Acting on Truth and Reconciliation

The Ontario aggregate industry respectfully acknowledges that the lands on which we operate are located within the traditional territories and treaty lands of diverse Indigenous communities. We honour the longstanding and enduring connection that First Nations, Métis, and Inuit peoples have with these lands, and we recognize their contributions—both past and present—to the stewardship and sustainability of these lands. As we carry out our work, we are committed to fostering respectful relationships, promoting meaningful partnerships, and supporting the principles of reconciliation.
