5-Year Fixed vs Variable Mortgage Canada 2026: Which Costs Less?

If you’re shopping for a mortgage in 2025 or renewing in early 2026, the fixed-versus-variable question deserves more than a gut-feel answer – and right now, it’s genuinely hard to call. Rates have shifted considerably over the past three years, the Bank of Canada has been cutting, and informed people still disagree on where things settle. What follows works through the actual math, the historical record, and the specific conditions under which each option tends to cost less, so you have something concrete to reason from rather than just a headline rate to react to.

Where Canadian Mortgage Rates Actually Stand Right Now

As of mid-2025, the Bank of Canada’s overnight policy rate sits at approximately 2.75% after a series of cuts from the 5.00% peak reached in mid-2023. That shift has already pulled variable mortgage rates down meaningfully, but five-year fixed rates have their own dynamic — they track Government of Canada five-year bond yields, which respond more to inflation expectations and U.S. economic signals than to Bank of Canada decisions alone.

Here is a realistic snapshot of what well-qualified borrowers are seeing at major lenders and brokers in mid-2025:

With Prime currently at 4.95%, the best variable offers are sitting in the 4.05%–4.45% range — which means variable is already priced below comparable fixed rates for many borrowers. That gap is the starting point for any honest break-even analysis.

One important note: the mortgage stress test qualifying rate for uninsured mortgages remains at the contract rate plus 2%, with a floor of 5.25%. Most borrowers stress-testing a variable at 4.25% will qualify at 6.25%. Keep that in mind if your approval is tight.

The Break-Even Math: How Many Rate Cuts Does Variable Need?

The break-even question is simple to frame: how much does the Bank of Canada need to cut (or raise) for your variable rate to cost the same total interest as the fixed rate over five years?

A worked example

Assume a $500,000 mortgage, 25-year amortization, with these two options:

• Option A – 5-Year Fixed at 4.59%
• Option B – 5-Year Variable starting at 4.25% (Prime minus 0.70%)

At 4.59% fixed, your monthly payment is approximately $2,762. Over 60 months, you pay roughly $68,800 in interest and reduce your principal by about $27,700.

At 4.25% variable (assuming no further rate changes for the full five years), your monthly payment is approximately $2,695. Total interest over 60 months comes to roughly $63,200 — about $5,600 less.

That $5,600 gap is your buffer. For variable to break even with fixed, rates would need to rise enough over the term to eliminate that difference. A rough calculation: if the Bank of Canada raises rates by 1.00% and holds for roughly 24 months of the term, variable borrowers would lose most of that advantage. A 1.50% hike held for the full term would put variable meaningfully behind.

Conversely, if the Bank of Canada cuts another 0.50%–1.00% before mid-2026 as some forecasters expect, the variable advantage widens further.

What History Actually Shows About Fixed vs Variable

The Moshe Milevsky study from 2001 is still frequently cited: over most 15-year rolling periods in Canada, variable-rate mortgages have outperformed five-year fixed mortgages roughly 70%–80% of the time on a pure cost basis. The reason is structural — lenders price fixed rates with a premium for the certainty they provide, and that premium usually exceeds the average difference in rates over time.

But the recent cycle is a useful counterexample. Borrowers who chose variable rates in 2021 and 2022 experienced the fastest Bank of Canada tightening cycle in four decades. Someone who locked in a five-year fixed at 1.79% in early 2021 came out dramatically ahead of a variable borrower who rode Prime from 2.45% all the way to 7.20% by late 2023. The historical “variable usually wins” rule held over 20 years — it absolutely did not hold over that specific 2021–2024 window.

The lesson is not that variable is bad. The lesson is that the historical advantage is a long-run probability, not a guarantee for any specific five-year window.

Bank of Canada Policy Outlook and What It Means for 2026

As of mid-2025, the Bank of Canada has cut its policy rate from 5.00% to 2.75% through a series of reductions starting in June 2024. Most major bank economists are forecasting the overnight rate settling somewhere in the 2.50%–3.00% range, with cuts largely complete or near complete. The Bank’s own neutral rate estimate is 2.25%–3.25%, so we are already in or very near neutral territory.

