As we approach the National Day for Truth and Reconciliation, we take you inside the ongoing quest to document the children who died in Canada's Indian Residential Schools system. Vinita speaks to Terri Cardinal, director of Indigenous Initiatives at MacEwan University, about the search she led to uncover the unmarked graves of those who perished at the Blue Quills Residential School in Alberta. It's deeply personal and emotional work for Terri, whose own father is a survivor of the school. Terri talks about what she found, how she felt, and what she hopes will come of it. She says the number of unmarked graves across the country is much higher than many of us could have imagined. And she says it’s important to keep shining  a light on the rising numbers, especially with so many Canadians in denial about what really happened at these schools.Visit the Conversation Canada's website for more resources.
