Choosing between a variable rate mortgage and a fixed rate mortgage in Canada in 2026 comes down to four questions: how much rate risk you can absorb, how long you plan to keep the mortgage, what the spread is between the two on the day you sign, and whether you prefer a static payment that does not change with the prime rate. Historically, variable rate mortgages have produced lower lifetime interest cost in Canada most of the time, but the 2022-2024 rate shock showed that “most of the time” can mask multi-year periods of meaningful pain.
The two products at a glance
| Feature | Fixed rate | Variable rate |
|---|---|---|
| Rate set at | Closing, fixed for term (typically 5 years) | Lender prime + or – a discount, adjusts when prime changes |
| Monthly payment | Constant for the term | Two flavours: adjustable-rate (payment moves with prime) or variable-rate (payment static, but more goes to interest when prime rises) |
| Prepayment penalty if breaking early | Greater of 3 months interest or interest rate differential (IRD); IRD often large | 3 months interest only |
| Convertibility | n/a | Most variable mortgages can be converted to a fixed rate at any time without penalty |
| Trigger rate / point | n/a | If interest exceeds payment, the lender may require a higher payment or extend amortization |
The 2026 decision factors
| Factor | Pulls toward fixed | Pulls toward variable |
|---|---|---|
| Bank of Canada rate outlook | Expect rates to rise | Expect rates to fall or stay flat |
| Spread between products | Variable not noticeably cheaper than fixed | Variable rate at least 0.50 percentage points below fixed |
| Cash flow tolerance | Tight budget; payment shock is risky | Income buffer; can absorb 1-2% rate increase |
| Time horizon for the mortgage | Plan to keep mortgage for full term | Plan to break, refinance, or sell mid-term (variable break penalty is much smaller) |
| Need for predictable budgeting | Yes | Comfortable with monthly variability |
Adjustable-rate vs variable-rate mortgages
Both have a rate that floats with the lender’s prime rate, but the payment behaviour differs:
- Adjustable-rate (true variable payment): Each rate change is reflected in the next payment. Cash flow rises and falls. Less risk of trigger rate problems because principal repayment continues normally.
- Variable-rate (static payment): Payment stays the same in dollars when prime moves. The split between interest and principal shifts. If interest exceeds payment, you hit the trigger rate, and the lender can require a higher payment or push the amortization beyond the original schedule (which can lead to negative amortization at some lenders).
TD, BMO, and CIBC are commonly variable-rate (static-payment) lenders. RBC, Scotia, National Bank, and most credit unions are adjustable-rate. Knowing which one your lender offers matters more than knowing the headline rate.
Worked example: $700,000 mortgage at signing
Two scenarios at March 2026 rates (illustrative):
| Product | Rate | Monthly payment (25 yr) | Year-1 interest |
|---|---|---|---|
| 5-year fixed at 4.59% | 4.59% | $3,901 | $31,628 |
| 5-year variable at 4.95% (prime 6.45% minus 1.50%) | 4.95% | $4,053 | $34,109 |
If prime drops by 50 basis points during 2026, the variable rate falls to 4.45 percent and the year-2 interest cost falls below the fixed-rate scenario. If prime rises by 50 basis points, the variable rate climbs to 5.45 percent and pulls further ahead in cost. Direction of prime over the term of the mortgage drives the lifetime outcome.
Break penalty trap with fixed rates
The interest rate differential calculation used by the big banks for closed fixed mortgages is often surprisingly large. A homeowner with a 5-year fixed at 4.59% who tries to break the mortgage in year 2 to refinance at 3.50% may face an IRD penalty of $20,000 to $40,000 on a $700,000 mortgage. Variable rate mortgages have a much simpler 3-month-interest penalty. If your plans (move, refinance, sell) might force an early payout, the variable mortgage’s smaller penalty often outweighs other considerations.
Conversion option
Most variable rate mortgages can be converted to a fixed rate of equal or greater term at any time without penalty. A common strategy:
- Sign variable today.
- Watch the spread and the Bank of Canada’s projected path.
- If the spread narrows or rates start rising sharply, convert to fixed.
- Keep the option open as long as the variable still saves money each month.
The catch: conversion locks you in at the current fixed rate, which may be higher than what was available at original signing.
What 2022-2024 taught Canadian homeowners
- Variable rate mortgages with static payments hit trigger rates when the Bank of Canada raised rates from 0.25% to 5.00% in 18 months.
- Some borrowers saw their amortizations stretch from 25 years to 35 or even 70 years on paper, with no principal being paid down.
- Lenders eventually required payment increases or lump-sum top-ups to bring amortization back within the original schedule.
- Adjustable-rate (true variable payment) borrowers avoided this trap, but absorbed full payment shock month by month.
- Fixed-rate borrowers escaped the cycle until renewal, when they faced the new rate environment all at once.

Frequently asked questions
- Is a variable rate mortgage better than fixed in Canada in 2026?
- It depends on the spread between products, your rate outlook, and your cash flow tolerance. Historically variable mortgages have produced lower lifetime interest most of the time, but with multi-year periods of pain when rates rise sharply.
- What is the difference between adjustable-rate and variable-rate mortgages?
- Both float with prime, but adjustable-rate mortgages adjust the payment with each rate change, while variable-rate mortgages hold the payment static and shift the interest-principal split. Static-payment variables can hit a trigger rate when interest exceeds the payment.
- Can I convert a variable mortgage to fixed?
- Yes, most variable mortgages allow conversion to a fixed rate of equal or greater term at any time without penalty. The conversion locks you in at the current fixed rate.
- What is a trigger rate?
- The interest rate at which the monthly interest equals the static payment on a variable-rate mortgage. Above the trigger rate, the lender may require a higher payment or extend the amortization.
- Why is the fixed mortgage break penalty often huge?
- Big banks calculate the interest rate differential (IRD) penalty using their posted rates rather than discounted contract rates. The IRD can run $20,000 to $40,000 on a $700,000 mortgage broken mid-term.
- Can I get out of a variable mortgage easily?
- Easier than fixed. The break penalty on a variable rate mortgage is typically three months of interest, not the IRD.
- Should I always pick variable to save money?
- No. Variable saves on average over long periods but at the cost of cash flow uncertainty. If a 1-2 percentage point rate increase would put your monthly budget at risk, fixed protects you better.
