Land Acknowledgment

CDS wishes to recognize and acknowledge the land on which the school operates. For thousands of years, these have been the traditional lands of the Mississaugas of the Credit First Nation. We also recognize the traditional territory of the Huron-Wendat, Anishinaabe and the Haudenosaunee peoples who also shared this land.  CDS respects the relationship with these lands and recognizes that our connection can be strengthened by our continued relationship with all First Nations, by acknowledging our shared responsibility to respect and care for these lands and waters for future generations.
