Inter-corporate Ownership

Tables: 61-517-X
Description: The Inter-corporate ownership product is the most authoritative and comprehensive source of information available on corporate ownership; a unique directory of "who owns what" in Canada. It provides up-to-date information reflecting recent corporate takeovers and other substantial changes. Ultimate corporate control is determined through a careful study of holdings by corporations, the effects of options, insider holdings, convertible shares and interlocking directorships. The number of corporations that make up the hierarchy of structures totals approximately 50,000.

The information that is presented is based on non-confidential returns filed by Canadian corporations under the Corporations Returns Act and on research using public sources such as internet sites. The data are presented in an easy-to-read tiered format, illustrating at a glance the hierarchy of subsidiaries within each corporate structure. The entries for each corporation provide both the country of control and the country of residence.

The product covers every individual corporation that is part of a group of commonly controlled corporations with combined assets exceeding 600 million dollars or combined revenue exceeding 200 million dollars. Individual corporations with debt obligations or equity owing to non-residents exceeding a net book value of 1 million dollars are covered as well.

Notes: As of June 17, 2021, the Inter-Corporate Ownership publication will release on an annual rather than quarterly basis.

The Corporations Returns Act was adopted by Parliament in April 1962 with the purpose of collecting information necessary to determine the extent and effect of non-resident ownership and control of corporations in Canada.

The data disseminated in the Inter-Corporate Ownership (ICO) product is not confidential, as it is collected in Schedule I – Ownership under the authority of the Corporations Returns Act, C-43.
