The client
First-time buyers purchasing a new production home on a lot inside a registered plan of subdivision in Hamilton. Their own insured mortgage was fully approved and rate-held well ahead of the builder's stated completion date.

$682,006 insured, 90% LTV
Developer financing
One blanket construction mortgage covering the whole subdivision
The problem
The buyer's own file was never the issue -- income, credit and the insured commitment were all in order weeks before the builder's completion date. What held the closing was a step the buyer's lender couldn't complete on its own: registering the new purchase mortgage in first position on a lot still legally tied to the developer's financing.
Why one lot can't just close on its own
- ▸Under the Planning Act, section 50(3), land within a registered plan of subdivision can be conveyed and mortgaged lot by lot -- that's the whole reason a registered plan of subdivision exists as an exemption from the Act's general subdivision-control rule
- ▸But the developer typically finances the entire subdivision under one blanket construction mortgage, registered against every lot as a single debt
- ▸That blanket mortgage's own release clause lets the developer's construction lender discharge one lot at a time as units sell and close, at an agreed release price or formula built into the loan from the start
- ▸Until that lot-specific partial discharge is registered, the developer's construction charge still sits on title ahead of anything new -- the buyer's insured purchase mortgage cannot register in first position around it
The buyer's lawyer confirmed the lot was properly created within the registered plan -- there was no defect in how the parcel itself came to exist, the kind of problem a decades-old severance can leave behind. The gap here was current and administrative: the developer's construction lender simply hadn't yet processed this specific lot's release under its own blanket mortgage.
The numbers
This is an insured purchase mortgage; the math below is the buyer's own sizing, unaffected by the release delay -- the delay was procedural, not financial.
| The purchase | Amount |
|---|---|
| Purchase price | $735,000 |
| Down payment (10%) | $73,500 |
| Base mortgage before premium | $661,500 |
| CMHC premium (90% LTV, 3.10% band) | $20,506 |
| Insured mortgage | $682,006 |
Sizing and ratios
| Mortgage math | Figure |
|---|---|
| Minimum qualifying rate — greater of contract + 2% and 5.25% | 7.44% |
| Monthly payment at the qualifying rate | $4,964 |
| Monthly payment at the 5.44% contract rate | $4,139 |
| GDS (qualifying payment + $460 tax + $170 heat) ÷ income | 37.8% |
| TDS (housing + $310 other debt) ÷ income | 39.9% |
Ontario land transfer tax
None of this touched the buyer's own closing costs -- land transfer tax on the $735,000 purchase (Hamilton carries no municipal MLTT on top of the provincial brackets) came to $11,175 regardless of when the release itself landed.

| LTT on $735,000 (Hamilton, no municipal MLTT) | $11,175 |
The solution
The mortgage agent's role here wasn't fixing the buyer's file -- it was tracking a process outside the buyer's control and keeping the closing date realistic once the release's own timeline became clear.
Once the release date was confirmed, the rest of the closing was routine -- the buyer's own mortgage had been ready to fund since the day it was approved.
The outcome
The developer's construction lender registered the partial discharge for this lot twenty-two days after the builder's original completion date. The buyer's mortgage funded at $682,006, 90% LTV, on a five-year fixed at 5.44%, qualifying payment $4,964, GDS 37.8% and TDS 39.9% -- unchanged from the original approval, closing three weeks later than planned.
What to take from this file
- 01A registered plan of subdivision lets individual lots be conveyed and mortgaged under Planning Act section 50(3) -- but the developer's own blanket construction financing still has to release each lot before a buyer's new mortgage can register ahead of it.
- 02A blanket construction mortgage's release clause, not the buyer's file, sets the real closing timeline on a production home inside an active subdivision -- confirm where a specific lot sits in that queue rather than assuming the builder's stated date controls it.
- 03Rule out a title-creation defect before assuming a release delay. A registered-plan lot with a clean root of title is a different, faster problem than a decades-old severance needing correction.
- 04Protect the buyer's rate hold and approval validity against the release timeline, not just the builder's stated completion date. The mortgage being ready to fund doesn't help if the commitment expires first.
