Do I need a shareholders’ agreement?
Yes, if your corporation has, or is about to have, more than one shareholder. A shareholders’ agreement sets out how decisions get made, how dividends are declared, and what happens if a shareholder dies, becomes disabled, divorces, or simply wants out. Without one, those questions default to whatever the Ontario Business Corporations Act and your by-laws happen to say. That is rarely what either shareholder actually wants when a real dispute arrives. A single shareholder running their own corporation has no one to disagree with yet, so the need becomes real the moment a second shareholder is added, not before.

What a shareholders' agreement actually covers
A shareholders' agreement is a private contract between the shareholders. It sits alongside, and often overrides, the default rules in a corporation's by-laws. It typically sets decision-making thresholds, spelling out which decisions need a simple majority and which need unanimous consent. It also sets a dividend policy describing how and when profit gets distributed. And it restricts transferring shares to an outsider without the other shareholders' agreement. Many are structured as a unanimous shareholder agreement under the Ontario Business Corporations Act. That structure can go further than an ordinary agreement, actually restricting the directors' powers and handing specific decisions directly to the shareholders instead.
A well-drafted agreement also addresses ordinary deadlock: what happens if two equal 50-50 shareholders simply cannot agree on a decision the by-laws require a majority for. Left unaddressed, a genuine 50-50 split can freeze a corporation entirely, unable to pass even routine resolutions, until one side gives in or the relationship breaks down completely. Agreements between equal shareholders often include a specific deadlock-breaking mechanism for exactly this reason, rather than assuming two reasonable people will always find a way to agree.
Why the buy-sell provisions matter most
The section that ends up mattering most in practice is the buy-sell mechanism. It covers what happens if a shareholder dies, becomes permanently disabled, goes through a divorce that could put shares at risk, or simply wants to leave the business. Without this spelled out in advance, a shareholder's estate, spouse, or former spouse can end up as an unwilling business partner. The remaining shareholders would then have no clear right to buy them out, or clear formula for what the shares are worth. A well-drafted agreement fixes a valuation formula in advance, so the price is not renegotiated from scratch under the worst possible circumstances.
The shotgun clause and other exit mechanisms
A common buy-sell tool is the shotgun clause. Either shareholder can offer to buy out the other at a price they set. The other shareholder must then either accept that price and sell, or turn around and buy the first shareholder out at the identical price. This forces whoever names the price to price the shares fairly, since naming a low price risks being forced to sell at that same low price themselves. Agreements often pair this with drag-along and tag-along rights. Drag-along rights protect a majority shareholder's ability to sell the whole company. Tag-along rights protect a minority shareholder's right to be included if the majority sells.
Vesting, non-competes, and departing shareholders
Shares are sometimes issued partly for future work rather than cash up front. When that happens, a vesting schedule is often tied to the shareholder staying involved for a set period. That protects the other shareholders if the person leaves early, having earned only part of their stake. A non-compete clause addresses what a departing shareholder can and cannot do afterward, particularly if they are walking away with client relationships or know-how the business depends on. Both provisions are easiest to negotiate while everyone is still on good terms. In practice, that means at the time shares are issued, not after someone has already decided to leave.
What happens without one is not "nothing"
A corporation with more than one shareholder and no agreement is not operating in a vacuum. The Ontario Business Corporations Act and the corporation's by-laws still govern how decisions get made and how disputes get resolved. They just aren't tailored to your specific business or shareholders. A dissatisfied minority shareholder can, in some circumstances, apply to the court for relief under the Act's oppression remedy. That route is slower, more public, and more expensive than resolving the same disagreement through terms the shareholders chose for themselves in advance.
Funding a buyout with insurance
A buy-sell provision triggered by death is only useful if the remaining shareholders can actually afford to buy out the deceased shareholder's estate. That is why many agreements are funded with life insurance, owned by the corporation or the other shareholders, on each shareholder's life. The insurance proceeds provide the cash to complete the buyout without forcing a fire sale of business assets or leaving the surviving shareholders in debt to the estate. This funding piece is worth setting up at the same time as the agreement itself rather than treated as a separate, optional add-on.
Weighing the cost against the alternative
A properly drafted shareholders' agreement has a real upfront legal cost, which is the most common reason smaller businesses put it off. That cost is consistently smaller than the cost of an actual shareholder dispute settled without one. There, the outcome is decided by litigation, general corporate law defaults, and legal fees on both sides, instead of terms the shareholders agreed to calmly in advance. Owners who have been through a partnership dispute without an agreement in place rarely need convincing on this point twice.
The cost also tends to scale reasonably with the size and complexity of the shareholder group. A straightforward agreement between two founders with equal shares and no unusual arrangements is generally quicker and less expensive to draft. That compares with one covering several shareholders with different share classes, vesting schedules, and family involvement. So the cost of getting this right early is rarely as large as owners initially assume, before asking for a quote.

Can I use a generic template for a shareholders’ agreement?
A template can be a starting point, but the valuation formula, dividend policy, and buy-sell terms should reflect your specific business and shareholders. We would always have a lawyer review and customize it, rather than sign a template as-is.
What happens if we do not have a shareholders’ agreement and a dispute happens anyway?
The Ontario Business Corporations Act and your by-laws still apply by default, but they were not written for your specific situation. Outcomes then tend to be decided by litigation and general corporate law, rather than terms you would have chosen in advance.
Do two co-founders who trust each other completely still need one?
Yes. The agreement is not about distrust — it is about having clear answers ready if circumstances change, such as death, disability, or one founder wanting to leave. Those things happen even in genuinely good partnerships.
