Alex O'Reilly

Alex O'Reilly is a partner in Gowling WLG's Montreal office. He practises primarily in Indigenous law, notably for regional and local Indigenous governments as well as Indigenous development corporations. As such, he is called upon to advise his clients on a vast array of legal and strategic matters, including issues pertaining to corporate and commercial law, mining, governance, constitutional law, treaty implementation and employment and labour law.

Alex has worked on a number of court cases - notably for constitutional matters, and has represented clients before the Court of Quebec, the Superior Court of Quebec, the Court of Appeal of Quebec and the Supreme Court of Canada. He also has a marked interest in injunctive proceedings.

In addition, he has developed a niche experience in advising clients with regard to compliance with the regulatory environment in Quebec construction law, notably with regard to the regulations of the Régie du bâtiment du Québec (RBQ) and the Autorité des marchés publics (AMP).  

Prior to joining Gowling WLG, Alex O'Reilly practised at a major international law firm as well as at a boutique firm that specializes in Indigenous law.

He practises in both English and French.
