Leluk was born in Hillcrest, Alberta, and educated at the University of Toronto and the University of Wisconsin–Madison. He worked as a pharmacist, and was executive assistant to the registrar of the Ontario College of Pharmacists from 1961 to 1969. Leluk was both a freemason and a Knight of Malta. He also served as President of the Ontario Tae Kwon-Do Association from 1974 to 1983, and was a founding executive director of the Council on Drug Abuse.
