The client
A homeowner in the Kawartha Lakes market borrowed $520,000 in 2019 at the bottom of a low-rate cycle, on a 5-year fixed at 2.89% over a 25-year amortization. The mortgage renewed once in 2024, into a materially higher-rate environment, and matured again in 2026 — two renewal cycles inside the industry-wide pattern documented in Canadian mortgage renewal statistics. He wanted one number: after two renewals, was he actually worse off than in 2019, and by how much?

The problem
This is the textbook shape of the 2026 renewal wave: a mortgage signed at a generational low is maturing into a materially different rate environment, not once but twice, and each renewal compounds on the balance the last one left behind.
What each renewal actually did
- ▸Original 2019 payment: $2,432/mo
- ▸2024 renewal payment, at 5.89% on the amortized-down balance: $3,131/mo — a $699 jump
- ▸2026 renewal payment, at 5.29%: $2,996/mo — $135 of relief from the 2024 peak, but still $564 above 2019
The borrower's instinct was to compare 2024 to 2026 and call the story "rates coming down." That is true only against the 2024 peak. Against the number he actually started with in 2019, he is still paying materially more — the second renewal softened the shock, it did not reverse it.
The numbers
Because the borrower stayed with the same lender at both renewals, no fresh stress test applied at either point — a straight renewal with the incumbent lender is not the switch or refinance event the qualifying rate governs. The whole exercise is amortization math: what does the balance do, and what does each new rate do to the payment on what's left.
| The loan across both renewal cycles | Amount |
|---|---|
| Original monthly payment (2.89%, 25-year amortization) | $2,432 |
| Balance remaining after 5 years / 60 payments | $443,525 |
| 2024 renewal payment (5.89%, 20-year remaining amortization) | $3,131 |
| Balance remaining after 24 more payments | $418,628 |
| 2026 renewal payment (5.29%, 18-year remaining amortization) | $2,996 |
Payments computed the Canadian way — rate compounded semi-annually, paid monthly — on each renewal's actual remaining amortization, and rounded to the nearest dollar.
Reading the two jumps together
| Comparison | Amount |
|---|---|
| 2024 renewal vs. original 2019 payment | +$699/mo |
| 2026 renewal vs. 2024 peak | −$135/mo |
| 2026 renewal vs. original 2019 payment | +$564/mo |
The payment increases at renewal most industry commentary tracks compare one renewal to the one before it. For a borrower on a short 2024 term, the number that actually matters is the compounded change from where they started — and that number never fully unwinds just because the second renewal came in lower than the first.
The solution
An FSRA-licensed Ontario mortgage agent walked the client through both renewal cycles side by side rather than letting the 2024-to-2026 comparison stand alone, because that comparison alone made the situation look better than it was.
With no switch or refinance in the picture, there was no lender to shop and no stress test to price — the value the broker added here was purely in the reporting: showing the client the real, compounded number so future budgeting and any refinance decision down the road starts from an accurate baseline, not a partial one.
The broker also flagged, for context, that a switch to a different lender at either renewal would have required clearing OSFI's minimum qualifying rate — the greater of the new contract rate plus 2% or 5.25% — since this is an uninsured mortgage. Staying with the incumbent lender avoided that test at both points, which is exactly why the file never needed a fresh income review.
That trade-off is worth naming explicitly: the household never had to prove its income could carry either new rate, but it also never had the chance to competitively shop either renewal against the wider market. For a borrower whose income or credit picture might not have supported a fresh qualification, that is a real advantage of staying put rather than a missed opportunity.
The outcome
The client renewed with the incumbent lender both times, with no requalification event at either renewal. The 2026 payment of $2,996 is $564 above where the mortgage started in 2019 — a real and permanent increase to the household's carrying cost, correctly identified and budgeted rather than mistaken for a return to normal because the second jump was smaller than the first.
What to take from this file
- 01Compare a payment to its origin, not just to the renewal before it. A smaller second jump can still leave a household well above where they started.
- 02A straight renewal with the incumbent lender is not a stress-test event. That only attaches to a switch or a refinance — know the difference before quoting a client a qualifying rate they will never actually face.
- 03Amortization keeps working in the client's favour even through payment shock. The remaining amortization shrank from 25 to 20 to 18 years across the two renewals, which is part of why the second jump was smaller than the first.
- 04Report the compounded number, not just the latest one. It is the more useful figure for a client's forward budgeting, even when it is the less flattering one to deliver.
