Our history

Over more than 30 years, our firm has created and consolidated solid relationships

Over more than 30 years, our firm has created and consolidated solid relationships with businesses and their owners by accompanying them in their local, national and international expansion and providing them with a personalized approach to rigorous strategic and legal advice.

Founded as Boivin O’Neil in 1986 by Valier Boivin, our firm rapidly specialized in business, intellectual property and entertainment law, with a particular focus on financing and M&A transactions for clients in a variety of sectors, including biotechnology, information technology, advertising, entertainment, communications, green technologies, and manufacturing.

When Thomas Desbiens, François Senécal and Karine Lefebvre took the helm in 2005, our firm was renamed Boivin Desbiens Senécal, and then became DSL in 2015.

In January 2017, DSL and LES SERVICES JURIDIQUES LEX OPERANDI INC. merged their activities to provide clients with a broader and more comprehensive spectrum of professional services.

For more than 20 years, the professionals at LES SERVICES JURIDIQUES LEX OPERANDI INC. served a clientele of large corporations, financial institutions, para-public entities, and SMEs. These professionals specialize in dispute resolution and litigation, as well as policy advice in niche areas such as transportation, regulatory, constitutional, securities, corporate and insurance law.

In addition, LES SERVICES JURIDIQUES LEX OPERANDI INC. has developed leading-edge expertise in the development of outsourcing solutions for its clients and partners, including several large professional firms in Canada, which today completes DSL’s service offering.
