Can You Prove Who Legally Owns Your Corporation? Most Canadian Founders Can't.

The shareholder register is the legal source of truth for share ownership — and most small Canadian businesses don't have one that would survive due diligence. Here's what's at stake and how to fix it.

If someone asked you right now who owns your corporation — not just who you think owns it, but who legally owns it — could you answer with a signed, dated, properly maintained document? For most small Canadian businesses, the honest answer is no.

The shareholder register is that document. It’s the official legal record of share ownership in your corporation, and every Canadian company is required by statute to maintain one.

What is a shareholder register?

A shareholder register (sometimes called a register of members or share ledger) is the authoritative record of who holds shares in your corporation at any given time. It’s not a spreadsheet you sketch out on incorporation day and forget — it’s a living document that must be updated every time shares change hands.

At minimum, a compliant shareholder register must record:

  • Full legal name of each shareholder
  • Last known address
  • Number of shares held, broken down by class (e.g., 100 Class A Common, 50 Class B Preferred)
  • Date shares were acquired (and the date they were transferred or cancelled, when applicable)

Under the Canada Business Corporations Act (CBCA), the BC Business Corporations Act (BCBCA), and Ontario’s Business Corporations Act (OBCA), maintaining this register is a legal requirement — not a suggestion. It must be kept at the corporation’s registered office and made available to directors, shareholders, and (in limited circumstances) the public on request.

Why does it matter?

Proof of ownership. The shareholder register is the legal source of truth for who owns the company. If a shareholder sells or transfers shares without an updated register, the transfer has no legal effect from the corporation’s perspective. The register controls.

Financing and investment. Every investor doing due diligence will want to see your shareholder register. Gaps, inconsistencies between the register and what founders believe the cap table looks like, or shares that were issued but never formally recorded are red flags that slow or kill deals.

Dividends and distributions. Dividends must be paid to shareholders of record — the people recorded in the register on the record date. If your register is wrong, your dividend payments may be too.

Shareholder disputes. In a dispute over ownership or dilution, the register is evidence. An undocumented verbal agreement about share ownership has no legal weight. The register does.

CRA scrutiny. The Canada Revenue Agency expects share ownership to be consistent across your tax filings, your minute book, and your register. Discrepancies invite questions.

Paper and spreadsheets: the DIY approach

Most small businesses maintain their shareholder register one of three ways:

A physical binder. The traditional approach. A lawyer prepares a formatted share register as part of the minute book setup, and it lives in a binder on a shelf. The problem: every time shares change hands, someone needs to update it — and in practice, almost no one does. By the time a deal triggers due diligence, the binder reflects the state of the company years ago.

A spreadsheet. Better than nothing, but a spreadsheet is not a legal document. It has no audit trail, no version history, no signatures. Two people can edit it simultaneously and produce conflicting versions. It also doesn’t enforce the fields required by statute, so it’s easy to omit a required piece of information without realizing it.

Leaving it to the lawyer. Many founders simply outsource this entirely. Their corporate lawyer maintains the minute book and the register. This works — but it costs $200–$400/hour every time there’s an update, and it creates a single point of failure: if you change lawyers or your lawyer retires, you have to reconstruct everything.

How Corpbook compares to Canadian alternatives

Ownr (by RBC) is the most prominent Canadian incorporation tool. It handles the government filing well and generates basic corporate documents. But Ownr is not a compliance platform — it doesn’t maintain a shareholder register that stays current over time, doesn’t enforce statutory fields, and isn’t designed for ongoing governance. It’s a great place to start; it’s not a long-term records solution.

Traditional law firms offer the highest accuracy when engaged properly, but the economics don’t work for most SMEs. Routine share transfers and register updates become expensive line items. Records are locked in the lawyer’s system, not accessible to founders.

US-based cap table tools are typically built for US corporations and US securities law. They are not designed to model the distinctions in Canadian share structures, do not reference Canadian corporate statutes, and generally don’t produce documents formatted to meet CBCA, BCBCA, or OBCA requirements out of the box.

Corpbook is built specifically for Canadian corporate law. The shareholder register validates the fields required under the applicable statute for your jurisdiction before you save. Every share issuance and transfer is recorded with a date and audit trail. As you record transactions, the register stays current — so when due diligence happens, you’re not scrambling to reconstruct three years of history.

What happens when the register is wrong?

Reconstructing a shareholder register retroactively is possible but painful. A lawyer must review every share issuance and transfer, draft corrective resolutions, and in some cases get current shareholders to sign confirmations. Depending on how long the register has been neglected, the legal fees to clean it up can be substantial — and there are situations where disputes about what actually happened cannot be cleanly resolved.

The register is cheapest to maintain correctly in real time.

Corpbook gives you a shareholder register that updates the moment you record an issuance, transfer, or cancellation — with the cap table, share classes, and ownership history linked together. No more reconstruction projects when a deal lands.
