Fixed versus variable is treated as a bet on where rates are going. It shouldn’t be. Nobody — not your broker, not your bank, not the economists whose forecasts get revised every quarter — knows where prime lands in three years. What you can know is your own situation: how likely you are to break or change this mortgage before the term ends, how much payment movement you can absorb without losing sleep, and what the exit costs look like on each side. Those are knowable facts, and they decide this question far more reliably than a forecast does.
The single most under-discussed difference isn’t the rate at all. It’s what it costs to get out. Breaking a variable-rate mortgage almost always costs three months’ interest. Breaking a fixed can cost the interest rate differential — and on a real discharge statement we published, the IRD came in four times the three-months’ calculation. If there’s a meaningful chance your life changes mid-term, that gap matters more than the rate you started with.
| Fixed | Variable | |
| Rate certainty | Locked for the term | Moves with prime |
| Penalty to break | Greater of 3 months’ interest or IRD — often far larger | Almost always 3 months’ interest |
| Convert mid-term | No — you’re in it | Usually yes, to a fixed at then-current rates |
| Qualifying | Stress test applies | Stress test applies — identically |
| Best suited to | Fixed budgets, long horizons, low tolerance for movement | Files likely to change, sell, or refinance mid-term |
Notice how much of that table has nothing to do with which rate is lower. That’s the point of treating this as planning rather than prediction.
At any given moment there’s a spread between the best fixed and the best variable. That spread is what you pay for certainty — and framing it as a price makes the decision tractable.
Work an example. On a $600,000 mortgage with a 0.65% gap, choosing fixed costs roughly $3,900 more in interest over the first year — about $325 a month. That’s the premium. Now the only question worth asking: is $325 a month a fair price for not thinking about this again for five years?
For plenty of households the answer is a straightforward yes, and there is nothing unsophisticated about buying peace of mind. For others — particularly those with a real chance of moving, selling or refinancing before the term is out — that same $325 buys certainty they were never going to use, while the penalty structure quietly costs them far more on the way out. Neither answer is smarter. They’re answers to different situations.
What the gap can’t tell you is who wins. A wide gap means variable starts cheaper and has more room to rise before it loses. A narrow gap means the certainty is cheap. Both are facts about today’s pricing, not signals about tomorrow’s.
Here is the part that disappears when this gets framed as a bet: a variable mortgage is a more flexible contract, and that flexibility has a cash value which shows up exactly when life stops cooperating.
Think about what actually ends mortgages early. Not exotic events — ordinary ones:
None of that is unusual. In our own practice, roughly four out of five mortgages we fund are refinances or switches — people changing a mortgage they already have, not buying their first home. Mortgages get restructured far more often than a five-year contract implies, and the people who get hurt are the ones whose contract made leaving expensive.
Variable answers that in two ways. The penalty is almost always three months’ interest — a number you can estimate on the back of an envelope and absorb. And the conversion option runs one way, in your favour: you can move from variable to fixed mid-term, but never the reverse. Choosing variable keeps the door to fixed open all term. Choosing fixed closes the door to variable on day one.
That asymmetry is why we describe variable as the more flexible plan rather than the cheaper bet. You aren’t only buying today’s rate. You’re buying the right to change your mind — and for a great many households, that turns out to matter more than knowing the payment to the dollar for sixty months.
Which is not an argument that everyone should take variable. It’s an argument that “fixed is the safe one” is too simple. Fixed is safe against one risk — rate movement — and expensive against another: needing out. Whether that trade favours you depends entirely on which risk your life is more likely to hand you.
This distinction gets skipped constantly, and it changes the risk profile entirely.
Nationally, variable holders are split almost evenly between the two structures (Mortgage Professionals Canada, 2026 Consumer Survey). We generally favour the adjustable version, for a reason that fits this page’s whole argument: it tells you the truth in real time. A payment that never moves while your amortization silently grows is a comfort that costs money.
There was a period when choosing variable meant qualifying at a lower rate and therefore borrowing more. That’s gone. You qualify at the higher of your contract rate plus 2% or 5.25% either way. Variable doesn’t buy approval room anymore, which usefully strips one bad reason out of the decision — nobody should be choosing a rate type to squeeze into a bigger house.
On our files it comes down to four questions, in this order:
Fixed versus variable is roughly 85% of what we’re asked about and the part where a broker’s real value shows — not because we know the future, but because we’ve watched several hundred versions of this decision play out and know which regrets are common.
Everything above points at the same conclusion: this question doesn’t have a right answer, it has your answer, and anyone who gives you one without asking about your life is guessing in a confident voice.
