62-103, The Early Warning System and Related Take-Over Bid and Insider Reporting Issues

Effective date:

March 15, 2000, except for subsequent amendments.

Published by the CSA:

December 17, 1999


The primary purpose of the Canadian standard is to provide exemptions from the early warning requirements, the insider reporting requirement, and related provisions to certain institutional investors that have a "passive intent" with respect to their ownership or control of securities of reporting issuers and to permit those persons to disaggregate securities that they own or control for purposes of those requirements in certain circumstances. This relief is designed to facilitate compliance by financial institutions, pension funds, certain mutual funds, portfolio managers, portfolio clients, underwriters in the course of a distribution, and pledgees.

The amendments announced on February 25, 2016, will, among other things: (i) require disclosure of decreases in ownership, control or direction of 2 per cent or more for security-holders subject to reporting; (ii) require disclosure when a security-holder’s ownership, control or direction falls below the early warning reporting threshold of 10 per cent; (iii) exempt lenders and borrowers, in certain circumstances, from including the securities lent or borrowed for the purposes of determining the early warning reporting threshold trigger; (iv) make the alternative monthly reporting system unavailable to eligible institutional investors who solicit proxies from security holders in certain circumstances; (v) enhance the disclosure in the early warning report; and (vi) further streamline the information required in a news release.
