A partnership agreement contract is a written contract between two or more people or companies carrying on a business together that sets out capital contributions, profit and loss sharing, decision making authority, and what happens when a partner leaves, dies or the partners disagree. Ontario law does not require a written agreement to form a partnership, but without one the Partnerships Act imposes default rules on your business, including equal profit sharing and the right of any partner to dissolve the partnership on simple notice. This guide explains the essential terms every Ontario partnership agreement should contain, the registration steps and government fees, and the mistakes we help clients avoid.
What Is a Partnership Agreement Contract?
A partnership agreement contract, often simply called a partnership agreement, is the governing document of a partnership. It records what each partner puts in, what each partner takes out, who decides what, and how a partner exits. Once signed, it replaces most of the default rules that Ontario law would otherwise impose on your business.
Under section 2 of the Ontario Partnerships Act, a partnership is the relation between persons carrying on a business in common with a view to profit. Notice what is missing from that definition. There is no signing requirement, no registration requirement and no minimum paperwork. Two people who start selling a product together and share the profits may already be partners in the eyes of the law, whether they intended it or not.
The Act repeatedly uses the phrase subject to any agreement express or implied between the partners. That phrase is your opening. Almost every internal rule in the statute can be replaced by the terms you and your partners actually choose, and the partnership agreement contract is where you record those choices.
A partnership is also not the same thing as a joint venture, which is usually a contractual collaboration for a single defined project rather than an ongoing business. If you are collaborating on one project only, read our guide on joint ventures in Ontario before assuming you need a partnership.
Do You Need a Written Partnership Agreement in Ontario?
No statute forces general partners to sign a written agreement. A general partnership can exist on a handshake, and Ontario law recognizes verbal and even implied partnership agreements. The practical answer is different. Operating a partnership without a written agreement means running your business under statutory rules you never read and never chose.
There is one important exception. A limited liability partnership cannot exist on a handshake. Under the Partnerships Act, an Ontario LLP is formed only when the partners enter into a written agreement that designates the partnership as a limited liability partnership and states that the Act governs the agreement. If you and your professional partners intend to practise through an LLP, the written agreement is a formation requirement, not a nicety. Our guide to the limited liability partnership covers that structure in detail.
Lenders, landlords and investors also expect to see a written agreement. Banks routinely ask for one before opening a partnership account or advancing credit, because the document tells them who has authority to bind the firm.
What Happens Without a Partnership Agreement?
If you never sign an agreement, the Partnerships Act fills every gap with default rules on how partners share profits, make decisions and deal with each other. Some of those defaults will surprise you. The table below sets out the ones that matter most in practice.
| Issue | Default rule under the Partnerships Act | What your agreement can do |
|---|---|---|
| Profit and loss sharing | All partners share capital and profits equally and contribute equally to losses, regardless of who invested or worked more | Set percentages that reflect actual contributions and adjust them over time |
| Pay for work | No partner is entitled to a salary or other pay for working in the business | Provide salaries, draws or bonuses for working partners |
| Management | Every partner may take part in managing the business | Assign defined roles and create a managing partner position |
| Decisions | Ordinary matters pass by majority, but the nature of the business cannot change without the consent of all partners | Set voting thresholds that match the stakes of each decision |
| New partners | No person may be introduced as a partner without the consent of all existing partners | Create an admission process with defined criteria and buy in terms |
| A partner leaving | Where no fixed term has been agreed, any partner may dissolve the entire partnership by giving notice to the others | Allow a partner to retire or withdraw while the business continues |
| Death or insolvency | The partnership is dissolved by the death or insolvency of any partner | Keep the business alive and give the estate a defined buyout instead |
One rule cannot be contracted away as against outsiders. Under section 10 of the Act, every partner is liable jointly with the other partners for all debts and obligations of the firm incurred while that person is a partner. Your agreement can require one partner to indemnify another, and that indemnity matters between you, but a creditor can still pursue any partner personally for the full debt. This is the core risk of a general partnership and one of the main reasons clients compare it with incorporating.
So what do you do with this. Treat the table above as a checklist. Every row where the default rule does not match your intentions is a clause your partnership agreement needs.

What Are the Essential Terms of a Partnership Agreement?
A strong Ontario partnership agreement runs well past the ten clauses of a generic template. These are the terms we treat as essential in our practice.
Business Name, Purpose and Term
State the firm name exactly as registered, describe the business the partnership will carry on, and say whether the partnership runs for a fixed term, until a project completes or indefinitely. The term clause matters more than most people expect, because a partnership with no fixed term is a partnership at will that any partner can dissolve on notice.
Capital Contributions and Future Funding
Record what each partner contributes at the start, whether cash, equipment, intellectual property or a book of clients, and assign a dollar value to contributions that are not cash. Then answer the harder question. What happens when the business needs more money later. Decide whether partners must contribute in proportion to their shares, whether loans from partners carry interest, and what happens to a partner who cannot or will not fund a capital call.
