The client
A couple in Brandon, both salaried, went looking for their first home with clean-looking finances and one buried problem: a $740 collection on an old account, plus two 30-day late payments from roughly a year earlier, had left one applicant’s score at 588. Canadian mortgage borrowers typically carry scores well above that — see the credit-score statistics for Canadian mortgage borrowers — which is exactly why 588 stopped the file cold rather than just narrowing the options.

Met on paper by the 712 applicant alone
The problem
CMHC’s rule is that at least one borrower or guarantor needs a score of 600 or higher — and on paper, the 712 applicant already clears that floor. The file still stalled, because the couple needs both incomes to make the ratios work, and the lender’s own adjudication was unwilling to approve a joint file carrying a 588 without some remediation first.
Why 588 nearly killed the file anyway
- ▸The insurer’s 600-score gate is a minimum, not a green light — a lender can still apply its own manual review above that floor
- ▸A single unpaid $740 collection reports as an open, unresolved account, which reads worse than a small paid-off balance would
- ▸The two 30-day lates were about a year old — recent enough to still weigh on the file
On one income alone, the ratios don’t work — so both applicants, and both scores, had to be part of the same approved file. That reframed the job: not finding a lender that would ignore 588, but fixing it.
It is worth separating this from credit-repair marketing that promises to erase a low score overnight. Nothing here was erased. The collection got paid, which is a fact a bureau can verify; a secured card generated six months of new, clean payment history, which is a fact a scoring model can weigh; and the two 30-day lates simply kept aging, which is what eventually reduces their impact on their own. None of that happens on a lender’s decline letter — it happens on a calendar, which is why the broker’s first job was setting a realistic timeline, not shopping for a lender willing to overlook the number.
The numbers
At 8% down this is an insured purchase, so the loan runs through CMHC’s standard structure before the credit question is even relevant to the math.
| Structuring the insured loan | Amount |
|---|---|
| Purchase price | $289,000 |
| Down payment (8%) | −$23,120 |
| Base mortgage (92% LTV) | $265,880 |
| CMHC premium — 4.00% in the 90.01–95% LTV band, capitalized | +$10,635 |
| Total insured mortgage | $276,515 |
Minimum down payment on $289,000 is 5% of the purchase price, or $14,450 — the 8% put down here clears that floor with room to spare.
| Rate & qualifying payment | Figure |
|---|---|
| Contract rate (illustrative, not a quote) | 4.54% |
| Minimum qualifying rate — greater of contract + 2% and 5.25% | 6.54% |
| Monthly P&I at the qualifying rate — the ratios run on this | $1,859 |
GDS and TDS on the approved file
| Ratio line | Monthly |
|---|---|
| P&I at the qualifying rate | $1,859 |
| Property tax | $250 |
| Heat (lender-standard estimate) | $150 |
| Housing costs $2,259 ÷ income $8,000 → GDS 28.2% | ✓ |
| Existing instalment loan | $290 |
| Total obligations $2,549 ÷ income $8,000 → TDS 31.9% | ✓ |
The solution
An MSC-licensed Manitoba mortgage broker did three things.
First, confirmed the insurer floor was already met. The 712 score cleared the 600 gate on its own, so the file was never actually insurer-dead — the real obstacle was the lender’s own manual adjudication on the joint application.
Second, fixed the credit itself rather than shopping around it. The $740 collection was paid and documented, a secured card was opened, and six clean months of statements were built up before requesting a rescore — the kind of remediation covered in our piece on credit-repair claims that don’t work, and what actually moves a file.
Third, resubmitted once the score had actually moved, not before — the ratios don’t care why a score is low, only what it reads on the day of adjudication.
The outcome & the second pull
The rescore came back at 634 — understanding why a score moves between two pulls is what let the broker set realistic expectations for the wait. The file funded insured at 92% LTV with both applicants on it. Manitoba’s land transfer tax on $289,000 came to $3,430 in cash at closing; unlike Ontario, Quebec, or Saskatchewan, Manitoba charges no tax on the default-insurance premium itself, so that particular cash line simply didn’t apply here.
The couple's own instinct, at the first decline, was to ask whether the 588-score applicant should simply come off the application. That would have solved the credit problem and created a bigger one: on one salary alone, the housing costs already computed here would not have passed GDS at all. Fixing the score, slowly and on paper, turned out to be the only path that kept both the approval and both incomes on the file at the same time.
What to take from this file
- 01The insurer’s 600-score floor only needs one borrower to clear it, not both. Check that before assuming a joint file is dead over a low secondary score.
- 02Paying and documenting a small collection can move a score enough to matter within a few months. Plan the rescore timeline into the file instead of abandoning it.
- 03Manitoba charges no tax on the default-insurance premium. That’s a real, province-specific difference in cash needed at closing versus Ontario, Quebec, or Saskatchewan.
- 04The ratios don’t care why a score is low, only what it is on adjudication day. Resubmit once the number has actually moved.
- 05Minimum down payment tiers set the floor lenders check first — 5% under $500,000 — know it before quoting a client their real options.
