In the book, Ensouling Our Schools by Jennifer Katz, there is a good suggestion on when to share certain aspects of Truth and Reconciliation.
Treaty Education can begin in Kindergarten. Learning that Canada was formed through cooperation and partnership, and that the partnership then began to struggle, is not traumatic. Children understand that friends don't always get along.
The dark part of our history, though - the forced resettlements and attempts at assimilation, removal of human rights, residential schools, and ongoing racism and discrimination should not be taught until students are emotionally ready to manage them.
