Members of Xi Delta Theta are committed to giving back to the Ottawa community through our philanthropic and volunteer efforts. We support a number of organizations, at least once every month. The organizations include: Big Sisters of Ottawa, The Canadian Cancer Foundation, The Ottawa Mission, Christie Lake Camp, The Humane Society and Interval House. Our main charity is the Canadian Cystic Fibrosis Foundation, for which we throw an annual pub night to raise money for cystic fibrosis research in honour and memory of Amelia Lee L'Homme, a sister who passed away during her active membership due to the disease.
