This Sunday is September 15th and it marks 150 years since Treaty 4 was signed between the Cree, Assiniboine, Saulteaux peoples and the Crown. The agreement covers about 195,000 square kilometers of territory, including most of southern Saskatchewan. Let us use this occasion to educate ourselves, celebrate the rich cultures of the First Nations involved, and renew our commitment to fostering positive relationships based on respect and understanding.
