I'm going from memory without naming names, but it's all on the website. There is a university professor in Edmonton who teaches public law and was a former member; a former assistant deputy minister of immigration who has a long-standing high reputation; the former president of the Canadian Council for Refugees; Mr. Ron Ellis, who was a chair of a tribunal in Ontario, now known as the Workplace Safety and Insurance Board Ontario--he has a doctorate, is a specialist on tribunals, and has run a tribunal; and Beverly Nann, former president of the Vancouver Asian Heritage Month Society.
I've tried as much as possible to have people of different backgrounds. The person who presides, and was elected from among themselves, is a former assistant deputy minister of human resources and has worked in human resources in the private sector.
