The oppression remedy under section 248 of Ontario's Business Corporations Act lets a shareholder — and in some cases a director, officer, creditor, or other "proper person" — apply to court where a corporation's conduct is oppressive, unfairly prejudicial, or unfairly disregards their interests. Courts look at whether the complainant's reasonable expectations were violated, and can order a wide range of remedies including damages, a forced share buyout, or other relief tailored to the situation.
- The oppression remedy is found in section 248 of the Ontario Business Corporations Act (OBCA).
- Relief is available where conduct is oppressive, unfairly prejudicial, or unfairly disregards a complainant's interests.
- Courts assess whether the complainant's reasonable expectations were violated — not simply whether they are dissatisfied with a decision.
- Shareholders are the most common applicants, but directors, officers, creditors, and other "proper persons" can qualify in the right circumstances.
- Courts have broad discretion, including ordering damages, a forced buyout of shares, or amendments to corporate documents.
- Minority shareholders in closely held Toronto businesses are especially vulnerable to conduct the oppression remedy is designed to address.
What Is Oppressive Conduct?
The oppression remedy, found in section 248 of the Ontario Business Corporations Act, allows a court to grant relief where a corporation's affairs have been conducted, or its powers exercised, in a way that is oppressive, unfairly prejudicial, or that unfairly disregards the interests of a complainant. It is one of the most powerful tools available to a shareholder who has been mistreated by those controlling a corporation.
Importantly, the conduct does not need to be illegal or even a breach of a specific corporate statute — the oppression remedy targets unfairness, which can arise even where the majority has technically complied with corporate formalities. See our shareholder dispute services page for how we handle these matters, or our related guide on partnership disputes if your business is unincorporated.
The "Reasonable Expectations" Test
Ontario courts focus heavily on whether the conduct in question violated the complainant's reasonable expectations — expectations that can arise from the corporation's constating documents, a shareholders' agreement, the history and nature of the relationship between the parties, and industry norms for a business of that kind. Guiding principles courts apply include that any remedy should go no further than necessary to rectify the oppression, and should vindicate the reasonable expectations of the complainant and other stakeholders.
A majority shareholder can follow every corporate formality and still be found to have acted oppressively if the result unfairly disregards a minority shareholder's legitimate, reasonable expectations.
Who Can Apply
Shareholders are the most common applicants, but the OBCA extends standing to any "proper person," which can include directors, officers, creditors, and in some circumstances trustees in bankruptcy or holders of an equity interest — provided they can show a legitimate stake affected by the conduct at issue.
What a Court Can Order
Courts have exceptionally broad discretion under the oppression remedy. Available relief can include:
- Money damages compensating the complainant for the oppressive conduct
- A forced buyout of the complainant's shares (or, less commonly, an order compelling the complainant to sell)
- Amendments to the corporation's articles, by-laws, or a shareholders' agreement
- Appointment of a receiver to manage the corporation's affairs
- In extreme cases, an order dissolving the corporation
A 30% shareholder in a Toronto family business is excluded from board meetings, denied financial information, and sees the majority pay themselves inflated salaries while the company declares no dividends. This pattern — even without any single illegal act — is a textbook oppression fact pattern, and can support an application for a forced buyout at fair value.
Common Scenarios in Toronto Businesses
We regularly see oppression issues arise from: being frozen out of management decisions, dilution of a shareholder's interest through a share issuance with no legitimate business purpose, diversion of corporate opportunities to a majority shareholder's other ventures, and withholding financial information a shareholder is entitled to see. Related conflicts often overlap with a straightforward breach of a shareholders' agreement, which can be pursued alongside an oppression claim.
Bringing an Oppression Application
Oppression claims proceed by application (a more streamlined process than a full action) in the Ontario Superior Court of Justice. We begin with a detailed review of your shareholders' agreement, corporate records, and the specific conduct at issue, to assess the strength of a claim and realistic outcomes — including whether a negotiated buyout can resolve the matter without a contested hearing.

Frequently Asked Questions
Conduct that is oppressive, unfairly prejudicial, or that unfairly disregards a complainant's interests. Examples include excluding a minority shareholder from decision-making, diverting corporate opportunities, paying excessive compensation to majority shareholders while withholding dividends, or diluting a shareholder's interest without a legitimate business reason.
Most commonly shareholders, but the Business Corporations Act extends standing to any "proper person," which can include directors, officers, creditors, and in some circumstances trustees in bankruptcy — provided they can show a legitimate interest affected by the conduct in question.
Courts have very broad discretion, including awarding money damages, ordering the corporation or other shareholders to buy out the complainant's shares, appointing a receiver, amending corporate governance documents, or in extreme cases ordering the corporation dissolved.
No. Oppression does not require illegal conduct — it targets conduct that is unfair given the complainant's reasonable expectations, even where the majority technically complied with the letter of corporate formalities.
Oppression claims are generally subject to Ontario's standard two-year limitation period, running from when the oppressive conduct was, or reasonably ought to have been, discovered. Ongoing oppressive conduct can affect how this is calculated, so early legal advice is important.
A forced buyout can go either way — courts sometimes order the majority to buy out a minority shareholder as a remedy, but a court could also, in principle, order other relief depending on what is fair in the circumstances. We assess the likely range of outcomes before you proceed.
Yes, significantly — the terms of any shareholders' agreement help define what a complainant's "reasonable expectations" actually were, and can either strengthen or complicate an oppression claim depending on what was agreed to in writing.
