Forestville, a town in the Quebec’s Upper North Shore region, was partially transformed into a Hollywood set during the filming of a TV series based on the best-selling novel The truth About the Harry Quebert Affair. This project was made possible thanks to the efforts and expertise of a team of Langlois Lawyers consisting of François Mainguy, a lawyer, partner, and Pascal Archambault, a lawyer at the firm, who assisted the company that owned part of the filming location in reaching an agreement between it and the producers of the series.
Represented CN in several civil and commercial liability matters.
Acted for the defence in major professional liability cases.
Pleaded precedent-setting cases involving non-unionized employees and latent defects before the Quebec Court of Appeal.
