The client
A household in North Bay is buying a $395,000 home at 5% down, qualifying on $8,700/month of combined income. Their bureau file came back clean on a first lender's automated pull -- but the household also carries several buy-now-pay-later instalment plans that never touch a Canadian credit bureau at all.

The problem
A total debt service calculation is only as complete as the debts a lender can actually see -- and Canada's two consumer credit bureaus, Equifax and TransUnion, do not receive standard reporting from most buy-now-pay-later providers the way they do from credit cards and instalment loans.
What a bureau pull cannot see
- ▸Canada's two consumer bureaus do not receive routine reporting from most buy-now-pay-later providers the way they do from credit cards and instalment loans
- ▸The applicant's combined BNPL payments came to $300/month, fully disclosed on the application but invisible to the automated bureau pull
- ▸A first lender's system, reading only the bureau file, would have measured this household's debt service $300/month lighter than its real obligations
Nothing about the BNPL plans was hidden or disputed -- they simply exist in a part of the credit system a mortgage lender's usual pull does not reach.
The numbers
Counting the BNPL payments as an ordinary obligation, the way any other instalment debt is counted, changed the file's total debt service without changing a single fact about the mortgage itself.
| The insured purchase | Amount |
|---|---|
| Base mortgage (95% of purchase price) | $375,250 |
| CMHC premium -- 4.00% in the 90.01-95% LTV band | +$15,010 |
| Total insured mortgage | $390,260 |
| Total debt service | Counting only the bureau | Counting the BNPL plans too |
|---|---|---|
| Mortgage payment at the qualifying rate (6.75%) | $2,673 | $2,673 |
| Property tax | $330 | $330 |
| Heat | $125 | $125 |
| Car loan | $230 | $230 |
| Buy-now-pay-later instalment plans | $0 | $300 |
| Total debt service | 38.6% | 42.0% |
This file's GDS came to 36.0%, and both TDS figures sit comfortably inside CMHC's 44% maximum, so this file was never at risk of failing the ratios. The point was never that 42.0% is a dangerous number -- it's that a lender who only ever sees 38.6% is measuring a household that does not actually exist.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the automated bureau pull as a starting point, not the full picture.
First, asked directly whether the household carried any buy-now-pay-later or retail instalment plans. This is not a question a standard application form always prompts, and a clean bureau pull gives no reason to ask.
Second, obtained the statement or app screen for each BNPL plan. Confirmed the exact monthly payment and remaining balance for every plan, rather than estimating.
Third, added the full $300/month to the qualifying total debt service calculation before submission. Rather than let the file go in on the bureau's incomplete number, priced it on the household's real obligations.
The outcome
The purchase funded insured at 36.0% GDS and 42.0% TDS -- the true number, not the bureau's incomplete one, with every disclosed obligation already accounted for before the mortgage payment even started.
GDS and TDS both sit comfortably inside CMHC's 39% and 44% maximums; this file was never close to either ceiling, with or without the BNPL payments.
What to take from this file
- 01A clean bureau pull is not the same as a clean debt picture. Canada's two credit bureaus do not routinely receive buy-now-pay-later reporting, so a real obligation can sit entirely outside what an automated pull returns.
- 02Ask about BNPL plans directly, on every file. A household has no reason to volunteer a debt that doesn't show up anywhere else, and a standard application doesn't always prompt for it.
- 03Counting a disclosed BNPL obligation in total debt service is prudent practice, not a regulatory requirement. No insurer or regulator publishes a rule requiring it -- it protects the file from a payment shock the bureau alone would never have flagged.
- 04An invisible obligation is a risk to the household after closing, not to the file before it. This purchase cleared comfortably either way, in line with how household debt service ratios typically run across Canada; the value of counting the BNPL payments was avoiding a surprise once the mortgage payment started landing alongside them.

Illustrative in this file — lender-specific, not rules:
- ▸4.75% contract rate — rates move daily; not a quote.
- ▸the $300/mo combined BNPL total — each buy-now-pay-later provider sets its own instalment schedule; there is no published, universal figure.
- ▸treating BNPL obligations as ordinary debt for TDS purposes — no Canadian regulator publishes a rule requiring BNPL plans to be counted; this is prudent lending practice, not a mandated calculation.
