The client
A parent in the Kingston market keeping the matrimonial home after separation. The separation agreement requires an equalization payout of $110,000 to the departing spouse — home equity that has to be funded somehow, since neither party wants to force a sale of the family home.

Clean repayment history
The refinance itself is comfortably inside conventional lending limits — the question was never the loan-to-value:
| Refinance structure | Figure |
|---|---|
| Existing mortgage + equalization payout | $400,000 |
| Appraised home value | $540,000 |
| Loan-to-value | 74.1% |
The problem
A 74.1% loan-to-value refinance is well within the 80% conventional ceiling — funding the payout was never the structural problem. The problem was qualifying for the new payment on the income actually available.
GDS on salary alone
- ▸Housing costs: qualifying payment $2,849/mo + tax $320 + heat $140 = $3,309/mo
- ▸GDS: $3,309 ÷ $7,667 salary = 43.2% — over this lender’s 39% ceiling
- ▸The $850/mo in child support, documented under the separation agreement, was initially left off the application entirely
The support income was real, ongoing and already flowing into the same bank account every month — it simply had not been packaged the way this lender needed to see it before it would count.
The numbers
This is a refinance, not a purchase, so there is no CMHC premium and no insured ratio ceiling in play — the 39%/44% figures referenced here reflect the widely used industry-standard GDS/TDS ceiling most conventional lenders apply, mirroring but not identical to CMHC's insured maximums.
| The refinance numbers | Amount |
|---|---|
| Existing mortgage balance | $290,000 |
| Equalization payout | +$110,000 |
| New refinance amount | $400,000 |
| Rate & payments | Figure |
|---|---|
| Contract rate — illustrative refinance pricing | 5.19% |
| Minimum qualifying rate — greater of contract + 2% and 5.25% | 7.19% |
| Monthly P&I at the qualifying rate — the ratios run on this | $2,849 |
| Monthly P&I at the contract rate | $2,370 |
GDS and TDS, with and without support income
| Ratio | Salary only | Salary + support |
|---|---|---|
| Income used | $7,667/mo | $8,517/mo |
| Housing costs (GDS numerator) | $3,309/mo | $3,309/mo |
| GDS vs. the 39% ceiling | 43.2% ✗ | 38.9% ✓ |
| TDS with the $310 car loan added | — | 42.5% ✓ |
The gap between the two GDS figures is exactly the $850 of monthly support income — once it is counted, the file clears the ceiling with just over half a point to spare. Nothing about the housing cost changes; only whether the income used to measure against it includes support already flowing into the household.
The solution
An FSRA-licensed Ontario mortgage agent rebuilt the application around the support income the first submission had left out.
First, confirmed the payout structure. At 74.1% loan-to-value, the refinance itself was never going to be the obstacle — the file needed to qualify for the payment, not just fund the payout.
Second, documented the support income to this lender’s standard. Support-income policy varies by lender; this one required the separation agreement itself plus six months of deposit history showing the payments actually landing, on time, in the account used for the application.
Third, sequenced the payout with the title transfer. The equalization payment and any adjustment to the matrimonial home’s registered ownership were timed to close together with the refinance, so funds moved only once everything was in place.
The broader question of whether a HELOC or a full refinance is the better tool for accessing home equity applies here too — in this file, the size of the payout and the need to lock in a fixed structure both pointed to a straightforward refinance.
The outcome & what stayed off the closing statement
Approved at GDS 38.9% / TDS 42.5%, and the home was kept — no forced sale, no scramble to find a buyer under a separation deadline. One thing worth stating plainly: Ontario land transfer tax does not apply on this file at all, since a refinance does not transfer title to a new owner the way a purchase does.
The average home price in this Canadian home-price context has climbed enough over the years that equalization payouts on longer-held homes are frequently larger than either party expects — budgeting the refinance early in the separation process, not after the agreement is signed, avoids surprises.
What to take from this file
- 01Support income has to be documented to the lender’s own standard, not just asserted. This file needed the separation agreement plus six months of deposits — policy on exactly what counts varies by lender.
- 02A high loan-to-value equalization refinance is not automatically a hard file. At 74.1% LTV here, the structure was routine; the qualification on income was the actual work.
- 03The qualifying rate, not the contract rate, decides the ratios. This file qualifies at 7.19% and pays at 5.19% — nearly a $480-a-month gap between the two.
- 04A refinance does not trigger land transfer tax. Do not budget for it, and do not let a client assume it applies just because a large sum of money is changing hands as part of the separation.
