Over the past year, Canada has seen a significant increase in enforcement across all areas of competition law, including misleading advertising, mergers, abuse of dominance, and pricing practices. Important developments have also arisen in competition class actions, criminal investigations, and foreign investment review, and the Competition Bureau has proposed to revise its own substantive guidelines for evaluating the competitive effects of mergers. To examine these developments, the Canadian Bar Association held its annual competition law conference in Gatineau, Québec on 5-7 October 2011. NERA sponsored the opening cocktail reception held on Wednesday evening, 5 October. The following day, NERA Senior Vice President Dr. Graeme Hunter served as a panelist for a session entitled "The Great Cartel Experiment." This interactive session explored when empirical tools can be used to detect cartel behavior and some of the conditions that make such agreements effective.
