A clause-by-clause walkthrough of what belongs in a shareholder agreement, why each part matters, and the red flags to avoid.
Who this is for + what you'll get: Founders, co-owners, and investors in an Ontario corporation who have more than one shareholder (or soon will). You'll get a clause-by-clause breakdown of a shareholder agreement, real scenarios that show why each clause exists, a decisions checklist, a red-flags list, and a FAQ — so you can have an informed conversation with your co-owners and your lawyer.

What a shareholder agreement is — and why you need one
A shareholder agreement (SHA) is a private contract among the owners of a corporation that sets the rules of the relationship: who controls what, how big decisions get made, what happens to shares when someone wants out (or dies, or gets pushed out), and how disputes get resolved. The corporation's Articles and by-laws set the legal skeleton; the SHA is where the human arrangement lives.
Here's the uncomfortable truth: the best time to sign an SHA is when everyone gets along, and the moment you'll wish you had one is when they don't. Without it, Ontario's Business Corporations Act and default corporate rules fill the gaps — and those defaults rarely match what the founders actually intended. A 50/50 company with no SHA and a falling-out is a recipe for deadlock, and possibly a court-ordered wind-up.
📦 Scenario: Two founders launch a company 50/50, no SHA. Three years in, one wants to sell to a competitor; the other refuses. There's no mechanism to break the tie and no agreed way to buy each other out. The business freezes while they fight — and lawyers, not the founders, end up shaping the outcome. A simple SHA would have set the rules in advance.
How to use this deep-dive
We go clause by clause. For each one: what it does, why it matters, and what to decide. Use the decisions checklist at the end to capture your answers, then take them to a lawyer to draft. You don't need every clause for every company — but you should consciously decide on each, rather than discover the gap during a crisis.
1. Share ownership and vesting
What it does: Records who owns what, in which class of shares, and on what terms. Vesting means founders earn their shares over time (or by hitting milestones) rather than owning them all outright on day one.
Why it matters: Vesting protects the company from the "walk-away founder" — someone who takes a big chunk of equity, leaves after a few months, and keeps it all while everyone else builds the company. With vesting, unearned shares can be bought back.
Decide: Who owns how much? Do founders' shares vest over time (e.g., over several years, often with an initial "cliff" period)? What happens to unvested shares if someone leaves?
2. The board and decision-making
What it does: Sets who sits on the board of directors, how directors are appointed, and which decisions need more than a simple majority. Voting thresholds define what passes — ordinary decisions might need a simple majority, while major ones (selling the company, issuing new shares, taking on big debt) might need a supermajority or unanimous consent.
Why it matters: This is the control map. Without agreed thresholds, a majority owner can make sweeping changes a minority owner never agreed to — or a 50/50 split can deadlock on everything.
Decide: How many board seats, and who appoints them? Which "fundamental" decisions require a higher threshold or specific consents? How are ties broken?
⚠️ Watch out for the 50/50 trap. Equal ownership feels fair but builds in deadlock. If you go 50/50, you must include a tie-breaking or buy-sell mechanism so the company can't freeze.
3. Restrictions on share transfers (right of first refusal)
What it does: Limits a shareholder's ability to sell or give away their shares to outsiders. A right of first refusal (ROFR) means that before selling to a third party, a shareholder must first offer the shares to the existing shareholders (or the company) on the same terms.
Why it matters: It stops a stranger — or a competitor — from buying their way into your ownership group without the others' agreement. You chose your co-owners; this keeps it that way.
Decide: Can shares be transferred at all, and to whom (e.g., a family trust may be allowed, an outsider not)? How does the ROFR work, and how long do the others have to match an offer?
4. Shotgun and buy-sell provisions
What it does: A buy-sell clause is a mechanism for one owner to buy out another, or to force a sale, on pre-agreed terms. The classic shotgun clause: one shareholder names a price; the other must either sell their shares at that price or buy the offeror's shares at that same price. It forces a fair number, because the person setting the price could end up on either side.
Why it matters: It's the pressure valve for an unworkable partnership. When owners can't agree to keep going, a buy-sell lets one side cleanly exit instead of the business dying in a standoff.
Decide: Do you want a shotgun, a fixed buy-out formula, or another exit mechanism? What triggers it? Are there safeguards so a cash-rich owner can't use a shotgun to squeeze out a cash-poor one?
⚠️ Shotgun clauses can favour the wealthier shareholder, who can more easily fund a buyout. Consider whether it fits your group, or whether a valuation-based buyout is fairer.
5. Drag-along and tag-along rights
What it does:
- A drag-along right lets majority owners selling the company force minority owners to sell on the same terms, so a buyer can acquire 100%.
- A tag-along (or "come-along") right lets minority owners join a sale by the majority on the same terms, so they aren't left behind holding shares in a company with a new controlling owner.
Why it matters: Drag-along makes the company sellable (buyers usually want all of it). Tag-along protects the little guy from being stranded. Together they balance the interests of majority and minority.
Decide: Will you include both? What ownership percentage can trigger a drag-along? Are the protections (same price, same terms) clearly equal for everyone?
6. The valuation method
What it does: Sets how shares get valued when they're bought or sold under the agreement — by a formula, by an independent valuator, by an agreed price updated periodically, or some combination.