A teacher with tenure, a modest mortgage and no intention of moving for fifteen years is in a genuinely different position from a commissioned salesperson who already suspects the house is too small. A couple planning a baby in two years is not the same file as empty-nesters planning to downsize. Someone whose income arrives in irregular lumps needs different structure from someone paid on the fifteenth and the thirtieth. Same rates, same day, same lenders available — three different correct decisions.
That’s the whole reason we build a plan around the file instead of quoting a rate down the phone. The rate is the easiest part of this to shop and the least likely part to determine what your mortgage actually costs you. The structure around it — term length, penalty formula, prepayment privileges, whether you can leave and what it costs when you do — is where the money hides, and it can only be chosen once someone understands what your next five years probably look like.
Over long stretches of Canadian history, variable has cost less more often than not. That’s a real finding and it’s also close to useless for you personally, because you aren’t living an average — you’re living one five-year term, once. Research on multi-decade averages cannot tell you what happens in your term.
Anyone who tells you confidently which way to go based on where rates are headed is guessing with conviction. We’d rather build the decision on the things that are actually knowable.
This decision doesn’t happen once. It comes back at every renewal, with different numbers and a different life around it — which makes it a relationship question as much as a rate one. See choosing a mortgage broker for renewals and refinancing in BC.
The honest answer is that it depends on facts about you, not forecasts about rates. Fixed suits fixed budgets, long horizons, and low tolerance for payment movement. Variable suits files with a real chance of changing mid-term, because breaking a variable almost always costs three months' interest while breaking a fixed can cost the interest rate differential — frequently several times more. Decide on your own likelihood of breaking, your capacity to absorb increases, your time horizon, and only then the size of the rate gap.
The exit cost, which almost nobody discusses at signing. A variable penalty is almost always three months' interest. A fixed penalty is the greater of three months' interest or the interest rate differential, and on a real discharge statement we published the IRD ran four times the three-months' calculation. Variable can also usually be converted to a fixed mid-term, while a fixed cannot become variable. Both are stress tested identically.
Yes, in two concrete ways. The penalty to break is almost always three months' interest rather than an interest rate differential that can run several times larger, so exiting early costs dramatically less. And the conversion option runs one way: you can move from a variable to a fixed mid-term, but you cannot move from a fixed to a variable. Choosing variable keeps both doors open for the whole term. That flexibility has real cash value for anyone who might sell, refinance, separate, relocate or restructure before the term ends — which happens far more often than a five-year contract implies. In our own practice, roughly four out of five mortgages we fund are refinances or switches rather than first purchases.
Treat the gap as a price rather than a prediction. On a $600,000 mortgage with a 0.65% spread, choosing fixed costs roughly $3,900 more in interest in the first year — about $325 a month. The useful question is whether that is a fair price for not thinking about your mortgage for five years. For many households it is. For someone likely to sell or refinance mid-term, it buys certainty they will never use while the penalty structure costs them more on exit.
With an adjustable-rate mortgage your payment moves when prime moves, so your amortization stays on schedule. With a variable-rate mortgage with a set payment, the payment stays flat and the split between principal and interest shifts instead — which feels calmer until rates rise enough to approach your trigger rate, at which point your amortization stretches. Canadian variable holders are split almost evenly between the two structures. We generally favour the adjustable version because it reports reality in real time.
Usually yes — most variable products allow conversion to a fixed at the lender's then-current rates. Two cautions: the rate you convert into is whatever is available that day, not the rate you were originally offered, and the fixed you convert to may carry the lender's posted rate rather than a discounted one. Conversion is a genuine safety valve, but it isn't a free option, and it doesn't work in reverse — a fixed cannot become variable.
Not anymore. You qualify at the higher of your contract rate plus 2% or 5.25% regardless of whether the mortgage is fixed or variable. There was a period when variable meant qualifying at a lower rate and borrowing more, and that is no longer the case — which usefully removes one of the worst reasons to pick a rate type.
It carries a different risk, not simply more of it. Variable exposes you to payment or amortization movement during the term. Fixed exposes you to renewal risk at the end of the term and to a much larger penalty if you need to exit early. Households that broke a five-year fixed in 2022 and 2023 discovered that the safe choice carried a cost nobody had explained at signing. The right framing is which risk you are better positioned to carry.
This decision is worth twenty minutes and a real conversation, not a coin toss at signing. Our BC mortgage calculator suite will show you the payment difference at today’s gap, the penalties page shows what each side genuinely costs to exit, and how mortgages actually work covers the mechanics underneath both.
