Fixed vs Variable Mortgage in Canada 2026: Real Math
If you’ve spent any time on Canadian personal finance forums lately, you’ve seen this debate play out hundreds of times. Fixed or variable? The honest answer is: it depends on your situation, your risk tolerance, and some actual math â not vibes.
We’re going to run real numbers using current 2026 rate environments, look at what each option actually costs you over time, and give you a straight answer on which one makes more sense depending on your circumstances.
Where Rates Actually Sit Right Now
As of early 2026, after the Bank of Canada’s rate-cutting cycle that started in 2024, here’s roughly where the market stands:
| Mortgage Type | Typical Rate Range (2026) | What Moves It |
|---|---|---|
| 5-Year Fixed | 4.29% â 4.89% | Bond yields (5-year GoC bonds) |
| 3-Year Fixed | 4.09% â 4.59% | Bond yields (3-year GoC bonds) |
| Variable Rate | 4.00% â 4.45% | Bank of Canada overnight rate |
| 1-Year Fixed | 4.49% â 5.10% | Short-term bond market expectations |
Notice something? The spread between fixed and variable is much narrower than it was in 2020â2021, when variable rates were sitting near 1% and five-year fixed rates were around 2%. That historical gap is precisely why variable mortgages won so decisively for borrowers in that era. Today’s environment is more nuanced.
The Basic Definitions (Quickly)
Fixed rate: Your interest rate is locked for the term (usually 1, 2, 3, or 5 years). Your payment doesn’t change. The bank takes on the interest rate risk; you pay a premium for that certainty.
Variable rate: Your rate floats with the Bank of Canada’s overnight rate, usually expressed as prime minus or plus a percentage. You take on the interest rate risk. In exchange, you historically pay less â though not always.
Real Math: $500,000 Mortgage Over 5 Years
Let’s use a $500,000 mortgage with a 25-year amortization and compare a 5-year fixed at 4.59% against a variable rate starting at 4.20%, assuming two different rate scenarios.
Scenario A: Rates Drop 50 Basis Points Over the Term
| Metric | 5-Year Fixed (4.59%) | Variable (starts 4.20%, ends ~3.70%) |
|---|---|---|
| Starting Monthly Payment | $2,771 | $2,714 |
| Total Interest Paid (5 Years) | ~$108,900 | ~$99,600 |
| Principal Paid Down | ~$57,700 | ~$59,100 |
| Penalty to Break (3-year mark) | ~$9,000â$15,000 IRD | ~$3,600 (3 months interest) |
| Winner | â | Variable saves ~$9,300 |
Scenario B: Rates Rise 75 Basis Points Over the Term
| Metric | 5-Year Fixed (4.59%) | Variable (starts 4.20%, ends ~4.95%) |
|---|---|---|
| Starting Monthly Payment | $2,771 | $2,714 |
| Total Interest Paid (5 Years) | ~$108,900 | ~$116,200 |
| Principal Paid Down | ~$57,700 | ~$55,900 |
| Penalty to Break (3-year mark) | ~$9,000â$15,000 IRD | ~$4,200 (3 months interest) |
| Winner | Fixed saves ~$7,300 | â |
The math isn’t dramatic either way when the spread is this narrow. That’s the key insight for 2026: you’re not making a $30,000 decision like borrowers in 2022 were. You’re making a $7,000â$10,000 decision, which is still meaningful, but the stakes are lower than they used to be.
The Break-Even Calculation
Here’s a quick way to think about whether variable makes sense: how much does the Bank of Canada rate need to move â and in which direction â for your variable mortgage to outperform?
If your 5-year fixed is 4.59% and your variable starts at 4.20%, you’re already 39 basis points ahead on the variable. For the fixed to win, rates would need to rise enough above 4.59% for long enough to eat through that initial advantage.
Rough rule of thumb: if you believe the Bank of Canada’s overnight rate will average higher than your fixed rate over the full term, go fixed. If you believe it will average lower, go variable. The problem, of course, is that nobody reliably knows.
What the Research Actually Shows
A frequently cited study from mortgage researcher Moshe Milevsky found that, historically, variable rate mortgages outperformed fixed rates about 77% of the time in Canada over multi-decade periods. That’s a real number worth knowing.