Profit and Loss Sharing
Set out each partner’s share of profits and losses, when distributions happen, and how much profit stays in the business as working capital. Profit shares do not have to match capital contributions. A partner who works in the business full time can earn a larger share than a partner who only invested money, but only if the agreement says so.
Roles, Responsibilities and Time Commitment
Describe who runs what. Assign responsibility for operations, finances, sales and hiring, and state the time commitment expected from each partner. When one partner drifts to part time effort on a full share of profits, this clause is what the other partners rely on.
Decision Making, Voting and Deadlock
Match the voting rule to the stakes. Routine operational choices can sit with the responsible partner, ordinary business decisions can pass by majority, and fundamental changes such as borrowing above a threshold, admitting a partner or selling major assets should need unanimity or a supermajority. In a two partner firm with equal votes, add a deadlock mechanism such as mediation followed by a structured buyout, because two reasonable people can still disagree forever.
Banking, Books and Financial Reporting
Name the financial institution, state who can sign on the account and at what dollar limits, and require proper books. The Act already gives every partner the right to inspect the partnership books, and your agreement should build on that right with regular financial reporting to all partners.
Admission of New Partners
Set the process for bringing in a new partner, including who must approve the admission, how the buy in price is calculated, and whether the new partner signs the existing agreement or a restated one.
Withdrawal, Retirement and Expulsion
Give partners a lawful way out that does not destroy the business. Set a notice period for voluntary withdrawal, define retirement terms, and decide whether the remaining partners can expel a partner for defined causes such as fraud, professional misconduct or extended absence. Under the Act, no majority of partners can expel a partner unless the power to do so was conferred by express agreement, so if you skip this clause the power simply does not exist.
Buyout Terms and Valuation
The buyout clause is the single most valuable clause in the document. Decide how a departing partner’s interest is valued, whether by an agreed formula, an independent business valuator or a multiple of earnings, and how the price is paid, whether in a lump sum or in instalments over a defined period. Without an agreed method, valuation becomes the battlefield of every partnership breakup.
Death, Incapacity and Insurance
Under the default rules, the death or insolvency of a partner dissolves the partnership. Most partners want the opposite, a business that continues while the deceased partner’s estate receives fair value. Address death and incapacity directly, and consider life insurance on each partner so the surviving partners can fund the buyout without borrowing. This clause should line up with each partner’s will, and our guide to business succession planning explains how the pieces fit together.
Dispute Resolution
Decide in advance how disagreements get resolved. A staged clause that requires direct negotiation first, then mediation, then arbitration keeps most disputes out of court and keeps the firm’s finances private. Litigation between partners is slow, public and expensive, and it usually ends the partnership either way.
Restrictions on Competing and Confidentiality
The Act already requires a partner who carries on a competing business without the consent of the other partners to account for the profits of that competing business. Your agreement should go further, with confidentiality obligations and reasonable restrictions on soliciting the firm’s clients and staff after a partner leaves. Keep the restrictions modest in scope and duration, because Ontario courts will not enforce restraints that go further than needed to protect the business.
Dissolution and Winding Up
Even the best partnership eventually ends. State the events that trigger dissolution, who winds up the business, the order in which debts and capital are repaid, and what happens to the firm name and client relationships. The Act supplies a default payment order on dissolution, but you can and usually should tailor it to your situation.
What Types of Partnerships Can You Form in Ontario?
Ontario recognizes three partnership forms, and the right agreement depends on which one you are in. If you are still deciding between a partnership, a sole proprietorship and a corporation, start with our overview of business structures in Ontario.
| Feature | General partnership | Limited partnership | Limited liability partnership |
|---|---|---|---|
| Governing statute | Partnerships Act | Limited Partnerships Act | Partnerships Act, LLP provisions |
| Personal liability | Each partner is jointly liable for all firm debts | General partners are fully liable, limited partners risk only their contribution | Partners are shielded from liability for another partner’s negligence but remain liable for their own |
| Who can use it | Any two or more persons carrying on business for profit | Any business, common for investment and real estate ventures | Only professions whose governing statute permits LLPs, such as lawyers and accountants |
| Formation paperwork | None required by statute, though a written agreement is strongly recommended | Declaration filed under the Limited Partnerships Act | Written agreement designating the LLP, plus firm name registration |
| Management | All partners may take part in management | A limited partner who takes part in control of the business risks losing limited liability | Partners manage as in a general partnership |
Each form still needs a partnership agreement. In a limited partnership the agreement also governs the relationship between the general partner and the limited partners under the Limited Partnerships Act, and in an LLP the written agreement is a formation requirement.
How Do You Register a Partnership in Ontario?
Registering the partnership and signing the partnership agreement are two different steps, and you need both. Registration puts the firm name on the public record. The agreement governs how the partners deal with each other.
- Choose and search your firm name. Search the Ontario Business Registry to confirm the name is available and not confusingly similar to an existing registered name.
- Register the firm name. A general partnership operating under a firm name registers under the Business Names Act through the Ontario Business Registry. The government fee to register a general partnership firm name online is $60.
