As Canadians shift to shorter terms, CMHC warns of growing exposure to interest rate changes
Since 2022, Canadian borrowers have been moving steadily away from the traditional five-year fixed-rate mortgage and toward shorter fixed terms and variable-rate products.
That shift may reflect a rational response to rate volatility, but it also means more households are now carrying a greater share of Canada's interest rate risk, and the implications extend well beyond monthly payments.
That is the central argument of a new analysis by Aled ab Iorwerth, Deputy Chief Economist at Canada Mortgage and Housing Corporation (CMHC), which examines how mortgage term choices shape not only individual borrowing costs but also the distribution of interest rate risk across the broader financial system.
"Mortgage term choices are about more than securing the lowest borrowing cost today," ab Iorwerth wrote.
"As economic uncertainty increases, mortgage terms can have important implications for a household's financial resilience and its exposure to future interest rate changes."
Matt Fabian of TransUnion Canada says tariffs are unlikely to significantly affect mortgage delinquency rates nationally, but some regions could see increased strain if trade-related job losses occur.https://t.co/kHSA1ecJap

A structural shift in how Canadians borrow
The pivot toward shorter terms became visible after the Bank of Canada began raising its policy rate aggressively in 2022. Before that cycle, the five-year fixed mortgage dominated the Canadian market.
In the years since, borrowers have moved toward one-to-four-year fixed terms and variable-rate options, with the shift most pronounced among uninsured borrowers, according to CMHC data.
The consequences are showing up in renewal data. CMHC's 2026 Mortgage Consumer Survey found that homeowners who renewed in the past 18 months reported an average payment increase of $375 a month, and 35% said that change created real financial pressure on their budget.
A further 25% of mortgage consumers said they had regrets about the mortgage characteristics they selected, a figure that illustrates how quickly an apparently routine financing decision can become a source of lasting financial strain.
For brokers tracking the fixed and variable rate debate on behalf of their clients, the survey results point to a gap between product selection at the time of origination and borrower preparedness when conditions change.
Risk that travels with the borrower
Canada's mortgage system is structurally different from those in the United States and much of continental Europe, where long-term fixed-rate products allow lenders, not households, to absorb the bulk of interest rate risk.
Countries such as Australia, New Zealand, and the United Kingdom operate more similarly to Canada, relying heavily on variable and short-term contracts.
The result is that Bank of Canada policy rate changes pass through to borrowers more rapidly here than in markets where 30-year fixed terms are the norm. That transmission speed works in borrowers' favour when rates fall, but amplifies exposure when they rise.
Mortgage professionals are now on the front lines of some of the most financially consequential conversations their clients have had in a generation and what borrowers can expect at renewal remains one of the most urgent questions in the industry.
Victor Tran, mortgage and real estate expert at Rates.ca, previously said that predictability continues to drive most borrowers toward fixed-rate products despite the narrowing rate gap.
"Most households are still opting for fixed because it offers predictability in an environment where rate direction isn't guaranteed," Tran said.
CMHC's Spring 2026 Residential Mortgage Industry Report noted that the trend toward shorter mortgage terms in recent years represents a departure from the traditional Canadian market standard, and CMHC's analysis of Canada's mortgage renewal cycle indicates that while the volume of renewals is easing, the financial adjustments for many households are far from over.
