Key takeaways
  • Owning property together as joint tenants or tenants in common does not by itself create a partnership, even if the owners share profits.
  • In a general partnership every partner can bind the firm and is jointly liable for its debts, subject to the limited liability partnership rules.
  • Most of a joint venture is contract, so the exit, dispute and decision-making terms should be written down before money moves.

Two investors pooling money to buy or develop property usually start with a handshake and a shared spreadsheet. The harder questions come later: who decides, who is on the hook for a debt, and how does one person leave.

A joint venture is mostly a matter of what you agree in writing, with a few Ontario statutes in the background. This article covers that backdrop and the terms worth settling up front. It is general information, and the right structure depends on your plan.

A joint venture is mostly a contract

There is no single Ontario statute that sets out what a real estate joint venture must contain. The parties' agreement does most of the work. The statutes matter mainly because they supply default rules that apply when your agreement is silent.

Two of those defaults are worth knowing at the start. When land is granted to two or more people, they are treated as tenants in common, not joint tenants, unless the document clearly shows they are to take as joint tenants, and this applies even if the owners are spouses. That presumption does not apply to executors or trustees.

Co-ownership or partnership?

Investors often assume that sharing a property means being in a partnership. The law draws a line. Owning property together as joint tenants or tenants in common does not by itself create a partnership, even if the owners share profits from the property. A partnership exists where persons carry on a business in common with a view to profit.

DebtsDepends on what each owner signsEvery partner is jointly liable for all the firm's debts and obligations

The joint liability rule is subject to the provisions on limited liability partnerships. If limiting your exposure matters, ask a lawyer whether a partnership, a corporation or another structure fits your project. A venture that actively buys, improves and resells may look more like a business than passive co-ownership.

Terms to agree before money moves

Whatever the structure, put the working rules in writing. The list below covers the questions that most often cause trouble later.

If the property is being built or renovated, contractor payments bring in the Construction Act. Every payer under a contract or subcontract on which a lien may arise must keep a 10 per cent holdback. Decide who is responsible for holdbacks and for clearing any lien that is registered.

Holding title for each other, exits and disputes

Sometimes one investor holds title for both. CRA describes a bare trust as one where the trustee is essentially an agent for the beneficiaries. Bare trusts do not have to file a T3 return or Schedule 15 for taxation years ending on or after December 31, 2024 and before December 31, 2026, but reportable bare trusts may have to file for years ending on or after December 31, 2026. The definition of a reportable bare trust excludes some arrangements, such as related persons holding a property that is their principal residence. Because this area is changing, ask an accountant how it applies to you.

If the relationship breaks down and there is no agreed exit, the default is the Partition Act. Anyone with an interest in land in Ontario may bring an action or application for partition of the land or for its sale, and joint tenants and tenants in common may be compelled to make or suffer partition or sale.

There is an exception. Where jointly held land passed by will or intestacy, no partition proceeding may be taken until one year after the death. Separately, if a spouse is involved, the Family Law Act says no spouse may dispose of or encumber an interest in a matrimonial home unless the other spouse joins in or consents, or another listed exception applies. How these rules fit together on your facts is worth confirming with a lawyer. A court process is slow and uncertain, which is why a written exit clause is worth having.

What to do next

Frequently asked questions

Does sharing profits from a property make us partners?

Not by itself. Owning property together as joint tenants or tenants in common does not create a partnership, even if the owners share profits. A partnership exists where persons carry on a business in common with a view to profit.

Are we joint tenants or tenants in common if the deed is silent?

When land is granted to two or more people, they are treated as tenants in common unless the document clearly shows they are to take as joint tenants. This applies even to spouses. Executors and trustees are an exception.

Can one investor force a sale?

Anyone with an interest in Ontario land may bring an action or application for partition or sale. Special timing can apply, including a one-year wait where land passed by will or intestacy. A written exit clause is the better way to handle it.

Am I personally liable for my co-investor's debts?

In a general partnership, every partner is jointly liable for all the firm's debts and obligations, subject to the limited liability partnership provisions. Mere co-ownership of land does not create a partnership. The answer depends on your structure and what you signed, so get advice.
