Canada's five-year mortgage design is a rolling credit event

Canadian borrowers amortize over 25 years and lock their rate for five years or less, then renew at whatever the market offers, and that rhythm, IREI's report argues, makes the Canadian mortgage market run on a different clock from the U.S. one it superficially resembles. A Canadian homeowner is therefore a repeat borrower who reprices with every cycle, not a passive holder of a three-decade fixed liability; IREI notes that Canada and the United States share legal traditions and an appetite for homeownership, yet the credit architecture behaves almost in reverse of the American one.

That design choice changes how rate policy lands, because households returning to the market every few years transmit monetary policy to spending with unusual speed, and IREI flags the moment of truth. A July 2025 Bank of Canada analysis cited in the report finds roughly 60 percent of all outstanding Canadian mortgages were scheduled to renew across 2025 and 2026, much of that book written at the pandemic-era lows of 2020 and 2021; forecasters spent two years warning that the repricing would deliver a payment shock severe enough to trigger a cascade of defaults. For a private lender, the call comes due on a published schedule.

The 30-year fixed-rate mortgage that is the foundation of American housing finance essentially does not exist in Canada, and the American product is built to keep household payments fixed for decades while the Canadian product forces households back to market every few years. Canadian residential credit therefore looks less like a long-dated bond and more like a loan with a visible reset calendar, and allocators who underwrite Canadian mortgages with U.S. assumptions are pricing for the wrong duration.

The renewal wave is the operating rhythm of the system, just larger this time because of the pandemic-era vintage, and the market worth watching is the one where the borrower carries the rate risk and the calendar tells you when the payment changes. For a private lender, the Canadian renewal schedule is about as close to a predictable payment-shock calendar as North American housing credit offers. In 2026, it is arriving in bulk.
