Canadian mortgage borrowers are navigating a more volatile rate environment than they’ve seen in years, as bond market turbulence pushes fixed mortgage rates higher even though the Bank of Canada has kept its policy rate unchanged since early September. The result is a widening split between fixed and variable products, and a growing debate among economists over whether the central bank can hold the line much longer.
Bond Yields Driving Fixed Rates Higher
Canada’s five-year government bond yield, the benchmark that lenders use to price fixed mortgages, rose by about a quarter of a percentage point over a single week in mid-September, according to Canadian Mortgage Trends. Clinton Wilkins of Clinton Wilkins Mortgage Team said lenders responded with increases ranging from 20 to nearly 100 basis points, calling the pricing environment “all over the place.” Ron Butler of Butler Mortgage noted that beyond published rate hikes of 10 to 20 basis points at several major banks, many lenders also pulled discretionary discounts, meaning some borrowers effectively faced increases closer to 40 basis points.
David Larock of Integrated Mortgage Planners pointed to energy-driven inflation fears tied to renewed hostilities between the United States and Iran, along with concerns about the scale of U.S. government debt, as key forces pushing yields higher. The Congressional Budget Office projects U.S. federal net interest costs will exceed $1 trillion in 2026. By late September, Dr. Sherry Cooper, chief economist at Dominion Lending Centres, said the five-year Canadian yield had jumped 14 basis points in a single day — a move she described as “unheard of.”
Bank of Canada Holds, but for How Long
The Bank of Canada kept its overnight rate at 2.25% on September 2, its seventh consecutive hold, with the next scheduled announcement set for October 28. Statistics Canada put August inflation at 3%, above the Bank’s 2% target, while core inflation measures have remained closer to that target domestically.
Economists are split on what comes next. TD deputy chief economist Derek Burleton told MortgageFest Canada in Toronto that “the case for hiking is not that compelling,” arguing markets are wrong to assume the Bank of Canada must follow the U.S. Federal Reserve, which raised its benchmark rate by 25 basis points on September 16 — its first hike since 2023. Burleton put roughly 50% odds on the Bank of Canada holding steady through the rest of the year, with his alternative scenario involving one hike and a maximum of two.
Cooper takes a more hawkish view, telling the Women in Mortgage Summit Canada that she now expects the Bank of Canada will be “forced” into raising rates, likely later this year or in the first half of next year, citing a global selloff in U.S. Treasuries and tariff-driven price pressure at home. National Bank and Scotiabank, she noted, are already projecting a move to 2.50% at the October meeting. Questrade’s Tanya Woods offered a similar read, saying “rates will probably rise, but they’re trying to hold as long as possible.”
Key Figures Shaping Canada's Mortgage Rate Environment
Fixed vs Variable: The Widening Gap
As bond yields climb while the policy rate stays put, the spread between fixed and variable mortgage pricing has widened to roughly a full percentage point, with some five-year fixed rates now sitting about that much above comparable variable rates. Butler said that threshold matters for borrower decisions: “once we see a full 1% delta between fixed and variable — and certainly once we exceed 1% — then I think you just have to tell your clients, if you’ve got the stomach for it, you should consider variable.”
Larock cautioned that locking into a fixed rate immediately after a yield spike carries its own risk, since geopolitical developments that drove yields up — such as disruptions tied to the conflict between the United States and Iran — could just as easily reverse. “If you lock in a 5-year fixed rate today for five years, and the Strait of Hormuz reopens in a month, you’re stuck with that rate,” he said.
What It Means for the Housing Market
The rate backdrop is unfolding against a housing market that Burleton described as having found its bottom after a correction of more than 20% in prices over four years of cooling. In Ontario specifically, prices were down about 3% year over year in recent months, he said, though he pushed back against expectations of a sharp rebound, predicting instead “a fairly flat outlook for sales and prices.” TD expects national mortgage volumes to grow by 4% to 5% over the next two to three years, which Burleton called “moderate, sustainable, healthy,” while cautioning that the condo segment may not fully recover until 2027 or 2028 given ongoing supply overhang. Detached and semi-detached markets, by contrast, are showing earlier signs of price stabilization across the Greater Toronto Area.
