Canada Housing Market

Canadian mortgage borrowers may be facing renewed rate pressure, even as underlying inflation shows signs of cooling.

According to BMO commentary highlighted by Better Dwelling, long-term Government of Canada bond yields have climbed to their highest level since 2010, raising concerns that borrowing costs could remain elevated or move higher.

Long-Term Bond Yields Hit a 2010 High

Government bond yields matter because they help set the benchmark for borrowing costs across the economy.

BMO chief economist Douglas Porter noted that the 30-year Government of Canada bond yield briefly moved above 4.05%, marking its highest level since 2010.

For comparison, BMO said the same yield averaged just under 2% from early 2015 to early 2022.

That shift suggests Canada may be moving further away from the ultra-low-rate environment that shaped the housing market for much of the past decade.

Why Bond Yields Matter for Mortgages

Bond yields are especially important for fixed mortgage rates.

When Government of Canada bond yields rise, lenders often face higher funding costs. Those costs can eventually be passed on to borrowers through higher mortgage rates.

This means rising bond yields can affect:

• Fixed mortgage rates
• Mortgage affordability
• Buyer purchasing power
• Housing market demand
• Renewal costs for existing homeowners

Even if the Bank of Canada does not raise its policy rate, mortgage rates can still move higher if bond yields rise.

Inflation Is Cooling, But Borrowing Costs Are Not

One of the more confusing parts of the current market is that core inflation appears to be easing, while long-term borrowing costs are still rising.

According to the report, BMO noted that the Bank of Canada’s preferred core inflation measures cooled in April. CPI trim fell to 2.0% annual growth, described as a five-year low and slightly below the pre-pandemic average.

Normally, slower core inflation would support expectations for lower rates.

Instead, bond markets appear more focused on rising oil prices and broader borrowing risks.

Oil Prices Are Adding Pressure

BMO pointed to sustained upward pressure on oil prices as a key concern for bond markets.

Higher oil prices can feed into headline inflation, which may make investors more cautious about long-term lending.

That matters for housing because inflation expectations can influence bond yields, and bond yields can influence mortgage rates.

Canada’s Debt Demand Is Also a Concern

The report also notes that inflation is not the only factor affecting yields.

Borrowing costs are also influenced by supply and demand in credit markets.

When governments, businesses, developers, landlords, households, and other borrowers all compete for capital, higher demand for debt can push yields upward.

That can make borrowing more expensive across the economy, including for mortgages and real estate financing.

What This Means for Buyers

For buyers, rising bond yields could make affordability more difficult.

If fixed mortgage rates climb, buyers may face:

• Higher monthly payments
• Lower mortgage qualification amounts
• Less purchasing power
• More pressure to delay buying decisions

This is especially important in expensive markets where affordability is already stretched.

What This Means for Homeowners Renewing Mortgages

Rising yields also matter for existing homeowners approaching renewal.

Many Canadians are already renewing mortgages at higher rates than they secured during the low-rate period.

If fixed rates rise further, renewal pressure could intensify for households that are already dealing with higher payments.

What This Signals for Canada’s Housing Market

The latest bond-yield move reinforces a key theme in Canadian real estate.

The housing market is still highly dependent on borrowing costs.

Even if inflation slows and the Bank of Canada holds rates steady, mortgage-rate pressure can continue through the bond market.

For Canada’s housing market, this could mean:

• Slower buyer demand
• Continued affordability pressure
• More cautious market activity
• A delayed housing recovery

What This Signals for Ontario

In Ontario, where home prices remain high and affordability is already strained, higher fixed mortgage rates could have a significant impact.

Buyers in the GTA and surrounding markets may become more cautious if mortgage rates rise again.

For sellers, this means pricing strategy remains important. If borrowing costs increase, buyers may have even less room to stretch their budgets.
