Every day, Ontario businesses operate as partnerships without any written agreement — sometimes deliberately, sometimes because partners never got around to formalizing things. If that describes your situation, you are not operating in a vacuum. Ontario's Partnerships Act contains a detailed set of default rules that apply automatically whenever partners have not agreed otherwise in writing. These rules were drafted to be fair in the abstract. In practice, they frequently produce outcomes that surprise — and frustrate — the partners they govern.
Understanding the Partnerships Act default rules is the first step toward deciding whether to let them stand or replace them with a tailored partnership agreement.
How Default Rules Work
Think of the Partnerships Act defaults as off-the-shelf terms that slot into your partnership automatically. You can override most of them in a written partnership agreement. Where you have said nothing — or your agreement is silent on a specific point — the statute fills the gap.
The defaults do not require any filing or registration to take effect. They kick in the moment a qualifying partnership relationship exists.
The Key Default Rules You Need to Know
Equal Sharing of Profits and Losses
One of the most consequential defaults: profits and losses are shared equally among partners, regardless of how much capital each contributed or how much work each does. If Partner A invested $200,000 and Partner B invested $10,000, but there is no agreement on profit sharing, they split profits 50/50.
This equal-share rule catches many partners off guard, particularly in arrangements where contributions are clearly unequal.
No Partner Is Entitled to a Salary
Partners are not employees. Under the default rules, no partner is entitled to remuneration (salary or wages) for acting in the partnership business — even if one partner runs the entire operation while the other is mostly passive. Compensation flows through profit distributions, not salary, unless the agreement says otherwise.
This matters for tax planning as well as fairness.
Every Partner Can Participate in Management
By default, every partner has an equal right to participate in the management of the business. There is no managing partner, no senior partner with extra voting weight, no non-voting partner — unless the agreement creates those distinctions.
This default can create decision-making gridlock in a two-person partnership where the partners disagree.
Unanimous Consent for Certain Decisions
Even where partners share management equally, some decisions require unanimous consent under the default rules:
- Admitting a new partner.
- Changing the nature of the partnership business.
- Expelling a partner.
If any partner withholds consent for a new member, no new partner can be admitted. This veto is absolute in the absence of a contrary agreement.
Any Partner Can Bind the Partnership
Under the default rules, each partner is an agent of the firm. An act of any partner for carrying on in the usual way business of the kind carried on by the firm binds all partners and the partnership — even if the other partners did not authorize the act and were not aware of it.
Example: If your partner signs a supply contract in the partnership's name, you are bound by that contract even if you had no idea it was being signed. The counterparty does not need to check with you first.
This mutual agency exposure is one of the strongest arguments for a written agreement that limits each partner's authority.
Accounting Access
Every partner is entitled to inspect and copy the partnership's books, which must be kept at the place of business. This default is protective — no partner can be shut out of financial records.
No Assignment of Partnership Interest Without Consent
A partner cannot assign their full partnership rights (including the right to participate in management) to a third party without the consent of all other partners. A partner can assign their right to receive profits, but the assignee does not thereby become a partner or get any management rights.
Dissolution Defaults: The Riskiest Gap
If your partnership has no fixed term, the default rules allow any partner to dissolve the partnership at any time by giving notice to the other partners. This means one disgruntled partner can effectively end the entire business on short notice.
Even in partnerships with a fixed term or specific purpose, the law dissolves a partnership automatically upon:
- The death or bankruptcy of any partner.
- An event that makes it unlawful for the business to continue.
- A court order.
Without an agreement that includes buy-sell provisions, death-of-partner mechanisms, and notice periods, any of these events can trigger immediate dissolution and a wind-up process that is far more disruptive and expensive than it needed to be.
The Case for a Written Agreement
The default rules are not unreasonable — they represent the legislature's best guess at what equal partners in a simple business would want. But few real partnerships are that simple. Most have:
- Unequal capital contributions.
- Partners who contribute different amounts of time and skill.
- A need for one person to have final authority.
- A preference for continuity over dissolution when something goes wrong.
A written agreement replaces the defaults that do not fit your arrangement and preserves the ones that do. It is not about distrust — it is about clarity.
Frequently asked questions
Does the Partnerships Act apply if we never signed anything?
Yes. The Partnerships Act applies to every Ontario partnership that meets the statutory definition — two or more persons carrying on business in common with a view to profit. You do not need to sign anything for the Act to govern your relationship; it applies automatically.
Can we partially override the default rules?
Yes. Partners can override almost all of the default rules in their written agreement. A few provisions — mainly those protecting third parties dealing with the partnership — cannot be contracted out of by the partners alone.
What if our agreement is silent on a specific issue?
The statutory default applies to that issue, even if your agreement addresses other matters. Comprehensive drafting is important — a half-written agreement can leave dangerous gaps.
Are the Partnerships Act defaults the same for LLPs and limited partnerships?
No. The Limited Partnerships Act has its own rules governing limited partnerships, and LLPs have some modified provisions in the Partnerships Act itself. If your structure is anything other than a plain general partnership, the specific statute governing that structure applies.
