Depending on how your corporation is incorporated, it may need to maintain — and in some cases disclose — a register identifying the real, individual people who actually own or control it. These rules exist alongside your normal corporate records and are separate from your minute book's ordinary shareholder register. They're often called beneficial ownership or "transparency register" rules, and which set applies to your corporation depends on whether it's incorporated federally or in Ontario.

This is a genuinely fast-moving area of Canadian corporate law. Both the federal government and Ontario have introduced beneficial ownership transparency requirements in recent years as part of a broader effort to combat money laundering and improve corporate transparency, and the details have been adjusted more than once since they were first introduced. Treat what follows as a general orientation, not a substitute for confirming the current rules that apply to your specific corporation.

The Basic Idea Behind Both Regimes

Both the federal and Ontario regimes work from the same underlying concept: a corporation must look past its formal share registry and identify the individual human beings who actually own, control, or significantly influence it — often referred to as "individuals with significant control." The goal is to prevent a corporation from being used to hide the identity of its real owners, including through nominee arrangements, layered holding structures, or complex voting arrangements.

Which Regime Applies to Your Corporation

A corporation is governed by one regime or the other based on where it's incorporated, not based on where it operates. An OBCA corporation doing business across the country is still governed by Ontario's rules on this point; a CBCA corporation headquartered in Mississauga is still governed by the federal rules.

Because this table describes general architecture and both regimes have changed more than once since introduction, don't rely on it for the precise mechanics of your own filing or disclosure obligation — confirm the current rules with a lawyer or directly through the applicable government source.

Why This Matters Even If Nobody Ever Asks to See It

Failing to maintain a required beneficial ownership register is a compliance gap that tends to surface at the worst possible time — during a financing, a sale of the business, a regulatory review, or a request from a FINTRAC-regulated counterparty (like a bank) that is itself required to verify who owns the corporations it deals with. A missing or out-of-date register is exactly the kind of issue that can slow down or complicate a transaction that otherwise has nothing to do with money laundering.

Practical Steps

  1. Confirm which statute your corporation is incorporated under — CBCA or OBCA — if you're not certain.
  2. Identify the individuals who actually own or control the corporation, including through indirect ownership or voting arrangements, not just the names on your share certificates.
  3. Set up or update the register your governing statute requires, and build a habit of revisiting it whenever ownership or control changes.
  4. Ask a corporate lawyer to confirm you're meeting the current version of the rules — this is an area where "current" genuinely matters.

Frequently asked questions

Does a small, closely held corporation still need to worry about this?

Yes. These rules generally apply based on incorporation type, not company size — a two-person numbered company is typically just as subject to the applicable regime as a larger corporation. Don't assume a small corporation is automatically exempt.

What if my corporation has already changed hands or restructured since it was incorporated?

The register is meant to reflect who actually controls the corporation now, not who controlled it at incorporation. Any change in ownership or control should prompt an update, and if your corporation hasn't kept this current, it's worth having a lawyer review it.

Can I just keep this information informally, without a proper register?

Both regimes contemplate a properly maintained record, not an informal understanding of who owns what. Given how often this comes up during financing or sale due diligence, treating it as a real corporate record — not an afterthought — is the safer approach.

Does converting from a CBCA to an OBCA corporation (or vice versa) change my obligations?

Yes, in principle — you would move from one regime to the other. If you're considering continuance from one jurisdiction to another, this is one of several corporate-law consequences worth discussing with a lawyer before you file.
