Land Acknowledgement

With utmost respect and awe, we acknowledge the vast and breathtaking expanse of Turtle Island, where the interconnected lands and waters have sustained abundant life for countless generations. We also acknowledge and honour the Indigenous Peoples of Turtle Island who, for thousands of years, lived in harmonious balance with the Earth’s ecosystems, fostering profound insights and wisdom about the intricate relationships within the natural world.

We are committed to learning more about the painful history and intergenerational trauma brought by our settler ancestors, and the past and current systems of oppression and marginalization that extend the injustices. In this learning process we commit to unlearning, listening, and forging new relationships of reciprocity for healing and justice, on our path to a just, beautiful and regenerated world for all. Through these connections, we aim to contribute to the healing regeneration that is urgently needed for all.