What this means practically:

• Further large cuts are less likely unless Canada enters a recession or trade conditions deteriorate significantly (tariff-related economic slowdown is a real risk given U.S.-Canada trade tensions).
• Rate hikes are also unlikely in the near term, barring a significant inflation resurgence.
• Variable borrowers are not riding a rate-cut wave the way they would have been in 2009 or 2020. Most of the cut cycle is probably already priced in.

This changes the fixed-versus-variable calculus compared to, say, late 2023. At that point, variable borrowers had significant upside from expected cuts. Today, variable borrowers are betting more on stability or modest additional cuts rather than a dramatic reduction in their rate. Fixed borrowers are locking in at rates that are historically mid-range — not the generational lows of 2020–2021, but not the painful highs of 2023 either.

Penalties, Prepayments, and the Hidden Cost of Fixed Mortgages

Rate comparisons alone miss a significant part of the picture: what happens if your life changes during your mortgage term?

IRD penalties on fixed-rate mortgages

Breaking a fixed-rate mortgage early at a major Canadian bank typically triggers an Interest Rate Differential (IRD) penalty — not just three months’ interest. IRD calculations can produce penalties of $15,000–$30,000 or more on a $500,000 mortgage depending on how far rates have moved. This is a real and often underestimated risk for borrowers who might sell, refinance, or separate within five years.

Variable-rate penalties

Variable-rate mortgages, by contrast, almost always have a maximum break penalty of three months’ interest. On a $500,000 mortgage at 4.25%, that is roughly $5,300. If there is any realistic chance you will break your mortgage before the five-year term ends — job relocation, growing family, relationship change — the variable penalty advantage is worth real money.

One practical note: monoline lenders and credit unions often calculate IRD penalties more favourably than the Big Six banks. If you are going fixed, it is worth comparing the penalty calculation methodology, not just the rate.

Honest Takeaway: When Fixed Makes Sense and When Variable Does

There is no universally correct answer. Here is a plain-language breakdown of which option fits which situation in the current environment.

5-Year fixed is probably the right call if:

• Your budget is tight and payment certainty genuinely matters to your household — a rate spike would create real financial stress, not just annoyance.
• You are confident you will stay in the property and keep this mortgage for the full five years (no anticipated sale, refinance, or major life change).
• You believe inflation will prove stickier than consensus expects, or that the Canadian economy will perform better than forecast — scenarios where rate cuts stall or reverse.
• You are a first-time buyer already stretched by home prices in markets like Toronto or Vancouver, where payment stability has direct budgeting value.

5-Year variable is probably worth considering if:

• You have a financial buffer — three to six months of mortgage payments in accessible savings — so a rate increase of 0.50%–1.00% does not threaten your household finances.
• There is a realistic chance you will sell or refinance within three to four years. The penalty difference alone may justify variable.
• You accept one more Bank of Canada cut is possible (bringing variable rates closer to the low 4% range or below), and you would benefit from that without needing to refinance.
• You are comfortable with month-to-month payment variation and have tracked how variable payments moved over 2022–2023 without being caught off guard.

When neither five-year option is ideal:

If you are genuinely uncertain about where you will be in two or three years, a three-year fixed rate (currently around 4.09%–4.59% at competitive lenders) often gives reasonable certainty with a shorter commitment. It is an option worth pricing out before defaulting to the five-year standard.

The fixed-versus-variable decision in 2026 is genuinely closer than it was in 2023, when the rate gap was much wider. Today it comes down to your personal risk tolerance, your specific life circumstances, and a realistic view of what the Bank of Canada is likely to do from a position already near neutral. Work through the numbers for your actual mortgage size, get quotes from at least one broker and one direct lender, and compare penalty methodologies alongside rates.
