Canadian corporations are legally required to maintain a set of corporate records — commonly assembled in a minute book — and failure to do so exposes directors, officers, and the corporation itself to penalties, loss of good standing, and significant complications at sale, financing, or audit. Here is exactly what the law says, jurisdiction by jurisdiction, and what that means for your business.

The Legal Foundation: Where the Obligation Comes From

Corporate record-keeping in Canada is a matter of statute, not custom. Whether your corporation was incorporated federally or in a province, a specific section of the governing legislation imposes the obligation. The three most commonly applicable statutes are:

• Canada Business Corporations Act (CBCA) — s. 20, governing federally incorporated corporations
• Ontario Business Corporations Act (OBCA) — s. 140, governing Ontario corporations
• Business Corporations Act (British Columbia) (BCBCA) — s. 42, governing BC corporations

Each statute creates an affirmative duty. A corporation does not have the option to maintain records if it feels like it — the obligation exists from the moment of incorporation and continues for the life of the corporation and, in many cases, beyond dissolution.

If you are unsure what a minute book is or why it matters, see our primer on what a minute book is before continuing.

What Each Statute Requires

CBCA Section 20 — Federal Corporations

Under section 20 of the Canada Business Corporations Act, a corporation must maintain a registered office and keep the following records at that location or another location in Canada approved by the directors:

• Articles of incorporation and all amendments
• By-laws and all amendments
• Minutes of meetings and resolutions of shareholders
• Minutes of meetings and resolutions of directors and director committees
• A register of directors — current and past — including residential addresses and dates of appointment and resignation
• A securities register — recording all issued and transferred shares, including names and addresses of registered holders, the number of shares held, and the dates of issue and transfer
• A register of individuals with significant control (ISC register) — added by Bill C-86 in 2019 (discussed below)
• Copies of any unanimous shareholder agreements (USAs)

The CBCA also requires that financial statements and auditor's reports be retained, and that the corporation keep a copy of any report prepared under the Act.

OBCA Section 140 — Ontario Corporations

Section 140 of the Ontario Business Corporations Act imposes a substantially similar set of requirements for Ontario-incorporated corporations:

• Articles of incorporation and any amendments
• By-laws and any amendments
• Unanimous shareholder agreements
• Minutes of all shareholder meetings
• Resolutions of shareholders passed without a meeting
• Minutes of meetings of directors and director committees
• Written resolutions of directors passed without a meeting
• A register of directors, past and present
• A securities register

Ontario added its own ISC register requirement through provincial legislation that took effect in January 2023 (discussed in detail below).

BCBCA Section 42 — British Columbia Corporations

Section 42 of the Business Corporations Act (BC) sets out a comparable list for BC corporations, with some BC-specific nuances:

• Notice of Articles and any Notice of Alteration
• Any shareholders' agreements that restrict directors' powers
• Minutes of general meetings
• Resolutions of shareholders passed by consent resolution
• Minutes of meetings of directors and committees of directors
• Consent resolutions of directors
• A register of directors
• A central securities register

BC does not currently impose a provincial beneficial ownership transparency register in the same form as the federal or Ontario regimes, though federal reporting requirements under FINTRAC may still apply depending on the nature of the business.

The ISC Register: The Most Commonly Missed Requirement

The register of individuals with significant control — commonly called the ISC register or beneficial ownership register — is the most frequently absent document in Canadian minute books today.

Federal (CBCA): Effective June 13, 2019, all CBCA corporations must maintain an ISC register identifying each individual who:

• Directly or indirectly owns or controls 25% or more of the voting shares or 25% or more of the shares measured by fair market value; or
• Has direct or indirect influence that, if exercised, would result in control in fact of the corporation

For each such individual, the register must record their name, address, date of birth, jurisdiction of residence for tax purposes, and the date they became or ceased to be an individual with significant control. Since January 22, 2024, most CBCA corporations must also file this information with Corporations Canada for inclusion in a public beneficial ownership registry.

Ontario (OBCA): Ontario's ISC register requirement came into force on January 1, 2023. The obligation mirrors the federal regime. Ontario corporations must maintain the register at the registered office or with the corporation's attorney (registered agent). Ontario has not yet mandated public filing of ISC information with a central registry, though this is subject to ongoing legislative development.

If your corporation was incorporated before 2019 (federal) or 2023 (Ontario) and your minute book has never been updated since, there is a near-certainty that your ISC register is missing. This is the single most common gap we see when corporations present minute books for review at a financing or a sale.

Access Rights: Who Can Inspect Your Corporate Records?

Corporate records are not entirely private. Statutes prescribe who has the right to inspect the records and in what form.

Shareholders

All three statutes grant shareholders the right to inspect the corporate records during normal business hours. Shareholders may examine:

• Articles and by-laws
• Minutes of shareholder meetings and resolutions
• The securities register (at minimum, their own entries)
• The register of directors

Shareholders of CBCA and OBCA corporations also have the right to receive a copy of the securities register entry relevant to their own shares on demand.

Directors and Officers

Directors have broad access rights to all corporate records. Officers generally have access to the extent authorised by the directors or necessary for performing their duties.

