Following his electoral loss, Pratt joined the Canadian Red Cross as a Special Advisor in November 2004. He worked on issues related to conflict prevention, small arms and light weapons and international humanitarian law. During the aftermath of the December 2004 South East Asia Tsunami, he visited Thailand and Sri Lanka where, with the cooperation of the International Committee of the Red Cross (ICRC), he submitted a report to the Canadian Red Cross with recommendations for Canadian aid. In 2006, he helped initiate the Canadian Red Cross’s Auxiliary to Government project. The project sought to improve the cooperation between the Canadian Red Cross and governments at all levels in Canada, especially in the area of emergency management. It emphasized the special and distinct role that Red Cross and Red Crescent Societies have under domestic and international law and the Statutes of the International Red Cross and Red Crescent Movement. The project also sought to obtain new legislation to replace the outdated The Canadian Red Cross Society Act, 1909. As the project leader, Pratt authored a discussion paper entitled: "Toward a Renewed Canadian Red Cross – Forging Stronger Partnerships In Support of a Humanitarian Agenda" and the project’s interim report entitled: "Revitalizing the Framework of Cooperation with Public Authorities".
