Toronto’s average home price hit $1,034,000 in the fourth quarter of 2025, according to Royal LePage data. For a single buyer, that means a down payment north of $200,000 and a monthly mortgage that eats up most of a take-home salary. Co-ownership — buying a home with people other than a spouse — is how more Canadians are answering that math.

Nearly 6% of Canadian homeowners already co-own with someone who isn’t their spouse or partner, and that share is growing. A 2023 Leger survey found that 89% of co-owners buy with family members, while 7% co-own with friends. The motivation is mostly financial: splitting costs lowers the barrier to entry, and dual incomes help buyers qualify for a larger mortgage. But the arrangement only works if the legal and personal sides are handled carefully. Here’s what you actually need to know.
What Co-Ownership Gets You — and What It Asks in Return
Co-ownership means two or more people buy a property together, sharing the mortgage, costs, and equity according to a formal agreement. It’s not the same as being joint tenants on a title with a spouse — it’s a deliberate financial structure for people who aren’t married to each other. A shared ownership arrangement can work across different property types, but the single-family detached home is the most common choice. What I tend to notice is that buyers who rush into co-ownership without a clear operating plan often run into problems that a few hours of paperwork could have prevented.
What Co-Ownership Actually Costs Compared to Buying Alone
Most people focus on the purchase price, but the real comparison is about what you pay per person and what you get for it. The table below uses Toronto’s average home price and a typical 20% down payment to show how the numbers shift when you split the load.

| Cost Factor | Buying Alone | Co-Ownership (2 people) |
|---|---|---|
| Home price | $1,034,000 | $1,034,000 |
| Down payment (20%) | $206,800 | $103,400 per person |
| Monthly mortgage (approx.) | ~$4,800 | ~$2,400 per person |
| Property type most common | Condo or smaller home | Single-family detached (76% of co-owners) |
That per-person saving is what makes co-ownership realistic for a lot of first-time buyers. The Storeys report notes that 38% of co-owners say the arrangement let them afford a larger property or one in a more desirable neighbourhood. But the monthly savings come with a trade-off: you’re jointly liable for the full mortgage. If one person stops paying, the other has to cover the gap or risk default. It’s also worth weighing how much you’d spend on shared property costs over time — utilities, repairs, property tax — all of which need to be divided and tracked.
Where Co-Ownership Arrangements Fall Apart
Most co-ownership problems aren’t about money. They’re about what wasn’t agreed on in advance. Here are the three gaps that cause the most trouble.
Skipping the Legal Agreement
Toronto lawyer Tanya Walker, quoted in the Toronto Star, says verbal deals or informal texts don’t protect anyone. A co-ownership agreement should cover ownership percentages, who pays what, how decisions are made, and what happens if someone stops paying. Without it, a single missed mortgage payment can put everyone’s credit at risk. The agreement should be signed before the purchase closes, not after. What I’d do is treat it like a pre-nup — uncomfortable to discuss, but far less painful than the alternative.
Leaving Roles and Responsibilities Vague
When nobody is assigned to manage repairs, track bills, or coordinate maintenance, small tasks get ignored. The research shows that assigning specific roles — conflict resolution, outdoor areas, property management, garbage removal — prevents the kind of friction that builds up in shared living. If two people both think the other is handling the leaking tap, the tap doesn’t get fixed. A simple role chart agreed on at the start saves a lot of awkward conversations later.
Not Planning an Exit Strategy
Life changes. Someone gets married, takes a job in another city, or simply wants their equity out. Without a written exit plan, a co-owner who wants to sell can be stuck for years, or the remaining owner can be forced into a sale they don’t want. Buyout clauses, right of first refusal, and forced-sale triggers should be in the contract. The Money.ca article also recommends prenuptial agreements for future spouses, so a co-owner’s marriage doesn’t complicate the shared ownership.
How to Set Up a Co-Ownership That Lasts
Getting the structure right from the start determines whether co-ownership works or turns into a legal and financial headache. Here’s what the process actually looks like in practice.
Finding the Right Co-Owner
Most people start with their social circle. The Leger survey found that 89% of co-owners buy with family, and 7% with friends. For those who don’t have a willing relative or friend, the app Husmates launched in Toronto in January 2025 with about 160 users. It uses an 80-question profile to match potential co-owners and hosts in-person events where members can meet. The key is finding someone whose financial situation, lifestyle, and timeline are compatible with yours — not just someone who can split the down payment.
Writing the Co-Ownership Agreement
This is the most important step. The agreement should cover ownership percentages, how mortgage and tax payments are split, who handles maintenance, what happens if someone misses a payment, and how decisions are made. It should also specify whether the property is held as joint tenancy or tenants in common — the difference affects what happens to a share if one owner dies. A lawyer experienced in real estate co-ownership should draft or review the document. If you’re unsure where to start with the legal questions, real estate lawyers on JustAnswer can help clarify the key clauses before you meet with a local solicitor.
Setting Up Roles, Meetings, and Shared Systems
The couples featured in the Toronto Star research meet regularly for two types of gatherings: one for project planning (reviewing quotes for repairs, agreeing on renovations) and one purely social. They also assign specific roles — someone handles the outdoor areas, someone manages repairs, someone coordinates garbage removal. For shared access to the property, a smart lock with keyless entry can eliminate the hassle of managing multiple physical keys for each co-owner. A shared document for tracking expenses and receipts also helps avoid arguments about who paid what.
Planning the Exit in Advance
The agreement should spell out what happens if one co-owner wants to sell and the other wants to stay. Typical options include a buyout at market value, a right of first refusal, or a forced sale if no agreement can be reached. The crowdfunded property model shares some of the same structural challenges — multiple owners, shared liability, and the need for clear exit terms. The same planning discipline applies: write it down before it’s needed.

Co-Ownership Won’t Solve Everything, but It Changes the Odds
The 32% of co-owners who made the decision after the Bank of Canada’s first interest rate hike in March 2022 understood something practical: when the market shifts against individual buyers, pooling resources is one of the few levers left. Co-ownership doesn’t eliminate the costs of homeownership — it redistributes them. The difference between a $240,000 down payment and a $120,000 one is the difference between waiting another decade and buying now. The success of the arrangement depends almost entirely on the quality of the agreement and the honesty of the conversations that happen before the keys are handed over.