CRA and Regulatory Authorities

The Canada Revenue Agency has statutory authority under the Income Tax Act to examine corporate records during an audit. If records are missing, incomplete, or unorganised, the CRA may make assumptions that are unfavourable to the corporation. Courts have consistently held that a corporation bears the burden of maintaining adequate records sufficient to support its tax positions.

Regulatory bodies — securities commissions, FINTRAC, provincial registrars — also have inspection authority within their respective mandates.

The ISC Register: More Restricted Access

Unlike the general records, the ISC register has a more carefully controlled access regime. Under the CBCA, access to the register is limited to directors, shareholders, and certain government authorities (including police and tax authorities). The register is not freely open to the general public at the corporate level — though the federal public registry, once fully operational, will change the public disclosure calculus for federal corporations.

Physical vs. Digital Minute Books: Is a PDF Legally Valid in Canada?

This is the question most frequently posed by accountants and newly incorporated business owners who have received their incorporation documents electronically.

The short answer is yes — digital minute books are legally valid in Canada, subject to certain conditions.

The CBCA was amended to expressly permit electronic records. Section 20(4) of the CBCA provides that records may be kept in a form that is capable of being reproduced in intelligible written form within a reasonable time. This is broadly interpreted to include PDF documents stored electronically, documents maintained in a purpose-built software platform, and records kept in structured cloud storage.

Ontario and BC contain similar provisions permitting electronic maintenance of records, provided the records remain accessible and reproducible.

What makes a digital minute book legally valid:

• The records must be capable of being produced in a legible, written form on demand
• Documents requiring signatures (resolutions, share certificates) must either be physically signed and then scanned, or signed using a valid electronic signature complying with applicable e-signature legislation (PIPEDA at the federal level, and provincial equivalents such as the Electronic Commerce Act in Ontario)
• The corporation must be able to produce a hard copy if requested by a shareholder, director, or regulatory authority

A disorganised folder of PDFs is technically digital record-keeping. A purpose-built platform like MinuteKeep ensures that digital records are structured, complete, and auditable — not just technically compliant, but functionally useful when you need them.

How Long Must Corporate Records Be Retained?

Retention periods vary by record type and jurisdiction.

During the Corporation's Life

The articles, by-laws, shareholder agreements, and the registers (directors, securities, ISC) must be maintained for the entire life of the corporation. There is no time limit on these foundational records.

Minutes and resolutions of directors and shareholders must be maintained permanently as well — there is no provision in the CBCA, OBCA, or BCBCA permitting the destruction of board or shareholder minutes after a set period.

After Dissolution

The CBCA requires that records be retained for a minimum of six years following the dissolution of the corporation. During this period, the records should be held by the last director or officer in possession of them, or by a person designated for this purpose.

The OBCA similarly requires post-dissolution retention. Ontario corporations winding up should make express provision for who retains the records and for how long.

Tax Records

The Income Tax Act overlays additional retention requirements. Generally, supporting documents for a tax return must be kept for six years from the end of the last taxation year to which they relate. Where a return has not been filed, the clock does not start. Where an objection or appeal is outstanding, records must be kept until the matter is finally resolved plus the six-year period.

As a practical matter, most corporate lawyers advise clients to retain all corporate records indefinitely. Storage costs on digital platforms are negligible; the cost of missing a record at a share sale or tax audit is not.

Common Gaps: Where Canadian Corporations Fall Short

In practice, most minute book deficiencies fall into a predictable set of categories.

1. Missing ISC Register As discussed above, this is now the most prevalent gap in Canadian minute books. Any corporation incorporated before 2019 (CBCA) or 2023 (OBCA) and not actively maintained will almost certainly lack this document.

2. No Organisational Resolutions The first meeting of the directors — covering the appointment of officers, adoption of the corporate seal, banking resolutions, approval of share issuances, and election to comply with provincial requirements — is often missing entirely. This is sometimes because it was never prepared, and sometimes because it was prepared by the incorporating lawyer but never transferred to the client's possession.

3. Out-of-Date Share Register When shares are transferred informally, by spousal or family transfers, or through shareholder buyouts, the securities register frequently goes unupdated. This creates significant problems at the time of a professional valuation, tax reorganisation, or sale.

4. Unapproved By-laws A corporation's by-laws must be confirmed by shareholders. Many corporations are operating on by-laws that were adopted by directors but never put to a shareholder meeting or shareholder resolution for confirmation.

5. Missing Annual Resolutions Closely held private corporations that do not hold annual general meetings are required under most statutes to pass annual resolutions in lieu of a meeting. These are frequently absent from the records, leaving multi-year gaps.

6. Unsigned Resolutions Electronic signature workflows are increasingly common, but resolutions sometimes circulate for signature and are never returned fully executed. An unsigned resolution has no legal effect.

A Note on Professional Advice

This article summarises the statutory requirements as they appear in the CBCA, OBCA, and BCBCA as of the date of publication. It is intended to provide general information for business owners, accountants, and entrepreneurs. It does not constitute legal advice, and you should consult a qualified Canadian corporate lawyer for advice specific to your corporation's circumstances — particularly if your corporation has complex share structures, unanimous shareholder agreements, or outstanding regulatory issues.
