Land Acknowledgment
We wish to acknowledge that the land on which 5 Otter Editorial operates has been the traditional land of Huron-Wendat, the Seneca, and the Mississaugas of the Credit River for thousands of years. Today, this meeting place is still home to many Indigenous people from across Turtle Island and we are grateful to have the opportunity to work on this land.
