L & G Branch OGS – Facebook Group

The United Counties of Leeds & Grenville are the traditional territory of Wendat, Anishinaabeg and Haudenosaunee Peoples. The area is home to many First Nations, Inuit and Métis peoples, and we pay respect to all Indigenous people in the region, and recognize the responsibility we all have in protecting the water, air, animals, plants and land on which we live. We do this land acknowledgement as a show of respect to those who took care of these lands before the settlers arrived, to remind us of our obligations, and to reconcile the past and move forward together into the future.
