Key takeaways
  • A real estate joint venture can be set up as a partnership, a corporation or a simple co-ownership, so the structure is worth choosing deliberately with a lawyer and an accountant.
  • Co-owners of Ontario land can be compelled to partition or sell the property, so an exit plan belongs in your written agreement.
  • Profit from buying property to flip or build and sell is treated by CRA as business income, not capital gain.
  • Land transfer tax, and the 25% Non-Resident Speculation Tax where it applies, should be priced into the deal before anyone signs.

Pooling money and skills is a common way to buy a rental building, assemble land or build and sell. One investor brings capital, another finds the deal, a third manages construction. The hard part is rarely the idea. It is deciding how the group holds the property and what happens when people disagree.

This article walks through the usual structure options, the terms a joint venture agreement should cover, and the legal and tax risks that surprise investors. It is general information, not advice. The right structure depends on your goals, your tax position and who is in the group, so a lawyer and an accountant should confirm the details.

What a joint venture actually is

"Joint venture" is a business label, not a single legal form. It describes two or more people working together on a project, usually one property or one development, with an agreed split of money, work and profit. Who holds title, who signs the contracts and who owes what to whom are the practical questions to settle in writing.

Because the label does not decide your rights, a handshake or an email thread is a weak foundation. Real estate projects run for months or years, involve large sums and often end in a sale. Disagreements about money, timing and control are common, and a clear written agreement is what you will rely on when they happen.

The three usual structures compared

Most groups choose among a partnership, a corporation, or direct co-ownership of the land. The table gives a plain-language comparison. The details of each depend on the documents you sign and your tax situation.

StructureHow it generally worksPoints to weigh
PartnershipThe investors carry on the project together and share profit under a partnership agreement.Ask how liability is shared, who can bind the group, and how tax is reported.
CorporationThe investors hold shares in a company that owns the property. A shareholders' agreement sets the rules.Ask about separate liability, how profits are paid out, and how shares can be sold or transferred.
Co-ownershipThe investors are named together on title and own the land directly.Ask what happens if one owner wants out, defaults or dies, and whether a mortgage ties everyone together.

Some groups combine these, for example a corporation that owns the land with the investors holding shares through their own companies. Mixing structures can solve one problem and create another, which is why an accountant and a lawyer usually look at the plan together before any money moves.

What your joint venture agreement should cover

Whatever structure you choose, the written agreement is where you decide things in advance, while everyone still gets along. These are the topics most worth settling.

The exit plan matters more than most investors expect. Under the Partition Act, joint tenants, tenants in common and other interested parties in Ontario land can be compelled to partition or sell the property. If you co-own title and a partner wants out, that rule is part of the background, so the agreement should say how and when an exit happens rather than leaving it to a court.

Tax and cost risks to plan for

CRA says that profit from buying to flip, assign, or build and sell is business income, not capital gain, and that flips do not qualify for the principal residence exemption. CRA looks at the type of property, how long it was owned, the seller's history of similar sales, work done and the intention at purchase. A joint venture built around a resale should assume the profit may be taxed as business income and get tax advice on that basis.

Land transfer tax is a real cost of getting into the deal. For agreements after November 14, 2016, Ontario's provincial rate is 0.5% to $55,000, 1.0% from $55,000 to $250,000, 1.5% from $250,000 to $400,000 and 2.0% above $400,000, with 2.5% above $2,000,000 for land with one or two single family residences. The Non-Resident Speculation Tax is 25% and has applied since October 25, 2022, in addition to the general land transfer tax. If any member of your group is not a resident, ask early whether it can apply.

Putting the deal on title

Once the structure is chosen, the property has to be transferred into the right name. On Ontario's electronic land registration system, most transfer of title documents need two different lawyers to sign for completeness, with limited exceptions. A lawyer also cannot act for both transferor and transferee in a transfer of title, although a firm of two or more lawyers may act for both if different lawyers in the firm represent each party.

This is another reason to settle the structure before you sign an agreement of purchase and sale. Buying in the wrong name and then moving title can mean extra legal work, and a lawyer can tell you what applies to your situation.

What to do next

Frequently asked questions

Do we need a written agreement if we trust each other?

A written agreement is the safest course even among friends or family. It records what each person agreed to about money, control and exit, so memories do not have to settle a dispute later. A lawyer can tailor it to your structure.

Can a co-owner force the others to sell?

Ontario's Partition Act allows joint tenants, tenants in common and other interested parties in land to be compelled to partition or sale. Whether a court would order it in your case depends on the facts. A clear exit clause in your agreement can reduce the risk of that happening unexpectedly.

Will profit from a joint venture flip be a capital gain?

CRA says profit from buying to flip, assign, or build and sell is business income, not capital gain. It considers factors such as the type of property, how long it was owned and your intention at purchase. An accountant can tell you how this applies to your project.

Does the Non-Resident Speculation Tax apply to a joint venture?

The tax is 25% and applies in addition to the general land transfer tax. Whether it applies to your purchase depends on who is buying and how title is held, so confirm with a lawyer before you commit.
