The client
A household in Norfolk County switching lenders at renewal on a $320,000 first mortgage, with a First-Time Home Buyer Incentive shared-equity second charge -- now worth $24,000 under CMHC's own repayment formula -- still registered behind it.
New first mortgage
$320,000
Being switched to a new lender
FTHBI shared-equity charge
$24,000
Registered to the Government of Canada at purchase
Current home value
$455,000
Combined income
$8,200/month
The problem
The First-Time Home Buyer Incentive's shared-equity contribution is a genuine second mortgage on title, not a grant. The first lender approached assumed it had to be paid out before a switch could register -- the way an ordinary private second would -- when CMHC's own operational policy instead lets the charge be maintained through a refinance, provided the new first lender agrees and combined loan-to-value stays inside the program's own cap.
What the first lender got backwards
- ▸The Incentive's shared-equity charge is registered behind the first mortgage, just like a private second, but it is not treated the same way at a switch
- ▸CMHC's own program rules let the charge stay in second position through a refinance, as long as the new lender agrees to maintain it there
- ▸The only real constraint is combined loan-to-value -- the new first mortgage plus the Incentive charge cannot exceed 80% of current value
Nobody needed to find $24,000 to pay this out. The program was built to let it ride through a switch, not force a payout every time a borrower renews.
The numbers
The combined-LTV math is what actually determined whether the charge could stay.
| Checking the program's own combined-LTV limit | Amount |
|---|---|
| New first mortgage | $320,000 |
| FTHBI shared-equity charge | $24,000 |
| Combined charges | $344,000 |
| Combined loan-to-value | Figure |
|---|---|
| Combined charges ÷ current home value ($455,000) | 75.6% |
| Program's own combined-LTV cap | 80% |
75.6% sits comfortably inside the program's 80% ceiling, which is exactly what let the new lender agree to register behind the Incentive's existing charge rather than insist on a payout neither the program nor the borrower's equity actually required -- the kind of outcome Canadian mortgage renewal statistics suggest is increasingly common as the 2026 payment-increases-at-renewal wave plays out.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act confirmed the Incentive's own second-ranking-maintenance rule before assuming a payout was necessary.
First, obtained the Incentive's current repayment figure directly from CMHC's program administrator -- a program-calculated amount, not something derivable from price alone.
Second, confirmed the combined loan-to-value of the new first mortgage and the Incentive charge against the program's own 80% cap. At 75.6%, the file was comfortably inside it.
Third, moved the switch to a lender willing to register behind the Incentive's existing charge, rather than the first lender's default assumption of a required payout.
The outcome
The switch closed at 4.75% with the Incentive's shared-equity charge undisturbed in second position, and total debt service settled at 36.7%.
Because this switch is uninsured -- no new insurance event occurs at a lender switch -- CMHC's ratio maximums do not apply directly; the 36.7% figure is informational.
What to take from this file
- 01The First-Time Home Buyer Incentive's shared-equity contribution is a real, registered second mortgage, not a grant -- but it does not have to be paid out at every renewal.
- 02CMHC's own operational policy lets the charge be maintained through a refinance, provided the new lender agrees and combined LTV stays inside the program's cap.
- 03Get the Incentive's current repayment figure from the program administrator directly. It reflects the home's appreciation under a capped formula, not a number a broker can calculate from price alone.
- 04Not every lender will say yes to maintaining the charge. Confirming the rule exists is only useful once a specific lender agrees to work with it.

Illustrative in this file — lender-specific, not rules:
- ▸4.75% contract rate — rates move daily; not a quote.
- ▸the $24,000 current Incentive repayment figure — CMHC's shared-equity formula caps the program's gain or loss at a fixed annual rate on the original Incentive amount; the current figure is program-administered, not independently computable from price alone.
- ▸the TDS figure — this switch is uninsured, so there is no CMHC ratio ceiling -- the number is informational.
