The client
A homeowner in Sorel-Tracy carried a $219,000 first mortgage and a $49,000 private hypothèque (second mortgage), both to be consolidated into one new A-lender refinance.
First mortgage balance
$219,000
4.50%, 17 years remaining
Private hypothèque balance
$49,000
9.25% interest-only; registered against a since-renumbered cadastral lot
Combined income
$6,800/month
Other debt
$220/mo car loan
The problem
Quebec's cadastral reform (rénovation cadastrale) has, sector by sector, subdivided and renumbered lots across the province over the years -- and this private second mortgage's hypothèque had been registered against the old lot number years before that particular sector's renumbering took effect.
What the payout couldn't clear
- ▸The hypothèque's registered legal description named a cadastral lot number that no longer matched the current cadastre
- ▸A notarial quittance for the payout has to register against the property's current lot number, not a superseded one
- ▸Nobody had updated the hypothèque's own registration when the sector's renumbering took effect years earlier
The lot itself hadn't moved. The number the hypothèque was registered against no longer described it.
The numbers
Once the correcting act was in place, consolidating the first mortgage and the private hypothèque into one new balance was straightforward arithmetic.
| Consolidating the first and the second | Amount |
|---|---|
| First mortgage balance | $219,000 |
| Private hypothèque balance | $49,000 |
| New consolidated balance | $268,000 |
| Total debt service | Before (both mortgages) | After (consolidated) |
|---|---|---|
| Mortgage payment | $1,533 | $1,877 |
| Property tax + heat | $380 | $380 |
| Private hypothèque, interest-only | $378 | -- |
| Car loan | $220 | $220 |
| Total debt service | 36.9% | 36.4% |
36.9% moving to 36.4% is a modest improvement next to the real issue in this file: a hypothèque registered against a superseded lot number cannot be discharged against the property's current cadastral designation, whatever the ratios say -- a registration gap distinct from the payment problems tracked in mortgage arrears data.
The solution
A courtier hypothécaire licensed under Quebec's Act respecting the distribution of financial products and services treated the registration mismatch as a title question for the notary to resolve, not a reason to delay the consolidation indefinitely.
First, confirmed directly with the Bureau de la publicité des droits which cadastral sector renumbering applied and when it took effect, tracing the old lot number forward to its current designation.
Second, had the notary prepare and register a correcting act (acte de correction) formally tying the hypothèque's old lot number to the current one, a step distinct from -- and a precondition to -- registering the discharge itself.
Third, registered the quittance against the correct, current lot only once the correcting act was confirmed on title, before allowing the consolidation to fund.
The outcome
The refinance closed at 5.00%, the hypothèque discharged cleanly against the current cadastral lot, and total debt service settled at 36.4%.
Because this file is uninsured, CMHC's ratio maximums do not apply directly; the 36.9% and 36.4% figures are informational, showing exactly what the consolidation itself changed.
What to take from this file
- 01A hypothèque's legal description is only as good as the cadastral lot number it names. Quebec's cadastral reform has renumbered lots sector by sector for years; confirm whether a specific lot was affected before assuming an old registration still matches the current cadastre.
- 02A correcting act is a distinct step from the quittance itself, and comes first. A notary cannot register a discharge against a lot number the current cadastre no longer recognizes.
- 03The Bureau de la publicité des droits can confirm a sector's renumbering and its effective date directly. That confirmation, not the original hypothèque's own paperwork, is the reliable source.
- 04This kind of file is a registration-accuracy problem with ordinary consolidation arithmetic underneath it. Once the correcting act is registered, the numbers are no different from any other private hypothèque payout.

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:
- ▸9.25% / 5.00% rates — rates move daily; neither is a quote.
- ▸the cadastral renumbering itself — not every lot has been affected by Quebec's cadastral reform; whether and when a given lot was renumbered depends on that specific reform sector's own timeline.
- ▸the TDS figures — this file is uninsured, so there is no CMHC ratio ceiling -- the numbers are informational.
