The client
A buyer in Tillsonburg used a $372,000 purchase-plus-improvements mortgage to fund a $28,000 wheelchair-accessibility retrofit -- widened doorways, a roll-in shower, a no-step entry -- with no secondary suite and no rental income anywhere in the file.
Purchase price
$372,000, Tillsonburg

$6,000
Applied for, not yet authorized -- not counted at closing
Buyer's income
$7,900/month
The problem
March of Dimes Canada's Home and Vehicle Modification Program, funded by the Ontario Ministry for Seniors and Accessibility, will not reimburse a single dollar spent before its own authorization comes through -- and it offers no guarantee of funding at all, even for a complete application.
What the buyer had assumed
- ▸Budgeted the retrofit around receiving $6,000 through HVMP, planning a smaller holdback
- ▸HVMP's own rules bar reimbursement for any cost incurred before its own authorization is issued
- ▸Nothing about HVMP funding is guaranteed -- approval depends on available program dollars, not just eligibility
The buyer had priced the retrofit as though the grant were already money in hand. It was an application, not a commitment.
The numbers
Financing the retrofit's full cost, with no grant offset assumed, is the only version of this file that did not depend on a decision nobody could guarantee.
| Financing the retrofit in full, without the grant | Amount |
|---|---|
| As-improved lending value (purchase + full retrofit) | $400,000 |
| CMHC premium (3.10% at 90% LTV) | +$11,160 |
| Total insured mortgage | $371,160 |
| Total debt service | Figure |
|---|---|
| Payment at the qualifying rate (6.90%), 25 years | $2,577/mo |
| Property tax | $315/mo |
| Heat | $120/mo |
| Car loan | $210/mo |
| Total debt service | 40.8% |
Financing the full $28,000 retrofit brought the as-improved lending value to $400,000 -- $6,000 above the $394,000 the buyer had originally budgeted around while still counting the pending grant. 40.8% clears comfortably inside CMHC's 44% ceiling, consistent with the pace of residential construction investment in smaller Ontario markets. If HVMP later approves and reimburses, that money simply reduces what the buyer effectively spent -- it was never part of this closing's own math.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act sized the purchase-plus-improvements holdback to what the retrofit actually costs, not what a pending application might someday provide.
First, confirmed HVMP's own no-reimbursement-before-authorization rule directly -- there was no version of this file where the $6,000 could be counted as available at closing.
Second, sized the holdback to the retrofit's full $28,000 cost, with no grant offset assumed anywhere in the mortgage math.
Third, structured the draw schedule against inspected, completed work, the same as any purchase-plus-improvements file, keeping the HVMP application's own timeline entirely separate from the mortgage's.
The outcome
The purchase funded insured at 40.8% total debt service, with the accessibility retrofit fully financed and the HVMP application left to resolve on its own timeline.
Because this file is CMHC-insured, the 40.8% TDS figure is measured against the real 44% ceiling and the 38.1% GDS figure against the real 39% ceiling; both clear with real margin.
What to take from this file
- 01A pending, non-guaranteed grant is not funds available at closing. HVMP's own rules bar reimbursing costs incurred before its authorization -- size the financing as though the grant might never arrive.
- 02A reimbursement-based program creates a timing gap a mortgage holdback has to bridge, not close. The two run on entirely separate timelines.
- 03An accessibility retrofit does not need a rental unit or future income to justify a purchase-plus-improvements structure. The program finances the improvement itself, whatever it is being built for.
- 04If a later reimbursement does arrive, treat it as reducing the buyer's own net cost, not as a mortgage repayment or an input to the original math.

Illustrative in this file — lender-specific, not rules:
- ▸4.90% contract rate — rates move daily; not a quote.
- ▸the $6,000 HVMP figure — the program itself does not guarantee any funding amount; this reflects what this family applied for, not a published entitlement.
