Do You Need Shareholder Approval to Sell Your Business's Assets in Ontario?

A business sale that looks straightforward at the term-sheet stage can stall for a reason that has nothing to do with price or due diligence: the seller corporation's own shareholders never approved it. Under Ontario's Business Corporations Act (OBCA) and the federal Canada Business Corporations Act (CBCA), a sale, lease, or exchange of all or substantially all of a corporation's property, outside the ordinary course of its business, is not something the board of directors can approve on its own. It requires shareholder approval — and if that approval is missed, rushed, or handled informally, it can expose the transaction to a dissenting shareholder's claim or, in a worse case, an argument that the sale was never validly authorized in the first place.

This rule matters specifically when the transaction is structured as an asset sale — where the corporation itself is the seller of its business assets, as distinct from a share sale where individual shareholders sell their own shares directly. It is one of the more avoidable procedural traps in a business transaction, precisely because it rarely comes up while everyone is focused on price and timeline. It tends to surface later, sometimes in the week before closing, when a buyer's lawyer asks for evidence of shareholder approval and the seller's counsel realizes the resolution was never passed — or that a shareholder who was left out of the conversation is now raising an objection.

Both the OBCA and the CBCA contain an equivalent provision: a sale, lease, or exchange of all or substantially all of a corporation's property, other than in the ordinary course of its business, requires the approval of shareholders by special resolution. In Ontario, this is set out in subsection 184(3) of the OBCA; the CBCA contains a parallel requirement for federally incorporated businesses in section 189.

The key phrase is "other than in the ordinary course of business." Selling inventory, equipment that has run its useful life, or a non-core asset in the normal operation of the business does not trigger this requirement — those are ordinary-course decisions the board can make on its own. What triggers it is a transaction that disposes of the operating business itself, or a large enough share of it that the corporation left behind is no longer, in substance, the same business. A sale of a company's core operating assets to a buyer — the classic structure discussed in our guide to selling a business in Canada — is exactly the kind of transaction this rule is built for.

Neither statute defines "substantially all" with a bright-line number, and that ambiguity is deliberate — it lets courts look past the paperwork to the substance of what is actually being sold. Courts applying this test generally weigh two things together: a quantitative comparison of what is being sold against the corporation's assets as a whole, and a qualitative assessment of whether the sale would fundamentally change the nature of the corporation's business — whether it "guts" the company or leaves it as a shell.

In practice, this means a transaction can trigger the shareholder-approval requirement even if it does not dispose of literally every asset on the balance sheet. If what's being sold is the operating heart of the business — its core revenue-generating operations, key contracts, or principal facility — the requirement can apply even where some peripheral assets are excluded from the deal. Because the test is fact-specific rather than formulaic, sellers should not assume the requirement is inapplicable just because a sale is described as a sale of "the business" rather than "the company," or because some assets are being carved out. That determination should be made deliberately, with counsel, before the transaction is signed — not argued about after a shareholder objects.

Where the requirement applies, ordinary board or shareholder approval by simple majority is not enough. Both the OBCA and the CBCA require approval by special resolution — a resolution passed by at least two-thirds of the votes cast at a meeting of shareholders or, if the shareholders act in writing instead of meeting, a resolution signed by every shareholder entitled to vote on it. Where a class or series of shares is affected differently than others by the proposed sale, that class can be entitled to vote separately on the resolution, even if its shares do not otherwise carry voting rights. The CBCA goes further: every share of a federal corporation carries a vote on the sale, whether or not it otherwise carries the right to vote.

The exact voting mechanics for a particular corporation should always be checked against its articles, bylaws, and any unanimous shareholder agreement — some of these documents raise the bar higher than the statutory minimum, and a shareholders' agreement can impose additional consent requirements of its own. Confirming the applicable threshold with counsel before finalizing deal timelines avoids an unpleasant surprise close to signing.

