# What Rights Does a Minority Shareholder Have?

> Federally and in Ontario and Alberta, a minority shareholder can apply to court for an oppression remedy if the corporation's conduct is unfairly prejudicial to them, can seek leave to bring a derivative action on the corporation's behalf, and can dissent from major corporate changes to be paid the fair value of their shares. These rights exist regardless of how few shares someone holds.

Legal information, not legal advice.

## The oppression remedy is the core protection

**A minority shareholder can apply to court for relief whenever the corporation's conduct is oppressive, unfairly prejudicial to them, or unfairly disregards their interests, and this right does not depend on how many shares they hold.** Federally, [section 241 of the Canada Business Corporations Act](https://laws-lois.justice.gc.ca/eng/acts/C-44/section-241.html) lets a shareholder, acting as a "complainant," ask the court to rectify conduct "that is oppressive or unfairly prejudicial to or that unfairly disregards the interests of any security holder, creditor, director or officer." Ontario has a parallel oppression provision at section 248 of the *Business Corporations Act (Ontario)*, and Alberta has one at [section 242 of the Business Corporations Act](https://kings-printer.alberta.ca/1266.cfm?amp=&amp=&amp=&display=html&isbncln=9780779760664&leg_type=Acts&page=B09.cfm). All three regimes give the court wide latitude once oppression is established: [Corporations Canada's official guidance](https://ised-isde.canada.ca/site/corporations-canada/en/business-corporations/oppression-remedy-guidelines-canada-business-corporations-act) confirms the court can order money damages, appoint a receiver, dissolve the corporation, force the acquisition of the shareholder's securities, or amend the corporation's charter documents.

This is the mechanism that answers most disputes minority shareholders face: being frozen out of information, having their shares diluted unfairly, being excluded from declared dividends, or having the majority direct corporate assets to themselves. The remedy is broad by design because minority shareholders typically have no vote that can change the outcome; the court is the check.

## The right to sue on the corporation's behalf (derivative action)

Where the wrong is done to the corporation itself, rather than to the shareholder personally, the corporation is normally the one that should sue. But if those in control of the corporation are the wrongdoers, they are unlikely to authorize that lawsuit. Federally, [section 239 of the CBCA](https://laws-lois.justice.gc.ca/eng/acts/C-44/section-239.html) lets a complainant apply to court for leave to bring an action "in the name and on behalf of a corporation" or intervene in one already underway. Alberta's equivalent is [section 240 of the Business Corporations Act](https://kings-printer.alberta.ca/1266.cfm?amp=&amp=&amp=&display=html&isbncln=9780779760664&leg_type=Acts&page=B09.cfm), which permits a shareholder to commence a derivative action. This lets a minority shareholder pursue a claim the corporation's own management would otherwise bury.

## The right to dissent and be bought out

When the corporation proposes a fundamental change, such as an amalgamation, a continuance to another jurisdiction, or the sale of substantially all its assets, a shareholder who opposes it is not simply outvoted and stuck. Federally, [section 190(3) of the CBCA](https://laws-lois.justice.gc.ca/eng/acts/C-44/section-190.html) entitles a shareholder who follows the dissent procedure to be paid the fair value of their shares once the resolution takes effect. Alberta's dissent right sits at [section 191 of the Business Corporations Act](https://kings-printer.alberta.ca/documents/Acts/B09.pdf), and Ontario's sits at section 185 of the *Business Corporations Act (Ontario)*. In effect, a dissenting shareholder can exit the corporation for cash rather than remain bound to a transaction they voted against.

## What changes the outcome

These rights are not automatic wins; each comes with conditions that shape whether a court will act:

1. **"Complainant" status still has to be established.** The oppression remedy and derivative action are both only available to a "complainant," which under the CBCA framework includes current and former security holders, directors, and officers, plus anyone the court considers a proper person to bring the application.
2. **The conduct has to cross a threshold.** Ordinary business decisions that happen to disadvantage a minority shareholder, such as a legitimate dividend policy or a good-faith financing round, are not automatically oppressive; the shareholder has to show the conduct was genuinely unfair or prejudicial to their interests.
3. **Dissent has a strict procedure and timeline.** The fair-value payout under the dissent right is only available to a shareholder who follows the statutory steps precisely; missing a step can forfeit the entitlement even if the shareholder validly opposed the resolution.
4. **A unanimous shareholder agreement can reshape these rights.** Where shareholders have signed an agreement restructuring how the corporation is governed, its terms interact with (and can affect the practical exercise of) these statutory protections.

## What a minority shareholder can do next

A minority shareholder who believes they are being treated unfairly has concrete, non-litigation and litigation options depending on the situation: reviewing any shareholder agreement or the corporation's articles for provisions already addressing the dispute (such as a shotgun or buy-sell clause), requesting corporate records the shareholder is entitled to inspect, and, where informal resolution fails, applying to the court that has jurisdiction over the corporation's home statute (federal, Ontario, or Alberta) for an oppression remedy, leave to bring a derivative action, or, where a fundamental change is proposed, exercising the dissent right within the required time limits. Because these are court applications, standard court filing fees apply in addition to any legal costs.

## Frequently asked questions

**How many shares do I need to hold to qualify as a complainant?**

The number of shares does not disqualify a shareholder. Federally, under section 241 of the CBCA, any security holder can apply to court for an oppression remedy, and Ontario's and Alberta's equivalent provisions (OBCA s 248, ABCA s 242) work the same way: it is the conduct complained of, not the size of the stake, that the court examines.

**Can a minority shareholder force the company to buy back their shares?**

Yes, if the shareholder exercises the statutory right to dissent from a major corporate change (such as an amalgamation or sale of substantially all assets) and follows the required procedure. Federally, section 190(3) of the CBCA entitles a dissenting shareholder to be paid the fair value of their shares once the resolution takes effect; Alberta's equivalent is section 191 of the ABCA, and Ontario's is section 185 of the OBCA.

**What can a court actually order if it finds oppression?**

Federally, Corporations Canada's guidance confirms the court has broad discretion, including awarding damages, appointing a receiver, dissolving the corporation, forcing a buyout of shares, or amending the corporation's charter documents. Ontario and Alberta courts have parallel oppression powers under their respective corporations statutes.

**Do I have to sue in the corporation's name myself?**

No. A derivative action lets a shareholder ask the court for leave to sue on the corporation's behalf against wrongdoers, rather than suing personally. This exists federally under section 239 of the CBCA and in Alberta under section 240 of the ABCA.
