Canada ISC Public Register: 22 January 2024 Disclosure Requirements

Since 22 January 2024, every federal corporation governed by the Canada Business Corporations Act (CBCA, RSC 1985, c. C-44) has been required to file information about its Individuals with Significant Control (ISC) with Corporations Canada — and for the first time in Canadian federal corporate history, that information is publicly searchable. This change, enacted under CBCA s.21.1 and the related amendments, fundamentally altered the privacy expectations of CBCA shareholders. This deep-dive walks through who counts as an ISC, what must be filed, when, and what the practical consequences are for founders incorporating federally in 2026.

1. Statutory Source — CBCA s.21.1 and the 2022 Amendments

The ISC concept first entered the CBCA in 2019 as an internal-only register kept at the corporation’s records office. The Budget Implementation Act, 2022, No. 1 added the public filing requirement, and the public-facing register went live on 22 January 2024. The current text of CBCA s.21.1 (and the operative regulations) is available in full from the federal Justice Laws Website:

• CBCA full text: https://laws-lois.justice.gc.ca/eng/acts/c-44/fulltext.html

Under CBCA s.21.1, every CBCA corporation other than a “distributing corporation” (broadly, a public company already subject to securities-law disclosure) must:

• Identify each individual with significant control;
• Record prescribed information about each such individual; and
• File that information with Corporations Canada.

Failure to comply carries fines of up to CAD 200,000 (corporation) or CAD 200,000 plus six months’ imprisonment (directors, officers, and shareholders who knowingly authorize, permit, or acquiesce in non-compliance).

2. Who Is an “Individual with Significant Control”?

Under CBCA s.2.1, an individual qualifies as an ISC if any of the following applies, alone or together with related persons:

• Direct or indirect ownership of 25% or more of the voting shares of the corporation, measured by votes;
• Direct or indirect ownership of 25% or more of the issued shares of the corporation, measured by fair market value;
• Direct or indirect influence that, if exercised, would result in control in fact of the corporation; or
• Any combination of the above that meets the 25% threshold.

The concept reaches beyond the share register. Trusts, nominee arrangements, voting agreements, and shareholder agreements that confer control rights all feed into the analysis. A founder who holds only 20% of the shares but has the right to appoint a majority of directors under a shareholder agreement is still an ISC under the “control in fact” branch.

For a young federal startup, the ISC list typically includes each founder, each significant angel investor, and any holding company that itself holds 25%+ — in which case the analysis tunnels through to the natural persons behind the holding company.

3. What Must Be Recorded and Filed

For each ISC, the corporation must record and file:

• Name (current legal name);
• Date of birth;
• Country of citizenship;
• Country of residence for tax purposes;
• Residential address (private — see §4 below);
• Date the individual became an ISC and, if applicable, the date they ceased to be one;
• Description of the significant control (e.g., “holds 40% of common shares” or “has right to appoint two of three directors under shareholder agreement”).

The corporation must take reasonable steps at least once per financial year to identify ISCs and ensure the information is accurate.

4. What Is Public, What Is Private

Not every field is published. The federal regulations under CBCA s.21.1 distinguish between publicly searchable and non-public information. As a working summary:

Individuals may apply to withhold information from public disclosure if its disclosure would create a serious threat to safety or if the individual is a minor or otherwise incapable. The application is to Corporations Canada and is decided on the merits.

5. Filing Deadlines and Triggers

5-1. Initial Filing on Incorporation

A corporation incorporated on or after 22 January 2024 must file its initial ISC information as part of, or shortly after, the incorporation filing. In practice, the Corporations Canada online filing centre prompts the incorporator to submit ISC information at the time of incorporation.

5-2. Annual Confirmation

Each year, alongside the annual return under CBCA s.263, the corporation must confirm or update ISC information.

5-3. Change Filing — 15 Days

Whenever an event causes a change in ISCs (a new investor crosses 25%, a founder leaves, a shareholder agreement is amended), the corporation must update its register within 15 days of becoming aware of the change. The updated information must be filed with Corporations Canada within 30 days of the change.

5-4. Strike-Off Risk

Repeated non-filing of ISC information can result in administrative dissolution of the corporation under CBCA s.212. Revival is possible but costs CAD 200 plus all unpaid annual returns.

6. Comparison with OBCA and BCBCA

The federal regime is now the most transparent in Canada:

Under OBCA s.140.2, Ontario private corporations keep their ISC register internal, available to law enforcement and tax authorities on request. Under BCBCA Part 4.1 (in force from 1 October 2025), British Columbia private companies file their Transparency Register publicly — but BC’s regime is younger than CBCA’s and uses a different portal. For founders concerned about privacy of basic ownership data, OBCA is currently the most private of the three.

7. Practical Workflow for a New CBCA Corporation

Step 1 — Identify ISCs Before Incorporation

During Scrib🐮 intake, the founder lists every shareholder who will hold 25%+ at incorporation, every holding company in the chain, and every shareholder agreement or voting trust that confers control rights. This list is the working ISC roster.

Step 2 — Collect Prescribed Data

For each ISC, collect: legal name, date of birth, country of citizenship, country of tax residence, residential address, and a written description of the significant control. Founders sometimes resist providing date of birth — explain that this field is non-public but mandatory for the federal record.

Step 3 — File at Incorporation

Submit ISC data through the Corporations Canada online filing centre during, or immediately after, incorporation:

• https://corporationscanada.ic.gc.ca/eic/site/cd-dgc.nsf/eng/h_cs01035.html

Step 4 — Calendar the 15/30-Day Change Triggers

Set ongoing reminders so that any future change in cap table, shareholder agreement, or director-appointment rights triggers an internal review within 15 days and a Corporations Canada filing within 30 days.

Step 5 — Coordinate with Annual Return

Confirm or update ISC information with each annual return. The two filings are administratively linked.

8. Frequent Errors

• Treating the federal register like the Ontario register. Ontario ISC information is internal; federal is public. Founders who incorporate federally expecting privacy are surprised when their name and country of residence appear in a public search result.
• Forgetting nominees and trusts. A nominee shareholder is not the ISC; the beneficial owner is. A trust requires identification of the trustee plus the settlor and beneficiaries who have control rights.
• Holding companies “stop” the analysis. They do not. The federal regulations require the corporation to look through any holding company chain to the natural persons at the top.
• Late change filings. The 15-day internal / 30-day filing windows are short. A cap-table change must trigger the ISC update workflow on the same day.

9. Why This Matters for Foreign Founders

A non-resident founder incorporating a CBCA corporation now has their name, country of citizenship, country of tax residence, and an address for service searchable in the Canadian federal database. For founders coming from civil-law jurisdictions where corporate ownership is private (Japan, Germany, France, much of Latin America), this is a meaningful change in expectations. It is not a reason to avoid CBCA, but it is a reason to incorporate knowingly.

If the public-disclosure profile is a problem, OBCA Ontario is the more private alternative — internal register only, no public filing. BCBCA, since 1 October 2025, also publishes Transparency Register information.
