## How this bi-weekly payment is produced
Ontario high-ratio purchases at this band still clear the insured-price cap, so the engine adds a default-insurance premium to principal before it amortizes. Bi-weekly is not the accelerated schedule: it spreads the same annual cost across twenty-six visits instead of twelve, which slightly changes the periodic rate but does not donate an extra monthly equivalent to principal. The split on the first debit is almost all interest because almost none of the loan has been retired. Land-transfer tax in the rest of the province is a closing-cash problem, not a payment-engine problem — it never enters this principal.

### Periodic rate
i = (1 + r/2)^(2/n) − 1. At 4.79% monthly, i = 0.395241%.

### Amount amortized
$350,000 − $17,500 = $332,500; insurance $13,300; total $345,800.

### Annuity
$908.29 bi-weekly over 25 years. First period: $630.13 interest, $278.16 principal. Year-five balance $305,039.

## What this band means
This is the high-ratio starter band in Ontario. The legal minimum down payment is still five percent of the whole price, so the loan-to-value sits at the top of the insured stack and a premium is capitalized rather than written as a cheque. Buyers here are usually income-bound, not equity-rich: the payment has to clear a payroll cycle, which is why the bi-weekly schedule shows up so often in this slice. Closing cash is a separate fight — provincial land transfer tax, legal fees, and the provincial sales tax on the insurance premium in this province — even when the down payment itself looks small. A thirty-year amortization is not assumed here; this page holds the standard twenty-five-year insured clock so the payment is comparable to what most high-ratio commitments actually look like on a non-first-time file.

Ontario property tax and heating sit on top of this payment in the qualification math even though they are not in the $908.29 figure itself. If the same buyer instead paid monthly, the annual cost would be nearly identical; the bi-weekly rhythm is a cash-flow choice, not a shortcut off the amortization.

## Local context
Think of Kitchener, London, Guelph, Cambridge, or a Hamilton starter detached: payroll hits fortnightly, the down payment was scraped from an FHSA, and the lawyer’s trust account is already earmarked for provincial levy plus PST on the premium. CMHC, Sagen, or Canada Guaranty is a back-office fact, not a brand the buyer shops. The bi-weekly PAD is set to land the day after payday so NSF risk stays off the commitment. Waterloo Region shift work, a scraped First Home Savings Account, and a trusteed premium-PST cheque are the origination story. Hespeler, Preston, Blair, Doon, Elmira, Fergus, and the millrace towns around Cambridge are the geography. This is not a Toronto municipal-tax file and not a thirty-year first-time stretch.

## Sensitivity
A one-point move in the quoted rate changes this bi-weekly debit more than stretching the amortization does, because the loan is small enough that extra years buy little relief and extra rate costs a visible slice of a starter payroll. Crossing the half-million purchase step would change the minimum down-payment recipe itself — five percent of the first slice, ten percent of the rest — which is a different engine than a rate tick.

- Quoted rate 5.79%: $1,000.01 (+$91.72 per payment)
- Quoted rate 3.79%: $820.77 (−$87.52 per payment)
- 30-year amortization: $830.98 (−$77.31 per payment)

## FAQs
### Is a $350,000 Ontario mortgage still insurable with five percent down?
Yes. The purchase sits well below the $1,500,000 insured-price cap, so a five-percent down payment is legal and the loan is high-ratio. The engine capitalizes a default-insurance premium of $13,300 into the amount amortized. You still need cash at closing for land transfer tax and for the provincial sales tax on that premium.

### Does paying bi-weekly on this $350,000 loan shorten the amortization?
Not on the plain bi-weekly schedule used here. The annual cost is split across twenty-six payments instead of twelve, so each debit is $908.29 and the loan still runs 25 years. The accelerated version — half a monthly payment, twenty-six times — would donate an extra monthly equivalent to principal. Ask which schedule the lender is actually booking.

### How much of the first bi-weekly payment on this $350,000 loan is interest?
$630.13 of the first $908.29 debit is interest; $278.16 reduces principal. That split is a function of the 4.79% quote and the still-untouched balance, not of the lender. It tilts toward principal only as the balance falls.
