Partnership vs. Joint Venture in Canada: Key Differences in Liability, Structure, and Tax
A partnership and a joint venture are not the same thing, though Canadian business owners frequently use the terms as if they are. The distinction matters because the two structures carry different liability profiles, different tax treatment, different governance requirements, and different legal consequences when things go wrong.
The short version: a partnership is an ongoing business relationship between parties who share profits, losses, and liability. A joint venture is a collaboration on a specific project, typically governed by contract, where parties maintain their separate legal identities and limit their involvement to what they’ve agreed to contribute. Choosing the wrong structure or failing to document the right one creates problems that surface later, often in the worst possible circumstances.
What Is a Partnership in Canada?
Under Ontario’s Partnerships Act and its counterparts in other provinces, a partnership is defined as the relationship that exists between persons carrying on a business in common with a view to profit. The definition is intentionally broad and courts have found partnerships to exist even where parties explicitly said they weren’t in one, if the conduct and economics of the arrangement looked like a partnership.
That last point matters more than most founders realize. If two businesses are sharing profits from an ongoing activity, conducting business together under a common name, and making joint decisions about operations, a court may conclude a partnership exists regardless of what the parties called it. The liability consequences of an unintended partnership are significant.
There are three main forms of partnership in Canada.
General partnerships are the default form. All partners share in management, and all are jointly and severally liable for the debts and obligations of the business including each other’s acts. That means a creditor can pursue any partner personally for the full amount of a partnership debt, not just their proportionate share. Personal assets are exposed.
Limited partnerships require at least one general partner with full liability and one or more limited partners whose liability is capped at the amount they invested. Limited partners cannot participate in management without risking reclassification as general partners and losing their liability protection. Limited partnerships are common in private equity, real estate investment, and fund structures. They must be registered under Ontario’s Limited Partnerships Act.
Limited liability partnerships (LLPs) are available only to regulated professions in Ontario lawyers, accountants, and others whose governing legislation permits it. An LLP limits each partner’s personal liability for the negligence or malpractice of other partners while preserving pass-through taxation. For more detail on how LLPs work and who qualifies, see our guide to Limited Liability Partnerships in Ontario.
Partnerships don’t pay income tax at the entity level. Income and losses flow through to the partners proportionally, and each partner reports their share on their personal return. The partnership files a T5013 Partnership Information Return annually, which allocates income and losses to partners, but the tax itself is paid at the partner level. For higher-earning partners, this means income is taxed at top personal marginal rates there’s no ability to accumulate retained earnings at a lower corporate rate the way a professional corporation or holding company structure allows.
What Is a Joint Venture in Canada?
A joint venture is a contractual arrangement between two or more independent parties to collaborate on a specific project, transaction, or business objective while each party maintains its separate legal identity. Unlike a partnership, a joint venture is not defined or regulated by a specific statute. It is primarily a creature of contract, and its terms, scope, and duration are whatever the parties agree to.
Common examples include real estate development projects where two developers pool resources for a single building, technology companies co-developing a specific product without merging their broader businesses, or two manufacturers jointly tendering on a government contract they couldn’t fulfill alone. The defining characteristic is that the collaboration is bounded; once the project is complete, or the agreed objective is reached, the joint venture ends.
Because joint ventures have no statutory definition, the joint venture agreement is the document that governs everything: what each party contributes, how decisions are made, how profits and losses are shared, what happens if the project fails, and how the arrangement terminates. A poorly drafted joint venture agreement or the absence of one leaves parties exposed to disputes that have no statutory backstop to resolve them.
Incorporated vs. Unincorporated Joint Ventures
One of the most practically important distinctions in joint venture structuring is whether the parties create a new legal entity to carry out the project or keep the arrangement purely contractual.
An unincorporated joint venture is a purely contractual arrangement. The parties sign a joint venture agreement, contribute resources, and share in the results, but no new company is formed. Each party deals with the project’s assets, revenues, and liabilities directly. Tax treatment passes through to each party according to their respective tax position. Liability exposure depends on the contract, typically limited to each party’s agreed contribution, but there is no separate legal shield.
An incorporated joint venture involves creating a new corporation to carry out the project. The joint venture parties become shareholders in that corporation, which enters contracts, owns assets, and incurs liabilities in its own name. The corporation is a separate legal entity, which generally limits each party’s liability to their equity investment. The trade-off is that the corporation is taxed independently, and profit extraction, whether as dividends or management fees, involves additional tax considerations. Corporate tax planning is particularly important in incorporated JV structures.
The choice between incorporated and unincorporated structures is driven by the project’s risk profile, duration, and tax objectives. Projects involving significant third-party liability or long durations often favor incorporation. Shorter, lower-risk collaborations often keep the arrangement contractual.
When Courts Find a Partnership Despite a “Joint Venture” Label
One of the most common structural errors is labeling an arrangement a “joint venture” when it legally constitutes a partnership. Canadian courts look past the label and examine the substance: are the parties sharing profits from an ongoing business? Are they jointly conducting operations? Are they presenting themselves as a common enterprise to third parties?
If the answer to those questions is yes, a court may find a partnership exists with all the joint and several liability that comes with it regardless of what the agreement calls the arrangement. This is particularly relevant in real estate joint ventures and ongoing service collaborations where profit-sharing arrangements look economically indistinguishable from a partnership.
The practical implication: if you want the liability protection of a joint venture rather than the open-ended exposure of a general partnership, the agreement and the conduct of the parties must both reflect that. Calling something a joint venture in a contract while operating it as a shared ongoing business doesn’t protect you.

Which Structure Is Right for Your Situation?
For an ongoing business between two or more parties who will share management and profits indefinitely, a partnership or more likely a corporation is the right vehicle. For regulated professionals sharing a practice, an LLP provides the right combination of pass-through taxation and liability protection.
For a defined collaboration on a specific project where the parties want to preserve their independent businesses, a joint venture is the right framing, but the structure (incorporated or unincorporated) and the agreement are where the real work lies.
If you’re unsure which structure fits your situation, the answer usually depends on three questions: How long will the arrangement last? How much liability are you willing to share with your counterpart? And what are the tax objectives for each party? A corporate lawyer can work through those questions with you before any structure is committed to. Our overview of selecting the right business structure covers the broader landscape.
