The problem
The buyer's solicitor ran the routine off-title and municipal searches that go with any resale purchase, and the municipality's own permit records turned up an open building permit — issued years earlier for a basement renovation the seller had done, never closed out with the municipality's final inspection.
Why an open permit is a real closing risk
- ▸An open permit means the municipality has no record confirming the finished work actually met the building code, whatever it looks like today
- ▸Closing the permit requires the municipality to schedule and complete a final inspection, which can take weeks or months depending on the office's own backlog
- ▸The seller, who did the renovation, had no particular incentive to chase down an inspection on a home they were about to no longer own
The renovation itself wasn't the concern — the basement had been lived in without incident for years. What the lender needed addressed was the specific, documented risk of an unresolved municipal record, not a general sense that the work was probably fine.
The numbers
The purchase itself qualified in the ordinary way; the open permit was a separate, parallel closing condition that had nothing to do with the buyer's income.
| Sizing the insured purchase | Amount |
|---|---|
| Purchase price | $455,000 |
| Down payment (10%) | $45,500 |
| Base mortgage | $409,500 |
| CMHC premium (3.10%) | $12,694 |
| Insured mortgage | $422,194 |
| Total debt service | Figure |
|---|---|
| Payment at the qualifying rate (7.25%), 25 years | $3,023/mo |
| Property tax | $340/mo |
| Heat (lender estimate) | $130/mo |
| Total debt service | 40.7% |
40.7% cleared CMHC's 44% ceiling with room to spare once the two-year average of T1 and T2 income was applied. Ontario's 8% Retail Sales Tax on the premium, roughly $1,016, was paid in cash at closing rather than added to the mortgage.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act let the income file and the title file run on entirely separate tracks, since neither one had any bearing on the other.
First, qualified the buyer in the ordinary way, averaging two full years of T1/T2 self-employed income from an established, unchanged business — nothing about the file's income side was unusual.
Second, had the solicitor confirm the open permit's exact status directly with the municipality rather than relying on the seller's own assurance that the work was fine.
Third, obtained a title insurance endorsement covering the open-permit risk, insuring the lender and the buyer against the possibility the municipality later required remedial work, so closing didn't have to wait on an inspection nobody could actually schedule.
The outcome
The purchase closed on the scheduled date. The title insurance endorsement covered the specific risk the open permit represented, so neither the buyer nor the lender had to wait on the municipality's own inspection backlog to get a mortgage funded on a home the buyer had every intention of keeping for years.
The buyer could pursue closing out the permit with the municipality afterward, on their own schedule, entirely separate from the purchase itself — exactly the kind of administrative cleanup that doesn't need to hold up a closing when it's properly insured over.
What to take from this file
- 01An open building permit is a routine off-title search finding, not a reason to assume the underlying work is unsafe or non-compliant.
- 02Title insurance can cover the specific risk of an open permit, letting a closing proceed without waiting on a municipal inspection schedule nobody controls.
- 03A self-employed buyer's income qualification and a title issue on the property are independent problems. Don't let one hold up progress on the other.
- 04Confirm an open permit's status directly with the municipality, not through the seller, before deciding how to handle it.
- 05Ontario's RST on a default-insurance premium is paid in cash at closing and cannot be added to the mortgage — budget for it separately.
