Fixed vs Variable Mortgage: Which Is Right for You?

Whether you're applying for your first mortgage, looking at your renewal options, or switching lenders, one of the first questions you'll consider is whether to choose a fixed or variable rate. While there is no one-size-fits-all solution, your choice will be based on your personal risk tolerance and financial stability.

If you’re renewing your mortgage in 2026, this article will help you understand how each mortgage rate type works, what the trade-offs are, and how to decide which one fits your financial situation.

Fixed vs Variable Mortgage at a Glance

What Is a Fixed-Rate Mortgage?

A fixed-rate mortgage locks in your interest rate for the full length of your mortgage term, whether that’s one year or five. Your rate won't change, and neither will your monthly or bi-weekly mortgage payment.

Lenders set fixed rates based on Government of Canada bond yields, rather than the Bank of Canada’s rate.  Because they move independently, a fixed rate acts like insurance: your rate stays locked in, protecting you if market conditions change. Your lender then adds a profit margin on top, and that becomes your mortgage rate.

What it means for you is simple. When you lock in your mortgage, you typically pay a slightly higher rate at the time of lock-in than you would for a consistent rate you can plan around, regardless of how rates change over your term. For example, if you lock in five years at 3.5%, you keep paying 3.5% until renewal, even if rates hit 5%. The consistency can help make a sustainable spending plan far easier to stick to.

What Is a Variable-Rate Mortgage?

A variable-rate mortgage is tied to your lender's prime rate, which moves with the Bank of Canada's overnight policy rate. Lenders quote your contract as "prime plus" or "prime minus" a set percentage. That amount stays locked for your term, but the prime rate itself can change up to eight times a year when the Bank of Canada announces rate decisions.

In Canada, variable-rate mortgages come in two forms:

• Variable-rate, fixed-payment mortgage (VRM): Your monthly payment stays the same. When rates rise, more of it goes to interest and less comes off the balance. This stretches your amortization period so you pay the mortgage for longer than planned. If rates drop, more of your payment goes toward the principal.
• Adjustable-rate mortgage (ARM): The payment itself moves with prime. Your principal portion stays the same, but the interest portion adjusts automatically. Your monthly bill goes up or down in real time, but you avoid the risk of falling behind on your amortization. To see if this type of mortgage is good for you, add 1-2% to the estimated monthly bill. If you can afford it, it might be a suitable option for you.

What Is a Trigger Rate?

If you have a variable-rate, fixed-payment mortgage, there's one number you should know: your trigger rate.

The trigger rate is the point where your monthly payment can no longer cover the interest on your loan. Once you hit it, zero dollars go toward your principal balance, and your mortgage starts growing instead of shrinking—a process called negative amortization.

If you reach it, your lender will typically offer three options:

1. Increase the regular payment to cover the new interest and continue the principal repayment.
2. Make a lump-sum payment toward the principal to reduce the balance.
3. Convert to a fixed-rate mortgage for the remainder of the term.

Hitting a trigger rate can mean a real change in your monthly costs.   The best thing you can do is be aware of how close you are to hitting your trigger rate. To understand this , check your regular mortgage statements for your ratio of interest to principal in your payments , and ask your lender to warn you when you're getting close to your trigger rate.

Also, mortgage payments aren’t the only expense affected by changes in interest rates. Other debt, like lines of credit and credit card balances, can get more expensive, too. It helps to know how interest rate hikes affect your debt across the board.

Prepayment Penalties: Fixed vs Variable

Most mortgages are closed, which means you've committed to the full term (typically between 1 and 5 years). If you pay it off early, your lender charges a penalty. People usually need to pay this penalty when they sell, refinance, or switch lenders.

Variable-rate penalty: Three months of interest. On a $300,000 balance at 4%, that works out to about $3,000. 

Fixed-rate penalty: The greater of three months' interest or the interest rate differential (IRD). The IRD measures the gap between your original contract rate and what your lender could earn lending that money out again. This gap depends on your lender. 

