"CMHC spousal buyout" is the most common name people search for, but the program is actually offered by all three of Canada's default mortgage insurers — CMHC, Sagen, and Canada Guaranty. The eligibility rules across the three are functionally identical, and the lender (working with your broker) decides which insurer to use based on its own internal preferences. From your end, the difference is invisible.

This article covers what all three insurers actually require, the property and borrower limits that determine whether your file fits, what the premium costs at each loan-to-value tier, and the small details that decide whether your spousal buyout can be insured at all.

Why It's Called "the CMHC Program" Even Though Three Insurers Run It

CMHC (Canada Mortgage and Housing Corporation) is the largest and most recognized of Canada's three default mortgage insurers. Sagen (formerly Genworth Canada) and Canada Guaranty are private insurers that operate under the same federal regulatory framework. All three insure mortgages above 80% loan-to-value, all three follow the same federal rules on stress testing and amortization, and all three have nearly identical spousal buyout programs.

When a lender approves a spousal buyout mortgage, they submit it to one of the three insurers for insurance approval. The insurer reviews the file against its specific rules, approves or asks for additional information, and once approved, the file moves to closing. Borrowers don't choose the insurer — the lender does. As a borrower, the rules you need to satisfy are essentially the same regardless of which one ends up insuring your file.

This article uses "CMHC spousal buyout" interchangeably with "spousal buyout program" because that's the search term, but everything below applies to Sagen and Canada Guaranty equivalently.

The Six Core Eligibility Rules

For a spousal buyout to be insured under any of the three programs, six things must be true.

1. The borrower is buying out a former spouse or common-law partner. This sounds obvious, but the program is specific. It applies when the existing legal relationship is ending and one party is acquiring the other's interest in the matrimonial home. It doesn't apply to siblings buying each other out, business partners, or parents and children. Common-law relationships qualify, including in Alberta where the Family Property Act treats long-term common-law partners with property rights similar to married spouses — see our deeper guide on common-law separation and the matrimonial home in Alberta.

2. The property is the principal residence. The home being bought must be the matrimonial principal residence — where the family has been living. Rental properties, vacation homes, and investment properties don't qualify under the spousal buyout program. They have to be financed through standard refinance or investment property channels, which means the 80% LTV ceiling applies.

3. There is a signed separation agreement. The agreement must document the matrimonial property division, the buyout amount, and the parties' intent to settle the property issue through this transaction. Drafts, verbal agreements, and partial agreements don't satisfy the requirement. The lender's lawyer will review the document. For what the agreement actually has to say, see our separation agreement requirements guide.

4. Loan-to-value does not exceed 95%. This is the program's central feature. The new mortgage can be up to 95% of the home's appraised value, compared to 80% under a standard refinance. Files where the buyout pushes LTV above 95% can't be insured as a single spousal buyout mortgage — alternative paths include outside funds to bring the LTV down, layered private second financing, or a different program entirely.

5. Property value is under $1.5 million. Default insurance is not available on properties priced above $1.5 million. The cap was raised from $1 million to $1.5 million effective December 15, 2024 — a recent change that opened the program up to more files in higher-priced markets. In Calgary, where benchmark prices are well below the cap, this rarely binds. In Vancouver or Toronto it can. For homes above the cap, the buyout has to work under 80% LTV standard refinance rules, or use private financing.

6. The borrower qualifies under federal mortgage rules. The standard income, credit, and stress test requirements all apply. The qualifying rate is the higher of 5.25% or your contract rate plus 2%. Debt service ratios apply (typically 39% GDS and 44% TDS at A-lenders). For files where qualifying is tight, our guide to qualifying on one income after separation covers the workarounds.

Premium Costs at Each LTV Tier

Default insurance isn't free. The premium is added to the mortgage and amortized over its life — you don't pay it upfront, but it's a real cost. Premiums are based on loan-to-value:

Loan-to-Value Approx. Premium Premium on $400K Mortgage Premium on $570K Mortgage
Up to 80%No premium (standard refi)$0$0
80.01% – 85%~2.80%$11,200$15,960
85.01% – 90%~3.10%$12,400$17,670
90.01% – 95%~4.00%$16,000$22,800

Two notes on the premium math:

  • The premium is calculated on the new mortgage amount before the premium is added. The premium itself isn't insurable — it's added to the loan after the insurance calculation.
  • Alberta does not charge provincial sales tax on default insurance premiums. Some other provinces do (Ontario, Quebec, Saskatchewan, Manitoba). Alberta files come in cleaner on this dimension.

