Stéphane Grenier is a nationally known mental health innovator, advocate, speaker and entrepreneur who was appointed to the Order of Canada in 2018. He retired from the Canadian military as a Lieutenant Colonel after serving 29 years. He participated in several overseas missions, most notably nine months in Rwanda in 1994/95, and six months in Kandahar, Afghanistan in 2007.
Faced with his own undiagnosed Post-Traumatic Stress Disorder (PTSD) upon return from Rwanda, he took a personal interest in the way the Canadian Forces was dealing with mental health issues. In 2001, he coined the term Operational Stress Injury (OSI) and conceived, developed, implemented and managed a government-based national Peer Support program for the Canadian military.
In the spring of 2012, he retired from the military and created Mental Health Innovations (MHI), a social enterprise dedicated to developing non-clinical mental health interventions as a complement to traditional clinical care. More recently, in 2016 he launched a second company to implement and deliver peer support services within in-patient mental health units at the provincial health care system level.
His autobiography, After the War: Surviving PTSD and Changing Mental Health Culture, was published by University of Regina Press and released in February of 2018.
