Fixed vs. Variable Rate Mortgage at Renewal: The Complete 2026 Canadian Guide

The choice between a fixed and variable interest rate is one of the most consequential decisions a Canadian mortgage holder makes at renewal — and it's one where there's no universally correct answer. The right choice depends on your financial situation, risk tolerance, the current rate environment, and your expectations about where rates are headed. This comprehensive guide breaks down every aspect of this decision so you can make a confident, informed choice.

Fixed Rate Mortgages at Renewal

A fixed rate mortgage locks in your interest rate for the entire duration of your term. Whether you choose a 1-year, 3-year, or 5-year fixed term, your rate — and therefore your principal-and-interest payment amount — will not change regardless of what the Bank of Canada does with its policy rate during that period.

Advantages of Fixed Rate

• Predictability: Your payment is the same every period. This makes budgeting simpler and eliminates payment shock risk.
• Protection from rate increases: If rates rise after you lock in, you're shielded for the duration of your term.
• Sleep factor: Many homeowners simply sleep better knowing exactly what their mortgage payment will be for the next several years.
• Currently competitive: With the BoC rate at 2.25% and bond yields relatively stable in early 2026, fixed rates are at reasonable levels compared to 2022–2023.

Disadvantages of Fixed Rate

• Breaking penalty: If you need to break a fixed mortgage mid-term (to sell, refinance, or port), you'll face an Interest Rate Differential (IRD) penalty — which at major banks can be extremely large. This is covered in detail below.
• Higher rate than variable (often): Fixed rates typically carry a premium over variable rates because you're paying for certainty. When rates are expected to fall, you may give up savings by locking in.
• Opportunity cost: If rates drop significantly after you lock in, you're stuck at the higher rate unless you pay to break the mortgage.

Variable Rate Mortgages at Renewal

Variable rate mortgages fluctuate with your lender's prime rate, which in turn follows the Bank of Canada's overnight target rate. When the BoC raises rates, variable mortgage holders see an increase; when the BoC cuts, they benefit. But not all variable mortgages work the same way — there are two structurally different types that many Canadian borrowers don't fully understand.

ARM vs. VRM: Two Types of Variable Rate Mortgages

The Trigger Rate Explained (VRM Only)

The trigger rate is a concept that applies only to VRM (Variable Rate Mortgage) products where your payment stays constant. The trigger rate is the point at which your fixed payment no longer covers the full interest owing for that period. When this happens, your lender will typically:

1. Notify you that you've hit your trigger rate
2. Require you to increase your payment amount to re-cover the interest
3. In some cases, add the uncovered interest to your principal balance (negative amortization)

During the Bank of Canada's aggressive 2022–2023 rate hiking cycle — which took the overnight rate from 0.25% to 5.00% in roughly 18 months — tens of thousands of Canadian VRM holders hit their trigger rates. Many were required to significantly increase their monthly payments or make large lump-sum payments. This was a major source of financial stress and is now a well-known risk that borrowers choosing VRM products must understand and plan for.

Historical Context: Which Has Performed Better Over Time?

Multiple academic studies — most notably the often-cited research by York University finance professor Moshe Milevsky — have found that variable rate mortgages have outperformed fixed rates over long periods in Canada. Historically, taking the variable rate has been the winning strategy approximately 80–90% of the time over rolling 5-year periods.

The logic is straightforward: fixed rates carry a "certainty premium" that you pay to lock in your rate. Variable rates benefit from the full pass-through of BoC cuts, and the BoC has spent far more time cutting rates than raising them over the past three decades.

However — and this is critical — the 2022–2023 rate hiking cycle was the exception that proved the rule. Borrowers who locked in a fixed rate at 2.25–2.75% in 2020 or 2021 significantly outperformed those in variable rate mortgages who saw their rates climb to 6–7% over the same period. Many variable rate holders who bought during the pandemic with VRMs saw their mortgage payments double.

The lesson is not that one type is always better, but that the rate environment at the time of your decision matters enormously. Historical averages are informative, but they don't predict your specific 5-year window.

The Penalty Difference: Fixed vs. Variable

This is one of the most practically important — and least understood — distinctions between fixed and variable rate mortgages. The penalty for breaking your mortgage mid-term is calculated differently for each type, and the difference can be enormous.

Variable Rate Penalty: 3 Months' Interest

For virtually all variable rate mortgages in Canada, the penalty for breaking mid-term is simply 3 months' interest on your outstanding balance. This is relatively predictable and modest. On a $500,000 mortgage at 4.45%, 3 months' interest is approximately $5,563. Painful, but manageable.

Fixed Rate Penalty: IRD (Interest Rate Differential)

Fixed rate mortgages at major banks (the Big 6) are subject to an Interest Rate Differential (IRD) penalty when broken mid-term. The IRD calculates the difference between your contract rate and the lender's current rate for the remaining term, multiplied by your outstanding balance and remaining months.

In plain language: if you locked in at 5.25% and rates have since fallen to 3.75%, and you have 3 years left in your term, the bank calculates the revenue they'd lose from the rate drop and charges you that difference as a penalty. This can result in prepayment penalties of $15,000, $25,000, or even $40,000+ on large mortgages with major banks.

The Rate Spread Concept

The spread between fixed and variable rates is a key metric when deciding which to choose at renewal. A small spread (e.g., variable at 4.45% vs. 1-year fixed at 4.55%) suggests little incentive to take variable. A large spread (e.g., variable at 4.00% vs. 5-year fixed at 5.25%) tilts the math toward variable, assuming rates don't rise sharply.

As of early 2026, with the BoC rate at 2.25% and prime rate at 4.45%, variable rate mortgages (typically prime minus a discount) are priced around 4.20–4.45%, while 5-year fixed rates are in the 4.50–4.80% range depending on the lender. The spread is modest but positive for variable — suggesting variable has a slight edge if you believe rates are more likely to hold or fall than rise significantly.

The 2026 Rate Environment

The Bank of Canada began cutting its overnight rate in June 2024 and continued through 2025, bringing the rate from its peak of 5.00% (July 2023) to 2.25% by January 2026. This represents a 275-basis-point easing cycle — one of the most aggressive rate-cutting sequences in BoC history.

Fixed rates are driven not by the BoC's overnight rate but primarily by Government of Canada bond yields — particularly the 5-year bond yield. Bond markets had already priced in many of the BoC cuts ahead of time, which is why 5-year fixed mortgage rates didn't fall as dramatically as prime-linked variable rates.

As of March 2026, most economists and market forecasters expect the BoC to hold rates relatively stable through 2026, with modest cuts possible if inflation remains subdued. This makes the fixed vs. variable decision relatively balanced — fixed rates offer modest certainty premium, while variable offers slight rate advantage with the potential for further BoC cuts.

Shorter-Term Fixed as a Middle Ground

Many borrowers overlook the strategic value of shorter fixed-rate terms at renewal. A 2-year or 3-year fixed provides the predictability of a fixed rate while allowing you to return to the market sooner — potentially locking into even lower rates if the environment continues to improve.

In a declining rate environment, shorter terms are particularly valuable. In early 2026, 2-year fixed rates from competitive lenders are often priced close to 5-year fixed rates — sometimes even lower — making them an attractive proposition: you get predictability for 24 months while preserving the flexibility to reassess when your term ends.