The premium feels expensive in the abstract, but in context: it's what unlocks an extra 15 percentage points of financing capacity (from 80% to 95% LTV), which often determines whether the buyout is possible at all. It's amortized into the mortgage payment, so the monthly cost impact is modest.

What "Use of Funds" Restrictions Actually Mean

One of the most consistently misunderstood parts of the spousal buyout program is what the funds can pay for. The rule is strict: the funds must be used to settle the matrimonial property division as documented in the separation agreement. They cannot be used to consolidate debt, fund renovations, or take cash out for any other purpose.

What this looks like in practice at closing:

  • The new mortgage funds flow from the new lender to the existing lender, paying off the old mortgage in full
  • The remainder flows to the lawyer's trust account
  • The lawyer disburses according to the separation agreement — typically a payment to the departing spouse to settle their share of the matrimonial property
  • Any remaining costs (legal fees, registration costs, title transfer fees) come out of the same closing funds
  • Nothing is paid to credit cards, lines of credit, contractors, or anyone outside the matrimonial property settlement

If the separation agreement explicitly settles other matrimonial property items through the buyout — for example, the agreement says the buyout payment includes equalization of RRSPs, vehicle equity, or joint debt repayment — those items can be funded as part of the buyout because they're documented matrimonial property. The agreement is the source of truth.

What If the Property is Above $1.5 Million?

Above the $1.5M ceiling, the spousal buyout program isn't available because the underlying default insurance isn't available. Three paths exist for higher-value properties.

Path 1: Fit the buyout under 80% LTV. If equity is large enough that the new mortgage stays at or under 80% of the home's value, a standard refinance can fund the buyout without insurance. No spousal buyout program needed, no premium, no $1.5M cap. Most high-value properties have substantial equity, so this is often workable.

Path 2: Layered second mortgage. The first mortgage covers up to 80% LTV under standard rules. A second mortgage from a private or alternative lender covers the gap between 80% and the actual buyout amount needed. The blended cost is higher, but the buyout closes.

Path 3: Bring outside funds. Family loans, savings, investment liquidations, or gifted funds can reduce the new mortgage amount enough to fit under 80% LTV. The advantage is keeping the financing in the prime channel and avoiding premium costs.

Common-Law and Same-Sex Spousal Buyouts

The program applies equally to common-law and same-sex couples whose relationship qualifies as a spousal relationship under the relevant provincial family law. In Alberta, common-law partners (called "adult interdependent partners" under the Adult Interdependent Relationships Act) acquire property rights similar to married spouses after meeting specific thresholds — typically three years of cohabitation, or one year with a child of the relationship, or entering into an adult interdependent partner agreement.

Lenders process common-law spousal buyouts the same way as married spousal buyouts. The separation agreement and the matrimonial property division are the operative documents — the relationship status determines whether the agreement has legal force, but the lender's process from application to closing is identical.

What Happens If the File Is Declined

Spousal buyout files can be declined at the lender level (income or credit doesn't meet underwriting standards) or at the insurer level (CMHC, Sagen, or Canada Guaranty doesn't approve insurance). Insurer declines are rare on clean files and usually relate to property issues — unusual zoning, environmental concerns, prior insurance claims on the property — rather than borrower issues.

If declined at the lender level, options include resubmitting to a different lender (different lenders have different appetites for support income, gift funds, and credit profiles), restructuring the file (smaller buyout, longer amortization, co-signer), or moving to a B-lender or private channel.

The decline is rarely the end of the road. It usually means the file needs to be packaged differently. We've worked files that were declined at the first lender and approved at the third. The right placement matters more than people expect.

The Practical Bottom Line

The CMHC spousal buyout program — and its equivalents at Sagen and Canada Guaranty — is the financing tool designed for one specific situation: a separation where one spouse is buying out the other's share of the matrimonial home and the buyout requires going above 80% LTV. The rules are strict but the benefit is real. For families that fit, the program often determines whether keeping the home is possible at all.

Whether your file fits comes down to six things: relationship type, property type, signed agreement, LTV, property value, and qualifying. Get those right and the program does what it's designed to do. Miss one and the file needs a different path.
