Fixed vs variable mortgage at renewal in Canada (2026)

Renewal is your chance to choose again between a fixed and a variable rate. Here is how the two compare in October 2026, what the payment gap looks like on a real balance, and the risks that matter more than the headline rate.

Where rates stand (October 8, 2026)

  • The Bank of Canada held its policy rate at 2.25% on September 2, 2026. Its next scheduled decision is October 28, 2026.
  • Ratehub reports lenders’ prime rate at 4.45%.
  • The lowest advertised 5-year fixed rate on Ratehub was 4.34%, and the lowest 5-year variable was 3.40%. These are best-case insured rates and many borrowers will be quoted more.

Variable rates move with your lender’s prime rate, which follows the Bank of Canada. Fixed rates follow bond yields, so they can rise or fall even when the Bank holds.

FCAC warns that a variable rate with fixed payments may be riskier than it looks. When rates rise, more of each payment goes to interest. In extreme cases none of it reaches principal and the balance grows.

Worked example: $400,000 with 20 years left

Using the lowest advertised rates above on monthly payments, and assuming each rate stays the same for the full 5-year term:

$400,000 balance, 20-year amortization, 5-year term (estimates)
Fixed 4.34%Variable 3.40%
Monthly payment$2,487.89$2,294.47
Interest over 5 years$78,849.51$61,371.69
Balance after 5 years$329,576.11$323,703.49

If rates never moved, the variable rate would cost about $193.42 a month less and save roughly $17,478 in interest over the term. But variable rates do move. If the variable rate were one percentage point higher, at 4.40%, the payment on the same balance would be $2,500.51, slightly above the fixed payment. In other words, the variable option only keeps its edge if its rate rises by less than about one point on average over your term.

Our calculator uses semi-annual compounding for every example. Some variable mortgages compound differently, so your lender’s numbers may differ a little.

Questions to ask yourself

  • Could your budget handle a payment a few hundred dollars higher for a while?
  • Might you sell, move or refinance during the term? A lower penalty can matter more than a lower rate.
  • Would a shorter fixed term or a hybrid (part fixed, part variable) be a fair middle ground?
  • If you renew into a lower payment, could you keep paying the old amount to pay the loan off faster?

Frequently asked questions

Should I choose fixed or variable at mortgage renewal in 2026?

It depends on your budget and risk tolerance. On October 8, 2026, the lowest advertised 5-year variable rate on Ratehub (3.40%) was below the lowest 5-year fixed rate (4.34%), but variable payments can rise if prime goes up. A fixed rate gives a predictable payment for the whole term.

What is the Bank of Canada rate right now?

The Bank of Canada held its policy rate at 2.25% on September 2, 2026. Its next scheduled announcement is October 28, 2026.

Is it cheaper to break a variable mortgage than a fixed one?

Usually. Breaking a closed variable-rate mortgage typically costs three months’ interest, while a closed fixed-rate mortgage usually costs the higher of three months’ interest or the interest rate differential, which can be much larger.

What is the risk of a fixed-payment variable mortgage?

When rates rise, more of each fixed payment goes to interest. FCAC warns that in extreme cases none of the payment goes to principal and the amount you owe can grow.
