The client
A buyer purchasing at $365,000 in Gatineau, Quebec, whose credit report appeared to show two active auto loans at $460/mo each -- both, in fact, describing the same debt.

What changed
The loan was sold to a new servicer
Mid-term, without updating the original listing
The problem
An auto loan sold mid-term to a different financial institution is common enough to be routine -- dealer-arranged financing gets transferred to a bank or a captive finance company as a normal course of business. What is not routine is the original creditor's own tradeline failing to update: it should have read 'closed, transferred' the moment the sale completed, but instead kept reporting as an open account at its original payment, right beside the new servicer's own current listing for the identical debt.
One debt, reported as two
- ▸The original creditor's tradeline: still showing open, $460/mo, months after the loan was sold and should have closed
- ▸The new servicer's tradeline: also open, $460/mo, correctly reflecting the same debt under new ownership
- ▸A lender's system reading both at face value counts $920/mo in auto-loan payments for a debt that only ever cost $460
GDS on this file was never in question -- 37.0% throughout, well inside CMHC's 39% maximum. The duplicate auto-loan listing was the entire reason total debt service looked like a decline.
The numbers
Reconciling the two tradelines into the one debt they actually describe moved total debt service by exactly the size of the duplicate -- nothing else on the file, including the applicant's own credit score, ever changed.
| Reconciling one debt, two tradelines | Amount |
|---|---|
| Insured mortgage (10% down, band 3.10%) | $338,684 |
| Qualifying payment at 6.65%, 25 years | $2,299/mo |
| Property tax and heat | $405/mo |
| Real auto loan (single payment) | $460/mo |
| Total debt service | Counting both tradelines | Counting the real debt only |
|---|---|---|
| Mortgage payment + tax + heat | $2,704 | $2,704 |
| Real auto-loan payment | $460 | $460 |
| Duplicate phantom payment | $460 | — |
| Total debt service | 49.6% | 43.3% |
At 49.6%, the file read as a clear decline against CMHC's 44% maximum. Once the duplicate was removed, it cleared at 43.3% -- inside the ceiling, but only by eight tenths of a point, which is exactly why catching the duplicate mattered rather than being a nice-to-have.
The solution
A courtier hypothécaire licensed under Quebec's Act respecting the distribution of financial products and services treated the two identical payment amounts as a red flag worth chasing, not a coincidence.
First, pulled both tradelines side by side. Same original loan amount, same origination date, same monthly payment -- the pattern of a single debt reported twice, not two separate loans.
Second, contacted both the original creditor and the new servicer. Obtained a letter from each cross-referencing the original and new loan numbers, the exact transfer date, and a continuous payment history spanning the sale.
Third, gave underwriting the cross-referenced letters together, not the bureau dispute process alone. A formal bureau dispute can take weeks to resolve; the creditor letters let underwriting exclude the stale listing immediately, on the file's own timeline.
The outcome
The purchase funded insured at 4.65%, GDS at 37.0% and TDS at 43.3%, both inside CMHC's maximums, with Quebec's welcome tax on the purchase coming to $3,586.
GDS never moved -- it was 37.0% throughout, since an auto loan has nothing to do with housing costs. The reconciliation only ever touched total debt service, and by design: the point was removing a duplicate, not targeting a specific ratio.
What to take from this file
- 01A loan sale doesn’t always close the original tradeline cleanly. 'Closed, transferred' is what should happen; a stale 'open' listing surviving the sale is a known failure mode, not a rare one.
- 02Two identical payment amounts on the same bureau file is a pattern worth chasing. Same amount, same origination date, is a strong signal of one debt reported twice.
- 03Go to both creditors, not just the newest one. Only the original creditor can confirm the old tradeline should have closed; only the new servicer can confirm the current one is accurate.
- 04A cross-referenced letter moves faster than a formal bureau dispute. Underwriting can act on documentation immediately; a dispute resolution has its own multi-week timeline.
- 05A file sitting just over a ratio ceiling deserves a second look at every line, not just the largest one. The auto loan wasn't the biggest number on this file -- it was the one that was wrong.