But here’s what that stat doesn’t capture: the 23% of the time fixed won often coincided with periods of serious financial stress â exactly when having a higher payment would hurt the most. Historical averages don’t tell you how you’ll feel when your variable payment jumps $400 in a year, as happened to many Canadians between 2022 and 2023.
Side-by-Side Feature Comparison
| Feature | Fixed Rate | Variable Rate |
|---|---|---|
| Payment predictability | â Locked in for the term | â Changes with prime rate |
| Break penalty | â IRD â can be very expensive | â Usually 3 months interest |
| Rate in falling environment | â You’re stuck at your locked rate | â Payment drops automatically |
| Rate in rising environment | â Protected | â Payment increases |
| Ability to convert | Limited options mid-term | â Can usually lock in anytime |
| Stress test qualification | Higher qualifying rate required | Same stress test applies |
| Budgeting simplicity | â Simple | Requires cash flow buffer |
| Historical performance | Wins ~23% of the time | Wins ~77% of the time |
The Penalty Problem Nobody Talks About Enough
One of the most underappreciated parts of this decision is the break penalty. Life changes. People sell houses, refinance, or need to restructure. About one in three Canadian mortgages gets broken before the end of the term.
Variable rate penalties are almost always three months of interest. On a $500,000 mortgage at 4.20%, that’s roughly $5,250. Painful, but manageable.
Fixed rate penalties at the big banks use an Interest Rate Differential (IRD) calculation that can be genuinely brutal. Some borrowers have faced penalties of $20,000â$30,000 when breaking a fixed mortgage taken at a higher rate in a now-lower rate environment. Monoline lenders and credit unions often use simpler penalty formulas, which is one reason shopping beyond the Big Six banks makes sense.
If there’s any meaningful chance you’ll need to break your mortgage early â job change, growing family, relationship change â the variable rate’s simple penalty structure has real financial value that doesn’t show up in pure rate comparisons.
When to Pick Fixed
- You’re at the edge of your budget. If a $300â$400 monthly payment increase would genuinely strain your finances, the certainty of fixed is worth the premium.
- You sleep better with predictability. This is a legitimate factor. A mortgage you can actually live with comfortably beats a theoretically optimal one that keeps you anxious.
- You’re fairly certain you’ll hold the mortgage for the full term. If you’re not moving, not refinancing, and not expecting major life changes, the IRD penalty risk is lower.
- You believe rates will rise significantly. If your read on the Bank of Canada is that more hikes are coming, locking in makes mathematical sense.
- You’re a first-time buyer stretching your budget. Rookie mistake: taking variable to save $150/month when that savings disappears the first time rates tick up.
When to Pick Variable
- You have a financial cushion. If you can absorb a payment increase of $400â$600/month without real hardship, you can ride out rate volatility and capture the historical variable advantage.
- You expect rates to fall or stay flat. The Bank of Canada’s cutting cycle has room to continue if the economy softens â variable holders benefit automatically.
- You might sell or refinance within the term. The simpler break penalty alone can justify variable for households with any meaningful likelihood of early termination.
- You want flexibility to lock in later. Most variable mortgages let you convert to fixed during the term if your outlook changes.
- The spread is meaningful. If variable rates were 150+ basis points below fixed, the math heavily favors variable. At 39 basis points, it’s more of a judgment call â but still leans variable for flexible households.
A Practical Middle Path: Shorter Fixed Terms
One option many borrowers overlook: a 2- or 3-year fixed rate. In 2026, you can often get a 3-year fixed around 4.09â4.39%, which gives you meaningful rate certainty without locking in for the full five years. If rates do fall further, you’re not trapped as long. If rates rise, you’re protected for three years.
For borrowers who want predictability but are nervous about committing to a 5-year term in an uncertain rate environment, shorter fixed terms are worth running through your own numbers.
The Bottom Line
In 2026, with the spread between fixed and variable rates narrower than it’s been in years, this isn’t the enormous financial decision it was in 2022. But it’s still worth getting right.
Variable has the historical track record and the flexibility advantage. Fixed has the predictability and the protection against the scenario nobody wants. The best mortgage is the one that fits your actual cash flow, your realistic life plans, and your genuine (not aspirational) risk tolerance.
Run the numbers for your specific mortgage amount. Talk to a fee-for-service mortgage broker who isn’t incentivized to push one product. And remember: the difference between a decent mortgage decision and a great one is usually much smaller than the difference between any mortgage and no mortgage at all.
