The bureau reviews mergers but does not necessarily approve them. It's more a question of whether or not we oppose them or challenge them.
In recent years, there were some mergers that we did not challenge because we didn't have the evidence. Others—for example, Loblaws' acquisition of Shoppers, Sobeys' acquisition of Safeway, or even before that, the acquisition of Provigo by Loblaws—were cases in which we had remedies and divestitures, the sale of stores or assets, to try to preserve competition.
