Fixed or variable at renewal, without pretending to know the future
Every article on this question secretly contains a forecast. This one does not. The honest version of the fixed versus variable decision is about how much payment uncertainty you can absorb, and what breaking the mortgage would cost you in each case.
Updated July 25, 2026The thing nobody will tell you
Whether fixed or variable wins over your next term is determined by future interest rate decisions. Nobody knows those. Any article that says otherwise is guessing with confidence.
Historically, variable rate mortgages have won more often than not in Canada, largely because borrowers paid a premium for the certainty of fixed. That is a statement about the past and it comes with an obvious caveat: the people who held variable through a rapid tightening cycle did not experience it as a win, whatever the long run averages said.
So the useful question is not which one will be cheaper. It is which one you can live with if you are wrong.
The Bank of Canada's target for the overnight rate was 2.25 per cent following the July 15, 2026 decision. The next scheduled announcement dates are September 2, October 28 and December 9, 2026. Variable mortgage rates move with prime, which follows this rate. Fixed rates follow bond yields.

What actually differs between them
| Fixed | Variable | |
|---|---|---|
| Rate over the term | Locked | Moves with prime |
| Payment | Stable | Either the payment changes, or the payment is fixed and the split between principal and interest changes, depending on the product |
| Typical break penalty | The higher of three months interest or the interest rate differential | Typically three months interest |
| Priced off | Government of Canada bond yields | Lender prime, which follows the Bank of Canada overnight rate |
| Convert mid term | Not usually to variable | Usually can convert to fixed, at the lender's rate at that time |
One nuance that trips people up: not all variable rate mortgages behave the same way when rates move. Some adjust your payment. Others hold the payment steady and change how much of it goes to principal, which is where trigger rates and extending amortisations come from. Ask your lender which type you are being offered, in those words.
The penalty difference almost nobody checks
If there is any chance you will break the mortgage before the term ends, because you might sell, move, separate or refinance, this section matters more than the rate.
FCAC's worked example: an outstanding balance of $200,000, a current interest rate of 6 per cent, 36 months left in a five year term, and a current posted rate of 4 per cent for a comparable 36 month term. Three months interest is approximately $3,000. The interest rate differential is approximately $12,000. You pay the higher of the two, which is $12,000, and there may also be an administration fee.

A closed variable rate mortgage generally carries a three months interest penalty instead. That difference is a real, quantifiable benefit of variable that has nothing to do with which way rates go, and it is routinely left out of the comparison because it is not a headline number.
FCAC also notes a legal backstop under the Interest Act: if your mortgage term is longer than five years and you have held it for at least five years, the maximum penalty is three months interest. That is one of the few reasons a term longer than five years is interesting.
A framework that needs no forecast
Work out your worst case payment
Take the variable rate you are being offered and add two or three percentage points. Calculate that payment. If it would break your budget, the question is answered: take fixed. Not because rates will rise, but because you cannot absorb it if they do.
Ask how likely you are to break the mortgage
Selling within the term, a likely relocation, a business that might need the equity, a relationship in flux. Any of those raises the value of the cheaper penalty, which favours variable.
Be honest about how much you will think about it
Some people watch every Bank of Canada announcement and find it interesting. Others will lose sleep. Payment certainty has a genuine value and it is not irrational to pay for it.
Compare the actual spread you are offered
If the fixed rate on offer is barely above the variable, you are buying certainty cheaply. If the gap is wide, you are paying a lot for it. Judge the price of the insurance, not the direction of rates.
For most households with a normal amount of financial slack and no plan to move, either choice is defensible and the difference over one term is smaller than the difference between negotiating your renewal and not negotiating it. Spend your energy on the rate you are offered and the term you pick, not on trying to out forecast the bond market.
Choosing the term is the bigger decision
Fixed versus variable gets the attention. How long you lock is often the more consequential choice, because it decides when you next get to renegotiate, and whether you are in the market at a moment of your choosing or theirs.
- A shorter term returns you to the negotiating table sooner, which is useful if you expect your circumstances to improve or if you think today's rates are unattractive. It also means doing this again sooner.
- A longer term buys certainty and reduces admin, and locks in whatever you signed, including the penalty structure, for longer.
- Matching the term to a known event is underrated. If you know you will sell in about three years, a three year term avoids a penalty rather than optimising a rate.
CMHC's most recent industry release noted that renewal volumes are expected to ease through 2026, while most borrowers renewing still face significant increases in interest costs, and that the national 90 plus day delinquency rate was 0.24 per cent in the fourth quarter of 2025. That is the backdrop. It argues for choosing a payment you can hold comfortably rather than the cheapest one you can technically qualify for.
Common questions
Is fixed or variable better in Canada right now?
There is no honest answer to that question in advance, because it depends entirely on what the Bank of Canada does over your term, which nobody knows. What can be answered honestly is which one suits your situation: variable if you can absorb payment changes and value the cheaper exit, fixed if payment certainty is worth paying for.
What is the penalty difference between fixed and variable?
It is often large. FCAC states that for a closed variable rate mortgage the penalty is typically three months interest on the outstanding balance, while for a closed fixed rate mortgage it is the higher of three months interest or the interest rate differential. In FCAC's own example the interest rate differential came to about $12,000 against $3,000 for three months interest.
What drives variable and fixed mortgage rates in Canada?
Variable rates move with lenders' prime rates, which follow the Bank of Canada's target for the overnight rate. Fixed rates are priced off Government of Canada bond yields of a similar term. That is why fixed rates can move in a week when the Bank of Canada has not met, and why the two do not move in step.
Can I switch from variable to fixed during my term?
Most Canadian variable rate mortgages allow you to convert to a fixed rate during the term, but the rate you convert to is set by your lender at that moment and is not necessarily their best advertised rate. Ask what the conversion rate would be based on before you rely on it as a safety net.
Does the stress test still apply if I stay with my current lender?
Your existing lender does not have to requalify you at the minimum qualifying rate to renew you into a comparable term. OSFI also does not require the minimum qualifying rate on a straight switch between federally regulated lenders where the amortisation and loan amount do not increase.
