This paper examines the incidence of foreign control in Canadian non-financial industries. It focuses on changes in the share of assets and revenues under foreign control over a long-run period during which Canada's regulatory climate shifted from being more restrictive to more liberal in its treatment of inward foreign direct investment. These regulatory changes coincided with a retrenchment and then a resurgence in the activities of foreign multinationals in Canadian industry. We report aggregate results for non-financial industries, along with specific tabulations for the energy sector. More detailed industry tabulations are presented for the 2000-2003 period.
