Fixed vs Variable Mortgage in Edmonton
How to choose between rate stability and floating with the Bank of Canada
A widely cited 2001 study by York University’s Moshe Milevsky found that variable-rate mortgage holders paid less interest than fixed-rate borrowers roughly 90% of the time over any given five-year period (Ratehub, citing Dr. Moshe Milevsky, 2001). That’s a powerful stat, but it doesn’t tell you what to do right now, when the Bank of Canada has just raised its policy rate to 2.50% and said it could need to go higher (Bank of Canada, 2026).
Here’s how to decide between variable and fixed for your Edmonton purchase or renewal — with real numbers, not gut feelings.
Key Takeaways
– At this guide’s example rates, 4.25% variable and 4.75% fixed, the spread is 50 basis points. They show the math and aren’t quotes, because advertised rates can change within 24 hours.
– Historically, variable-rate borrowers have saved money roughly 90% of the time over any 5-year term (York University / Milevsky, 2001).
– The 2025 CMHC Mortgage Consumer Survey found 62% of borrowers chose fixed while 25% chose variable (CMHC, 2025).
– Variable mortgages usually carry a 3-month interest penalty to break early; fixed mortgages use the higher of 3-month interest OR the interest rate differential (IRD), which can be much larger.
– The Greater Edmonton Area’s average home price was $466,080 in September 2026, up 2.9% year over year (REALTORS Association of Edmonton).
How Does a Fixed-Rate Mortgage Work?
A fixed-rate mortgage locks your interest rate for the entire term — typically three or five years in Canada. Your payment stays identical from month one to the final payment of the term, regardless of what the Bank of Canada does with its overnight rate. Fixed rates are priced off Government of Canada bond yields, not the BoC policy rate directly (Ratehub, 2026).
That predictability comes at a cost. Fixed rates are almost always higher than variable rates at the time of signing because the lender is absorbing the risk that rates might rise during your term.
The other hidden cost? Break penalties. If you sell, refinance, or need to break your fixed mortgage early, the penalty is usually the higher of three months’ interest OR the interest rate differential (IRD) (Financial Consumer Agency of Canada). The IRD depends on your rate, your remaining term and current rates, and it can run far above three months’ interest.

How Does a Variable-Rate Mortgage Work?
A variable-rate mortgage is tied to your lender’s prime rate, which moves in lockstep with the Bank of Canada’s overnight rate. Your rate is expressed as “prime minus” or “prime plus” a discount, for example, prime minus 0.60%. With the big banks’ prime rate at 4.70% since October 29 (RBC, 2026), that would give you an effective rate of 4.10%. Our example variable rate of 4.25% works out to prime minus 0.45%.
There are two flavours of variable in Canada:
- Adjustable-rate mortgage (ARM): your payment changes each time prime moves, so you always pay the correct split of principal and interest.
- Static-payment variable: your payment stays the same, but the split between principal and interest shifts. If rates rise enough, you can hit your trigger rate — the point where your entire payment covers only interest and no principal is being repaid.
The fixed-payment variety created problems for some borrowers during the 2022-2023 rate hikes, when they hit trigger rates. It matters again now: after the October increase, more of each fixed payment goes to interest (Canadian Mortgage Trends).

