Common types of shareholder disputes
Oppression
The oppression remedy under section 248 of the Ontario Business Corporations Act is the most powerful tool available to shareholders. It applies when a corporation's conduct is oppressive, unfairly prejudicial, or unfairly disregards a shareholder's interests, measured against what they reasonably expected.
Common examples include majority shareholders diverting corporate opportunities, paying themselves excessive compensation, refusing to declare dividends, diluting minority shareholdings, or excluding shareholders from management.
Deadlock
Deadlock arises when shareholders with equal voting power can't agree on fundamental business decisions: hiring, firing, major expenditures, or strategic direction. Without a shareholders' agreement containing a deadlock resolution mechanism, the business can be paralyzed.
Breach of fiduciary duty
Directors and officers owe fiduciary duties to the corporation, including duties of loyalty, honesty, and good faith. When a director-shareholder breaches these duties by self-dealing, competing with the corporation, or diverting corporate opportunities, the other shareholders can pursue remedies.
Breach of the shareholders' agreement
When a shareholder violates the terms of the shareholders' agreement, by transferring shares without consent, competing with the business, or ignoring buy-sell provisions, the other shareholders can sue for breach of contract and seek enforcement. A plain money claim of $50,000 or less can go to Small Claims Court. Larger claims belong in the Ontario Superior Court of Justice, which Jonathan doesn't handle.
Forced buyouts and exits
When the relationship has broken down beyond repair, one owner leaving is often the only real resolution. Whether that happens by agreement or by court order, the fight usually comes down to price.
Why shareholder disputes start
The bitterest shareholder disputes I see aren't between strangers. They're between siblings, parents and children, and old friends: people who went into business together because they trusted each other. That trust is usually why they never signed a shareholders' agreement, and it's why they needed one more than anyone.
What they end up fighting about is almost never the thing in the demand letter. It's an expectation one side held and never said out loud: that a brother who worked fewer hours would draw less, that profits would be paid out instead of reinvested, or that a founder could walk away and keep their shares. Most disputes are misaligned expectations that finally surfaced.
How a negotiated buyout works, step by step
Most shareholder disputes that resolve well end the same way: one side buys the other out on terms both can live with. This is the path Jonathan follows to get there without a court application.
Read what you signed
The shareholders' agreement, articles and by-laws may already decide the outcome: a buy-sell or shotgun clause, a right of first refusal, a valuation formula, or a clause sending disputes to mediation or arbitration.
Don't escalate on your own
Locking a partner out of the bank account or the books, cutting their pay without proper authority, or moving customers to a new company can hand the other side an oppression complaint and cost you leverage.
Put it in writing
A demand letter, or a measured response to one, sets out the problem, what you want, and what you're prepared to do. It's often the first time both sides see the dispute in the same terms.
Agree on value
Most buyouts turn on price. One independent valuation, often from a Chartered Business Valuator retained jointly, costs less than two competing reports and narrows the fight.
Negotiate, then mediate
Terms matter as much as price: payment schedule, security for any unpaid balance, guarantees, releases and restrictive covenants. If talks stall, a mediator can often close the gap in a single session.
Close it properly
A share purchase agreement, mutual releases, resignations, an updated minute book, and a notice of change filed with the Ontario Business Registry within 15 days of a director or officer change.

The oppression remedy: leverage before litigation
A "complainant" under the Business Corporations Act includes a current or former shareholder, a current or former director or officer, and anyone else the court decides is a proper person to apply. If the court finds oppression, it can make almost any order it thinks fit, including:
- A buyout order directing the corporation or another shareholder to purchase your shares
- Restraining orders stopping the conduct complained of
- Compensation for the person harmed
- Setting aside a transaction that was unfair to you
- Appointing a receiver, replacing directors, or amending the articles
- Winding up the corporation, in the most serious cases
Those orders come from the Superior Court of Justice. Jonathan doesn't take Superior Court matters, so if your dispute needs an application, he refers you to trusted litigation counsel. Many disputes never get that far. An oppression complaint that's well documented and clearly set out in a demand letter is often what brings the other side to the table. Don't sit on it, though. Delay can weaken a claim, and limitation periods may apply.

FAQs.
Common questions about shareholder disputes in Ontario.
What is an oppression remedy?
An oppression remedy is a statutory claim under section 248 of Ontario's Business Corporations Act. It lets a complainant, usually a shareholder, director or officer, ask the court to fix corporate conduct that is oppressive, unfairly prejudicial, or unfairly disregards their interests. It's the most common remedy in shareholder disputes, and the application is heard in the Superior Court of Justice.
Can a minority shareholder sue a majority shareholder?
Yes. A minority shareholder can bring an oppression application, a derivative action on the corporation's behalf, or a claim for breach of a shareholders' agreement. Many of these disputes settle before anything is filed, often through a negotiated buyout.
What if we never signed a shareholders' agreement?
Then there's no buy-sell, shotgun or deadlock clause to fall back on. The Business Corporations Act and your articles set the default rules, and an owner generally can't be forced to sell without agreeing to it or a court ordering it. Most of these disputes end in a negotiated buyout. If talks fail, the usual next step is an oppression application in the Superior Court.
What is shareholder deadlock?
Deadlock happens when shareholders with equal voting power can't agree on major decisions, and the corporation stalls. A shareholders' agreement with a deadlock mechanism prevents it. Without one, the options are negotiation, mediation, or an application to the court.
Can I force a shareholder to sell their shares?
Only through a mechanism that allows it: a shotgun clause, drag-along or other buy-sell term in the shareholders' agreement, or a court order on an oppression application. Without one of those, you can't make a shareholder sell, but you can usually negotiate a buyout.
Do I have to pay for a buyout all at once?
No. A buyout can be paid over time through instalments or a vendor take-back, usually with security for the unpaid balance and releases on both sides. The right structure depends on the company's cash flow and how much risk the departing shareholder will accept.
How much does a shareholder dispute lawyer cost?
It depends on how complex the dispute is and how far it goes. Jonathan offers a free 30-minute consultation to assess the situation and discuss fees before any work begins. He doesn't take Superior Court matters, so oppression applications and other Superior Court proceedings are referred to trusted litigation counsel.
