Chairman of the Board of Directors of De Grandpré Chait, Eric Lalanne has thorough expertise in commercial and corporate litigation. With respect to his administrative functions, he oversees the firm's overall operations while ensuring its strategic objectives are achieved.

His knowledge of the corporate world is immensely helpful in oppression remedy cases where the defense of minority shareholders, and sometimes majority shareholders, requires the intervention of the courts to cease and correct abusive conduct. In the judgment of People Department Stores Inc., he won before the Supreme Court of Canada a landmark decision regarding the duties and obligations of directors and officers of corporations. Many decisions in which he has been involved have shaped the law in Quebec.

Mr. Lalanne also acts in cases of insolvency and restructuring. He counsels and defends our clients' interests concerning the rights and recourses of trustees and creditors against reviewable transactions or directors of insolvent companies. He is proficient in complex financial analyses often associated with large-scale proceedings. Mr. Lalanne is part of the litigation team dedicated to litigation in franchising and distribution matters, and heads the team responsible for the litigation services the firm provides to a major Canadian food distributor.
