Shared equity mortgages offer a path to homeownership by reducing the amount you need to borrow — but at the cost of sharing your future home equity with a partner. Here is how these programs work in Canada, what options are currently available, and whether they make financial sense.
How shared equity works
In a shared equity arrangement, a partner (government or private) contributes funds toward your home purchase. In return, they receive a share of the home’s future value.
Example: $500,000 home purchase
| Component | Without Shared Equity | With 10% Shared Equity |
|---|---|---|
| Purchase price | $500,000 | $500,000 |
| Your down payment | $25,000 (5%) | $25,000 (5%) |
| Shared equity contribution | — | $50,000 (10%) |
| Your mortgage | $475,000 | $425,000 |
| CMHC insurance | $19,000 (4.00%) | $10,625 (2.50%) |
| Monthly payment (5%, 25 yrs) | $2,782 | $2,489 |
| Monthly savings | — | $293 |
You save $293/month — but the equity partner owns a share of your home’s future value.
What you owe at sale
| Home Sells For | Appreciation | Equity Partner Gets (10% share) | Your Gain |
|---|---|---|---|
| $550,000 | +$50,000 | $55,000 (original $50K + $5K share of gain) | $45,000 |
| $600,000 | +$100,000 | $60,000 | $90,000 |
| $700,000 | +$200,000 | $70,000 | $180,000 |
| $450,000 | −$50,000 | $45,000 (shares the loss) | Loss of $30,000 |
As the home appreciates, you give up a growing dollar amount to the equity partner, even though their contribution was fixed at $50,000.
Programs available in Canada (2026)
Federal programs
| Program | Status | Details |
|---|---|---|
| first-time home buyer Incentive (FTHBI) | Discontinued (March 2024) | Offered 5% (resale) or 10% (new build) shared equity. Repayment after 25 years or at sale. Low uptake due to price caps ($500K–$600K in select markets) |
Provincial and municipal programs
| Program | Province | How It Works |
|---|---|---|
| Attainable Homes Calgary | Alberta | Below-market homes with shared equity. Repay equity share at sale |
| Trillium Housing | Ontario | Affordable housing shared equity partnerships — limited availability |
| BC Housing programs | British Columbia | Various equity-share programs through BC Housing partnerships |
| CMHC Seed Funding | National | Provides seed funding for affordable housing development — not direct to buyers |
Program availability changes frequently. Check with your provincial housing authority for current options.
Private shared equity companies
| Company | Model | Typical Terms |
|---|---|---|
| Ourboro | Co-invests in your home alongside your down payment | Contributes up to 15% of purchase price. Takes a share of appreciation. Buyout within 5 years |
| Key (formerly Arrive Home) | Down payment assistance for shared equity stake | Provides up to $100,000 toward down payment. Share of appreciation at sale or buyout |
| Other private programs | Varies | Terms differ widely — equity share, minimum terms, buyout conditions |
Caution: Private shared equity agreements are complex financial contracts. Have a real estate lawyer review any agreement before signing.
The math: shared equity vs larger mortgage
The key question is whether the equity you give up costs more or less than the additional mortgage interest you would have paid otherwise.
Scenario: $500,000 home, 5% annual appreciation, 10-year hold
| Path | Monthly Cost | Equity at Sale (10 yrs) | Total Interest/Cost Paid | Net Equity |
|---|---|---|---|---|
| Standard mortgage ($475K) | $2,782 | $814,447 − $357,844 balance = $456,603 | $176,987 interest | $456,603 |
| Shared equity ($425K + $50K partner) | $2,489 | $814,447 − $320,175 balance − $81,445 equity share = $412,827 | $158,316 interest + $81,445 equity share | $412,827 |
The shared equity path saves you $18,671 in interest over 10 years but costs you $81,445 in equity sharing — a net cost of $62,774. In a rising market, shared equity is almost always more expensive than simply borrowing more.
When shared equity wins
Shared equity is financially advantageous only when:
- Home prices are flat or declining — the equity partner shares the loss
- You literally cannot qualify for a larger mortgage — shared equity is the only way into the market
- The equity share percentage is small relative to appreciation — uncommon in major Canadian markets
Pros and cons
| Pros | Cons |
|---|---|
| Lower monthly payments | Give up a share of future appreciation |
| Smaller mortgage — less interest | In a rising market, equity share cost exceeds interest savings |
| Lower CMHC insurance premium | Complex agreements with buyout timelines |
| Downside protection — partner shares losses | May restrict renovations or how you use the property |
| Can bridge the affordability gap | Limited program availability in Canada |
| No monthly payments on the equity contribution | Must repay equity partner at sale or after set period |
Key terms to understand in any shared equity agreement
Before signing any shared equity agreement, ensure you understand:
| Term | What to Check |
|---|---|
| Equity share percentage | Is it proportional to their contribution, or do they take a larger share? |
| Appreciation calculation | Based on appraised value or sale price? Who pays for the appraisal? |
| Maximum term | When must you repay? 10 years? 25 years? At sale only? |
| Buyout option | Can you buy out the equity partner early? At what price? |
| Renovation approval | Do you need the equity partner’s permission for renovations? |
| Refinancing | Can you refinance your mortgage without triggering the equity repayment? |
| Occupancy requirements | Must you live in the home? Can you rent it? |
| Depreciation sharing | Does the equity partner share losses, or is there a minimum repayment floor? |
| Transfer/sale restrictions | Any restrictions on who you can sell to or when? |
Alternatives to shared equity
| Alternative | How It Helps | Trade-Off |
|---|---|---|
| Gifted down payment | Family gift increases down payment — no equity sharing | Requires family with available funds |
| Co-ownership | Buy with friend/family to pool resources | Joint liability, exit complexity |
| FHSA + HBP | Use FHSA ($40K) + RRSP HBP ($60K) for larger down payment | Requires saving time |
| Insured mortgage (5% down) | Buy with minimum down and CMHC insurance | Higher monthly payments, insurance premium |
| Rent and save | Wait and save for a larger down payment | Risk of prices rising further while saving |
| Secondary suite income | Buy with a rental suite to offset costs | Must qualify with property type, manage tenants |
The bottom line
Shared equity mortgages reduce your monthly payments and can make homeownership accessible when you cannot qualify on your own. But in a market where Canadian home prices have historically appreciated 3%–7% annually, the equity share you give up almost always costs more than the mortgage interest you save. Only consider shared equity if you truly cannot buy without it — and always run the numbers with different appreciation scenarios before signing.
