Catherine Deslauriers



Catherine Deslauriers is a member in the Labour and Employment law group. She has a special interest in construction, occupational health and safety, worker’s compensation (financing and/or compensation of employment injuries), penal law and the management of cases involving medical concepts, such as cases related to disability or absenteeism.

Catherine is often called upon to intervene in investigations being conducted by different public bodies, such as the CNESST, the CCQ and autonomous auditing units like UPAC-CCQ and in investigation conducted by different parity committee. In particular, she has assisted employers in carrying out investigations following serious or fatal workplace accidents. She has also intervened on matters of subjection of construction projects to the R-20 Act. She has been involved in the implementation of work procedures in companies to ensure compliance with occupational health and safety legislation, as well as with auditing and improving internal mechanisms to control risks and dangers present in the workplace environment.

On numerous occasions, Catherine has managed and pleaded cases before the Administrative Labour Tribunal’s (Occupational Health and Safety and Labour Relations divisions), as well as before grievance arbitrators, the Court of Quebec (Criminal and Penal Division and Civil Division) and the Superior Court.

Catherine not only has litigation experience, but she is also ready and willing to accompany employers in their daily handling of workplace injury or occupational disease cases accepted by the CNESST, develop strategies to manage employee absenteeism, including both disciplinary and administrative aspects, as well as employee disability cases, develop strategies to improve the working environment, through policies, forms and training, and by implementing concrete measures and to find solutions to avoid costly disputes and foster agreement between contending parties.

In short, through her past experience in the CNESST’s Occupational Health and Safety Branch, as well her experience in the legal department of an employers’ association in the construction industry, Catherine has developed a special expertise that has proven to be a real asset in many ways.
