Born in Ottawa on 22 April 1932, Yvon Dubé attended the Académie De La Salle. After obtaining a business administration certificate from the University of Ottawa, he went on to train as a Certified Professional Purchaser (CPP). He worked in turn for the City of Ottawa (12 years), the City of Vanier (2 years), the University of Ottawa (12 years) and the National Arts Centre (12 years), as purchasing clerk, purchasing manager and manager, supply and services. He and his wife, Madeleine Boivin, have four children. During his career, he was president of the Ottawa branch of the Purchasing Management Association of Canada (PMAC), then member of its national Board of Directors. He was also a member of L’Institut culturel et social de Vanier, which was renamed Le Centre francophone de Vanier in 1992, and served as its president from 1988 to 1991. He retired in 1991 and ran for the City of Vanier municipal council. He was elected to three terms and served on numerous committees. In September 1998, he persuaded the municipality and the Vanier Business Improvement Area Committee to implement a mural painting project, and became the founding president of an organization called PubliArt Vanier. Between 1998 and 2010, with the support of numerous public and private donors, this group has been responsible for 38 mural paintings in Vanier. Some were inspired by old photos depicting local history, while others sprang from the imagination of contemporary artists and their love of colour.
