The situation
Franco worked full-time as a grocery clerk. On weekends, he made small-batch preserves in his kitchen and sold them at a farmers' market in Cambridge. His friend Marcia, who worked as a bookkeeper, joined him after the second season, handling pricing, taxes, and the growing pile of receipts. Within two years, what had started as a hobby was doing roughly $100,000 a year in sales, split between the market stall, a handful of small grocery accounts, and online orders.
At that point they incorporated, splitting ownership evenly between themselves. To buy proper equipment and move production out of Franco's kitchen into a rented commercial space, they needed capital they didn't have. An acquaintance named Devon offered to invest $15,000 in exchange for a 20% ownership stake, with Franco and Marcia's shares reduced proportionally to 40% each. Devon wasn't involved in day-to-day operations — the investment was passive, a bet on the business growing.
The three of them agreed on the split over a coffee and a handshake. When they came to Treadstone Law, it was Marcia's idea. As a bookkeeper, she was used to seeing what happens when the financial side of a business runs ahead of its paperwork, and she didn't want three people relying on goodwill to define what happened if one of them wanted out — or if someone wanted to sell the whole thing.
Franco, for his part, was less worried. Things had gone smoothly for a year; Devon cashed his modest quarterly updates, never asked to weigh in on a supplier decision, and seemed happy simply watching the business grow. Franco's instinct was that a formal agreement was an expense for a problem they didn't have. Marcia's instinct, closer to the mark, was that the whole point of a shareholder agreement is to exist before anyone can say with confidence whether they will need it.
The legal problem
At the time they came in, the company had articles of incorporation and nothing else. No shareholder agreement existed. That meant the three owners were governed only by the default rules under Ontario's Business Corporations Act and whatever they could agree on in the moment — which works fine when everyone gets along and falls apart the moment they don't.
The specific risk our team flagged was what happens if the company is ever sold. Without a written agreement, a sale of the business usually has to happen as a sale of its shares, and every shareholder has to agree to sell their own shares — nobody can be forced to sell just because the other owners want to. That gives even a small minority shareholder outsized leverage. A buyer who wants full ownership of the company, which most buyers do, can be held hostage by one shareholder holding out for a better price, or simply refusing on principle.
Two clauses exist specifically to prevent that standoff. A drag-along right lets a majority of shareholders who agree to sell force the minority to sell too, on the same price and terms — so a buyer can be confident that a deal with the majority is a deal for the whole company. A tag-along right runs the other way: if the majority sells, a minority shareholder can insist on selling their shares on the same terms rather than being left as a minority owner under a new, unfamiliar controlling shareholder. Together, the two clauses make an eventual sale possible and make sure the terms of that sale are fair to everyone, not just whoever has the most shares.
Devon, as the 20% shareholder, had the most to lose from a deal without tag-along protection, and the most leverage to abuse without a drag-along clause pinning that leverage down. Getting the agreement signed while all three owners were still on good terms — before there was a buyer, a number, or a disagreement to fight about — was the only realistic way to get Devon to agree to terms that would eventually bind him. Once a real offer is on the table, a shareholder who stands to gain by holding out has every incentive to do exactly that, and no incentive left to sign anything that limits the leverage a delay creates.
What we did
- Reviewed the corporate structure and the informal deal. We asked Franco, Marcia and Devon separately to describe their understanding of the 40/40/20 split, the terms of Devon's $15,000 investment, and whether he had any say in daily operations. All three descriptions matched, which meant there was no underlying disagreement to resolve — only an oral arrangement that had never been written down and needed to be formalized exactly as everyone already understood it, before memories drifted or circumstances changed.
- Drafted a shareholder agreement covering the full lifecycle of ownership. Beyond the share split, the agreement set out how major decisions would be made and by what vote threshold, what happened if a shareholder died, became disabled, or wanted to leave voluntarily, restrictions on transferring shares to outsiders without the other owners' consent, and how the business would be valued when any of those triggering events occurred. Each scenario was chosen because it was a plausible way three people's paths could diverge.
