Paramedics from across Canada learned about PTSD from a high-profile Canadian who witnessed one of the worst genocides in modern history.

Retired lieutenant-general and former Canadian Senator Romeo Dallaire spoke in Edmonton Saturday at the Paramedicine Across Canada Expo (PACE).

Dallaire is the author of the best-selling book Shake Hands with the Devil, which documents his experience as a commander with the United Nations during the Rwandan genocide.

Dallaire spoke to the crowd about the need for better support for PTSD.

“This is mainstream operational effectiveness of your organization,” said Dallaire. “By being able to recognize when you have people who are injured, psychologically and through injury and how you are handling them.”
