The problem
A Real Property Report at final draw shows the building exactly as constructed, not as planned. On this file, the as-built survey showed the new garage addition encroaching over the rear setback -- a problem created by the completed structure's own footprint, not by anything that existed on the land before construction began.
Why this wasn't caught earlier
- ▸Earlier draws were released against inspected progress, not a full as-built survey -- no survey at that stage would have shown a completed structure's exact footprint
- ▸The encroachment only existed once the garage addition was actually finished in its final position
- ▸The lender's completion condition required a clean as-built survey (or an equivalent title remedy) before the final draw and takeout would fund
The build itself was finished on time and on budget. The survey it triggered at the very end was what held up the last piece of money.
The numbers
The completion mortgage's own math was unaffected by the encroachment; only the timing of the final draw was.
| The completion takeout | Amount |
|---|---|
| As-completed value | $460,000 |
| Base mortgage (90% LTV) | $414,000 |
| CMHC premium (3.10% at 90% LTV) | +$12,834 |
| Total insured mortgage | $426,834 |
| Ratio check at the qualifying rate | Figure |
|---|---|
| Payment at the qualifying rate (6.90%), 25 years | $2,963/mo |
| GDS (payment + $350 tax + $140 heat) ÷ $9,200 income | 37.5% |
| TDS (GDS numerator + $260 car loan) ÷ $9,200 income | 40.4% |
37.5% and 40.4% sit comfortably inside CMHC's 39% GDS and 44% TDS maximums, tracking the kind of financing pattern housing starts data shows across Canadian self-builds. The ratios were never the obstacle on this file -- releasing the final draw was.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the encroachment as a title condition to clear, not a construction defect to fix.
First, confirmed with the lender's solicitor exactly what would satisfy the completion condition -- a clean as-built survey, a municipal minor variance, or a title insurance endorsement, all of which some lenders will accept.
Second, obtained a title insurance encroachment endorsement insuring the lender and the owners against the encroachment, rather than pursuing a municipal minor variance that would have taken weeks longer with no guaranteed outcome.
Third, released the held-back $28,000 the moment the endorsement was in hand, funding the completion takeout without altering the garage's actual footprint at all.
The outcome
The final draw released once the title insurance endorsement was confirmed, and the completion mortgage funded insured at 4.90%, with GDS at 37.5% and TDS at 40.4%.
Both ratios sit comfortably inside CMHC's 39% GDS and 44% TDS maximums; the encroachment affected only the timing of the final draw, never the ratios themselves.
What to take from this file
- 01A final-draw as-built survey can surface a problem no earlier inspection could have caught. An encroachment created by the completed structure's own footprint does not exist until the building is actually finished.
- 02Ask the lender's solicitor early what will satisfy a completion condition like this. Some lenders accept a title insurance endorsement in place of a municipal variance; others do not -- confirm before assuming either path.
- 03A title insurance endorsement is often faster than a municipal minor variance, with a more certain outcome, for a small, already-built encroachment.
- 04Keep the ratio math and the title remedy as two separate questions. This file's GDS and TDS were never in doubt; only the final draw's timing was.

Every regulatory figure in this file traces to one of these primary sources. Client details and anything that varies by lender are illustrative, as flagged below.

- ▸OSFI — Minimum qualifying rate for uninsured mortgages — the minimum qualifying rate — greater of contract rate + 2% or 5.25%.
- ▸CMHC — CMHC Reviews Underwriting Criteria — GDS 39% / TDS 44% maximums and the 600 credit-score floor for insured files.
- ▸Provincial/territorial mortgage-broker legislation fetched directly (bclaws.gov.bc.ca, legisquebec.gouv.qc.ca, fcaa.gov.sk.ca, web2.gov.mb.ca, nslegislature.ca, assembly.nl.ca) plus FCNB's own site for NB and CanLII's index for PE — see notes for per-province method — provincial mortgage regulators and licence titles.
Illustrative in this file — lender-specific, not rules:
- ▸4.90% contract rate — rates move daily; not a quote.
- ▸the $28,000 holdback — each lender sets its own holdback size pending resolution of a title condition; this is this file's own particular, not a standard.
- ▸the title insurance endorsement as the fix — whether an endorsement satisfies a given lender, versus requiring a variance or survey, is a lender-by-lender and municipality-by-municipality judgment call.
