On March 4, 2020 the honourable Jacques G. Bouchard of the Superior Court of Québec released a judgment in the long-standing class action Lalande c. Compagnie d'Arrimage de Québec ltée.

In this case, residents of the La Cité-Limoilou sector of Quebec City filed an action against Compagnie d'Arrimage de Québec because of environmental contamination in their neighbourhood, allegedly caused by its operations at the Port of Quebec. The residents complained of dust found in their neighbourhood and allegedly impacting the air quality, and causing nuisance and health risks.

The arguments before the Superior Court of Québec took place over a period of almost four months, and relied heavily on the testimony of scientific experts. In his judgment, Justice Bouchard rejected the class action in its entirety, citing the validity of the defendants' arguments and scientific evidence provided in testimony, that the contributions of the port activities to the alleged disorders was negligible.

Compagnie d'Arrimage de Québec is a prominent marine terminal operator and stevedore based in Quebec City.

McCarthy Tetrault advised Compagnie d'Arrimage de Québec with a team led by Michel Gagné and David Roberge.
