The client
A household self-building on land they already own in Estevan, Saskatchewan, with a $295,000 total project value once complete and combined income of $7,600/month. The construction mortgage itself was straightforward — what stalled the file was insurance, not underwriting.

Lapsed builder's-risk policy
Between the third and fourth draws
The problem
A standard homeowner's insurance policy is written for an occupied, finished home — it doesn't cover an unoccupied construction site. Lenders instead require a course-of-construction (builder's-risk) policy, kept continuously in force with the lender named as loss payee, for the entire build.
Where the coverage actually broke down
- ▸The household's short-term liability-only policy covered the early stages of the build
- ▸That policy lapsed between the third and fourth draws, with no course-of-construction replacement in place
- ▸The lender's draw conditions require continuous coverage throughout the build, not just a policy at completion — the fourth draw would not release without it
Nothing about the household's income, credit or the project's own numbers was ever in question. The insured structure itself — the mortgage, the ratios, the premium — was sound from day one. The gap was entirely about whether the correct insurance was continuously in force, and for several weeks it wasn't.
The numbers
Structuring the loan confirmed what the file review already suggested: this was never a ratio problem.
| The insured construction mortgage | Amount |
|---|---|
| Total project value | $295,000 |
| Down payment (5%, the minimum at this price) | −$14,750 |
| Base mortgage | $280,250 |
| CMHC premium at 4.0% (90.01–95% LTV band) | +$11,210 |
| Total insured mortgage | $291,460 |
| Ratio check at the qualifying rate | Figure |
|---|---|
| Minimum qualifying rate on a 4.75% contract rate | 6.75% |
| Payment at the qualifying rate, 25 years | $1,997/mo |
| GDS (payment + $240 tax + $115 heat) ÷ $7,600 income | 30.9% |
| TDS (GDS numerator + $260 car loan) ÷ $7,600 income | 34.4% |
30.9% and 34.4% sit well inside CMHC's 39% GDS and 44% TDS maximums — confirming that the insurance gap, not the file's underlying numbers, was the single point of failure holding up the fourth draw.
The solution
A mortgage broker licensed under Saskatchewan's Financial and Consumer Affairs Authority (FCAA) treated the insurance gap as the file's only real problem and worked it directly.
First, confirmed exactly when the coverage lapsed. The short-term liability-only policy had expired between the third and fourth draws, leaving several weeks of the build with no course-of-construction protection at all.
Second, placed a proper course-of-construction policy, with the household's insurer agreeing to backdate coverage to the start of the build where the underlying risk record allowed it, and naming the lender as loss payee going forward.
Third, submitted the new policy's confirmation directly against the lender's draw conditions, closing the exact gap those conditions existed to catch.
It would have been possible to argue that no loss had actually occurred during the lapse and ask the lender to waive the requirement. That path exists, but it asks a lender to accept undocumented risk retroactively; placing the correct policy, even after the fact, answered the draw condition on its own terms instead of arguing around it.
The outcome
With continuous coverage confirmed and the lender named as loss payee, the fourth draw released on schedule. GDS and TDS were never re-argued, because they were never the issue.
Saskatchewan's own PST on default-insurance premiums applies to this file's $11,210 premium at 6%, payable in cash and not addable to the mortgage — a separate, ordinary closing cost unrelated to the insurance gap that actually held up the draw. It is exactly the kind of file that shows up in residential construction investment in Canada without any of that activity showing up in the household's own credit or income.
What to take from this file
- 01Course-of-construction insurance is a lender condition on every draw, not a one-time box to check at the start. A lapse mid-build can stop a draw as completely as a shortfall in money.
- 02A standard homeowner's policy does not cover an unoccupied construction site. Confirm the specific course-of-construction product is in force, not just that some policy exists.
- 03Diagnose before assuming a ratio problem. This file's income and credit were fine throughout; confirming that early focused the whole fix on the actual obstacle.
- 04Ask whether an insurer will backdate coverage before assuming a lapse is unfixable. Not every insurer will, but some will where the underlying risk record supports it.
- 05Build insurance continuity checks into every draw request, not just the first one. A policy that was correct in month one can lapse by month four without anyone noticing until a draw is held.
