The oppression remedy: what a minority holder can do about an unfair sale

Most of what a minority holder can do about a sale they dislike comes from one section. Section 241 of the Canada Business Corporations Act gives them no veto and no price. It gives them the right to ask a judge whether what happened was fair, and gives that judge power wide enough to set the transaction aside, order someone to buy their shares, or liquidate the company.

Key takeaways

  • • “Complainant” is broad: current and former security holders, current and former directors and officers, the Director appointed under the Act, and anyone a court finds “a proper person”.
  • • The test is conduct “oppressive or unfairly prejudicial to or that unfairly disregards the interests of any security holder, creditor, director or officer”.
  • • The court may make “any interim or final order it thinks fit”, including against people other than the corporation.
  • • This is the federal Act. B.C.’s analogue omits “unfairly disregards”, does not name creditors, and adds a timeliness condition.

SECTION 01 OF 08

What the section says

CBCA s. 241 carries the marginal note Application to court re oppression. Subsection (1) is one line: “A complainant may apply to a court for an order under this section.” The force is in subsection (2).

The court must find that an “act or omission… effects a result”, or that the “business or affairs… are or have been carried on or conducted in a manner”, or that “the powers of the directors… are or have been exercised in a manner” — “that is oppressive or unfairly prejudicial to or that unfairly disregards the interests of any security holder, creditor, director or officer”. Then “the court may make an order to rectify the matters complained of.”

Each limb earns its place: an omission counts as much as an act, an affiliate’s affairs are in scope and not only those of the company being sold, and how the directors exercised their powers is itself a ground.

SECTION 02 OF 08

Who can bring it, and which claim

Section 238 defines “complainant” in four limbs: a registered holder or beneficial owner “and a former registered holder or beneficial owner”; “a director or an officer or a former director or officer”; “the Director” appointed under s. 260; and “any other person who, in the discretion of a court, is a proper person”. Closing does not extinguish standing, and the fourth limb is how creditors arrive.

Pick the right vehicle. Where the wrong is to the company — assets sold to an insider under value — the route is the derivative action under s. 239, needing leave and good faith. Treadstone Law notes it runs “in the corporation’s name” with recovery to the corporation, while oppression relief is “generally tailored to the complainant”.

SECTION 03 OF 08

The two questions, and why expectations decide them

The working test is from BCE Inc. v. 1976 Debentureholders, 2008 SCC 69, para. 68: “(1) Does the evidence support the reasonable expectation asserted by the claimant? and (2) Does the evidence establish that the reasonable expectation was violated by conduct falling within the terms ‘oppression’, ‘unfair prejudice’ or ‘unfair disregard’ of a relevant interest?”

Those three labels are not synonyms. “Oppression” is the gravest — “burdensome, harsh and wrongful” (para. 92). “Unfair prejudice” is “less offensive”, its examples including “squeezing out a minority shareholder” (para. 93). “Unfair disregard” is “the least serious” (para. 94). Treadstone Law sets out the same structure in its overview without naming the section: s. 241 federally, s. 248 in Ontario.

The first question does most of the work. Reasonable expectations are “the cornerstone of the oppression remedy”, and the concept is “objective and contextual”: “The actual expectation of a particular stakeholder is not conclusive” (para. 62). And para. 71 is the sentence to sit with — “Actual unlawfulness is not required to invoke s. 241”, which applies “where the impugned conduct is wrongful, even if it is not actually unlawful”. A sale can comply with the articles, the shareholder agreement and the Act and still be oppressive. Treadstone Law draws the same line: a contract claim “asks whether a specific written term was violated”, while an oppression claim “doesn’t require a written agreement at all”.

SECTION 04 OF 08

The remedies are why the section is feared

Subsection (3) opens: “the court may make any interim or final order it thinks fit including, without limiting the generality of the foregoing”. Fourteen examples follow, expressly unconfining — among them “appointing a receiver or receiver-manager”, “directing a corporation… or any other person, to purchase securities of a security holder”, “varying or setting aside a transaction or contract to which a corporation is a party”, and “liquidating and dissolving the corporation”.

