The client
A household in Saint-Hyacinthe is buying a $315,000 home at 10% down, on $7,300/month of income. Months earlier, a credit-repair company had filed mass disputes against every negative item on the applicant's credit report, including two small, entirely accurate collection accounts.

The problem
A dispute filed with a credit bureau temporarily suppresses the disputed item while the furnisher investigates -- a legitimate process when the item is genuinely wrong, and a cosmetic, reversible one when it isn't.
What the mass-dispute filing actually did
- ▸Two small collection accounts, both accurate, were disputed alongside every other negative item on the file, as a matter of the credit-repair company's standard practice
- ▸Both accounts were suppressed from the score pending investigation -- not corrected, because there was nothing inaccurate to correct
- ▸Once the investigation closed, both accounts reappeared, and the resulting score swing risked triggering a lender's own fraud or quality-control re-review mid-file
Nobody disputed how either collection was calculated or reported -- the accounts were accurate from the start. The mass dispute simply took advantage of the investigation window to lift the score temporarily.
The numbers
Once the two collections were identified as accurate, the fix wasn't a further dispute -- it was paying them, permanently removing the volatility a temporary suppression had introduced.
| The insured purchase | Amount |
|---|---|
| Base mortgage (90% of purchase price) | $283,500 |
| CMHC premium -- 3.10% in the 85.01-90% LTV band | +$8,788 |
| Total insured mortgage | $292,288 |
| Ratio check at the qualifying rate | Figure |
|---|---|
| Payment at the qualifying rate (6.85%), 25 years | $2,020/mo |
| GDS (payment + $285 tax + $115 heat) ÷ $7,300 income | 33.2% |
| TDS (GDS numerator + $220 car loan) ÷ $7,300 income | 36.2% |
34 points of GDS and TDS were never the issue -- both sit comfortably inside CMHC's 39% and 44% maximums. The $615 in collections, paid outright, was the only number this file actually needed settled.
The solution
A courtier hypothécaire licensed under Quebec's Act respecting the distribution of financial products and services read the credit report's dispute history rather than taking the improved score at face value.
First, identified which items were under active dispute and why. Confirmed with the applicant that both collections were accurate -- the dispute had been filed as part of a standard mass-dispute service, not because either account was wrong.
Second, explained the risk of relying on a temporarily suppressed score. Once the credit-repair company's dispute window closed, the accurate items would reappear, and the resulting swing could trigger a lender's own re-review at the worst possible time in the file.
Third, paid both collections in full -- $615 -- and obtained paid-in-full confirmation letters. Removed the volatility permanently rather than leaving the file exposed to a mid-underwriting score change.
The outcome
The purchase funded insured at 33.2% GDS and 36.2% TDS, on a score that was genuinely, permanently improved rather than temporarily and reversibly suppressed, in line with the credit scores of Canadian mortgage borrowers more broadly.
Both ratios sit comfortably inside CMHC's 39% GDS and 44% TDS maximums; the file was never close to either ceiling.
What to take from this file
- 01A dispute filed on accurate information suppresses a score temporarily, not permanently. The negative item returns once the investigation closes -- it doesn't disappear.
- 02A credit-repair company's mass-dispute service treats every negative item the same way, whether it's wrong or not. Confirm which disputed items are genuine errors and which are simply accurate debts before relying on the improved score.
- 03Paying a small, accurate collection outright is often cheaper than the risk of riding a suppression. $615 settled permanently what a reappearing item could have cost in a stalled or re-reviewed file.
- 04A lender's fraud or quality-control review can be triggered by a score that moves the wrong way mid-file. Settling the underlying debts before submission avoids that swing altogether.
