A plain-language guide to the Unanimous Shareholder Agreement — and why it might be the most important document your company ever signs.
You’ve done the hard part. You built something. You incorporated, you found a partner you trust, and you’re doing real business. Life is good.
But let me ask you a few questions.
What happens if your business partner dies? What if they go through a divorce — and suddenly their ex-spouse owns half your company? What if you and your partner disagree on a major decision and nobody can break the tie? What if one partner wants to sell and the other doesn’t?
These aren’t remote possibilities. They happen to Alberta businesses every year. And for most of them, when the moment of crisis arrives, there’s no plan in place.
That’s what a Unanimous Shareholder Agreement is for.
What Is a Unanimous Shareholder Agreement?
A Unanimous Shareholder Agreement — commonly called a “USA” — is a legally binding contract signed by all of the shareholders of a corporation. Under the Business Corporations Act, RSA 2000, c B-9 (the “ABCA”), s. 146, a USA can do something ordinary contracts cannot: it can actually restrict or transfer the powers of the directors of the company to the shareholders themselves.
That’s a significant legal tool. It means the people who own the company can agree in writing on how decisions get made, what happens to shares when life changes, and how disputes get resolved — and those rules have real legal force.
It’s not a partnership agreement (which governs partnerships, not corporations). It’s not your articles of incorporation. It’s a separate, private document that sits alongside your corporate structure and governs the relationship between the people who own shares.
Who Needs One?
The short answer: any Alberta corporation with more than one shareholder.
The longer answer includes you if any of these apply:
- You co-own a business with a spouse, sibling, friend, or colleague
- You’re bringing in a business partner or investor
- You’re planning to transition ownership to family or employees over time
- You want to protect the business from what happens in your shareholders’ personal lives
Even sole shareholders can benefit in some situations (particularly where shares may be issued in the future), but the USA is most critical the moment a second person owns shares in your company.
What Does a USA Actually Cover?
A well-drafted USA is a comprehensive document. Here are the core areas it typically addresses:
1. Share Transfers — Who Can Own Your Company?
This is the big one. Without a USA, a shareholder can generally transfer their shares to anyone they want — including someone you’ve never met, don’t trust, and would never choose as a business partner.
A USA puts a fence around that. Common mechanisms include:
Right of First Refusal: Before selling shares to an outsider, a shareholder must first offer them to the other shareholders at the same price. Your partner can’t bring in a stranger without giving you the first chance to buy them out.
Shotgun Clause: A structured buyout mechanism where one partner names a price per share and the other partner must either buy at that price or sell at that price. It sounds aggressive, but it’s one of the fairest dispute-resolution tools in business law — it forces the party naming the price to be honest, because they don’t know which side of the transaction they’ll end up on.
Drag-Along and Tag-Along Rights: If a majority shareholder finds a buyer for the whole company, drag-along forces minority shareholders to sell on the same terms. Tag-along protects minority shareholders — if the majority sells, you can insist on coming along and selling your shares too.
2. Death, Disability, and Divorce
These are the scenarios most business owners don’t want to think about. But they’re exactly what a USA is designed for.
Death: Without a USA, a deceased shareholder’s shares pass to their estate and ultimately to their heirs. That might mean your spouse is fine — or it might mean you’re suddenly in business with someone’s adult child who has no interest in the company and just wants cash. A USA can require the estate to sell shares back to the company or surviving shareholders at a defined or formula-based price.
Disability: What happens if a shareholder can no longer work due to illness or injury? A USA can define what triggers a buyout, at what price, and on what timeline — ideally coordinated with disability insurance coverage.
Divorce: A shareholder’s marriage breakdown can directly threaten your business. Under Alberta matrimonial property legislation, a spouse may have a claim to their partner’s shares. A USA can restrict the transfer of shares to non-shareholders (including former spouses) and require a buyout instead.
3. Decision-Making
Who has the authority to make what decisions? A USA can specify that certain actions require unanimous consent — things like:
- Taking on significant debt
- Signing major contracts
- Hiring or firing senior employees
- Paying dividends
- Changing the direction of the business
This protects minority shareholders from being steamrolled, and protects the business from one shareholder acting unilaterally on something that should require everyone’s agreement.
4. Salaries and Dividends
How will shareholders be compensated? This is a common source of conflict — especially where one shareholder is working in the business full-time and another is a passive investor. A USA can set out compensation structures, dividend policies, and expense rules so there’s no ambiguity.
5. Non-Compete and Confidentiality
A USA can include restrictions on shareholders competing with the company or poaching clients or employees if they leave. Depending on how it’s drafted, this can be more enforceable than a standalone non-compete.
The Fears I Hear From Business Owners
Let me speak directly to some of the hesitation I encounter in my practice.
“We trust each other. We don’t need a contract.”
I understand. And I believe you. But a USA isn’t a statement of distrust — it’s the opposite. It’s two people who respect each other enough to have a hard conversation now, while everything is good, rather than leaving ambiguity that can fester into conflict later. The couples who never talk about money aren’t the ones with the strongest marriages.
“It seems really expensive for something we might never need.”
Consider the alternative. A shareholder dispute without a USA in place can become protracted, expensive litigation — or a deadlocked company that simply cannot function. A well-drafted USA is a fraction of the cost of a single shareholder dispute. Think of it as insurance you actually understand.
“We’re just starting out. Can’t we do this later?”
This is the one that keeps me up at night. The time to sign a USA is before there’s a problem. Once a dispute arises, negotiating the terms of an agreement becomes nearly impossible — every clause becomes a battleground. And some triggering events (like a death or divorce) leave no time to negotiate at all.
“Our accountant said we don’t need one.”
We love accountants! But, a USA is a legal document that intersects with corporate law, estate planning, family property law, and sometimes securities law. It requires legal drafting tailored to your specific situation. Your accountant can give invaluable input on the financial and tax mechanics — but the document itself needs a lawyer.
An Important Legal Note
Under s. 146(1) of the ABCA, a USA binds all existing and future shareholders of the corporation. That means if someone new buys into the company, they’re bound by the agreement — but they also need to be notified that it exists. The certificate representing their shares must be noted accordingly (s. 146(3) ABCA). This is one of several technical requirements that makes proper legal drafting essential.
A USA that is poorly drafted, incomplete, or inconsistent with the ABCA can create more problems than it solves.
What Happens Without One?
Let me be direct: if your corporation has more than one shareholder and no USA, you are operating on trust alone. Trust is important — but trust is not a legal mechanism for resolving a buyout, handling a death, breaking a deadlock, or protecting your company from a shareholder’s divorce.
The ABCA provides a legal framework for corporations, but it is largely a default regime. It does not automatically give you a right of first refusal, a buyout formula, or a dispute resolution process. Those are provisions you have to build — and a USA is how you build them.
How We Can Help

Then we build an agreement that addresses them — in plain language you can actually understand.
If you’re co-owning an Alberta corporation and you don’t have a USA in place, I’d encourage you to reach out. The conversation costs you nothing. The absence of a plan could cost you a great deal more.
