Fixed vs Variable Mortgage in Canada: The 2026 Decision Guide

The Question That Keeps Borrowers Up at Night

If you're shopping for a mortgage in 2026, someone has already asked you: "So, are you going fixed or variable?"

It's a fair question — and one that can mean tens of thousands of dollars over the life of your mortgage. But here's the thing most guides won't tell you: the "right" answer depends less on where rates are today and more on how your household handles financial surprises.

Let's walk through exactly how each option works, what today's numbers actually look like, and a decision framework you can use with confidence.

Where Rates Stand Right Now

After the Bank of Canada's aggressive cutting cycle through 2024–2025 — bringing the overnight rate from 5.00% down to 2.75% — the rate landscape has shifted dramatically. As of March 2026:

What this means: Variable rates are now cheaper than fixed — the best 5-year variable sits at 3.45% versus 3.74% for the best 5-year fixed. That 0.29% spread is meaningful on a large mortgage, but narrow enough that the decision isn't purely about cost anymore.

How Fixed Rate Mortgages Actually Work

With a fixed rate, the interest rate on your mortgage doesn't change for the entire term — typically 5 years. Your payment stays identical from month 1 to month 60.

Where fixed rates come from

Fixed mortgage rates are tied to Government of Canada bond yields, not the Bank of Canada's overnight rate. When bond investors expect steady or lower growth, bond yields drop — and fixed rates follow. When inflation fears rise, bond yields climb, and fixed rates go up.

This is why fixed rates sometimes move in the opposite direction of the Bank of Canada's rate announcements. In late 2025, the BoC was cutting its overnight rate, but 5-year bond yields actually rose on inflation concerns — pushing fixed rates sideways.

The real cost on a $500K mortgage

Let's say you lock in at 3.74% fixed on a $500,000 mortgage, 25-year amortization:

• Monthly payment: $2,561
• Total interest over 5 years: $86,630
• Principal paid after 5 years: $67,030
• Balance at renewal: $432,970

Your payment never changes. If the BoC cuts rates three more times? You still pay $2,561. If rates spike back up? You still pay $2,561. That predictability is worth real money to a lot of families.

When fixed makes the most sense

• You're stretching to qualify and can't absorb a payment increase
• Your household runs on a tight monthly budget
• You sleep better knowing exactly what your housing costs will be
• You might need to break the mortgage before term end (penalties are calculable upfront with a fixed)

How Variable Rate Mortgages Actually Work

With a variable rate, your interest rate moves with the lender's prime rate, which tracks the Bank of Canada's overnight rate. Most variable mortgages are quoted as "prime minus" a discount — for example, prime − 1.00%.

With prime at 4.45% today, that gives you an effective rate of 3.45%.

Two flavours of variable

There's an important distinction most people miss:

Adjustable Rate Mortgage (ARM): Your payment changes every time prime moves. Rate goes down? Your payment drops. Rate goes up? Your payment increases.

Variable Rate Mortgage (VRM): Your payment stays the same, but the split between principal and interest shifts. If rates rise, more of your payment goes to interest and less to principal. This is where "trigger rates" come from — the point where your payment doesn't even cover the interest.

Most big banks offer VRMs. Most brokers can get you ARMs. If you're going variable, an ARM is generally the better choice because you always know where you stand.

The real cost on a $500K mortgage

Same $500,000 mortgage at 3.45% variable (prime − 1.00%):

• Monthly payment: $2,484 ($77/month less than fixed)
• Total interest over 5 years if rate stays flat: $79,040
• But if BoC cuts 0.25% more: Total interest drops to ~$75,900
• And if BoC cuts a full 0.50%: Total interest drops to ~$72,700

So the variable starts cheaper and gets better if the BoC delivers more cuts. The question is whether you can handle the scenario where rates go the other way.

