Léonie Gagné


Senior Associate

Léonie Gagné is a member of the Litigation Group of the Montreal office of Lavery Lawyers. She practices mainly in insurance law, product liability as well as civil and professional liability. She acts both for plaintiffs and defendants.

Ms. Gagné has a strong interest in all the technological developments that are susceptible to have impacts on the insurance industry and on the civil liability of persons and manufacturers in Quebec. More specifically, she has been following the progress of both domestic and international legislation pertaining to autonomous vehicles and is fascinated in general by everything that relates to the driving of automated vehicles.

Before beginning her legal studies, Ms. Gagné worked for more than ten years as a classical ballet dancer in Toronto. For several seasons, she performed for the prestigious National Ballet of Canada.

In 2010, she completed a Certificate in Public Relations at Ryerson University, in Toronto, and in 2011, following her official retirement from the arts world, Ms. Gagné received a major grant from the Dancer Transition Resource Center to support her during the completion of her legal studies.
