In addition to his legal background, Mr. Mazzone was Vice-President for a well-known Quebec transport company and Executive Director of a reputable charitable foundation.


Mr. Mazzone has developed considerable expertise as a transactional lawyer in the field of mergers and acquisitions (with a strong emphasis in the retail sector) in local, national and cross-border matters.
