Decision-Making and Voting Rights in an Ontario Partnership

Absent a written agreement saying otherwise, Ontario’s Partnerships Act supplies a layered default framework for how partnership decisions get made. For ordinary matters connected with the usual course of the partnership’s business, the default rule generally allows a majority of partners to decide the matter, with the decision then binding on the partnership as a whole, including any dissenting partners.

For more fundamental matters — most notably, changing the essential nature of the partnership business — the default rule generally shifts to requiring unanimous consent from every partner. The idea behind this distinction is straightforward: partners should be able to run the day-to-day business efficiently without needing everyone to agree on every small decision, but no partner should be forced into a fundamentally different business than the one they originally signed up for without their agreement.

It’s worth emphasizing that these are default rules, not mandatory ones. A written partnership agreement can generally override them, setting different thresholds for different categories of decisions based on what actually suits the partners and the business. Our guide to partnership agreements in Ontario covers how decision-making provisions typically fit into a broader agreement.

The line between an “ordinary” matter decided by majority and a “fundamental” matter requiring unanimity isn’t always obvious, and this ambiguity is itself a common source of partnership disagreement. Hiring a new employee, signing a routine supplier contract, or setting day-to-day pricing would generally be considered ordinary matters falling within the usual course of business.

Larger or more unusual transactions sit in a greyer area. Taking on a significant new debt, entering a major new contract outside the partnership’s usual activities, or making a large capital expenditure could, depending on the circumstances and the size of the business, be treated as either an ordinary business decision or something closer to a fundamental change — and partners don’t always agree on which category a given decision actually falls into.

Beyond changing the fundamental nature of the business, Ontario’s default partnership rules generally also require unanimous consent to admit a new partner into the partnership. The reasoning is similar to the fundamental-change rule: existing partners have a significant interest in who else they’re doing business with, and a majority shouldn’t be able to force a new partner on a dissenting partner.

Other matters that commonly require unanimous consent, either under general partnership law principles or as a matter of common practice written into agreements, include changes to the partnership agreement itself, decisions to voluntarily dissolve the partnership, and expulsion of an existing partner, absent a specific expulsion mechanism the partners agreed to in advance.

A written agreement can expand this list considerably — for example, requiring unanimous consent for any decision above a certain dollar threshold, or for any transaction with a related party — depending on how much protection the partners want against being bound by decisions they didn’t personally agree to.

Because the Partnerships Act’s default rules are just that — defaults — partners have considerable freedom to design a voting structure that actually fits their business. A written agreement might specify different consent thresholds for different categories of decisions: a simple majority for routine operational matters, a supermajority (such as two-thirds) for moderately significant decisions, and unanimous consent reserved for genuinely fundamental changes.

Agreements can also specify who votes on what. Some partnerships separate financial decisions from operational decisions, giving different partners primary authority over each category based on their role or expertise, rather than treating every decision as something every partner votes on equally.

Whatever structure the partners choose, writing it down clearly reduces the risk of a dispute later about whether a particular decision was properly authorized — and about whether a partner who exceeded their actual authority can bind the partnership to a commitment the others never agreed to.

One of the most consequential choices in designing a partnership’s voting structure is whether each partner gets one equal vote, regardless of their capital contribution, or whether voting power is weighted according to ownership percentage or the amount each partner has invested. Neither approach is inherently right or wrong — the better fit depends on what the partners actually value.

An equal-vote structure reflects the idea that each partner’s judgment and involvement matter equally, regardless of how much capital they put in — this can suit partnerships where partners contribute differently (one in capital, one in labour or expertise) but are meant to have an equal say in running the business. A weighted structure, by contrast, reflects the idea that greater financial risk should come with greater control — often favoured where capital contributions are significantly unequal.

Some agreements blend the two approaches: equal votes for certain categories of decisions (like operational matters) and weighted votes for others (like decisions affecting capital or ownership structure). Our guide to profit and loss sharing in an Ontario partnership covers a related question — how contribution translates into economic share — that partners often work through alongside their voting structure.

Deadlock arises when partners are evenly split on a decision and no mechanism exists to break the tie — a particularly common risk in two-person partnerships, where any disagreement is automatically a 50/50 split, but also a real risk in larger partnerships with an even number of partners or factional voting blocs.

Left unaddressed, deadlock can effectively freeze the business from making an important decision, and sustained deadlock can sometimes escalate all the way to a court application to dissolve the partnership, if the partners can’t find a way forward together. This is one of the more disruptive outcomes a partnership can face, and it’s almost always more disruptive than simply planning for the possibility in advance.

Common ways partnership agreements address deadlock include designating a neutral tie-breaker for specific decisions, requiring mandatory mediation before either side can escalate further, or building in a defined buyout mechanism that triggers if a deadlock persists beyond a set period. Our guide to common partnership disputes in Ontario and our broader Partnerships hub cover related issues that often surface once a deadlock turns into an active dispute.

Beyond deciding how votes are counted, it’s worth thinking about how partnership decisions actually get documented as the business grows. In a very small, informal partnership, major decisions are sometimes made in conversation without any written record, which can work fine while the relationship remains amicable — but becomes a real problem if a dispute later arises about what was actually decided, and by whom.

Keeping a simple written record of significant decisions — even an informal log of what was decided, when, and by which partners — can meaningfully reduce the risk of a later dispute about whether a decision was properly authorized under the partnership’s voting rules. This becomes increasingly important as a partnership grows, takes on more partners, or starts making decisions with more significant financial consequences.

For a partnership that started informally and is only now putting formal decision-making rules in writing, it’s not too late to do so. Partners can adopt a voting framework at any point, reflecting how the business has actually been run while filling in gaps — like what happens on deadlock — that the original, informal understanding never addressed. Our guide to partnership agreements in Ontario covers how to approach formalizing an existing partnership’s terms more broadly.
