Multijurisdictional Disclosure System MJDS
A Canada–U.S. arrangement letting eligible issuers file in the other country largely using their home-country disclosure documents.
What it is
The Multijurisdictional Disclosure System (MJDS) is a 1991 arrangement between the U.S. SEC and Canadian securities regulators that reduces duplicate paperwork for cross-border offerings and reporting. It lets eligible large Canadian issuers offer securities and report in the United States using documents prepared mainly under Canadian rules — for example, filing an annual report on SEC Form 40-F built from their Canadian disclosure. A reciprocal path exists for qualifying U.S. issuers entering Canada.
Why it matters
MJDS is why many big Canadian companies can be dual-listed in the U.S. without preparing a fully separate U.S. disclosure set, lowering cost and speeding up listings. For an investor, it explains why a Canadian issuer's U.S. filings may look like its Canadian ones, and where to find them. It applies mainly to seasoned, larger issuers, not small or new companies.
How it's calculated
This is a concept, not a calculation. To use it, confirm the issuer qualifies (a Canadian foreign private issuer with a sufficient continuous-disclosure history, generally at least 12 months) and then locate its MJDS filings, such as Form 40-F, on the SEC's EDGAR alongside the Canadian originals on SEDAR+.
