Steinbach revolving-utilization cleanup

the credit-score floor, not the ratios, was the block

A Steinbach household's revolving cards sat at 90% utilization ahead of a pre-approval, pulling both bureau scores below CMHC's 600 floor even though their debt-service ratios already cleared the caps. Paying the balances down to 9% utilization lifted the score above 600 and cut TDS from 42.0% to 35.9%.

CMHC’s minimum credit-score floor for an insured file

Anonymized illustration. The borrowers, dollar figures, and rates in this file are an illustrative composite — no real client is identifiable, and any rate shown is illustrative, not a quote. The rules are real: every regulatory figure is cited to its source in the Sources section, and the math computes exactly as shown.

The client

A salaried couple, both multi-year T4 employees, pre-approving for a purchase in Steinbach, the fast-growing market southeast of Winnipeg. Their income was clean and documented and their repayment history had no missed payments anywhere — the file looked routine until the bureau pull came back.

Borrowers

Salaried couple, both on T4s

Multi-year tenure with their employers

Combined gross income

Three cards, $20,000 combined limit

$18,000 owing before cleanup

New purchase

Property tax $220/mo; heat estimate $110/mo

Down payment

The problem

Their own bank pulled both bureaus and declined the pre-approval on the spot. Neither score cleared the 600 floor CMHC sets for a default-insured file — a hard gate, not a policy preference, and the bank’s system stops there regardless of income or ratios. The cause was not missed payments; it was credit utilization. All three revolving cards were running near their limits — $18,000 owing against a combined $20,000, or 90% utilization — and utilization is one of the heaviest-weighted inputs into a Canadian credit score. Both bureaus sat below 600.

The instructive part of this file is what the ratios said once the broker actually ran them: at the qualifying rate, GDS came to 29.2% and TDS to 42.0% — both already inside CMHC’s 39%/44% caps, even carrying the full $540 in minimum card payments the 90% balances demanded. Canada’s household debt-service ratio gives useful context for how ordinary a file this actually was on the debt-service side. The math was never the obstacle. The score was.

That distinction matters because the two problems get fixed in completely different ways, and a broker who misreads one for the other wastes weeks. A TDS breach gets fixed by raising income, lowering debt payments, or restructuring the loan — none of which was needed here. A utilization-driven score sits below the floor because of how heavily the “amounts owed” component is weighted in Canadian scoring models, independent of whether the underlying debt is affordable. Two clients with identical income, identical debts and identical payment history can carry scores forty or fifty points apart purely on how close each sits to its credit limits at the moment the bureau reports. Nothing about this couple’s file was actually risky by the numbers; the bureau simply had no way to know that from a 90% utilization snapshot.

The numbers

First, the loan itself. At 10% down this is an insured file, so CMHC’s ratio caps and 600-score floor are hard requirements, not lender discretion.

Structuring the insured purchaseAmount
Purchase price$310,000
Down payment (10%)−$31,000
Base mortgage (90% LTV)$279,000
CMHC premium — 3.10% in the 85.01–90% LTV band, capitalized+$8,649
Total insured mortgage$287,649

Minimum qualifying rate — greater of contract + 2% and 5.25% — comes to 6.79% against a 4.79% contract rate (illustrative, not a quote). Monthly P&I at the qualifying rate is $1,978; at the contract rate, what they will actually pay, $1,639.

GDS — already fine, before and after

GDS (new home only)Monthly
P&I at the qualifying rate$1,978
Property tax$220
Heat (lender-standard estimate)$110
Housing costs $2,308 ÷ income $7,917 → GDS 29.2% — well under the 39% cap

TDS before and after the paydown

The minimum-payment convention here — 3% of the revolving balance — is a common illustrative figure; issuers set their own formulas.

TDS lineBefore (90% utilization)After (9% utilization)
Housing costs (GDS numerator)$2,308$2,308
Car loan$480$480
Card minimum payment (3% convention)$540$54
TDS vs. the 44% cap42.0%  ✓35.9%  ✓

Both numbers already clear 44% — the cleanup improved TDS by seven points, but it never had to. Utilization fell from 90% to 9% ($18,000 down to $1,800 across the $20,000 combined limit), which is what actually moved the score above 600.

Unlike Ontario’s 8% retail sales tax on the default-insurance premium, Manitoba charges no sales tax on mortgage default insurance at all — the $8,649 premium simply capitalizes into the mortgage with nothing extra due in cash on that line.

№ 04

The solution

A Manitoba Securities Commission–licensed mortgage broker diagnosed the decline correctly before touching anything else: this was a score problem wearing a ratio-sounding name. Re-running GDS and TDS confirmed the debt-service side was never going to be the fight.

The paydown plan. Rather than a vague instruction to “pay down cards,” the broker built a specific schedule — which card, how much, in what order — targeting 9% combined utilization ($1,800 across the $20,000 limit) rather than zero, since a small reported balance on an active, well-aged card is not a problem and full payoff of a card sometimes closes it, which can hurt the file in a different way. The highest-utilization card came down first, since per-card utilization on the individual account can matter almost as much to the score as the combined figure across all three, and the plan targeted a similar band on each card rather than emptying one while leaving another maxed.

Documented, not just achieved. The submission carried 60 days of statements showing the balances falling in the planned sequence, not just a single after-the-fact snapshot — underwriters want to see the trail, not just the destination.

Timed the resubmission. Utilization reporting lags the statement date at each issuer, so the broker waited for a confirmed post-cycle bureau refresh before resubmitting, rather than resubmitting the day the last payment cleared and risking a stale pull.

№ 05

The outcome & staying clean to funding

Both bureau scores cleared 600 on the refreshed pull; the file went back in as an ordinary insured purchase. Approved and funded: insured at 90% LTV, 25-year amortization, 5-year fixed term, with TDS landing at 35.9% and GDS at 29.2% — comfortable margin on both.

Cash due at closing (beyond the down payment)Amount
Manitoba land transfer tax on $310,000 — nil on the first $30,000, then marginal brackets to 2.0% above $200,000$3,850
Legal fees, title insurance & adjustmentsvaries

No sales tax applies to the premium in Manitoba, so the $8,649 CMHC premium is the only insurance-related figure on this file — it capitalizes into the mortgage rather than adding a cash line at closing.

What to take from this file

  • 01Utilization drives the score; debt-service math drives the ratios — know which one actually declined the file before you touch either. On this file TDS was already inside 44% before anything changed.
  • 02Target a utilization band, not zero. 9% reported and active can serve the file better than a fully paid, potentially closed card.
  • 03Document the paydown with statements across the whole window, not a single after-the-fact balance — underwriters credit the trail.
  • 04Time the resubmission to a confirmed post-cycle bureau refresh. Reporting lags the payment by weeks at most issuers.
  • 05Recheck utilization right up to funding. A utilization spike before closing on an unrelated purchase can undo this exact fix days before funds are due.
