  • Entitlements Information services

    As the nominee security holder of record for most Canadian securities, CDS is first to receive data from Canadian issuers and their transfer agents. This makes CDS the authoritative source of information on Canadian entitlements and corporate actions, facilitating distribution to the marketplace via the following services:

    CDS Bulletins, Enhanced Bulletins and Bulletins Select
    Updated throughout the day, Bulletins provides subscribers with consolidated event data. The Enhanced Bulletins service appends related issuer documents and the Bulletins Select service lists all corporate actions relating to mutual fund and limited partnership issues by tax reporting type (T3, T5 or T5013). 

    CDSX Entitlements Data Feed provides a daily batch file accessible through file transfer protocol (FTP) while CDS Entitlements Messaging provides real-time event data reported through SWIFT messages. CDSX Entitlements Data Feed and CDS Entitlements Messaging Information can be relayed directly to intermediaries and their customers without manual intervention.
