The Ontario Science Centre operates on the ancestral lands and territories of the Haudenosaunee Confederacy, the Wendat peoples and the Anishinaabek Nation, which includes the Mississaugas of the Credit First Nation and the Chippewa. We acknowledge this land is home to many diverse First Nations, Inuit and Métis peoples. We are grateful to work with, learn from and partner with Indigenous communities in peace, friendship and respect.
