Fonds is arranged in two series: 1) Personal and professional activities records 1950-1986 and 2) Client files 1958-1984. The fonds includes records relating to Gill's personal and professional and busines life, including personal correspondence and documents regarding his financial and business interests, his hiking and skiing activities, his relationship with professional governing bodies, law student notes, files on labour relations seminars Gill was involved with as a practicing lawyer, and files relating to the administration of the law partnerships of which he was a member. Client files relate to a wide range of matters including labour relations, motor vehicle accident/insurance litigation, employment law, defamation, oil and gas, wills and estates, Hutterite land issues, criminal law and public commissions of inquiry. Labour relations and litigation were primary areas of Gill's practice and labour relations files represent about 50% of the files. His practice dealt with all phases of industrial reiations - certification applications before the Industrial Relations Board, conciliation and arbitration boards, and strike-related court actions. Gill's clients dealt with all major international oil and construction workers unions as well as health care workers unions. The fonds represents a successful post-war legal career in which Gill made a meaningful contribution to change and development of the law in Alberta and in Canada in various ways - through his presence in the labour law scene and the expert advice he could offer to legislators on labour issues, through his arguments in the Supreme Court of Canada on oil and gas cases, and through his work for Hutterite clients relating to the Alberta Communal Property Act. The nature of Gill's practice in which he dealt with many large public and private employers, as well as public boards and commissions of inquiry, was such that many individual cases he dealt with had broader ramifications for Alberta society as a whole.

The fonds consists of correspondence and mechanical drawings concerning Jesse Wilkinson's Wilmow Oil Burner; correspondence concerning Gordon Wilkinson's book-length typescript "Canadian Union Conflicts"; and a poem by Gordon.