Historical Performance: Which Rate Type Actually Wins?
The data overwhelmingly favours variable — but the margin depends on the period you examine. Dr. Moshe Milevsky’s landmark study at York University’s Schulich School of Business analysed data from 1950 to 2007 and found variable-rate borrowers came out ahead roughly 90% of the time over rolling five-year windows (Ratehub, citing Milevsky, 2001). A later CMLS Financial study covering 25 years of data confirmed the pattern, showing variable won in the majority of periods (CMLS, 2023).
But here’s the caveat: 2022-2024 was the exception. The Bank of Canada hiked its policy rate 10 consecutive times, from 0.25% to 5.00%, in the fastest tightening cycle in Canadian history. During that window, variable-rate borrowers paid substantially more than those locked into pre-2022 fixed rates. It was a painful reminder that historical averages don’t eliminate short-term risk.
The lesson? Variable wins most of the time, but “most of the time” isn’t “all of the time.” Your decision should factor in how much short-term volatility you can absorb financially and psychologically.
The Rate Environment: What the Bank Did and What It Means
The Bank of Canada cut its policy rate from a peak of 5.00% to 2.25% through 2024 and 2025. On October 28, 2026, it raised the rate to 2.50%, its first increase since July 2023 (Bank of Canada, 2026). CPI inflation has been around 3% since April and is expected to reach about 3½% by the end of the year. The next scheduled decision is December 9, 2026. Our recap of the decision has the details.
Here are the example rates this guide uses:
| Product | Example rate | Monthly payment on $450,000 over 25 years |
|---|---|---|
| 5-year fixed | 4.75% | About $2,554 |
| 5-year variable | 4.25% | About $2,428 |
| Spread | 0.50% | About $125 |
Examples only, not quotes. Advertised rates can change within 24 hours. Your actual rate depends on credit, down payment, and property type.
During 2022-2023, the spread inverted and variable was actually higher than fixed, a side effect of the fastest rate-hike cycle in Bank of Canada history. When variable sits below fixed, as it does in our example, it has a head start but not a guarantee.
What happens next is uncertain. The Bank says “there could be a need to increase the policy rate further,” and that it will take future decisions one meeting at a time (Bank of Canada, 2026).
When Does Variable Win?
Variable tends to outperform fixed in three specific scenarios:
1. Rate-Cutting or Stable Rate Environments
When the Bank of Canada is cutting rates or holding steady, your variable rate stays flat or drops while fixed-rate borrowers are locked into the higher rate they signed at. That’s not the backdrop today: the Bank just raised its rate, so a variable borrower needs room in the budget if more increases come.
2. You Might Move or Refinance Before Term Ends
On a variable mortgage, the penalty is usually three months’ interest, about $4,780 on $450,000 at 4.25%. On a fixed mortgage it’s the higher of three months’ interest or the IRD, which can be much larger. If there’s any chance you’ll sell your Edmonton home before the five-year mark, variable gives you an easier exit.
3. You Can Absorb Payment Swings
A 0.25% BoC rate increase on a $450,000 variable mortgage adds roughly $62 per month to your payment. If your budget has that kind of buffer, the statistical advantage of variable, saving money the majority of the time, works in your favour over multiple terms.

When Does Fixed Win?
Fixed earns its premium in three situations:
1. Aggressive Rate-Hike Cycles
The Bank of Canada raised its rate in October and says it could do so again. If it keeps going, a fixed rate shields you entirely. The 2022-2023 cycle proved that even a “historically better” variable rate can cost thousands more per year in a hiking environment.
2. You’re Stretching Your Budget
If you’re buying at or near your maximum qualification and every dollar of payment predictability matters, fixed eliminates the risk of a surprise increase. Payment certainty is financial safety as well as emotional comfort.
3. You Plan to Hold the Full Term
If you’re confident you won’t sell, refinance, or make major changes for the full five years, the IRD penalty disadvantage of fixed rates becomes irrelevant. You’ll never pay it. In that case, the premium for fixed is purely an insurance cost against rate increases, and whether that insurance is worth the higher rate depends on your risk tolerance.
Stress Test Impact: Variable vs Fixed
Both variable and fixed mortgages face the same stress test: you qualify at your contract rate + 2% OR 5.25%, whichever is higher (OSFI, 2024). But because variable rates start lower, they produce a lower qualifying rate:
| 5-year variable | 5-year fixed | |
|---|---|---|
| Example rate | 4.25% | 4.75% |
| Qualifying rate (contract rate + 2%) | 6.25% | 6.75% |
| Payment at the qualifying rate on $450,000, 25 years | about $2,946 | about $3,083 |
The lower qualifying rate means about $136 less in test payments on this example, so the same income can qualify for a somewhat larger variable mortgage. How much depends on your income, debts, property tax and heating costs.
The Break Penalty Factor: Why It Matters More Than the Rate
Plans change, and a mortgage broken early costs money. That makes the break penalty one of the most underrated factors in the variable vs fixed decision.
Three months’ interest on $450,000 is about $4,780 at 4.25% and about $5,340 at 4.75%. A fixed mortgage can cost more than that because the penalty is usually the higher of three months’ interest or the IRD (Financial Consumer Agency of Canada). Your lender calculates the IRD and can give you the figure before you decide.
The variable penalty is easier to predict. The fixed penalty depends on the IRD calculation, which varies by lender and can grow if rates have dropped since you signed.
If there’s a real chance you’ll break your mortgage before term, the penalty difference deserves as much attention as the rate.

