On January 1, 2023, amendments to the Business Corporations Act (Ontario) (the “OBCA”) came into effect requiring certain private corporations incorporated under the OBCA to prepare and maintain, at their registered offices or at another place in Ontario designated by the directors of the corporation, a register of individuals with significant control over the corporation. This register must look behind the registered owners of shares and contain information about any individuals who ultimately beneficially own, or have control direction over, sufficient shares of the corporation to have significant control, or who have a controlling influence over the corporation.
