Variable or Fixed in Late 2026: How to Choose With a Rate Hike on the Table

Rate decision watch, September 19, 2026. The variable or fixed mortgage question has flipped direction. For four years the only argument was how fast the Bank of Canada would cut. Now the market is pricing a 54% chance of a 25 basis point hike on October 28 and, as of September 30, effectively certain odds of one on December 9. Variable still starts cheaper: roughly 3.35% to 3.49% against 4.04% on the sharpest insured five-year fixed and 4.39% to 4.49% more broadly. The real question is how many hikes it takes to erase that head start.

Below is that arithmetic on a $500,000 mortgage over 25 years, plus why an adjustable rate mortgage and a static-payment variable behave nothing alike, where a short fixed term fits, and what convert-to-fixed is worth.

The spread you are choosing between

The prime rate sits at 4.45%, about 220 basis points above the 2.25% policy rate held for seven straight decisions. Discounts of prime minus 0.96% to prime minus 1.10% produce today's variable quotes. Fixed pricing comes from the bond market, where the five-year Government of Canada yield near 3.6% has pushed fixed rates up roughly half a point — mechanics covered in our rate alert on rising fixed mortgage rates.

Term	Approximate rate	Payment on $500,000, 25-year amortization
5-year variable rate (best)	3.35%	$2,457
5-year fixed rate, insured (best)	4.04%	$2,641
5-year fixed, broadly quoted	4.49%	$2,765
3-year fixed	4.29%	$2,709
2-year fixed, insured	5.09%	$2,934

Payments use the Canadian semi-annual compounding convention. Rates vary by lender, province, loan-to-value and credit profile, so read these as the market's shape, not your quote.

The breakeven: how many hikes erase variable's head start

At 3.35% against a 4.04% fixed, variable starts $184 a month cheaper and builds equity faster, because more of each payment lands on principal. Both advantages shrink with every hike. Here is the cumulative picture over 24 months, the variable modelled as an adjustable rate mortgage re-amortizing at each change.

Scenario	Rate, month 24	Payment, month 24	Interest, 24 months	Balance, month 24	Versus the fixed
4.04% five-year fixed (benchmark)	4.04%	$2,641	$39,146	$475,764	—
No hikes, variable holds	3.35%	$2,457	$32,432	$473,466	−$6,714 interest, −$2,298 owed
+50 bp by end-2026	3.85%	$2,589	$36,877	$475,009	−$2,269 interest, −$755 owed
+125 bp by mid-2027 (implied path)	4.60%	$2,790	$41,990	$476,697	+$2,843 interest, +$933 owed

Two things stand out. The two-hike case still favours variable: even if both pending decisions deliver, the variable holder is $2,269 of interest ahead at month 24 and owes $755 less. And the break point sits further out than headlines suggest. Adding hikes one at a time, variable is still $359 ahead at three — a rounding error — and only falls $1,345 behind at the fourth. Roughly four 25 basis point hikes inside two years is where fixed starts winning the variable or fixed mortgage trade.

The published forecast for the lowest five-year variable rate, about 3.60% by end-2026 and 4.35% by mid-2027, sits between the second and third scenarios. On that path the two land close to a tie over 24 months: the market has priced the easy answer out of this decision. Our piece on the 54% hike odds for October 28 shows where they come from.

ARM or VRM changes the risk more than the rate does

Two mortgages can both be sold as variable and behave nothing alike. An adjustable rate mortgage passes every prime move straight to your payment. A static-payment variable keeps the payment level and shifts the interest-principal split, so a hike stretches your amortization, not your budget — invisible in a flat market, expensive in a rising one.

Take the +125 basis point scenario. The adjustable holder's payment climbs from $2,457 to $2,790, leaving a $476,697 balance at month 24. The static-payment holder keeps paying $2,457 but owes $483,248 — $6,551 more — with implied remaining amortization stretched from 23 years to roughly 30. Push far enough and the payment stops covering interest: that is the trigger rate, enforced with a lump sum demand or forced increase.

• Ask which structure you are being sold. Lenders market both as variable; the difference appears only in the commitment letter.
• On a static-payment variable, get the trigger rate in writing and know what prime reaches it.
• On an adjustable, stress your budget at prime 5.70%, the 2027 level in the implied path, not today's 4.45%.
• Either way, set your payment above the minimum now — the cheapest hike insurance going, and usually reversible.

Our breakdown of what happens if prime hits 4.70% goes decision by decision.