Decision Framework: 5 Questions to Answer
Not sure which way to lean? Work through these five questions:
1. How long will you stay in this home?
If less than five years: variable’s lower break penalty gives it a structural advantage. If the full term: fixed’s predictability is worth more.
2. Can you absorb a higher payment?
Each quarter-point increase adds about $62 a month on $450,000, and a full point adds about $253. If yes, variable’s historical advantage can work in your favour. If that would strain your budget: fixed removes the risk entirely.
3. Where do you think rates are headed?
The Bank of Canada says it could need to raise its rate again but will proceed carefully. If you think rates will stay near here, variable can save you money. If you think inflation could force more hikes, fixed is insurance.
4. Is this your first home or a step-up purchase?
First-time buyers tend to move sooner (growing family, job change, upgrade). Variable’s flexibility and lower penalties match that reality. Long-term homeowners who’ve found their “forever” house lean fixed.
5. What keeps you up at night — overpaying or uncertainty?
If the thought of paying more than you need to bothers you most: variable. If the thought of a surprise payment increase keeps you awake: fixed. Neither answer is wrong — it’s about aligning your mortgage with your temperament.
What About a Hybrid Approach?
Some Edmonton buyers split their mortgage — for example, 60% fixed and 40% variable. This hedges your bets: the fixed portion provides stability while the variable portion captures potential savings. According to the CMHC 2025 Mortgage Consumer Survey, 9% of Canadian borrowers chose a combination of fixed and variable (CMHC, 2025).
The trade-off? Two rate products to manage, two potential penalties if you break early, and slightly more complex paperwork. For borrowers who genuinely can’t decide, and who have a mortgage large enough to make the split meaningful, it’s a legitimate middle ground.

Metro’s Recommendation for Edmonton Buyers Right Now
There’s no universal right answer — but there is a right answer for you, and it depends on the five questions above. Here’s how we’d frame it for most Edmonton buyers in today’s market:
- Leaning variable if you have budget flexibility, might move within 5 years, and can live with more rate increases. In our example, the 50 bps head start over fixed is about $125 a month, or roughly $1,500 per year, on a $450,000 mortgage.
- Leaning fixed if you’re buying at your maximum, plan to stay put for the full term, and sleep better knowing your payment won’t change. The premium is the cost of certainty.
- Consider hybrid if your mortgage is large and you truly can’t decide.
Whatever you choose, make sure you’re comparing rates from multiple lenders. As a brokerage with access to 30+ lenders, we can put those offers side by side on your file. Each quarter point on a $450,000 fixed mortgage is about $63 a month.

Frequently Asked Questions
Is variable or fixed better for first-time buyers in Edmonton?
It depends on your timeline and risk tolerance. Variable often starts below fixed, by 50 basis points in our example, and a lower break penalty helps if you move sooner than planned. However, if you’re buying at your maximum and can’t absorb payment swings, fixed offers safety.
What happens to my variable rate if the Bank of Canada raises rates?
Each 0.25% BoC rate increase raises your variable rate by the same amount. On a $450,000 mortgage at our example variable rate, that’s roughly $62/month per quarter-point hike. If the BoC raised rates by a full 1.00%, your payment would increase by approximately $253/month. If you have a fixed-payment variable, your payment may stay the same while more of it goes to interest. The stress test qualified you at a rate 2% above your contract rate or 5.25%, whichever was higher.
Can I switch from variable to fixed mid-term?
Yes, most lenders allow you to convert from variable to fixed at any time without penalty. However, you’ll lock into the lender’s posted fixed rate at the time of conversion, not the discounted rate you’d get as a new borrower. That can be well above the best rate a new borrower would get, so ask your lender how it sets the conversion rate before you rely on it.
Do variable and fixed mortgages qualify differently under the stress test?
Both face the same stress test formula: contract rate + 2% OR 5.25%, whichever is higher (OSFI, 2024). But because variable rates start lower, they produce a lower qualifying rate: 6.25% against 6.75% at our example rates.
Why do most Canadians still choose fixed if variable saves more money historically?
Behavioural finance. The CMHC 2025 Mortgage Consumer Survey found 62% chose fixed (CMHC, 2025). Loss aversion — the pain of a rate increase — is psychologically about twice as powerful as the satisfaction of a rate decrease. Fixed rates sell certainty, and certainty has emotional value that doesn’t show up in spreadsheets. Neither choice is irrational; they just optimise for different things.
