Pandemic-era homeowners face steeper renewal costs as Canada's five-year bond yield tops 3.6%

Even higher Canadian mortgage payments ahead as bond yields climb, says thinktank

Canada's five-year Government of Canada (GoC) bond yield has climbed to 3.7%. That's more than three times the sub-1% levels that prevailed when millions of Canadians took out five-year fixed mortgages in 2020 and 2021.

Those mortgages are now coming due in what the C.D. Howe Institute calls "a vastly different environment," with higher payments ahead for renewing households across the country.

The yield surge has come alongside an even sharper rise in US bond yields, as markets price in higher inflation and ongoing uncertainty. Because Canadian and US bond markets are closely integrated, that upward pressure is tightening financial conditions at home even without a Bank of Canada rate move — the overnight rate has held at 2.25% since October 2025.

The 10-year GoC yield rose to 3.99% from 3.45% at the start of July, while the two-year climbed from 2.76% to 3.37% over the same period, according to Morningstar. A primary driver was the Iran war's effect on energy costs, which pushed Canada's inflation rate to 3.0% in August from 2.8% in June, stoking rate hike expectations and drawing Canada into the broader global bond selloff.

US Treasuries amplified the move: the 10-year climbed to 5.3% from 4.5%, its highest level since 2002, while the 30-year rose to 5.6% from 5.0%.

The lowest insured five-year fixed mortgage rate available as of October 7 stood at 4.34%, according to Ratehub.ca.

Renewal shock for pandemic-era borrowers

Approximately 33% of Canadian mortgage holders are expected to face higher monthly payments by the end of 2026, with 10% of those renewing variable-rate mortgages projected to see payments rise by more than 40%.

Early signs of financial strain are already emerging in credit data: mortgage delinquency balances rose 32% year-over-year nationally in the first quarter of 2026 and 52% in Ontario. according to Equifax Canada's Q1 2026 Market Pulse report.

The C.D. Howe Institute's October analysis flags the broader systemic dimension, saying, "for renewing households, that means higher payments, raising concerns about household finances and financial system stability."

What brokers are telling clients

Max Singh of TMG The Mortgage Group previously told Canadian Mortgage Professional: "When they contact us to ask questions about their mortgage renewal coming in September, October, November – before, I used to say, 'It's six of one and half a dozen of the other.' But if their 1.99% is coming up for renewal in September, their renewal rate going forward is going up in a quicker fashion than their current pricing."

Not all borrowers are struggling. Taz Zaide, a Toronto-based broker with 6ix Mortgage Group, told CMP that his renewal clients had largely managed the transition.

"All the clients that we've had who've been up for renewal have basically just been fine with qualification," he said.

For brokers advising renewal clients, the C.D. Howe Institute's analysis makes the central point plain: bond markets, not the overnight rate, are now the dominant force setting fixed mortgage costs, and they are moving in the wrong direction.