A court can therefore undo the purchase agreement itself, which is why a buyer has a stake in how the vendor treated its minority. Treadstone Law says courts have “very broad discretion to craft whatever order is needed” rather than a fixed menu, and calls a buyout “one of the most common remedies Ontario courts order”, with valuation adjustable so “the wrongdoer doesn’t benefit from… the very problems that depressed the share value.”

Two limits. Subsection (6) bars a payment to a shareholder where the corporation “is or would after that payment be unable to pay its liabilities as they become due”. And a shareholder “is not entitled to dissent under section 190 if an amendment to the articles is effected under this section” (s. 241(5)), foreclosing dissent under s. 190; s. 241(7) allows liquidation under s. 214 in the alternative.

SECTION 05 OF 08

The order can run against a person

In Wilson v. Alharayeri, 2017 SCC 39, the Court confirmed that “the oppression remedy contemplates liability not only for the corporation, but also for other parties”, pointing to “any other person” in paragraphs (3)(f) and (g) (para. 29). Liability then has two prongs: the conduct “must be properly attributable to the director because of his or her implication in the oppression”, and “the imposition of personal liability must be fit in all the circumstances” (paras. 47–48).

Liability may be fit where the director “derived a personal benefit…, breached a personal duty or misused corporate power”, though personal benefit and bad faith are “hallmarks” that “do not constitute necessary conditions”. For a controlling shareholder-director who takes a consulting agreement out of the proceeds, that passage is the exposure.

SECTION 06 OF 08

How it changes the way a sale is run

Because the trigger is unfairness rather than illegality, the defensive work is procedural: tell the minority what is happening, in writing; document how the price was tested; disclose every arrangement under which a selling insider takes value that is not a share of the price. None of it is mandated by s. 241; all of it is evidence at the first BCE question.

A minority holder is not automatically owed the same price — Ontario law, Treadstone Law notes, “doesn’t automatically require every shareholder to receive an identical price per share”. But unequal treatment inside one class is different: “if shares of the same class are being treated differently without a legitimate reason… that disparity can support a claim under Ontario’s oppression remedy.”

Exclusion is the other pattern. Section 189(3) already requires a special resolution to sell “all or substantially all the property… other than in the ordinary course of business”, every share voting “whether or not it otherwise carries the right to vote”. Treadstone Law calls exclusion “a serious legal problem, not just a slight”, while challenging a sale demands “genuine unfairness, not just a preference for a different outcome.” Tag-along rights prevent; they do not displace the statute.

SECTION 07 OF 08

The procedure that changes the economics

Section 242 explains why these claims settle. Subsection (3): “A complainant is not required to give security for costs”. Subsection (4): the court “may at any time order the corporation… to pay to the complainant interim costs, including legal fees and disbursements”. The assumption that an eight-per-cent holder cannot fund litigation against a company that can is exactly what that defeats.

Subsection (1) surprises boards: a claim “shall not be stayed or dismissed by reason only” that the conduct “has been or may be approved by the shareholders”. A ratifying vote by the challenged majority is evidence, not an answer, and under subsection (2) the claim cannot be settled “without the approval of the court”. All of it sits against the duty in s. 122(1) to “act honestly and in good faith with a view to the best interests of the corporation”.

SECTION 08 OF 08

Check which statute your company was incorporated under

Section 241 governs CBCA corporations, and the provincial analogues are not identical. Ontario’s Business Corporations Act s. 248(2) names the same three wrongs but reaches conduct that “effects or threatens to effect a result” — anticipatory language the federal section lacks — and its s. 245 complainant definition has three limbs, not four.

British Columbia diverges further. Section 227 is headed Complaints by shareholder and defines “shareholder” to include a beneficial owner “and any other person whom the court considers to be an appropriate person” — so a creditor is not a named category as it is federally. The grounds are “oppressive” and “unfairly prejudicial” only, and s. 227(4) adds a condition the CBCA does not: an order may be made “if it is satisfied that the application was brought by the shareholder in a timely manner.”

So confirm the governing statute and read its section: which wrongs it names, who may apply, whether it reaches threatened conduct, and whether delay is fatal. The reasoning travels; the words do not.
