Most New Uninsured Mortgages Now Carry Rate Reset Risk Within Five Years
A borrower who signed a mortgage in March 2026 with a three-year fixed term will face renewal in March 2029, when the overnight rate could be higher or lower than it is now. Nobody knows. What is certain is that 85% of new uninsured mortgages originated in Q1 2026 will face that same uncertainty within five years, because they chose either a variable rate or a fixed term shorter than the traditional five-year standard.
The data comes from the Canada Mortgage and Housing Corporation's Spring 2026 residential mortgage industry report. This shift reflects a structural change in the market. The five-year fixed mortgage, which held majority market share as recently as 2020, now accounts for less than 15% of new uninsured originations. The rest of the market has moved to products that reprice sooner.
Why borrowers are choosing short horizons
The decision makes sense in a narrow context. Borrowers who locked in five-year fixed rates in 2023 or 2024, when the Bank of Canada's overnight rate sat at or above 4.5%, are now watching variable-rate holders benefit from cuts that began in mid-2024. A three-year term offers a compromise: protection from immediate volatility, but a renewal date close enough to capture lower rates if the central bank continues easing.
The yield curve has also flattened. In a normal environment, longer terms cost more because lenders demand a premium for locking in rates over time. But when the bond market expects falling rates, the premium shrinks or disappears. At various points in 2025 and early 2026, two-year and three-year fixed rates moved closer to five-year rates as the yield curve flattened. That pricing made the shorter term feel like a free option: nearly the same rate, but you get another crack at refinancing sooner.
What the concentration creates
The problem is not any individual decision. A borrower with 40% equity and stable income can handle a 200-basis-point rate increase at renewal without distress. The problem is that 85% of new uninsured borrowers are now making the same bet at the same time, which concentrates repricing risk in a way the Canadian mortgage market has not seen before.
When 85% of new mortgages reset within five years, rate changes reach household budgets faster. Rate cuts arrive sooner, which is helpful in a downturn. Rate hikes also arrive sooner. The Bank of Canada's inflation-targeting framework assumes a lag between policy changes and their economic effects. That lag shortens when the stock of mortgages turns over more frequently.
CMHC flags this as a risk to the broader system. The 2020, 2021 cohort of five-year fixed borrowers, who locked in rates below 2%, are renewing now into a 4, 5% environment. That shock is already working through the system. The 2026 cohort is building the next wave. If rates rise between now and 2029, the repricing happens sooner and affects more households than it would have under the old distribution.
The hidden trade
Short-term fixed products do offer one advantage: lower penalties for breaking the contract. A five-year fixed mortgage broken in year three typically carries an interest rate differential penalty that can run to five figures. A three-year term broken in year two costs less. For borrowers who expect to sell or refinance early, that flexibility has value.
A household on the five-year fixed term could budget for 60 months of payments without watching rate announcements. That predictability has been traded for optionality, and optionality only pays off if you guess the direction correctly. The traditional five-year fixed mortgage cost more in year one and year two, but it eliminated the guesswork.
The 85% figure applies to uninsured mortgages, which require at least 20% down. These borrowers have more equity cushion than insured buyers. But equity does not eliminate payment shock. It just gives you more time before the shock forces a sale.
