Jenna Kowalski was standing in her kitchen in Saskatoon on a Wednesday night in April, barefoot on a cold tile floor, reading a renewal letter from her bank for the third time. Her five-year fixed was up in sixty-one days. The number on the page was 5.84%. The number she had been paying since April 2021 was 1.89%.
She poured a glass of wine she did not really want and did the math on the back of a Costco receipt.
Her monthly payment, on a $412,000 mortgage amortized over the remaining twenty years, was about to go from $2,068 to $2,906. Eight hundred and thirty-eight dollars a month. Ten thousand and fifty-six dollars a year, after tax, out of a nursing salary that had gone up maybe nine percent over the same five years.
She did what most people do in that moment. She got angry at the bank.
That is the wrong target, and this column is about why.
The Number You Are Comparing To Is a Ghost
There is a specific trap waiting for every Canadian renewing a mortgage in 2026, and it has nothing to do with the bank. It has to do with the number in your head.
The number in Jenna's head is 1.89%. That number was real. She signed it. She paid it for five years. Her whole financial life — the Hyundai Tucson in the driveway, the summer trip to Vancouver Island, the extra $300 a month into her TFSA — was built around it.
But 1.89% was not a normal rate. It was the cheapest five-year money Canadian households have ever been offered, by a margin so wide it has no historical peer. The Bank of Canada overnight rate sat at 0.25% for most of 2020 and 2021. The five-year Government of Canada bond — the benchmark fixed mortgages are priced off — traded under 1% for almost eighteen months. Lenders were tripping over each other to put mortgages on their books, and they were doing it at spreads they would never repeat.
If you anchor to 1.89%, every renewal letter in 2026 looks like a robbery.
If you anchor to the forty-year average of a Canadian five-year fixed — somewhere north of 6.5%, depending on which dataset you trust — the 5.84% on Jenna's letter looks like a gift.
Neither anchor is the right one. The right anchor is what the rate should be today, given where the BoC sits, where the bond market sits, and what lenders are actually willing to do. And that is a number you can build yourself in about four minutes.
Building the Rate From the Ground Up
Here is how a fixed mortgage gets priced, in the order a treasury desk actually thinks about it.
Start with the five-year Government of Canada bond. As of this week it is trading around the high 2s. Call it 2.85%.
Add the lender's funding spread. For an A-lender writing insured or low-ratio conventional paper, that is typically 150 to 200 basis points — a basis point is one one-hundredth of a percentage point, so 150 bps is 1.50%. Call it 175 bps.
Add the lender's margin. Another 100 to 125 bps, depending on the channel, the broker deal, and how badly the bank wants the book. Call it 110 bps.
2.85 + 1.75 + 1.10 = 5.70%.
That is roughly where a discounted five-year fixed should live this week. Canadian Finance Hub is showing 6.09% as the posted five-year fixed on its front page this morning. Posted is not discounted — the discounted number a broker can actually put in front of you is usually 30 to 50 bps lower. Call it 5.59% to 5.79%.
Jenna's bank offered her 5.84%. She is being offered a number that is about fifteen basis points worse than what the broker channel would hand her on a Tuesday. Fifteen basis points on a $412,000 mortgage is not nothing — over five years it is roughly $3,100 in interest. But it is also not the story. The story is that the entire five-and-a-half-percent regime is the regime, and the bank did not invent it to punish her.
Once you build the rate from the ground up, the renewal letter stops feeling like an ambush. It starts feeling like a weather report.
The Working-Capital Shock Most People Miss
The monthly payment is the thing everybody focuses on. It is not actually the most dangerous number in a renewal.
The dangerous number is the amortization math. At 1.89%, the first payment on Jenna's original $450,000 mortgage was splitting roughly 35% interest, 65% principal. At 5.84%, on her remaining $412,000 balance over twenty years, the first payment after renewal splits roughly 67% interest, 33% principal. Her monthly cheque is going up by $838, and the share of that cheque that actually buys her a piece of the house is collapsing.
In plain terms: she is paying more and owning less, every month, for the first two years of the new term. Her equity build slows to a crawl.
This is the part the renewal letter does not spell out. It also happens to be the part that matters if she might need to break the mortgage — for a move, a job change, a separation, a refinance to consolidate a HELOC. The break penalty on a fixed mortgage is the greater of three months' interest or the interest rate differential. On a 5.84% mortgage three years into a five-year term, with rates flat or lower, the IRD calculation can quietly produce a penalty north of $18,000. Most people have no idea until the discharge statement lands.
Name the trap: the seductive move right now is to grab the longest fixed term you can find, because you are scared the renewal rate could go higher in two years. That fear is real. But locking yourself into a five-year fixed when there is any meaningful chance you will break it is the most expensive thing a household can do in a high-rate regime, because the IRD math gets very ugly very fast. The cheap-looking move is the expensive one.
What Jenna Should Actually Do
You can run the decision as a grid. Three realistic options, same $412,000 balance, twenty-year remaining amortization, five-year horizon.
| Option | Rate | Monthly payment | 5-yr interest paid | Flexibility |
|---|---|---|---|---|
| 5-yr fixed, bank's offer | 5.84% | $2,906 | $109,700 | Low — ugly IRD |
| 5-yr fixed, broker-sourced | 5.59% | $2,845 | $104,800 | Low — ugly IRD |
| 3-yr fixed, broker-sourced | 5.29% | $2,773 | $63,400 over 3 yrs | Higher — renews into whatever 2029 looks like |
| 5-yr variable, prime −0.90 | 3.55% | $2,390 | $71,800 if rates hold | Highest — three months' interest penalty only |
Numbers in the table assume the same $412,000 balance and twenty-year amortization. They ignore property tax, insurance, and any lump-sum prepayments. Pull actual quotes from a broker the week you sign.
The one number that matters most to her decision: the variable-rate option saves her $516 a month against the bank's fixed offer, today, on the current prime of 4.45%. If she parks that $516 a month into the same TFSA she has been feeding since 2021, at the top HISA rate on Canadian Finance Hub's front page today — 3.25% — she builds a $33,500 liquid cushion over five years. That cushion is the actual hedge against rates going the wrong way. Not a longer fixed term. A pile of cash she controls.
That is not a universal answer. A household with variable income, a thin emergency fund, or a partner who cannot sleep when the payment changes should not be in a variable. But Jenna is a full-time nurse with job security that most Canadians would trade their car for, and she has six months of expenses in an EQ Bank account already. She can wear the risk. Her bank is selling her insurance she does not need, at a price that assumes she will never shop.
The Reframe
The renewal letter is not a verdict. It is an opening offer from a counterparty who knows most people will not negotiate, will not shop, and will not do the arithmetic. Every one of those three defaults costs real money. The arithmetic is the cheapest of the three to fix — it takes a receipt and a pen.
The number in your head from 2021 is a ghost. The number on the letter is a draft. The number that matters is the one you build yourself, from the bond market up, and then carry into the broker's office with your shoulders squared.
Jenna has sixty-one days. That is enough time to get three real quotes, run the variable-versus-fixed math on her own kitchen table, and walk into her branch with a printed competing offer. The bank will move. They almost always do.
Next week we are going to do the same exercise on a number far fewer Canadians have looked at honestly: the real annual cost of the card in your wallet, once you subtract the rewards you never actually redeem.
