What is a Free Agent?
A Free Agent is an indeterminate Government of Canada employee who has been officially deployed to Canada’s Free Agent Program, which has positions in a couple of Home Departments across Canada’s public service. Free Agents go on continuous assignments throughout the core departments of the federal public service. Free Agents come from many different personal and professional backgrounds but are united by their collaboration skills and ability to hit the ground running.
