Land Acknowledgement

We acknowledge that the lands on which we gather, and where ACER is headquartered, are part of the Treaty Lands and Territory of the Mississaugas of the Credit First Nation, The Haudenosaunee Confederacy, The Huron-Wendat and Wyandot Nations and the Ojibway/Chippewa peoples. For thousands of years, Indigenous peoples have inhabited and cared for these lands, and continue to do so today. We are grateful to have the opportunity to work on this land, and by doing so, give our respect to its first inhabitants.
