Stéphane Grenier is a nationally recognized leader and retired Lieutenant-Colonel whose 40+ years of experience — from peacekeeping missions in Rwanda, Haiti, and Afghanistan to leading a 50-person mental health consultancy — have shaped a deeply human-centered philosophy of leadership. He helps audiences across all sectors transform their leadership from a skillset into an artform, and harness it as their most powerful tool for employee mental health and organizational resilience.
For over 25 years, Grenier has focused on transforming how organizations design and deliver mental health support, with particular emphasis on integrating large-scale peer support as a complement to clinical care. At the request of the Mental Health Commission of Canada, he led the development of Canada’s National Standards of Practice for Peer Support, and later co-founded the organization now known as Peer Support Canada, the national body responsible for accreditation and certification.
Prior to this, Grenier served nearly three decades in the Canadian Armed Forces, retiring as a Lieutenant-Colonel following multiple international deployments. His lived experience with mental health challenges — including his own — shaped his commitment to more human-centered approaches to both leadership and care, a journey he recounts in his memoir After the War: Surviving PTSD and Changing Mental Health Culture.
In 2012, Grenier founded Mental Health Innovations (MHI), now a leading Canadian organization supporting healthcare systems, workplaces, and public and private sectors through evidence-informed, peer-based interventions. His leadership has been recognized with the Order of Canada, the Meritorious Service Cross, and two honorary Doctor of Laws degrees.
