Land Acknowledgement

We acknowledge that our school, located in Ottawa, is on the un-ceded, un-surrendered ancestral territory of the Anishinaabe Algonquin Nation whose presence here reaches back to time immemorial.

We recognize the Algonquins as the customary keepers and defenders of the Ottawa River Watershed and its tributaries.

We honour their long history of welcoming many Nations to this beautiful territory and we thank the past, present and future caretakers of this land for their stewardship.
