The client
A first-time buyer in Norfolk County, Ontario had steady income and no active debt problems, but three small collections accounts from years earlier — a lapsed cell-phone contract, an old gym membership, a utility final bill — sat unpaid on the credit file, each one small enough to have been forgotten and each one enough, together, to hold the score below CMHC’s 600 minimum for an insured mortgage.

The problem
None of the three collections accounts was disputed, and none was large — together they totalled a few hundred dollars. But an FSRA-licensed Ontario mortgage agent knows that an unpaid collection, however small, can hold a score below the line that matters most for an insured file: CMHC’s minimum credit score of 600.
What was on the file
- ▸A cell-phone contract balance sent to collections after a plan cancellation
- ▸A gym membership cancellation fee, disputed verbally but never resolved in writing
- ▸A final utility bill from a previous address
- ▸Score before cleanup: 585 — 15 points under CMHC’s floor
At 585, this file could not proceed to insurance at all, regardless of income or down payment. Collections accounts like these rarely show up in national delinquency figures — see Canada’s mortgage arrears rate for how rare actual mortgage delinquency is — but a credit bureau treats a small unresolved account exactly like it treats a missed loan payment. The fix was not a ratio adjustment; it was clearing every account, then documenting that each one reported as paid and settled.
The numbers
Once the score cleared, the purchase itself was a standard insured file at the 5% minimum down payment — but a tight one, with little room on GDS, not unlike how tight Canadian households’ overall debt-service ratio has become nationally.
| Structuring the insured purchase | Amount |
|---|---|
| Purchase price | $400,000 |
| Down payment (5% — the minimum at this price) | −$20,000 |
| Base mortgage (95% LTV) | $380,000 |
| CMHC premium — 4.00% in the 90.01–95% LTV band, capitalized | +$15,200 |
| Total insured mortgage | $395,200 |
The contract rate is 4.89%, so the minimum qualifying rate is 6.89%. Monthly payment at that rate is $2,741; at the contract rate it would be $2,274.
| Ratio at the qualifying rate | Figure |
|---|---|
| GDS and TDS — no other debt on the file | 38.7% |
38.7% clears the 39% GDS ceiling by three tenths of a percentage point. With the minimum down payment and no other debt to trim, there was no second lever to pull if the credit score had not cleared — the collections cleanup was the entire margin this file had.
The solution
First, pulled a full credit report before quoting anything. A score below 600 is not something a broker can talk a lender past; it has to change before the file is submitted.
Second, resolved each account with proof, not just payment. The gym membership required a written settlement letter, not just a payment, since the client disputed the original charge; the phone and utility balances were paid in full with confirmation requested in writing from each collector.
Third, waited for the bureau refresh before submitting. Paying a collection does not update the score instantly; the agent confirmed the updated report showed all three accounts as paid or settled before the file went to any lender.
The outcome & the closing math
Approved and funded: insured at 95% LTV, 25-year amortization, on a 5-year fixed term, with the score sitting at 630 by the time the file reached the insurer.
| Cash due at closing (beyond the down payment) | Amount |
|---|---|
| Ontario land transfer tax on $400,000 — 0.5%/1.0%/1.5%/2.0% marginal brackets | $4,475 |
| Legal fees, title insurance & adjustments | varies |
As a first-time buyer, the client also qualified for Ontario's land transfer tax refund of up to $4,000, reducing the net tax actually due at closing to $475.
What to take from this file
- 01A score under CMHC’s 600 floor blocks an insured file outright, regardless of income, down payment, or ratios — fix the score first.
- 02Paying a collection is not the same as clearing it on the bureau. Confirm the refreshed report before submitting.
- 03At the minimum down payment, GDS has almost no slack. Know the exact number before you promise a client the file will pass.
- 04Ontario’s first-time-buyer land transfer tax refund caps at $4,000; above the $368,000 full-coverage threshold, budget the difference in cash.