A shareholder who is entitled to vote on the special resolution but opposes the sale generally has a statutory dissent right — sometimes called an appraisal remedy. A dissenting shareholder who follows the required procedure can require the corporation to pay the fair value of their shares in cash, rather than being carried forward as part of a business that has been sold out from under them.

Dissent rights are technical and deadline-driven: the statutes prescribe strict steps — under the OBCA, for example, a written objection at or before the meeting and a written demand for payment within 20 days after notice that the resolution passed — and a shareholder who misses a step can lose the right to dissent altogether. From the corporation's side, that cuts both ways — a board should not assume dissent rights are a remote risk that can be ignored, because a well-organized dissenting shareholder can genuinely delay or complicate closing, and the corporation should budget for the possibility of a cash payout. This is the same special-resolution and dissent-right machinery that appears in a long-form corporate amalgamation, which likewise requires shareholder approval and gives dissenting shareholders a comparable remedy.

Whether a corporation is governed by the OBCA or the CBCA changes some of the procedural details — most importantly, whether non-voting shares get a vote (under the CBCA every share votes on the sale; under the OBCA a non-voting class votes only if the sale affects it differently from other classes) — but the core requirement is the same under both statutes: a sale of all or substantially all of the corporation's property outside the ordinary course of business needs shareholder approval by special resolution, and dissenting shareholders have a right to be paid fair value. A corporation considering a sale should confirm early which statute it is governed by and build the applicable notice and voting timeline into the transaction schedule, rather than treating it as a late-stage formality.

In our experience, this requirement causes problems less often because sellers disagree about it, and more often because nobody raised it early enough. A few patterns we see repeatedly:

• The board proceeds on its own authority. A closely held corporation with one or two active shareholders sometimes treats board approval as sufficient because "everyone agrees" — until a shareholder who was less involved in day-to-day operations, or who has since fallen out with the others, points out that a special resolution was never actually passed.
• The resolution is drafted, but the vote is never properly held or recorded. A written special resolution in place of a meeting must be signed by every shareholder entitled to vote on it and kept in the minute book. A resolution sitting in a lawyer's draft folder, unsigned, is not an approved transaction.
• A shareholder is missed or notified too late. Notice requirements exist precisely so shareholders can exercise dissent rights within the statutory window. Skipping or rushing notice does not just risk objections — it can undermine the validity of the approval itself.

Any of these can force a deal to pause days before closing while counsel scrambles to cure the defect, and a well-organized dissenting shareholder can use a procedural gap as leverage in a way that has nothing to do with the underlying merits of the sale. Lamba Law's business transactions practice advises sellers and buyers across the GTA on structuring asset sales correctly from the outset — confirming whether the shareholder-approval threshold applies, preparing the special resolution and notices on the right timeline, and addressing dissent rights before they become a closing-week emergency.

If your corporation is considering a sale of its business assets, work through these questions with counsel before you sign a letter of intent, not after:

1. 1.Confirm whether the transaction is structured as an asset sale of the corporation's property, or a share sale of the shareholders' shares — the shareholder-approval analysis in this article applies to the former.
2. 2.Assess, honestly, whether the assets being sold constitute all or substantially all of the corporation's property outside the ordinary course of business.
3. 3.Check the corporation's articles, bylaws, and any shareholders' agreement for voting thresholds or consent requirements that go beyond the statutory minimum.
4. 4.Identify every registered shareholder — under the OBCA, notice of the meeting must be sent to all shareholders, not only those entitled to vote — including any who are less involved in daily operations or whose shares sit in a holding company or nominee name, and build proper notice into the timeline.
5. 5.Prepare the special resolution — and, where a meeting is held instead of a written resolution, the required notice and accompanying materials — early enough that the dissent-rights window does not collide with the closing date.

Getting this sequence right at the outset is far less costly than untangling it once a buyer's lawyer has already flagged the gap. This article is general information, not legal advice for a particular transaction — the applicable threshold and procedure should always be confirmed against your corporation's specific articles, bylaws, and governing statute with counsel.
