The problem
Before releasing the final draw, the lender required a fresh survey of the completed lot — standard practice once a foundation and structure actually exist to measure against. The surveyor's own field measurements didn't line up with the metes-and-bounds description carried on the property's registered reference plan, filed decades before either the borrower or the lender had anything to do with the land.
What the discrepancy actually was — and wasn't
- ▸This was not a clerical PIN or legal-description typo on the charge itself — that error type gets caught and corrected differently, and had already shown up elsewhere in the file's own title search with no issue
- ▸It was not the new structure encroaching over a boundary — the house itself sat entirely within the measured lot
- ▸It was a genuine mismatch between what the land actually measures today and what a decades-old plan says it measures, the kind of drift that shows up when older plans predate modern survey equipment
Nobody had done anything wrong. The plan was old, the survey was new and more precise, and the two didn't agree — which meant the lender needed the discrepancy resolved, one way or another, before it would fund a mortgage against a legal description it could no longer be certain was accurate.
The numbers
Sizing the construction mortgage itself was routine; the boundary discrepancy was a separate, parallel problem that had nothing to do with the budget.
| Sizing the construction mortgage | Amount |
|---|---|
| Land value | $150,000 |
| Construction budget | +$480,000 |
| Total project cost | $630,000 |
| Total debt service at the take-out mortgage | Figure |
|---|---|
| Construction mortgage at 75% loan-to-cost | $472,500 |
| Payment at the qualifying rate (7.35%), 25 years | $3,412/mo |
| Property tax | $395/mo |
| Heat (lender estimate) | $160/mo |
| Car loan | $300/mo |
| Total debt service | 38.1% |
38.1% left comfortable room on the household's own income once the mortgage converted to a standard take-out, consistent with what national residential construction data shows for an owner-built project of this size. That number was never the risk in this file — the survey was.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the boundary discrepancy as a title question to be resolved against the draw schedule's own deadline, not a reason to let the final draw slip indefinitely.
First, had the surveyor and the lender's own solicitor compare notes directly to confirm the discrepancy was in the old plan's precision, not in anything the surveyor had done on the new one.
Second, weighed the two available fixes against the closing date: depositing a corrected reference plan with the land registry office, which is the permanent fix but can take weeks the draw schedule didn't have, against a title insurance boundary endorsement, which the insurer could issue almost immediately once it reviewed the survey.
Third, took the endorsement to release the final draw on schedule, leaving the borrower free to deposit a corrected plan later, on their own timeline, without that step ever holding up funding.
The outcome
The final draw released on schedule once the title insurer issued the boundary endorsement, insuring the lender's position against the specific discrepancy rather than waiting for a corrected plan to work its way through the land registry office. The borrower kept the option to deposit a new reference plan later, cleaning up the public record permanently without that step ever being a condition of funding.
Nothing about the construction mortgage's own numbers changed. The entire episode ran on a separate track from the budget, the draws and the take-out, exactly as a title problem with no bearing on the borrower's qualification should.
What to take from this file
- 01A survey-versus-reference-plan mismatch is a real, substantive title issue — distinct from a clerical legal-description error and distinct from a structure actually encroaching over a boundary.
- 02Older registered plans can genuinely disagree with a modern, more precise survey. That disagreement doesn't mean anyone made an error; it means the paper is old.
- 03A title insurance boundary endorsement can resolve the discrepancy fast enough to protect a draw schedule, while a corrected reference plan deposit remains available as the permanent fix on the borrower's own timeline.
- 04Keep a title problem and a construction budget on separate tracks. Neither one should be allowed to stall the other unnecessarily.
- 05Get the surveyor and the lender's solicitor talking to each other directly rather than relaying technical findings through the broker.

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%.
- ▸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:
- ▸5.35% contract rate — rates move daily; not a quote.
- ▸the 75% loan-to-cost ceiling — each lender sets its own construction loan-to-cost policy; this is not a universal regulatory figure.
- ▸the TDS figure — this is an uninsured construction take-out, so there is no CMHC ratio ceiling — the number is informational.
