Starting a business with someone you trust can feel like you do not need a formal document — but that instinct is one of the most expensive mistakes partners make. In Ontario, a partnership agreement is the contract that governs how your business runs, how profits are split, and what happens when things go wrong. Without one, Ontario's Partnerships Act fills in the gaps with default rules that almost certainly do not reflect what you actually intended.

This article walks through the key provisions every Ontario partnership agreement should address — so that when you sit down with a lawyer to draft or review one, you know exactly what questions to ask and why each clause matters.

Why the Default Rules Are Rarely What You Want

Ontario's Partnerships Act contains default provisions that apply whenever partners have not agreed otherwise. These defaults are designed for a generic scenario, not yours. A few examples that surprise many partners:

These defaults are not wrong — they are just generic. Your agreement replaces them with rules tailored to your actual deal.

Core Provisions Every Agreement Needs

1. Identity and Capital Contributions

Name the partners, describe what each is contributing (cash, property, intellectual property, sweat equity), and set out how contributions are valued. Capital accounts track each partner's stake over time. This section becomes critical during buyouts or dissolution.

2. Profit and Loss Sharing

Specify the exact ratio — 50/50, 60/40, or something more complex that accounts for different capital contributions or roles. Also clarify:

3. Decision-Making and Voting

Define which decisions require unanimous consent versus a simple majority versus just one managing partner. Common categories:

4. Duties of Partners

Set out each partner's time commitment and responsibilities. Can partners engage in outside businesses or compete with the partnership? A non-compete or non-solicitation clause during and after the partnership term protects the business and prevents a departing partner from immediately poaching clients.

5. Partner Accounts and Banking

Describe how the partnership bank account operates, who has signing authority, and what limits apply to individual partners' spending.

Dealing With Partner Changes

Admitting New Partners

The agreement should state the process and criteria: Who decides? What must a new partner contribute? Does their admission require unanimous consent? What interest do they receive?

Voluntary Withdrawal

A partner who wants to leave should give written notice within a defined period (e.g., 90 days). The agreement should specify how the withdrawing partner's interest is valued, how it is paid out (lump sum vs. instalments), and whether remaining partners have a right of first refusal on the departing partner's interest.

Death, Disability, or Bankruptcy of a Partner

Without a buy-sell mechanism, the death of a partner can trigger dissolution and significant disruption. A well-drafted agreement includes:

Expulsion of a Partner

Can partners be removed against their will? The Act's default rules make this very difficult. A specific expulsion clause — triggered by defined events like fraud, criminal conviction, or serious breach of the agreement — gives the partnership a practical tool without forcing dissolution.

Financial Records and Reporting

The agreement should require:

Dispute Resolution

Partner disputes are common. Rather than heading straight to court, consider a tiered resolution clause:

  1. Direct negotiation — partners attempt to resolve in good faith within 30 days.
  2. Mediation — an independent mediator assists if negotiation fails.
  3. Arbitration or litigation — the last resort, with the agreement specifying jurisdiction (Ontario).

A dispute resolution clause does not prevent all conflict, but it creates a structured path that is faster and cheaper than going to court immediately.

Term and Dissolution

State whether the partnership has a fixed term or is indefinite. Describe the circumstances under which the partnership dissolves:

Also include a winding-up process: how assets are liquidated, debts are paid, and the remaining value is distributed among partners.

Frequently asked questions

Do we legally need a written partnership agreement in Ontario?

No — a partnership can exist without any written agreement. But without one, the Partnerships Act default rules apply, and they are almost never what the partners actually intended. The cost of a proper agreement is small compared to the cost of fighting over terms that were never decided.

Can we use a template partnership agreement from the internet?

Generic templates may miss Ontario-specific nuances and almost certainly will not reflect your unique deal. A lawyer can draft or review a template in a few hours and flag the clauses that matter most for your situation.

When should we update our partnership agreement?

Review it whenever there is a significant change: a new partner is admitted, a partner leaves, the business pivots, or the partners' financial contributions change materially. Outdated agreements are almost as dangerous as no agreement at all.

What if we already operate as a partnership with no agreement — is it too late?

Not at all. Partners can put a written agreement in place at any time. You may need to address how existing assets and contributions are characterized, but a retroactive (or prospective) agreement is always better than operating on the defaults indefinitely.
