Fixed vs Variable Mortgage in Canada: How to Choose in 2026

"Should I go fixed or variable?" is the question every Canadian mortgage borrower grapples with. The answer changes with the interest rate environment, your risk tolerance, and your specific situation. This guide lays out the honest comparison — historical data, current environment analysis, and the scenarios where each makes sense.

How Fixed and Variable Rate Mortgages Work in Canada

Fixed Rate

Your interest rate is locked for the term (typically 1–5 years in Canada). Monthly payment stays the same throughout the term. If rates fall, you don't benefit — if they rise, you're protected.

✓ Payment certainty
✓ Protection against rate increases
✗ Higher break penalty (IRD)
✗ Miss out if rates fall

Variable Rate

Your rate floats with the Bank of Canada prime rate (expressed as prime ± spread). Rate and payment change as prime changes. Lower than fixed rates historically, but not guaranteed.

✓ Historically lower rates
✓ Lower break penalty (3 months interest)
✓ Benefits if rates fall
✗ Payment uncertainty

Canadian Mortgage Terms: An Important Distinction

In Canada, the term and amortization are different things — a distinction that doesn't exist in the same way in the US:

Amortization: The total length of your mortgage (typically 25 years). This determines your payment size.
Term: The period you're locked into your current rate (1–5 years, sometimes 10). At the end of the term, you renew at whatever rates exist then.

This means a "5-year fixed" mortgage doesn't pay off in 5 years — it renews at year 5, 10, 15, and 20 until the 25-year amortization is complete. The choice between fixed and variable is really a bet on where rates will be at each renewal — not just over the next 5 years.

The Historical Record: Fixed vs Variable in Canada

Historical Finding (1975–2023)

Multiple studies of Canadian mortgage data (including CIBC research) show that variable rate mortgages outperformed 5-year fixed rates approximately 65–70% of the time over rolling 5-year periods. The average variable rate borrower paid $20,000–$30,000 less in interest over a 25-year amortization than the average fixed rate borrower.

The notable exception: 2022–2023. Borrowers in variable rates from 2020–2022 saw rates jump from ~1.45% to ~6.2% as the Bank of Canada raised rates 10 times in 18 months — one of the fastest rate cycles in Canadian history.

Break-Even Analysis: When Fixed Wins

Fixed rates are typically higher than variable rates at the time of signing (this is the "term premium" you pay for certainty). Fixed is the better choice when:

Variable rates rise above the fixed rate you locked in
The rate increase happens early in your term (so you pay the higher variable rate for longer)
The difference between fixed and variable at signing is small (e.g., only 0.25–0.5%)

Scenario (5yr term, $400K)	Fixed at 5.5%	Variable (starts 4.9%)	Winner
Rates unchanged	$105,600	$97,200	Variable saves ~$8,400
Rates drop 1% at year 2	$105,600	$88,400	Variable saves ~$17,200
Rates rise 1% at year 2	$105,600	$107,800	Fixed saves ~$2,200
Rates rise 2% at year 2	$105,600	$118,000	Fixed saves ~$12,400

The Break Penalty Asymmetry

One of the most important but underappreciated differences between fixed and variable is what happens if you need to break your mortgage before the term ends (to sell, refinance, or access equity):

Fixed Rate Break Penalty

The Interest Rate Differential (IRD) — the difference between your rate and the current rate for the remaining term. This can be $20,000–$40,000+ if you break mid-term when rates have fallen significantly.

Variable Rate Break Penalty

Simply 3 months of interest. On a $400K mortgage at 5%, that's about $5,000 regardless of when you break or where rates are. Predictable and relatively modest.

Who Should Choose Fixed vs Variable?

Consider Fixed If:

• Payment certainty is critical (tight budget)
• You're at or near your maximum qualification limit
• Rates are expected to rise (economic consensus)
• You plan to hold the property through the full term
• You have poor risk tolerance or high stress
• The fixed/variable spread is < 0.5%

Consider Variable If:

• You have budget buffer (can absorb rate increases)
• The variable rate is materially lower (0.75%+)
• Rates are expected to fall or stay flat
• You might need to break the mortgage early
• You're comfortable with payment fluctuations
• You have other financial flexibility

The 2026 Environment

As of 2026, the Bank of Canada has been in an easing cycle after the aggressive rate hikes of 2022–2023. Variable rates have declined materially from their peaks. The fixed-variable spread has narrowed. In a declining rate environment, variable rates tend to outperform over the near term.

However, the rate path after 2026 is uncertain. Inflation, US trade policy, and global economic conditions all influence where Canadian rates go. The honest answer is: nobody knows, and your choice should be based on what you can afford if you're wrong.

Frequently Asked Questions

Can I convert from variable to fixed partway through my term?

Yes. Most Canadian lenders allow variable rate mortgage holders to convert to a fixed rate at any time during the term, typically at the current fixed rate for the remaining term length. There is usually no penalty to convert (unlike breaking a fixed mortgage). This is an important feature of variable mortgages — you can lock in if rates start rising sharply.

What is a "static payment" vs "adjustable payment" variable mortgage?

Some Canadian variable mortgages keep your payment amount fixed while adjusting how much goes to principal vs interest (static/fixed-payment variable). Others adjust your actual payment with the prime rate (adjustable-payment variable). The adjustable version makes rate changes immediately visible in your monthly budget.
