The client
A couple in Drummondville's small machine shop, financed years earlier through the Canada Small Business Financing Program, carried a $150,000 loan personally guaranteed by both spouses — separate entirely from the $340,000 matrimonial home they were also dividing.
Matrimonial home
$340,000, Drummondville
$165,000 mortgage balance
CSBF business loan
$112,000 owing
Of a $150,000 original advance, both spouses as guarantors
Separation agreement
Business to remaining spouse
Silent on notifying the CSBF lender
Remaining spouse's income
$8,900/month
Business draw plus other income
The problem
The separation agreement assigned the machine shop, and its debts, to the spouse keeping it — a perfectly ordinary division of family property. But a personal guarantee on a Canada Small Business Financing loan is a contract between the departing spouse and the lender, not between the two spouses. An agreement neither of them showed the lender does nothing to that contract.
What the Canada Small Business Financing Regulations actually require
- ▸Under the current Canada Small Business Financing Regulations (SOR/99-141), a lender may release a guarantor while the loan remains in good standing
- ▸Alternatively, the guarantee may be replaced with a substitute guarantee or security of equal or greater value, with the lender's own consent
- ▸Neither happens automatically — both require an actual request to, and confirmation from, the CSBF lender itself
The loan was in good standing, with no missed payments — but nobody had actually asked the lender to release the departing spouse yet. Left alone, she would have walked away from the marriage still personally on the hook for a business she no longer had any part of.
The numbers
The home buyout itself was a straightforward refinance, entirely separate from the business loan — the two obligations never touch the same numbers.
| Refinancing the home buyout | Amount |
|---|---|
| Home equity | $175,000 |
| Departing spouse's 50% buyout | $87,500 |
| New refinance balance | $252,500 |
| Total debt service | Figure |
|---|---|
| Payment at the qualifying rate (6.90%), 25 years | $1,753/mo |
| Property tax | $285/mo |
| Heat (lender estimate) | $115/mo |
| Car loan | $260/mo |
| Total debt service | 27.1% |
27.1% leaves ample room on the remaining spouse's own income — the refinance itself was never the hard part of this file. Confirming the CSBF guarantee release before closing, so the departing spouse's exposure was actually gone and not just assumed gone, was.
The solution
A courtier hypothécaire licensed under Quebec's Act respecting the distribution of financial products and services treated the CSBF guarantee as a separate lender relationship to be closed out in writing, not a term of the separation agreement to take on faith.
First, obtained the current CSBF loan statement directly from the business's lender, confirming the $112,000 balance and that the loan was in good standing — the actual condition the regulations require before a release.
Second, had the remaining spouse formally request the departing spouse's release under the Canada Small Business Financing Regulations, rather than relying on the separation agreement's own assignment of the business to do that work.
Third, held the home buyout refinance open until the CSBF lender's written release letter was actually in hand, so the departing spouse's exposure to the business debt and her equity buyout from the home closed on the same clean date.
The outcome
The CSBF lender confirmed the release in writing once asked, the home buyout refinance funded at 4.90%, and total debt service settled at 27.1%.
Because this file is an uninsured refinance, CMHC's ratio maximums do not apply directly; the 27.1% figure is informational.
What to take from this file
- 01A separation agreement binds the spouses to each other, not a third-party lender. A personal guarantee on a business loan needs the lender's own release, regardless of what the couple agreed between themselves.
- 02Under the Canada Small Business Financing Regulations, release requires the loan to be in good standing, or a substitute guarantee of equal or greater value. Neither happens without an actual written request to the lender.
- 03Get the release in writing before treating a departing spouse's business exposure as closed. A verbal assumption, or a clause in the separation agreement alone, is not confirmation.
- 04A family business's debt and the matrimonial home's debt are two separate lender relationships. Closing one does nothing to the other; each needs its own paper trail.

- ▸the $150,000 original CSBF loan and $112,000 current balance — this business's own figures; every CSBF loan's balance and repayment history is individual.
- ▸the TDS figure — this is an uninsured refinance, so there is no CMHC ratio ceiling -- the number is informational.
