What "fixed" and "variable" actually mean in Canada
In Canada, a fixed-rate mortgage locks your interest rate for the entire length of your term — typically 1, 2, 3, 4, 5, 7, or 10 years. Your payment never changes during that term. At maturity, you renew at whatever rates are available then.
A variable-rate mortgage moves with your lender's prime rate, which moves with the Bank of Canada's policy rate. You're typically quoted as "prime minus 0.95%" or "prime plus 0.50%" — a fixed discount or premium to prime that doesn't change, even though prime itself does.
Two kinds of variable
Variable mortgages come in two flavours:
- Variable-rate variable-payment (VRVP): your payment changes when prime changes. More common in 2026.
- Variable-rate fixed-payment (VRFP): your payment stays the same, but the split between principal and interest shifts. If rates rise enough, you can hit a trigger rate where the entire payment goes to interest — and the lender forces a payment increase or term extension.
If your lender offered you a variable in 2020-2022 with fixed payments, you may have hit your trigger rate during the 2022-2023 rate-hike cycle. Check your statement carefully — the amortization may have extended without you realizing.
The 2026 rate environment
Through 2025 the Bank of Canada cut its policy rate several times as inflation moderated. The market is pricing in further easing in 2026, though the pace depends on inflation data, US Federal Reserve moves, and Canadian dollar strength.
What that means for variable
Variable rates today are roughly 50 basis points below 5-year fixed. If the BoC delivers the cuts the market expects through 2026, that gap widens — variable holders pay less.
What that means for fixed
5-year fixed rates have been gradually drifting down with bond yields. Locking a fixed today means you're betting that future rates won't fall meaningfully below today's posted rate over the next 60 months.
When fixed is the right call
Choose fixed when:
Payment certainty matters more than potential savings
First-time buyers near the affordability edge, retirees on fixed income, anyone whose budget has no slack for a payment jump. The peace of mind from knowing exactly what you owe each month for the next 5 years is worth real money.
You're close to the affordability ceiling
If you needed to use a 30-year amortization or stretch your GDS/TDS ratio to qualify, you don't have room for a variable-rate surprise. Fixed protects you.
You'd lose sleep over rate moves
Behavioural reality matters. If checking the Bank of Canada calendar every six weeks would stress you out, fixed lets you set it and forget it.
When variable is the right call
Choose variable when:
Your budget can absorb a 100-200 bps shock
Run the math: if your variable rate is 4.30% today and worst-case rises to 6.30%, can you still make that payment without selling? If yes, you're a variable candidate.
You believe rates will keep falling
Variable benefits when rates drop, because both your rate and your monthly interest move down. Fixed locks you into today's rate even if rates fall 200 bps next year.
You might break the mortgage early
Variable-rate mortgages typically have lower break penalties (3 months interest) than fixed (interest rate differential, which can be much higher). If there's any chance you'll sell, refinance, or break early, variable's flexibility is valuable.
A worked example — $720,000 over 5 years
Imagine a $720,000 mortgage with 25-year amortization. Let's price both options at January 2026 rates:
- 5-year fixed at 4.84%: monthly payment $4,124. Total paid over 5 years: $247,440. Remaining balance at year 5: ~$609,000.
- 5-year variable at 4.30%, assuming no further moves: monthly payment $3,915. Total paid over 5 years: $234,900. Remaining balance: ~$601,000.
Static variable saves $12,540 in payments over 5 years AND pays down $8,000 more principal — a $20,000+ swing.
But what if rates rise?
If variable rises to 5.30% by year 2 and stays there: total paid over 5 years ~$248,000. Roughly break-even with fixed.
And if rates fall?
If variable falls to 3.80% by year 2: total paid over 5 years ~$228,000. Variable wins by ~$20,000.
The right way to think about variable is as a bet on the next 5 years of monetary policy. Fixed pays a 50 bps premium today to take that bet off the table.
The hybrid option — convertible variable
Most Canadian lenders let you convert a variable mortgage to fixed any time during the term, at the lender's then-posted fixed rates. This is the "best of both worlds" framing — but the catch is you'll only convert at rates likely higher than what you could have locked in today.
Conversion makes sense when you've been in variable for a year or two, rates have stabilized, and you want to lock in for the rest of your term.
Decision framework
Use this short checklist:
- **Run affordability at fixed AND at variable + 200 bps.** If you qualify at both, variable is on the table. If only at fixed, fixed wins.
- **Calculate the 5-year payment difference using the mortgage payment calculator.** Quantify what you'd save in the base case.
- Stress test the variable. What's your monthly outflow if prime rises 200 bps? Can you handle it without selling?
- Consider your timeline. Selling or refinancing in < 5 years? Variable's lower break penalty matters.
- Be honest about your temperament. Lose-sleep risk is real and worth pricing.
Common questions
Are variable rates always cheaper?
Not always. In rising-rate environments (2022-2023 in Canada), variable rates climbed above fixed within months. Today's variable advantage is conditional on BoC easing.
Can I switch from variable to fixed without penalty?
Yes — most lenders allow free conversion to fixed at any point during the term, but at the lender's posted fixed rate at the time of conversion.
What's a "trigger rate" and should I worry?
If you have a variable-rate fixed-payment mortgage and rates rise enough that your fixed payment no longer covers the interest, you hit the trigger rate. Your lender will require you to either increase payments, make a lump-sum payment, or extend the amortization. Check your contract for your specific trigger mechanics.
Are HELOCs the same as variable mortgages?
No. HELOCs are revolving credit lines secured by your home, priced at prime + a spread. They're typically variable-rate, but they're not amortizing — minimum payments are interest-only.
Bottom line
In 2026, variable is the math-favoured choice for borrowers who can stomach the volatility. Fixed is the right call for everyone else — and "everyone else" includes most first-time buyers and anyone close to their affordability ceiling.
