Martin started his professional life as an infantryman and paratrooper in the Canadian Army, deploying on United Nations peacekeeping missions to Cyprus, Croatia and Bosnia and serving in Operation Desert Storm during Gulf War One.

Following his fifteen-year military service, he began a twenty-year career in health care as an emergency medical technician. As a registered nurse, Martin provided frontline emergency and critical care in Calgary, Alberta; delivered primary care and public health to the Inuit across the Canadian arctic; led humanitarian assistance and emergency disaster relief missions for non-government organizations in Africa, the Middle East, and the Caribbean; and managed health care centers in the Yukon.

Retired from both the military and healthcare, Martin embarked on a filmmaking career, focused on showcasing humanitarian stories, wildlife conservation and veterans' contributions to society.
