The client
A buyer in Orillia is purchasing at $335,000, $33,500 (10%) down. Their Canada Student Loan is currently under the federal Repayment Assistance Plan (RAP), which sets a reduced, income-tested payment in place of the loan's original contractual minimum.

The problem
The federal Repayment Assistance Plan sets a reduced, income-tested payment for a borrower who qualifies, replacing the loan's original contractual minimum for as long as the borrower stays enrolled. Some bureau records don't reflect that change, still showing the higher original figure -- and a first lender's system pulled that stale number straight from the bureau instead of checking which payment the borrower was actually obligated to make.
Why the bureau figure and the actual payment diverged
- ▸The Repayment Assistance Plan is administered by the National Student Loans Service Centre (NSLSC), separately from how the bureau reports the loan
- ▸A bureau record can continue showing a loan's original contractual minimum even after RAP has reduced the borrower's actual required payment
- ▸Only the NSLSC's own confirmation letter reliably shows the payment a specific borrower is currently obligated to make
Priced on the bureau's stale figure, TDS came to 45.8% -- past most lenders' comfort guideline. Priced on the payment the borrower was actually making, it was never close to a problem.
The numbers
The gap between the two figures sits alongside the broader household debt-service picture across Canada, though this file's fix turned on one borrower's own confirmed payment, not a general rule.
| TDS, on the bureau figure versus the confirmed RAP payment | Amount |
|---|---|
| Purchase price | $335,000 |
| Down payment (10%) | $33,500 |
| Total insured mortgage | $310,846 |
| TDS using the bureau's $310/mo contractual figure | 45.8% |
| TDS using the confirmed $45/mo RAP payment | 41.8% |
| Debt-service basis | Bureau figure | Confirmed RAP payment |
|---|---|---|
| Qualifying payment (25 years) | $2,168 | $2,168 |
| Property tax and heat | $360 | $360 |
| Existing car loan | $230 | $230 |
| Student loan payment | $310 | $45 |
| TDS ÷ $6,700 income | 45.8% | 41.8% |
The 4-point gap between 45.8% and 41.8% is entirely the student loan's own payment figure -- the mortgage side of the file never changed at all.
The solution
A mortgage agent licensed under Ontario’s Mortgage Brokerages, Lenders and Administrators Act treated the bureau's payment figure as a starting point to verify, not a settled fact.
First, had the borrower request a current confirmation letter directly from the National Student Loans Service Centre, showing the actual payment approved under the Repayment Assistance Plan.
Second, compared that confirmed figure against the bureau's own reported minimum, establishing exactly how large the gap was and why it existed.
Third, moved the file to a second lender whose underwriter would use the NSLSC-confirmed payment instead of the bureau's stale contractual figure.
The outcome
The purchase funded insured with GDS at 37.7% and TDS at 41.8%, priced on the payment the borrower was actually making, not the one the bureau happened to display.
Repayment Assistance Plan payments are individually income-tested and reassessed periodically by the National Student Loans Service Centre; the $310 and $45 figures here are illustrative of one file, not a published formula or a fixed amount for every borrower.
What to take from this file
- 01A bureau record can show a Canada Student Loan's original contractual minimum even after the Repayment Assistance Plan has reduced it. The two figures aren't the same thing.
- 02The NSLSC's own confirmation letter is the reliable source for what a borrower is currently obligated to pay. A bureau line item isn't a substitute.
- 03Don't assume a first lender's system checked which payment applies. Many simply pull the bureau's reported minimum without further verification.
- 04A few points of TDS can turn entirely on one debt's correctly confirmed payment. Worth verifying on any file with a student loan close to the ceiling.
- 05RAP payments are individually income-tested and change over time. Get a current confirmation letter for the file, not a figure from a prior year.
