Jean Leduc has been practicing labour, employment and administrative law for more than thirty years, and is a renowned litigator.

Jean has earned his reputation as an eminent trial lawyer in the fields of labour, employment and administrative law. 

He frequently appears in hearings before grievance arbitrators, the Tribunal administratif du travail (the new Quebec Labour Relations Board) and in the civil courts. 

Jean’s active involvement in several labour conflicts has allowed him to develop a highly valued expertise in the field of injunctions, extraordinary recourses and prerogative remedies before the Conseil des services essentiels, whose powers have since been transferred to the Tribunal administratif du travail. Over the years, he has excelled as a specialist in applications for judicial review. In addition to his talents as a trial litigator, Jean regularly advises employers on employment and labour law issues, particularly with respect to reasonable accommodation in the workplace. 

Jean is currently serving his third consecutive term as chairman of the Barreau de Montréal/​Conférence des arbitres de griefs du Québec liaison committee. This committee, for which Jean acted as president during five years, has jointly produced the first Guide to Best Practices in Grievance Arbitration (French version only) with the Quebec Bar.

A founding partner of Loranger Marcoux in 1991, he has also been recognized for several years in Best Lawyers in Canada”, Lexpert” and Who’s Who Legal” for his professionalism and standards of excellence in the field of labour and employment law.
