Fixed vs Variable Mortgage in 2026 — Which Is Better Right Now?

By ClearKey  ·  March 2026  ·  Based on current Bank of Canada rate of 2.25%

The fixed vs variable debate never really goes away — and for good reason. The decision can mean the difference of tens of thousands of dollars over a mortgage term. Here's what the numbers actually show in today's rate environment, and the framework most mortgage professionals use to make the call.

Where Rates Stand in 2026

The Bank of Canada held its overnight rate at 2.25% at its March 2026 meeting — the third consecutive hold after an aggressive cutting cycle that brought the rate down from 5.00% in mid-2024. Prime rate sits at 4.45%.

In practical terms for mortgage borrowers:

Current Rate Environment — March 2026

Bank of Canada overnight rate 2.25%
Prime rate 4.45%
Typical 5-year fixed (discounted) ~4.59%
Typical variable rate (prime − 0.50%) ~3.95%
Current spread (fixed vs variable) ~0.64% in favour of variable

A 0.64% spread sounds modest, but on a $600,000 mortgage over a 5-year term, it adds up to approximately $19,000 in additional interest paid on the fixed rate — assuming rates don't change. The question, of course, is whether they will.

How Fixed Rate Mortgages Work

A fixed rate mortgage locks your interest rate for the entire term — typically 1, 2, 3, or 5 years. Your payment amount doesn't change during the term regardless of what the Bank of Canada does with its overnight rate.

Fixed rates in Canada are priced off Government of Canada bond yields, not the overnight rate. This is an important distinction — fixed rates can move independently of the BOC rate, and often do. When bond markets expect future rate cuts, fixed rates can fall even before the BOC acts. Conversely, if bond yields rise due to inflation concerns, fixed rates can climb even while the overnight rate is unchanged.

The most common fixed term in Canada is the 5-year fixed, which has historically been chosen by roughly 60-70% of Canadian mortgage borrowers for the payment certainty it provides.

How Variable Rate Mortgages Work

A variable rate mortgage fluctuates with the prime rate, which is set by Canadian banks at the overnight rate plus 2.70%. When the Bank of Canada cuts rates, prime falls and your variable rate mortgage costs less. When rates rise, you pay more.

There are two types of variable rate mortgages in Canada:

The Historical Record — Variable Has Usually Won

Research by Dr. Moshe Milevsky, a York University finance professor, found that over a 50-year period, Canadian borrowers who chose variable rate mortgages saved money approximately 88% of the time compared to 5-year fixed mortgages. This is the most frequently cited piece of research in the fixed vs variable debate.

The logic is straightforward: variable rates start lower than fixed rates, and the Bank of Canada spends more time cutting rates than hiking them over long periods. Borrowers who accept the short-term uncertainty of a variable rate tend to come out ahead over full amortization periods.

However, this historical advantage doesn't guarantee future results. Borrowers who chose variable in 2022 experienced painful payment increases as the BOC hiked rates by 475 basis points in 18 months — one of the most aggressive tightening cycles in Canadian history.

The 2022-2023 Exception

Variable rate borrowers who entered in 2021-2022 at historically low rates faced severe payment shocks as the BOC hiked aggressively. A $600,000 variable mortgage that started at 1.45% in early 2022 reached nearly 6.70% by late 2023 — a monthly payment increase of over $1,800. This is the risk that fixed rate certainty is designed to protect against.

The Key Decision Factors in 2026

The right choice depends on your personal circumstances more than on any market prediction. Here are the questions that matter most:

For Fixed Rate

Choose Fixed If...
Certainty matters more than savings
  • You are at or near your maximum qualifying amount
  • A payment increase of $300-$500/month would cause financial stress
  • You have a single income household
  • You are self-employed with variable monthly income
  • You believe rates will rise before your renewal
  • You value being able to budget precisely
Choose Variable If...
You can absorb payment changes
  • You have meaningful financial cushion beyond your mortgage payment
  • You could comfortably handle a 1-2% rate increase
  • You believe rates will stay flat or fall
  • You may need to break your mortgage early (variable penalties are far lower)
  • You are buying a property you may sell within 3-4 years
  • You have dual incomes providing payment stability

The Penalty Calculation — Often Overlooked

One factor that consistently gets underweighted in the fixed vs variable decision is the prepayment penalty when breaking a mortgage before the term ends.

Variable rate mortgages always use a 3-month interest penalty — simple, predictable, and typically modest. On a $600,000 variable mortgage at 3.95%, the penalty is approximately $5,900.

Fixed rate mortgages use the greater of 3-month interest or the Interest Rate Differential (IRD). At major banks, IRD penalties can be $15,000 to $40,000+ depending on how far rates have moved since you signed. This is because Big 6 banks calculate IRD using their posted rate minus your discounted rate — a gap that can be 1.5-2.5% — rather than the actual market rate movement.

If there is any chance you will sell your home, refinance, or switch lenders before your term ends, the lower variable penalty is a significant financial advantage. You can estimate your penalty with ClearKey's penalty calculator before making a decision.

Comparing the Two Over a 5-Year Term

$600,000 Mortgage, 25-Year Amortization — 5-Year Total Interest

Fixed rate (4.59%) — 5yr total interest ~$127,800
Variable rate (3.95%, rates unchanged) — 5yr total interest ~$109,700
Savings with variable (rates unchanged) ~$18,100
Variable breaks even with fixed if BOC hikes ~1.30% of rate increases

The variable rate stays ahead of the fixed rate unless the Bank of Canada raises rates by more than approximately 1.30% over the 5-year term. Given that the BOC is currently on hold and most economists expect rates to stay flat or potentially fall slightly in 2026, the variable rate starts with a meaningful mathematical advantage.

What About Shorter Fixed Terms?

A 3-year fixed rate of approximately 4.39% narrows the gap with variable considerably. For borrowers who want fixed-rate certainty but don't want to lock in for a full 5 years, a 3-year fixed is worth considering — particularly if you believe rates will move significantly (in either direction) before your next renewal.

The tradeoff: shorter terms mean more frequent renewals, which requires more active management but also more opportunities to benefit from rate changes.

The Bottom Line

There is no universally correct answer to fixed vs variable — any advisor who tells you otherwise is oversimplifying. The right choice depends on your financial cushion, risk tolerance, likelihood of breaking the mortgage early, and view on the direction of rates.

What the math does show clearly in 2026: variable rates have a meaningful starting advantage of approximately 0.64% over 5-year fixed rates, the BOC is on hold with no rate hikes anticipated in the near term, and variable penalties are dramatically lower than fixed penalties for borrowers who may need flexibility.

For borrowers who prioritize certainty and are near their qualifying limit, fixed rates remain the right choice. For borrowers with financial flexibility who value the lower starting rate and penalty protection, variable makes a strong case in the current environment.
