Mortgage Renewal Shock in 2026: What 1.15 Million Canadians Are Facing

Renewal watch, September 20, 2026. Mortgage renewal shock is no longer a forecast in Canada — it is arithmetic, and this year it lands on about 1.15 million households. CMHC counts roughly 1.15 million Canadian mortgages maturing in 2026, on top of the roughly 1.5 million that had already renewed going into the year. Borrowers rolling off 2020 and 2021 fixed terms priced between 2.0% and 2.99% are signing new ones two to three percentage points higher. On a $600,000 mortgage taken in 2021 at 1.99%, that is the difference between $2,537.81 a month and $3,046.84.

Below: the math on a $400,000, a $600,000 and an $800,000 mortgage, why variable holders face a far smaller jump, why waiting for relief is a weak plan, and which levers actually work.

Mortgage renewal 2026: the scale of the wave

Together those CMHC figures mean roughly 2.65 million Canadian mortgages will have renewed across 2025 and 2026. The cohort facing real mortgage renewal shock is specific: fixed terms signed in 2020 and 2021, when insured five-year money went for 2.0% to 2.99%, maturing into a market where the best five-year fixed insured rate sits near 4.04% and most borrowers are quoted 4.39% to 4.49%.

The frustrating part is that the Bank of Canada has not moved: the policy rate has been 2.25% since October 2025, held through seven consecutive decisions, most recently September 2, 2026. Fixed rates rose anyway, because mortgage renewal rates on fixed terms track the bond market rather than the overnight rate — the five-year Government of Canada yield is near 3.6%, its highest since 2024, and fixed rates have climbed roughly 0.50%, as covered in Rate Alert: Fixed Mortgage Rates Are Rising in Canada. Your renewal is priced by the bond market, not by a central bank you can wait out.

Mortgage renewal shock in dollars: three worked examples

Take the case that describes most of this year's cohort: a $600,000 mortgage from 2021 at 1.99% fixed on a 25-year amortization, five years of payments, no lump sums, renewing into the remaining 20 years. All figures use the Canadian semi-annual compounding convention and a month-by-month amortization, so the balances are real, not rounded.

Original mortgage (2021, 1.99%, 25-yr)	Payment then	Balance after 5 years	New payment at 4.04%	New payment at 4.49%	Increase at 4.49%
$400,000	$1,691.88	$335,010	$2,031.23	$2,110.15	+$418/mo · +$5,019/yr
$600,000	$2,537.81	$502,516	$3,046.84	$3,165.23	+$627/mo · +$7,529/yr
$800,000	$3,383.75	$670,021	$4,062.46	$4,220.30	+$837/mo · +$10,039/yr

At the best insured rate of 4.04%, the increases are $339.35, $509.03 and $678.71 a month — $4,072, $6,108 and $8,144 a year. At 4.49%, the number on most renewal letters, they become $418.28, $627.41 and $836.55. The proportional renewal payment increase is identical in all three cases: 20.1% at 4.04% and 24.7% at 4.49%. The dollar pain scales with your balance; the percentage hit does not.

Two things surprise people. First, how little principal five cheap years retired: $152,269 went in and only $97,485 came off the balance, with $54,784 going to interest. Second, the shorter remaining amortization works against you — compressing $502,516 into 20 years instead of 25 lifts the payment before the new rate is applied.

Over the next five years that borrower pays about $92,025 in interest at 4.04%, against roughly $44,639 had 1.99% carried forward — the payment shock in one number: about $47,400 of extra interest.

Why variable-rate holders face a much smaller jump

Mortgage renewal shock is largely a fixed-rate phenomenon. If you have held a variable-rate mortgage since 2021, you took this increase in instalments as prime moved. There is no cliff at maturity because no fixed rate was insulating you.

Prime sits at 4.45% at most lenders, and the best five-year variable rates run 3.35% to 3.49%, roughly prime minus 0.96% to 1.10%. On the same $502,516 balance over 20 years, that is $2,869.88 to $2,905.33 a month — $142 to $177 below the best insured five-year fixed, and well under the 4.49% on most renewal letters.

That is the asymmetry. The 2021 fixed borrower absorbs two to three percentage points in one month; the variable borrower absorbed it over three years and now renews into the cheapest rate on the sheet. The exposure continues: each 25 basis point move in prime shifts the payment by about $12.69 per $100,000 of balance on a 20-year amortization, roughly $64 a month.

The 2026 wrinkle: the next move may be up, not down

The standard answer to mortgage renewal shock for a decade was to take a short term and wait for cuts. That plan does not survive the current curve. The next Bank of Canada decision is Wednesday, October 28, 2026 at 9:45 a.m. ET, published with a Monetary Policy Report, followed by December 9. As of September 30, market-implied odds put a 25 basis point hike at 54% for October 28, with a hike fully priced for December 9. Those odds moved fast — other outlets published a range of roughly 38% to 60% for October that same week — so treat them as a moving expectation, not a schedule. The implied path reaches prime 4.70% by end-2026 and 5.70% during 2027.

