ISC register software for federal CBCA corporations.
Federal corporations must maintain a register of individuals with significant control — and since 2024, file ISC information with Corporations Canada. Corpbook keeps the internal register accurate and confirmed so it lines up with what you file.
Not legal advice
What the CBCA ISC register requires.
The federal requirement has four moving parts — who counts, what you collect, how often you confirm it, and what now gets filed publicly.
Who counts as an ISC
An individual with significant control holds, directly or indirectly, 25% or more of the shares by value or votes — or has significant influence over the corporation without owning a majority. Individuals acting jointly are assessed together.
What must be collected
Name, date of birth, address, jurisdiction of tax residence and citizenship, the date significant control began and ended, and a description of how that control is exercised.
How often it’s confirmed
The register must be updated within 15 days of learning of a change, and the corporation must take reasonable steps at least once in each financial year to keep it accurate and complete.
What is filed federally
Since the 2024 amendments, CBCA corporations file ISC information with Corporations Canada, and a defined subset is made publicly accessible. Your internal register and the federal filing must agree.
The 2024 amendments raised the stakes.
Maintaining the register internally is no longer the end of the obligation. CBCA corporations now file ISC information with Corporations Canada, and a defined subset is made publicly searchable — part of Canada’s move toward a public beneficial-ownership registry.
That makes accuracy non-negotiable: the internal register and the public filing have to agree, and gaps are far more visible than they used to be.
Keep the internal record straight, alongside the filing.
Corpbook maintains the complete ISC register — including the fields that are not made public — so your federal filing rests on a record you can actually stand behind.
Build the register from share data
Corpbook derives likely ISCs from your shareholdings and share classes, including indirect and combined control, so you start from evidence rather than memory.
Keep the internal record current
Maintain the full ISC register — including the fields not made public — in a structured, permissioned, access-controlled record that mirrors what you file federally.
Track confirmations and changes
The 15-day update window and the annual reasonable-steps review are tracked and reminded, with every confirmation written to the audit log.
Stay aligned with the federal filing
Corpbook is your source of truth for the underlying record, so when you file with Corporations Canada the internal register and the public filing tell the same story.
CBCA ISC register questions.
- What is an ISC register under the CBCA?
- It is the register of individuals with significant control that federal corporations governed by the Canada Business Corporations Act must maintain. It records the individuals who ultimately own or control the corporation and how that control is held.
- What changed with the 2024 CBCA amendments?
- The amendments require CBCA corporations to file ISC information with Corporations Canada, with a defined subset made publicly searchable, in addition to maintaining the internal register. The intent is greater beneficial-ownership transparency. Corpbook helps you keep the underlying record accurate; confirm filing specifics and timing with your lawyer or corporate registry agent.
- Does Corpbook file with Corporations Canada for me?
- Corpbook is the system of record for your internal ISC register and supporting evidence. It keeps that record structured, confirmed, and audit-ready so the federal filing is straightforward, but it is not a substitute for legal advice or your registry filing process.