Here's how the penalties compare on the same $300,000 balance at 4% with 36 months remaining. These are only illustrations, so ask how your lender calculates it before you sign.

The difference is dramatic. If there's any chance you'll need to break your mortgage early, the penalty structure should factor into your decision from the start.

How to Choose Between a Fixed and Variable Mortgage

Picking the right mortgage type starts by understanding what your household actually spends.

Both rate types come with a built-in buffer if you’re buying, refinancing, or borrowing more: the federal mortgage stress test requires you to qualify at either 5.25% or your contract rate plus 2%, whichever is higher. However, the stress test isn’t required if you're renewing with your current lender. It also only looks at your debt obligations, not your other spending, like groceries, childcare, utilities, or the other costs that determine what you can afford.

Your mortgage payment is a big expense, but it’s not your only one. The best way to plan is to build a realistic, sustainable spending plan that accounts for your full monthly picture, including your mortgage. Remember the ABCs: 

• Analyze what's coming in and going out.
• Brainstorm ways to raise income or cut costs.
• Change two or three things you'll stick to.

If you're preparing for mortgage renewal, check how much mortgage you can afford at today's rates, not the ones you signed at.

Mike Bergeron, Counselling and Client Services Manager at Credit Canada, notes: "One of the biggest misconceptions I've seen is the belief that a variable-rate mortgage will always be the cheaper option because it typically starts with a lower interest rate than a fixed mortgage. Canadians saw this firsthand between 2022 and 2023, when the Bank of Canada raised interest rates at the fastest pace in decades. For households already carrying other debt, this added pressure reduced their ability to manage credit cards, loans, and savings, often leading to increased financial strain."

Working with an experienced mortgage broker can help you better understand your options when it comes to choosing the right type of mortgage.

When a Fixed Rate Makes Sense

A fixed rate is a strong fit when:

• Your monthly cash flow is tight, with little room to absorb even a $200 increase.
• You're carrying a high mortgage balance relative to your income.
• You plan to stay in the property for the full mortgage term (avoiding the expensive IRD penalty)

When a Variable Rate Makes Sense

A variable rate works well when:

• You have flexible cash flow or emergency savings to absorb a 1-2% rate swing without financial strain.
• Economic indicators and Bank of Canada forecasts point to falling rates.
• You plan to sell or refinance before the end of your mortgage term. Terms can be as short as two to four years, so be realistic.

If money is already tight, Bergeron says to start somewhere other than the rate. "I encourage clients to look beyond the interest rate and ask a more important question: Can my budget comfortably handle this mortgage payment—not just today, but if my circumstances change?" he says. "For clients already carrying debt or living paycheque to paycheque, payment stability can be more valuable than chasing a slightly lower rate."

Have Variable or Fixed Rates Performed Better Historically?

More often than not, variable has won. 

A 2001 York University study covering about half a century of Canadian data found variable borrowers paid less interest 85% to 90% of the time. The argument is that fixed-rate borrowers pay a premium to their bank for the certainty of predictable payments, and the study shows that taking on rate fluctuation risk has been well rewarded in the long run.

However, a fast run of rate increases can erase the advantage entirely. For example, between 2022 and 2023, the Bank of Canada raised its policy rate from 0.25% to 5.00%, and people who had signed at pandemic-low rates saw their mortgage payments jump by hundreds or even thousands of dollars a month.

And, if you’re already struggling to pay off debt, a variable mortgage may not be the right solution, according to Bergeron. "For households already carrying other debt, this added pressure reduced their ability to manage credit cards, loans, and savings, often leading to increased financial strain."

What Is a Hybrid Mortgage in Canada?

A hybrid mortgage splits your total loan into two portions: one at a fixed rate and one at a variable rate, so you get some stability and some upside. When rates rise, the fixed portion keeps part of your payment stable. When rates drop, the variable portion captures immediate savings.

The trade-off is complexity. Each part can have its own maturity date and penalty, so breaking or refinancing a hybrid mortgage early can mean paying multiple fees. That can lock you into your current lender unless you're willing to cover the costs to exit both contracts.