Why it matters: Almost every other clause (buy-sell, departure, death, disability) eventually asks "at what price?" If the answer isn't agreed in advance, you get a second dispute on top of the first. A clear valuation method is the quiet backbone of the whole agreement.
Decide: Formula, independent valuation, or agreed price? Who pays for the valuation? How often is an agreed price refreshed?
7. Death, disability, and departure (and funding the buyout)
What it does: Spells out what happens to a shareholder's shares if they die, become disabled, retire, resign, or are terminated — typically a buyout by the company or the other shareholders at the agreed valuation. Crucially, it can be funded by insurance (life and/or disability) on each owner.
Why it matters: Without this, you could end up in business with a deceased founder's spouse or estate — people who never signed up to run a company with you. Insurance-funded buyouts mean the money to buy the shares is actually there when the event happens, instead of draining the business or forcing a fire sale.
Decide: What counts as a "good leaver" vs. "bad leaver," and does the price differ? Who must the company/owners buy out, and is it mandatory or optional? Will you put life/disability insurance in place to fund it?
📦 Scenario: A three-owner company carries life insurance on each founder, with the SHA directing that proceeds buy out a deceased founder's shares from the estate. When one founder dies unexpectedly, the estate is paid fairly, the surviving owners keep control, and the business carries on. No insurance, no funding — and that whole outcome falls apart.
8. Non-compete and non-solicit
What it does: A non-compete restricts a departing shareholder from starting or joining a competing business; a non-solicit restricts them from poaching the company's clients or employees. These run for a defined time and area.
Why it matters: They protect the value the remaining owners are paying for in a buyout. Buying out a founder is far less valuable if that founder immediately competes and takes the clients.
Decide: What scope (time, geography, activities) is reasonable? Note that Ontario courts scrutinize restrictive covenants and will not enforce ones that are broader than necessary — so they must be carefully tailored. Get these drafted by a lawyer.
Also check the employment-law limit: since 25 October 2021, Ontario's Employment Standards Act, 2000 has prohibited non-compete agreements with employees, with narrow exceptions for executives and for someone who sells a business and then works for the buyer. Founders are usually employees of their own company too, so a non-compete sitting in an employment contract can be void no matter how reasonable its scope. Ask your lawyer which document the covenant belongs in.
⚠️ Overbroad non-competes are often unenforceable. A clause that's too wide can be struck down entirely, leaving you with no protection. Narrow and specific beats sweeping and void.
9. Dispute resolution
What it does: Sets how disagreements get resolved — negotiation, then mediation, then arbitration, before anyone goes to court — and may include the deadlock-breaking mechanisms (like the shotgun) for true impasses.
Why it matters: Litigation is slow, public, and expensive. A staged dispute-resolution clause keeps fights private and faster, and gives a clear path out of a deadlock instead of leaving the company paralyzed.
Decide: What's your escalation path? Will you require mediation and/or arbitration? How are deadlocks ultimately broken?
10. Dividend policy
What it does: Sets expectations for whether and when profits are distributed to shareholders as dividends, versus reinvested in the business.
Why it matters: Owners often have different needs — one wants income now, another wants to reinvest and grow. An agreed (even if flexible) policy prevents a recurring fight every profitable year and aligns expectations up front.
Decide: Will you commit to a policy or guideline? Who decides distributions, and at what threshold?
11. Financing obligations
What it does: Addresses what happens when the company needs more money — whether shareholders are expected to contribute further capital, how new shares are issued, and what happens to an owner who can't or won't put in their share (e.g., dilution, where their ownership percentage shrinks).
Why it matters: Growth costs money. If one owner can fund a capital call and another can't, you need pre-agreed rules — otherwise the funding owner feels exploited and the non-funding owner feels squeezed.
Decide: Are shareholders obligated to fund future rounds? What happens to those who don't — dilution, loans, or something else? How are new shares priced and offered (e.g., pre-emptive rights to keep your percentage)?

Red flags — fix these before you sign
- 🚩 No agreement at all for a multi-owner company. The single biggest risk.
- 🚩 A 50/50 split with no tie-breaker or buy-sell. Built-in deadlock.
- 🚩 No valuation method. Every buyout becomes a second fight.
- 🚩 No death/disability plan or funding. You could end up in business with an estate.
- 🚩 Overbroad non-competes that won't hold up and give false comfort.
- 🚩 No transfer restrictions, letting a stranger or competitor buy in.
- 🚩 Vague "we'll figure it out later" on departures, dividends, or financing.
- 🚩 A template pulled off the internet that doesn't match your share structure or province.
Mini-FAQ
Do I really need one if I trust my co-founder? Yes — especially then. The SHA is for the future version of your relationship under stress (or after a death or disability), not today's good-faith one. Signing it while you trust each other is exactly the point.
When should we sign it? As early as possible — ideally at or shortly after incorporation, before money, customers, or disputes raise the stakes. Retrofitting one after a disagreement is much harder.
Is a shareholder agreement the same as the Articles or by-laws? No. The Articles and by-laws are the corporation's formal legal framework; the SHA is a private contract among the owners that governs their relationship and can address things the Articles don't.
Can we change it later? Yes, by agreement of the parties (usually requiring a defined level of approval set in the SHA itself). It should evolve as owners, investors, and circumstances change.