The reason is uncomfortable. August CPI ran 3.0% headline with core at 2.0%, driven mainly by gasoline up 23% year over year, while the labour market shed 42,000 jobs, unemployment held at 6.4% and wage growth fell to 2.0% — a central bank pushed toward tightening into a slowing economy. Bank economists are less hawkish: RBC and Scotiabank see 2.50% by end-2026, while BMO, TD, CIBC, National Bank, Desjardins, Capital Economics and Oxford Economics expect a hold at 2.25%. None forecast cuts that would rescue a 2026 renewal. These are expectations that can change, so budget for the payment you can get today.

What actually lowers your renewal payment

Only a few levers exist, and all beat hoping. Using the $600,000 scenario:

Lever	New monthly payment	vs $3,046.84 baseline
Renew at 4.04% into the remaining 20-year amortization	$3,046.84	baseline
Re-extend the amortization to 25 years at 4.04%	$2,654.24	−$392.60/mo
Pay a $25,000 lump sum before renewal, keep 20 years	$2,895.26	−$151.58/mo
Sign a 4.49% offer instead of shopping down to 4.04%	$3,165.23	+$118.38/mo

• Extending the amortization is the biggest single lever. Going back to 25 years instead of the remaining 20 cuts $392.60 a month off this file. The trade is real — five more years of debt and more interest overall — but it can be the difference between a payment that works and one that does not. Availability depends on your lender and on whether the mortgage is insured, so ask first.
• A lump sum is worth about $6 a month per $1,000. Here, $25,000 applied before maturity takes $151.58 off the payment — and maturity is the one moment you can pay down any amount with no prepayment charge.
• Shopping the rate is worth roughly a lump sum. The gap between 4.04% and 4.49% is $118.38 a month here — $1,421 a year, about $7,100 over the term. That is the price of signing the first offer in the mail.
• Check shorter terms. Three-year fixed near 4.29% prices at $3,112.33 here, and shorter terms have held up better than five-year on some sheets.
• Start four months out and secure a rate hold. With hike odds where they are, a hold has option value — timelines are in How Early Can You Renew Your Mortgage in Canada?

Switching lenders may mean requalifying. Staying does not.

This detail quietly keeps borrowers in expensive renewals. Stay with your current lender and sign what they offer and you are generally not underwritten again — no new stress test, no fresh income review. Move to a new lender and it underwrites from scratch, which may mean requalifying at the stress-test rate on your current income and debts.

For a household whose income has slipped or whose debt load has grown since 2021, that is not theoretical. When it applies is covered in The Mortgage Stress Test in 2026: When It Applies and When It Doesn't. It still does not justify signing without looking: find out what the market will give you first, and if you cannot qualify elsewhere, your lender's offer is still there and you have a reason to negotiate it.

Common questions

How much will my mortgage payment go up at renewal in 2026?

It depends on your original rate, balance and remaining amortization, but the pattern is consistent. A $600,000 mortgage taken in 2021 at 1.99% on a 25-year amortization paid $2,537.81 a month and has a balance near $502,516 after five years. Renewing into the remaining 20 years costs $3,046.84 at 4.04% or $3,165.23 at 4.49% — up $509.03 or $627.41 a month, or $6,108 to $7,529 a year. The proportional increase is the same at $400,000 and $800,000: about 20.1% and 24.7%. Run it on your own balance, because the remaining amortization matters as much as the rate.

Can I extend my amortization at renewal to lower the payment?

Often, yes, and it is the most powerful lever available. On the $502,516 balance above, resetting to a 25-year amortization instead of the remaining 20 drops the payment from $3,046.84 to $2,654.24 — $392.60 a month. The cost is five more years of interest, so it is a cash-flow decision, not a saving. Availability depends on the lender and on whether your mortgage is insured, and it sometimes requires a refinance rather than a straight renewal.

Should I renew early to avoid a rate hike?

Securing a rate hold is cheap insurance right now. Market-implied odds have a 25 basis point hike at 54% for October 28 and fully priced for December 9, and a hold protects you if that happens while still letting you take a lower rate if one appears before closing. Do not treat those odds as certainty — they ranged from roughly 38% to 60% inside one week in late September. Hold a rate because it costs nothing, not because anyone can tell you where rates are going.

What to do before your maturity date

Mortgage renewal shock is manageable four months out and unmanageable three weeks before maturity. Renewing a mortgage in Canada well is mostly preparation: work out your real balance and remaining amortization, price the payment at 4.04% and at 4.49%, decide whether extending the amortization or a lump sum is your lever, and secure a rate hold while the October and December decisions are still ahead.

Then compare the whole market instead of one lender's renewal letter. RateShop.ca is Canada's independent mortgage shopping and comparison marketplace — put A lender, B lender and private options side by side and see what your file is actually worth before signing. On a $502,516 balance, the spread between the best insured rate and the standard quote is about $7,100 over the term — reason enough to spend an afternoon on it.
