a new understanding of what the First Nation experience on a day to day basis.
