Variable Mortgage Rates in Canada Now Trail Fixed by Up to 90 Basis Points
A borrower qualifying for a $450,000 mortgage today faces a monthly payment difference of roughly $350 between a five-year fixed at 4.6% and a variable at 3.3%. Over five years, that's $21,000. The question is whether that gap stays wide enough to justify the volatility.
For the first time since early 2023, variable rates in Canada are priced meaningfully below fixed. The spread has widened as of September 2026, driven by two separate moves: the Bank of Canada cut its overnight rate to 2.25% by October 2025 and has held it there since, pulling prime down to 4.45%, while fixed rates, anchored to the five-year Government of Canada bond yield, have stayed elevated or climbed slightly due to inflation uncertainty and global bond market churn. Variable rates for insured mortgages now sit around prime minus 0.60% to 1.15%, landing most qualified borrowers between 3.30% and 3.85%. Fixed five-year terms are averaging 3.9% to 4.7%, depending on insurer status and lender.
That spread is the widest it's been in three years. It's also narrower than it sounds once you account for the option cost embedded in each product.
The lock-in asymmetry
Fixed rates are an insurance premium against rising rates. You pay more today in exchange for certainty. Variable rates are a bet on the path of monetary policy. If the Bank of Canada continues cutting or holds steady, the variable borrower wins. If inflation spikes and rates reverse, the variable borrower loses, but not symmetrically. The penalty for breaking a fixed mortgage early is calculated using the Interest Rate Differential, which can run into the tens of thousands for a borrower who needs to sell or refinance before maturity. The penalty for breaking a variable mortgage is three months of interest, typically $3,000 to $5,000 on a $400,000 balance.
That penalty gap is the hidden variable in the fixed-versus-variable decision. A borrower choosing fixed is paying a premium not only for rate certainty but also for the risk that life circumstances change and they need out. The IRD penalty can exceed the cumulative interest savings from locking in.
For a borrower with a stable five-year horizon, fixed makes sense if they believe the Bank of Canada will raise rates by at least 100 basis points over the term. For a borrower with any material chance of moving, refinancing, or switching lenders before five years, variable is cheaper even if rates rise moderately, because the exit cost is capped.
The payment structure trap
Most Canadian variable-rate mortgages are structured as "variable rate, fixed payment." The monthly payment stays constant. When prime drops, more of the payment goes to principal. When prime rises, more goes to interest. The monthly payment stays the same until prime rises so far that it no longer covers interest, at which point negative amortization kicks in and the lender forces a payment adjustment.
In practice, a borrower choosing variable today for the 130-basis-point discount will not see their monthly payment drop if prime falls further. They will simply pay off their mortgage faster. If they need the cash-flow relief, not just the long-term savings, the discount is less useful than it looks.
Adjustable-rate mortgages, where the payment changes immediately with prime, are available but rare in Canada. Most lenders do not offer them, and most brokers do not recommend them, because the payment shock risk is higher and the qualification rules are stricter under OSFI's stress test, which requires borrowers to qualify at the higher of 5.25% or their contract rate plus 200 basis points.
Where the spread tightens
The spread holds for insured mortgages with less than 20% down. For uninsured borrowers, the gap narrows. Lenders price uninsured fixed rates lower relative to insured, and uninsured variable rates higher, because the risk profile is different. An uninsured borrower with 25% down might see fixed at 4.4% and variable at 3.5%, a 90-basis-point spread.
The decision flips when the borrower expects to refinance within three years. At that horizon, the lower penalty cost of variable dominates the rate difference, even if the rate difference is only 50 basis points.