When variable makes the most sense

• You have cash reserves or flexible income that can absorb payment swings
• You believe the Bank of Canada has more cuts ahead
• Your mortgage is smaller (the dollar impact of rate changes is lower)
• You want the lowest penalties if you break early (typically just 3 months' interest)

The Math That Actually Matters

Let's run four scenarios on that $500K mortgage over a 5-year term:

The takeaway: With variable currently 0.29% below fixed, variable has a clear head start. Even if rates rise moderately, the initial savings buffer means fixed only wins in a significant rate-hike scenario. With most economists expecting stable-to-lower rates through 2026, the math tilts toward variable right now.

The Penalty Factor Nobody Talks About

Here's something that changes the math completely: what happens if you need to break your mortgage early?

Life happens. You get a job transfer, a divorce, an inheritance that lets you buy a bigger place. About 60% of Canadians break their mortgage before the 5-year term is up.

Fixed rate penalties

The penalty is the greater of:

• 3 months' interest, OR
• The Interest Rate Differential (IRD)

The IRD is where it gets painful. If you locked in at 3.74% and current rates have dropped to 3.24%, the bank calculates the "loss" over your remaining term. On a $433K balance with 2 years left, that IRD penalty could be $8,000–$14,000.

Variable rate penalties

The penalty is almost always just 3 months' interest. On that same $433K balance at 3.45%, that's roughly $3,735.

That's a potential $4,000–$10,000 difference in penalties. If there's any chance you'll move, refinance, or restructure in the next 5 years, this alone could tip the decision toward variable.

A Decision Framework You Can Actually Use

Forget the spreadsheets for a minute. Answer these five questions honestly:

1. What's your financial cushion?
If your mortgage payment went up $200/month tomorrow, would that cause stress? If yes → fixed.

2. How long are you staying?
If you might move or refinance within 3 years, the penalty math favours variable regardless of rate direction.

3. What's your mortgage size?
On a $250K mortgage, the difference between fixed and variable might be $3,800 over the term. On a $700K mortgage, it could be $10,600+. Bigger mortgages magnify the variable advantage and the variable risk.

4. What's your gut telling you about rates?
You don't need a PhD in economics. If you think the economy is slowing and the BoC will keep cutting, variable has tailwinds. If you think inflation could flare up again, fixed is your hedge.

5. Can you sleep at night?
Seriously. The psychological cost of watching your rate float is real. Some people check the BoC announcement every six weeks like it's an exam result. If that's you, the "insurance premium" of a fixed rate is money well spent.

What About Shorter Terms?

You don't have to choose a 5-year term. In fact, a 3-year fixed at 3.69% might be a smart middle ground:

• You get rate certainty for 3 years
• You're paying just 0.24% more than today's best variable
• Your IRD penalty window is shorter if you break early
• You renew sooner, when rates may be even lower

Right now, 3-year fixed rates are actually lower than 5-year fixed rates (3.69% vs 3.74%) — an unusual situation that suggests the market expects rates to stay low. That makes the 3-year fixed a particularly attractive option in spring 2026.

The Historical Record

A Bank of Canada study looking at data from 1950–2007 found that variable rate borrowers came out ahead roughly 90% of the time over any given 5-year period. That's a powerful stat.

But it comes with caveats:

• The study ended before the 2022–2023 rate shock, where variable borrowers saw rates jump from 1.5% to 7%+ in 18 months
• "Coming out ahead" doesn't account for the stress of payment volatility
• Past rate cycles don't predict future ones

The historical edge is real, but it's not a guarantee. Think of variable as a bet that usually pays off — but when it doesn't, it can sting.

Our Take for Spring 2026

With prime at 4.45%, the best variable at 3.45%, and fixed rates at 3.74%, variable has both a mathematical and directional edge right now. You start with a lower rate and stand to benefit if the BoC delivers another cut or two.

But here's what we tell our clients: the best rate type is the one that lets you focus on the rest of your life instead of refreshing rate forecasts every morning.

If the potential savings of variable ($7,500–$14,000 over 5 years) would meaningfully change your financial picture, it's worth the uncertainty. If not, lock in at 3.74% and forget about it.