- Built in drag-along and tag-along rights. Franco and Marcia, holding 80% between them, gained the right to force a full sale of the company if they agreed to one with a genuine third-party buyer; Devon, holding 20%, gained the corresponding right to insist on being included in any sale they negotiated on the same terms, rather than being left behind as a minority owner under a stranger. We explained to all three why a buyer would refuse to proceed without both protections in place.
- Set a valuation mechanism in advance. Rather than leave fair value undefined — a common source of expensive disputes later, since the phrase means nothing on its own without a method attached to it — the agreement specified that a buyout price triggered by a third-party sale would be based on the actual price a real buyer agreed to pay, and that a buyout triggered by any other event, such as a shareholder leaving voluntarily, would instead use an independent business valuation under a named, agreed methodology.
- Added a dispute resolution step. If a shareholder disagreed with a valuation figure once it was produced, the agreement required a second, independent appraisal to be commissioned before anyone could bring the disagreement to court — a mechanism designed specifically to be cheaper, faster, and less damaging to the working relationship between the owners than litigation would be if a real dispute ever arose.
The outcome
About eighteen months after the agreement was signed, a regional specialty foods distributor approached Franco and Marcia about buying the company outright, folding its products into a wider distribution network. The offer was roughly $105,000 for 100% of the shares — a fair reflection of the revenue the business had built, though not a windfall.
Franco and Marcia wanted to accept. Devon did not. He felt the offer undervalued the business's growth trajectory and, without much involvement in daily operations, was reluctant to give up a stake he saw as still appreciating. Under the old handshake arrangement, that reluctance would have been the end of the deal — the buyer wanted full ownership, and a holdout minority shareholder can sink a sale entirely.
Because the drag-along clause existed, Devon's refusal wasn't the end of the conversation, only the start of a harder one. Franco and Marcia had the right to compel the sale on the agreed terms. Rather than force it and leave three people who had built something together in a bitter dispute — and risk Devon challenging the transaction later — our team used the valuation dispute process the agreement already provided for. An independent appraisal was commissioned to confirm whether Devon's pro-rata share, roughly $21,000 based on his 20% stake, reflected fair value.
The appraisal came back close to that figure, but not exactly at it, and Devon pushed for a higher number before he would sign the required consents to close. To avoid a drawn-out dispute that risked losing the buyer altogether — distributors with acquisition budgets don't wait indefinitely — Franco and Marcia agreed to top up Devon's payout from their own proceeds, bringing his share to roughly $29,000. That left the two of them splitting the remaining $76,000, about $8,000 less than a strict 80/20 split of the sale price would have given them.
The deal closed on schedule. It was a real cost, and not the outcome Franco and Marcia had hoped for when they modelled the sale — but it was a fraction of what a collapsed deal, a lost buyer, or a court application to enforce the drag-along clause would have cost, in both money and time. The agreement did exactly what it was built to do: it kept one shareholder's reluctance from being able to veto a decision the other two were entitled to make, while giving that shareholder a real, enforceable process to push back on price rather than simply refusing to cooperate.
What you can learn from this
- A shareholder agreement is cheapest and easiest to negotiate before anyone needs it — once a buyer or a dispute is on the table, every clause becomes a bargaining chip.
- Drag-along rights protect a majority's ability to sell the whole company; tag-along rights protect a minority from being left behind. A fair agreement usually needs both, not just the one that favours whoever is negotiating it.
- Setting a valuation method in advance, before there is a real number to fight over, turns an emotional dispute into a mechanical one.
- Even a well-drafted agreement doesn't guarantee everyone gets their exact pro-rata share when a sale actually happens — it guarantees there's a process for resolving disagreement instead of a deadlock.
- Passive investors and working founders often see a business's value differently. Building a dispute resolution step into the agreement is often what keeps that disagreement out of court.
