It’s one of the first decisions buyers face after getting pre-approved. Fixed or variable? The question sounds simple. The answer is personal — and it depends on things that have nothing to do with trying to predict what the Bank of Canada will do next.
This is a plain-language breakdown of how each type actually works, what the real tradeoffs are, and the questions worth bringing to your mortgage professional. This is education — not financial advice — and the right answer for you should come from a licensed mortgage professional who knows your full financial picture.
The Core Difference
- →Rate doesn’t change for your term
- →Same payment every month
- →Unaffected by Bank of Canada decisions
- →Typically higher rate than variable at start
- →Higher penalty if you break early
- →Rate tied to lender’s prime rate
- →Payment or amortization adjusts as rates move
- →Moves with Bank of Canada decisions
- →Typically lower rate than fixed at start
- →Lower penalty if you break early
How a Fixed Rate Works
A fixed rate mortgage locks your interest rate for a set term — typically one to five years in Canada, with the three-year and five-year options being the most common. For the entire duration of that term, your rate doesn’t move. Your payment stays the same. What the Bank of Canada does with its overnight rate during that period has no effect on what you’re paying.
At the end of your term, you renew — and whatever rate environment exists at that point becomes your new starting point.
The appeal is straightforward. Certainty. You know your monthly payment for years at a time. You can budget accurately. You don’t think about rate announcements. You can use the mortgage calculator to lock in exactly what your payment looks like at a fixed rate before you ever speak to a lender.
The tradeoff is that fixed rates typically start higher than variable rates to account for the certainty premium. And if you need to break a fixed mortgage before the term ends — which more buyers do than expect, due to job changes, relationship changes, or upsizing — the penalty can be significant.
How a Variable Rate Works
A variable rate mortgage is tied to your lender’s prime rate — which moves in response to Bank of Canada decisions. When the Bank of Canada cuts its overnight rate, lenders typically reduce their prime rate shortly after. When the BoC raises rates, prime rises too.
Variable rates are typically expressed as prime plus or minus a spread that is set when you sign your mortgage. So if the prime rate is 2.25% and your mortgage is prime minus 0.50%, your rate is 1.75%.

There are two main types of variable mortgages in Canada. With an adjustable rate mortgage, your actual payment changes when prime moves. With a variable rate mortgage with fixed payments, your payment stays the same — but the split between principal and interest adjusts, which changes how quickly you pay down your mortgage.

The Penalty Difference — The Most Underestimated Factor
Most buyers don’t expect to break their mortgage early. Many do anyway — life changes, opportunities appear, circumstances shift. Understanding the penalty difference before you sign matters more than most people realize at the time of purchase.
| Mortgage Type | Early Break Penalty | Typical Size |
|---|---|---|
| Fixed Rate | Higher of: three months’ interest OR Interest Rate Differential (IRD) | Can be substantial — sometimes $10,000–$30,000+ |
| Variable Rate | Three months’ interest | Typically much lower and predictable |
The IRD calculation on a fixed mortgage measures the difference between your contracted rate and the current rate for the remaining term. When rates have fallen significantly since you locked in, that gap — multiplied by your outstanding balance and remaining months — can create a very large penalty number. Variable mortgage penalties are almost always just three months of interest, which is predictable and usually manageable.
If there’s any meaningful chance you might sell, refinance, or change your mortgage within the next few years — the penalty difference alone can outweigh the rate difference between fixed and variable.
Which Type Might Suit You Better
There is no universally correct answer. The right choice depends on your income stability, risk tolerance, how long you plan to hold the property, and how you respond emotionally to rate volatility. Here’s a general framework — not a recommendation.
Fixed might suit you if:
- Certainty matters more than saving money
- Your income is variable or seasonal
- You’re budgeting tightly and can’t absorb payment changes
- You plan to hold the property for the full term
- Rate announcements make you anxious
Variable might suit you if:
- You’re comfortable with some rate uncertainty
- You have stable income and a financial cushion
- You may sell or refinance within the term
- You understand how prime rate movements work
- Lower initial rate and lower penalties appeal to you
The Term Length Question
Whether you go fixed or variable, you also choose your term — how long until you renew. Shorter terms (one or two years) give you more flexibility but more frequent renewal exposure. Longer terms (four or five years) lock in your rate for longer but reduce flexibility.
Many buyers default to the five-year fixed because it’s familiar and heavily marketed. That doesn’t make it wrong — but it’s worth questioning whether it’s the right fit for your specific plans rather than just the path of least resistance.
What About a Hybrid Mortgage?
Some lenders offer hybrid or combination mortgages — splitting your mortgage balance between a fixed portion and a variable portion. You get partial certainty and partial exposure to rate movements. This can work well for buyers who genuinely want both, but it also adds complexity. If this option interests you, make sure your mortgage professional walks through the renewal and penalty mechanics clearly before you sign.
The fixed vs. variable decision doesn’t have a correct answer that works for everyone — it has a correct answer for your situation. The best thing you can do is bring these questions to a licensed mortgage professional, run the numbers for both scenarios, and make the choice that fits how you actually live and plan — not the one you think you’re supposed to make.

Frequently Asked Questions
What is a fixed rate mortgage in Canada?
A fixed rate mortgage locks your interest rate for a set term — typically one to five years. Your payment stays the same for the entire term regardless of what the Bank of Canada does with its overnight rate. At the end of the term you renew at whatever rate is available at that time.
What is a variable rate mortgage in Canada?
A variable rate mortgage is tied to your lender’s prime rate, which moves in response to Bank of Canada rate decisions. When the Bank of Canada cuts its overnight rate, prime typically drops and your variable rate falls with it. When the BoC raises rates, your variable rate rises. The rate is expressed as prime plus or minus a spread that is set at signing.
What are the penalties for breaking a fixed vs. variable mortgage early?
Breaking a fixed mortgage early typically triggers an Interest Rate Differential (IRD) penalty, which can be substantial — sometimes tens of thousands of dollars depending on how much rates have changed since you locked in. Breaking a variable mortgage early typically costs three months of interest, which is usually much lower and more predictable. This is one of the most important practical differences between the two products.
Is fixed or variable better in Canada right now?
There is no universal answer — it depends on your income stability, risk tolerance, plans for the property, and current rate environment. Variable rates have often been lower over the long term historically, but they come with uncertainty. Fixed rates provide certainty but typically cost more upfront. The right choice is the one that fits your specific financial situation. A licensed mortgage professional can run the numbers for both scenarios based on your actual mortgage amount.
What is a mortgage term vs. amortization in Canada?
The term is how long your current rate agreement lasts — typically one to five years — after which you renew at a new rate. The amortization is the total length of time it would take to pay off the full mortgage — typically 25 or 30 years. You’ll renew your mortgage multiple times over the life of the amortization period, each time at the rate available when you renew.
Can I switch from variable to fixed during my term?
Many lenders allow you to convert a variable rate mortgage to a fixed rate before the end of your term, typically at the fixed rate available at the time of conversion. The terms of conversion vary by lender. If you start a variable mortgage and rate uncertainty begins to affect you significantly, this is worth asking your lender about — though the conversion rate available at the time may or may not be more favourable than your original options.