The short-term fixed middle path, and its catch

The standard advice when nobody can call direction is to shorten the term and renew into whatever 2029 looks like. Sound logic; the pricing is where it gets interesting. Two-year insured fixed is about 5.09%, a full point above the three-year at roughly 4.29%. On $500,000 that is $2,934 a month against $2,709 — $225 more for a shorter commitment. The two-year is the worst value on most lender sheets; the three-year deserves a look.

The three-year is not free either. Against the 4.04% five-year it costs $68 more a month and about $2,434 more interest over 24 months. That is the price of optionality. If this cycle is a tariff-and-oil episode that unwinds, a fair premium. If 3.0% headline inflation and a neutral range of 2.25% to 3.25% say the floor moved up permanently, lock longer.

Variable or fixed mortgage: who should take which

The fixed vs variable rate Canada debate has no universal answer. Which mortgage rate should I choose comes down to the payment volatility your budget survives.

Lean variable if

You have genuine payment room — prime at 5.70% is an annoyance, not a problem. Or you might sell, refinance or break inside three years, since variable penalties are typically three months' interest, not an interest rate differential running into five figures. Or you are renewing off a 2020–2021 variable and have absorbed most of this cycle, unlike the holders in our piece on renewal shock for 1.15 million Canadians.

Lean fixed if

Your budget is tight, your income is uneven, a $300 to $400 swing would force a hard decision, or you do not want to revisit this until 2031. At 4.04% insured you pay about $184 a month for that: a defensible price for certainty.

Lean three-year fixed if

You want the hikes off the table without committing through 2031, and can absorb $68 a month against the five-year. The quiet favourite for borrowers who find the next two years unreadable.

The convert-to-fixed option, and what it is worth

Most lenders let you convert a variable mortgage to fixed mid-term with no penalty. A real option, and narrower than it sounds. You convert at the rate available that day, usually the lender's in-market or posted fixed rather than the sharpest discount on the street — and the moment you most want to convert is the moment fixed rates have already repriced. Say two hikes land, your variable is at 3.85%, and you convert after six months with a $493,820 balance. If fixed pricing has risen half a point to 4.54%, your payment goes from $2,589 to $2,775 — worse than the 4.04% available on day one.

Treat conversion as a brake, not a strategy. Confirm it exists, whether it converts into discounted or posted rates, and the minimum remaining term.

Nobody can call this, and the forecasts prove it

The state of play is a genuine split. RBC and Scotiabank see 2.50% by end-2026. National Bank, CIBC, Desjardins, Capital Economics, BMO and Oxford Economics have the Bank holding at 2.25% through 2026; TD has it flat for years. The market curve is more hawkish than almost every bank economist. One side will be wrong, and nobody can tell you which.

The data before October 28 decides it: the labour report on October 9, September CPI on October 19, and August GDP on October 30. August brought a 42,000-job loss and wage growth down to 2.0%, the slowest in four years — not an economy needing tighter policy. Gasoline at plus 23% is. Every forward-looking figure here is a market expectation that can change.

Common questions

Is variable or fixed better right now in Canada?

On the arithmetic, variable stays ahead through roughly four 25 basis point hikes over two years, and the market is pricing one to two by end-2026. That makes variable the mathematically favoured side of the variable or fixed mortgage choice today — but only if your budget absorbs the scenario where it is wrong. If a $333 monthly increase would hurt, take the 4.04% insured fixed.

Can I switch from variable to fixed mid-term?

Usually yes. Most Canadian lenders include a conversion clause letting you move to a fixed term with no prepayment penalty, typically into a term at least as long as the one remaining. The limitation is pricing: you take the rate on offer that day, often not the best discounted rate, and by then fixed rates have moved. Confirm the clause before signing.

How much does a 0.25% rate hike cost per month?

On an adjustable rate mortgage with a 25-year amortization, about $13 per $100,000 borrowed. That is $66 a month on $500,000, roughly $791 a year, and about $266 a month if four hikes land. On a static-payment variable the monthly cost is zero: the hike arrives as a longer amortization and a higher balance — the same money paid later.

What to do before October 28

If you are closing or renewing within 120 days, get a rate hold now — it costs nothing and covers both pending decisions. If you already hold a variable, pull the commitment letter and establish whether your payment or your amortization moves, and what your trigger rate is.

Then shop the decision, not just the rate. The gap between the sharpest insured five-year fixed at 4.04% and the broadly quoted 4.39% to 4.49% is about $124 a month on $500,000, dwarfing most of the variable or fixed mortgage gap debated here. Appetite for variable discounts, conversion terms and penalties varies more than headline numbers do, and the lender sharp on fixed is often not sharp on variable.
