Canada’s leading litigation firm continues to add to its collective experience and knowledge with the addition of Devyn Noonan.
Devyn Noonan studied at the University of Toronto Faculty of Law. She was deeply involved in the school’s mooting community, graduating with the Stephanie Fleur Couzin Medal for Mooting. In her final year of law school, Devyn served as a member of the University of Toronto’s Moot Court Committee where she acted as a co-Chief Justice of the Grand Moot, developing a moot problem that was ultimately argued in front of a panel of distinguished judges. Devyn was also extensively involved in moot coaching during her time in school. In 2019, she coached a team of four students in the Gale Cup who won top prizes in both oral and written advocacy.
Welcome, Devyn!