- Receive your Business Identification Number. ServiceOntario issues a nine digit BIN that you will use to open provincial tax accounts and deal with the government.
- File a declaration if you are forming a limited partnership. A limited partnership is formed by filing a declaration under the Limited Partnerships Act.
- Renew every five years. A business name registration expires after five years and must be renewed, and you must update the registration when partners or addresses change.
Government fees and filing procedures change over time. The figures above are current as of the publication date of this article, and you should confirm them on ontario.ca before filing.
Depending on your revenue and activities, you may also need a CRA business number, HST registration and municipal licences. We walk clients through these requirements as part of the engagement.
What Are the Benefits of a Partnership Agreement Contract?
The benefits of a written partnership agreement show up on the worst day of the partnership, not the best one.
- Certainty. Every partner knows their share, their role and their exit before serious money is on the table.
- Dispute prevention. Most partnership litigation starts with a question the agreement could have answered in one sentence.
- Business continuity. The firm survives a death, retirement or withdrawal instead of dissolving by default.
- Protection for unequal contributions. The partner who funds more or works more is protected on paper, not just in memory.
- Credibility with banks and investors. Lenders and landlords take a documented partnership more seriously.
- A fair exit at a known price. The buyout clause turns a departure into a process instead of a fight.
There is also a quieter benefit. The drafting process itself forces partners to discuss the questions they have been avoiding, and it is far cheaper to discover a fundamental disagreement before you sign a lease than after.
What Mistakes Do Ontario Partners Make Most Often?
In our practice, the same handful of mistakes accounts for most of the partnership disputes that reach our desks.
Operating first and papering later. Partners open the bank account, sign the lease and start earning, planning to document the deal once things settle. By the time a disagreement surfaces, the leverage has shifted and one partner no longer wants to sign anything.
Copying a template from another jurisdiction. Templates drafted for other provinces or American states reference statutes that do not apply in Ontario and miss the defaults of the Ontario Partnerships Act entirely. A template that does not deal with the notice dissolution rule leaves the biggest risk on the table.
Splitting profits equally while contributions are unequal. An equal split feels fair on day one. It stops feeling fair the first month one partner works sixty hours while the other works six, and under the default rules the working partner is entitled to no salary and no larger share.
Leaving out a valuation method. A buyout clause that promises fair value with no formula and no appointed valuator invites a fight over what fair means. Name the method and the decision maker.
Ignoring death and incapacity. Younger partners skip this clause constantly. The default rule dissolves the firm on a partner’s death, and the surviving partner ends up negotiating with a grieving estate over an unwritten deal.
No deadlock clause in an equal partnership. Two partners with equal votes and no way to break a tie can paralyze a healthy business. Build the escape route before you need it.
Partnership Agreement or Shareholder Agreement?
The two documents solve the same human problems in different legal structures. A partnership agreement governs partners who own a business directly and carry personal liability for its debts. A shareholder agreement governs the shareholders of a corporation, which is a separate legal person that carries its own liabilities.
If personal liability is the concern driving your questions, the answer may not be a better partnership agreement. It may be incorporation, with a shareholder agreement playing the role the partnership agreement plays here. In the free consultation we regularly help clients settle the structure question before any drafting starts.
Frequently Asked Questions
Is a partnership agreement legally required in Ontario?
No. A general partnership exists as soon as two or more people carry on business together with a view to profit, whether or not anything is signed. The Partnerships Act then fills every gap with default rules. A written agreement is the only way to replace those defaults with terms you actually chose, and banks, landlords and investors will often ask to see one.
Can a partnership agreement be verbal in Ontario?
Yes, Ontario law recognizes verbal and even implied partnership agreements. The problem is proof. When partners disagree, each person remembers the conversation differently, and a court may fall back on the statutory defaults. A verbal deal also cannot satisfy the written agreement requirement for a limited liability partnership.
How much does a lawyer charge for a partnership agreement in Ontario?
Cost depends on the number of partners, the complexity of contributions and buyout terms, and whether the structure is a general partnership, limited partnership or LLP. Insight Law quotes a transparent fixed fee before work begins. A free 15 minute call with our lawyer is the fastest way to get an exact quote for your situation.
Can we change our partnership agreement after signing it?
Yes. Partners can amend the agreement by unanimous written consent, or by whatever amendment threshold the agreement itself sets. The Partnerships Act also recognizes that partners can vary their mutual rights by consent, which may even be inferred from a course of dealing. Best practice is a signed written amendment so the record stays clean.
What happens if my business partner wants to leave and we have nothing in writing?
In a partnership with no fixed term, any partner can dissolve the entire partnership simply by giving notice to the others. That can force the winding up of a profitable business. Without a buyout clause there is no agreed price or payment schedule, and disputes over valuation often end up in court.
Does registering a business name create a partnership agreement?
No. Registering your firm name under the Business Names Act records the name and the partners in the Ontario Business Registry so the public can identify who stands behind the business. It says nothing about profit sharing, decision making or exits. You still need a separate partnership agreement to govern those terms.
