Linda has argued at all levels of court, including before the Supreme Court of Canada. In recent years, she was before the Ontario Court of Appeal or Supreme Court of Canada on important legal issues, including the court's jurisdiction of foreign class members, whether umbrella purchasers (purchasers of the relevant product from non-defendant manufacturers) have a cause of action in a price-fixing claim, and whether the statutory claim contained in the Competition Act provides for discoverability.
