About Numbering System


The Canadian Securities Administrators (CSA), follows a system in which securities regulatory instruments are assigned numbers that indicate the type and subject matter of the instrument.

Under the numbering system, each instrument is assigned a five digit number, with a hyphen appearing between the second and third digit. There are four components to the number assigned to a document:

  • The first digit represents the broad subject area.
  • The second digit represents a sub-category of the broad subject area.
  • The third digit represents the type of the document.
  • The last two digits represent the number of the document within its document type in its sub-category (in sequential order starting at 01).

The documents are divided into nine main subject areas, indicated by the first number. The nine subject areas are:

1 - Procedure & Related Matters
2 - Certain Capital Market Participants (Self-Regulatory Organizations, Exchanges and Market Operations)
3 - Registration Requirements & Related Matters (Dealers, Advisers and other Registrants)
4 - Distribution Requirements (Prospectus Requirements and Prospectus Exemptions)
5 - Ongoing Requirements for Issuers & Insiders (Continuous Disclosure)
6 - Takeover Bids & Special Transactions
7 - Securities Transactions Outside the Jurisdiction
8 - Investment Funds 
9 - Derivatives

If you are looking for a document with a five digit number that starts with 4 (e.g. NI 43-101), you will need to select 4 - Distribution Requirements. Similarly, if you are looking for a document starting with 8 (e.g. NI 81-101), you will need to select 8 - Investment Funds.

A Companion Policy or Form that is related to an Instrument or Local Rule will have the same number as the Instrument or Local Rule to which it relates, followed by “CP” in the case of a Companion Policy or “F” in the case of a Form. If there is more than one Form related to a particular instrument, the Forms will be numbered consecutively (F1, F2, F3, etc.).
