Omar Khadr is set to speak at a Dalhousie University event Monday night.
Children's Rights Upfront: Preventing the Recruitment and Use of Children in Violence is in partnership with the Roméo Dallaire Child Soldiers Initiative and aims to shed light on the use of children in violence.
The former Guantanamo Bay detainee will be joined by human rights activist and author Ishmael Beah, whose book A Long Way Gone describes his account of being a child soldier during the civil war in Sierra Leone.
"The event is a rare opportunity for public discussion around the complex issue of child soldiers," said the description for the event. "Mr. Khadr and Mr. Beah will highlight their experience in conflict and why they are passionate about the protection of children."
Khadr was accused, as a 15-year-old in Afghanistan, of killing a U.S. soldier and injuring another.
In 2017, the Canadian government apologized to Khadr and paid him more than $10 million for having violated his rights while he was in Guantanamo Bay.
Tonight's event coincides with the International Day Against the Use of Child Soldiers, which is February 12.
