Multijurisdictional Disclosure System (MJDS)

A disclosure system that facilitates certain Canadian-U.S. cross-border securities offerings, issuer bids and takeover bids. It is intended to reduce costly duplication of disclosure requirements and other filings when issuers from one country register securities offerings in the other. Under the rules, eligible cross-border offerings are governed by the disclosure requirements of the issuer’s home country.
